Evaluating assessment

Exam A group of us at AU have begun discussions about how we might transform our assessment practices, in the light of the far-reaching AU Imagine plan and principles. This is a rare and exciting opportunity to bring about radical and positive change in how learning happens at the institution. Hard technologies influence soft more than vice versa, and assessments (particularly when tied to credentials) tend to be among the hardest of all technologies in any pedagogical intervention. They are therefore a powerful lever for change. Equally, and for the same reasons, they are too often the large, slow, structural elements that infest systems to stunt progress and innovation.

Almost all learning must involve assessment, whether it be of one’s own learning, or provided by other people or machines. Even babies constantly assess their own learning. Reflection is assessment. It is completely natural and it only gets weird when we treat it as a summative judgment, especially when we add grades or credentials to the process, thus normally changing the purpose of learning from achieving competence to achieving a reward. At best it distorts learning, making it seem like a chore rather than a delight, at worst it destroys it, even (and perhaps especially) when learners successfully comply with the demands of assessors and get a good grade. Unfortunately, that’s how most educational systems are structured, so the big challenge to all teachers must be to eliminate or at least to massively reduce this deeply pernicious effect. A large number of the pedagogies that we most value are designed to solve problems that are directly caused by credentials. These pedagogies include assessment practices themselves.

With that in mind, before the group’s first meeting I compiled a list of some of the main principles that I adhere to when designing assessments, most of which are designed to reduce or eliminate the structural failings of educational systems. The meeting caused me to reflect a bit more. This is the result:

Principles applying to all assessments

  • The primary purpose of assessment is to help the learner to improve their learning. All assessment should be formative.
  • Assessment without feedback (teacher, peer, machine, self) is judgement, not assessment, pointless.
  • Ideally, feedback should be direct and immediate or, at least, as prompt as possible.
  • Feedback should only ever relate to what has been done, never the doer.
  • No criticism should ever be made without also at least outlining steps that might be taken to improve on it.
  • Grades (with some very rare minor exceptions where the grade is intrinsic to the activity, such as some gaming scenarios or, arguably, objective single-answer quizzes with T/F answers) are not feedback.
  • Assessment should never ever be used to reward or punish particular prior learning behaviours (e.g. use of exams to encourage revision, grades as goals, marks for participation, etc) .
  • Students should be able to choose how, when and on what they are assessed.
  • Where possible, students should participate in the assessment of themselves and others.
  • Assessment should help the teacher to understand the needs, interests, skills, and gaps in knowledge of their students, and should be used to help to improve teaching.
  • Assessment is a way to show learners that we care about their learning.

Specific principles for summative assessments

A secondary (and always secondary) purpose of assessment is to provide evidence for credentials. This is normally described as summative assessment, implying that it assesses a state of accomplishment when learning has ended. That is a completely ridiculous idea. Learning doesn’t end. Human learning is not in any meaningful way like programming a computer or storing stuff in a database. Knowledge and skills are active, ever-transforming, forever actively renewed, reframed, modified, and extended. They are things we do, not things we have.

With that in mind, here are my principles for assessment for credentials (none of which supersede or override any of the above core principles for assessment, which always apply):

  • There should be no assessment task that is not in itself a positive learning activity. Anything else is at best inefficient, at worst punitive/extrinsically rewarding.
  • Assessment for credentials must be fairly applied to all students.
  • Credentials should never be based on comparisons between students (norm-referenced assessment is always, unequivocally, and unredeemably wrong).
  • The criteria for achieving a credential should be clear to the learner and other interested parties (such as employers or other institutions), ideally before it happens, though this should not forestall the achievement and consideration of other valuable outcomes.
  • There is no such thing as failure, only unfinished learning. Credentials should only celebrate success, not punish current inability to succeed.
  • Students should be able to choose when they are ready to be assessed, and should be able to keep trying until they succeed.
  • Credentials should be based on evidence of competence and nothing else.
  • It should be impossible to compromise an assessment by revealing either the assessment or solutions to it.
  • There should be at least two ways to demonstrate competence, ideally more. Students should only have to prove it once (though may do so in many ways and many times, if they wish).
  • More than one person should be involved in judging competence (at least as an option, and/or on a regularly taken sample).
  • Students should have at least some say in how, when, and where they are assessed.
  • Where possible (accepting potential issues with professional accreditation, credit transfer, etc) they should have some say over the competencies that are assessed, in weighting and/or outcome.
  • Grades and marks should be avoided except where mandated elsewhere. Even then, all passes should be treated as an ‘A’ because students should be able to keep trying until they excel.
  • Great success may sometimes be worthy of an award – e.g. a distinction – but such an award should never be treated as a reward.
  • Assessment for credentials should demonstrate the ability to apply learning in an authentic context. There may be many such contexts.
  • Ideally, assessment for credentials should be decoupled from the main teaching process, because of risks of bias, the potential issues of teaching to the test (regardless of individual needs, interests and capabilities) and the dangers to motivation of the assessment crowding out the learning. However, these risks are much lower if all the above principles are taken on board.

I have most likely missed a few important issues, and there is a bit of redundancy in all this, but this is a work in progress. I think it covers the main points.

Further random reflections

There are some overriding principles and implied specifics in all of this. For instance, respect for diversity, accessibility, respect for individuals, and recognition of student control all fall out of or underpin these principles. It implies that we should recognize success, even when it is not the success we expected, so outcome harvesting makes far more sense than measurement of planned outcomes. It implies that failure should only ever be seen as unfinished learning, not as a summative judgment of terminal competence, so appreciative inquiry is far better than negative critique. It implies flexibility in all aspects of the activity. It implies, above and beyond any other purpose, that the focus should always be on learning. If assessment for credentials adversely affects learning then it should be changed at once.

In terms of implementation, while objective quizzes and their cousins can play a useful formative role in helping students to self-assess and to build confidence, machines (whether implemented by computers or rule-following humans) should normally be kept out of credentialling. There’s a place for AI but only when it augments and informs human intelligence, never when it behaves autonomously. Written exams and their ilk should be avoided, unless they conform to or do not conflict with all the above principles: I have found very few examples like this in the real world, though some practical demonstrations of competence in an authentic setting (e.g. lab work and reporting) and some reflective exercises on prior work can be effective.

A portfolio of evidence, including a reflective commentary, is usually going to be the backbone of any fair, humane, effective assessment: something that lets students highlight successes (whether planned or not), that helps them to consolidate what they have learned, and that is flexible enough to demonstrate competence shown in any number of ways. Outputs or observations of authentic activities are going to be important contributors to that. My personal preference in summative assessments is to only use the intended (including student-generated) and/or harvested outcomes for judging success, not for mandated assignments. This gives flexibility, it works for every subject, and it provides unquivocal and precise evidence of success. It’s also often good to talk with students, perhaps formally (e.g. a presentation or oral exam), in order to tease out what they really know and to give instant feedback. It is worth noting that, unlike written exams and their ilk, such methods are actually fun for all concerned, albeit that the pleasure comes from solving problems and overcoming challenges, so it is seldom easy.

Interestingly, there are occasions in traditional academia where these principles are, for the most part, already widely applied. A typical doctoral thesis/dissertation, for example, is often quite close to it (especially in more modern professional forms that put more emphasis on recording the process), as are some student projects. We know that such things are a really good idea, and lead to far richer, more persistent, more fulfilling learning for everyone. We do not do them ubiquitously for reasons of cost and time. It does take a long time to assess something like this well, and it can take more time during the rest of the teaching process thanks to the personalization (real personalization, not the teacher-imposed form popularized by learning analytics aficionados) and extra care that it implies. It is an efficient use of our time, though, because of its active contribution to learning, unlike a great many traditional assessment methods like teacher-set assignments (minimal contribution) and exams (negative contribution).  A lot of the reason for our reticence, though, is the typical university’s schedule and class timetabling, which makes everything pile on at once in an intolerable avalanche of submissions. If we really take autonomy and flexibility on board, it doesn’t have to be that way. If students submit work when it is ready to be submitted, if they are not all working in lock-step, and if it is a work of love rather than compliance, then assessment is often a positively pleasurable task and is naturally staggered. Yes, it probably costs a bit more time in the end (though there are plenty of ways to mitigate that, from peer groups to pedagogical design) but every part of it is dedicated to learning, and the results are much better for everyone.

Letting go and staying close: presentation to GMR Institute of Technology, India, August 2020

Letting go and staying close

Here are my slides from a presentation I gave to GMR Institute of Technology, Rajam of Srikakulum District, Andhra Pradesh State, India, last week. I gave the presentation from a car, parked in a camp site in the midst of British Columbia, surrounded by mountains and lakes and forest, taking advantage of a surprisingly decent 4G connection via an iPad. It was sadly not interactive, but I hope that those present learned something useful (even if, as my presentation emphasized, they did not learn what I intended to teach).

The general gist of it is that, when teaching online, we need to let go because the in-person power we have in a classroom simply isn’t there. There are other consequences – the need to build community, to demonstrate caring, to accept and value the context of the learner, to accept and value the very many teachers that they will encounter apart from us.

A novel approach to protecting academic freedom of speech: allow it, but do not allow it to be heard

The faculty and professional staff union at Athabasca University, AUFA (the Athabasca University Faculty Association), has two mailing lists, one used for announcements from its exec committee, and one for discussions between its members. Given that most of us have barely any physical contact with one another at the best of times, and that there are no other technologies that are likely to reach even a fraction of all staff involved in teaching and research (the Landing AUFA group, for instance, has only about 40 out of a few hundred potential members) the latter is the primary vehicle through which we, as a community of practice, communicate, share ideas and news, and engage in discussions that help to establish our collective identity. It’s a classic online learning community using a very low threshold, simple, universally accessible technology.

There had been a debate on the discussion list for a few days over the past week on a contentious issue pitting academic freedom against the needs and rights of transgender people. As too often happens when the rights of disadvantaged minorities are involved, the conversation was getting toxic, culminating in a couple of faculty members directly and very unprofessionally abusing another, telling him to shut up and to stop displaying his ignorance. This is not behaviour worthy of anyone, let alone teachers (of all people), and something had to be done about it. At this point the obvious solution would have been for the managers of the list to discuss these abuses individually with those members, and/or for the individuals themselves to reflect on and apologize for their behaviour, and/or to open up the debate on the list about acceptable norms and approaches to de-escalating situations like this. Sadly, that’s not how the list managers responded. Very suddenly, and without any prior warning or discussion whatsoever, the union executive committee shut the entire discussion list down indefinitely, mercilessly nuking it with the following terse and uninformative message posted to the announcement list:

” Dear AUFA members,

Until further notice, AUFA is suspending the AUFA discussions list serv for review of harmful language and due to a high volume of complaints.”

Shocked by this baldly authoritarian response, I immediately sent a strong message of protest, that I tempered with recommendations about what would have been an appropriate approach to managing the problem, and suggestions about ways to move forward with alternative methods and tools in future. I received no reply. One long day later, however, the following message was posted to the announcement list:

” Dear AUFA members,

I want to update you on the situation with the AUFA discussions list serv.

AUFA is committed to protecting Academic Freedom. AUFA is equally committed to protecting Human Rights. AUFA did not make the decision to suspend the list serv lightly. As the entity legally responsible for the listserv, AUFA has an obligation to ensure the safety of its members.

The AUFA executive had a lengthy discussion about the purpose and usefulness of the AUFA listserv and is actively considering alternative methods and forums by which members might communicate with each other in the near future. “

That’s it. That’s the whole message. Clearly they did not discuss this with the people who were actually affected, or with those who had been abusive, and they certainly didn’t talk about it with the rest of us. The message itself is remarkably uninformative, raising far more questions than it answers. It reads to me as ‘you have been naughty children and we have decided to send you to your room to think about it’. But I think they must have been following a different discussion than the one I saw because, though there was certainly some unprofessional nastiness and some unsubtle arguments expressed (that were becoming far more refined as the discussion progressed – that’s how free and open debate is supposed to work), I did not spot any human rights abuses during the discussion, and the only abuse of academic freedom I could see was the decision to shut down the list itself. Removing the possibility of speech altogether is certainly a non-traditional approach to protecting freedom of speech.

Notice, too, that in both messages there is a synecdochal conflation of ‘AUFA’ and ‘the AUFA executive committee’. I’m pretty sure that, as a member of AUFA, I would know whether I had been part of such a decision. That’s a bit like a teacher shutting down an online course because someone was rude, then claiming that the class shut it down. It’s a subtle way of abnegating responsibility, suggesting that some technological entity did something when, in fact, it was done by very real and fully responsible people. AUFA did not do this, and AUFA did not make these decisions. A small group of actual, real human beings did it, all by themselves.

I sent a strongly worded (but respectful) response to that one too.

Who owns this?

I think it is clear that the mailing list is not owned by the union executive committee. They are custodians of it, stewards who run it on the behalf of everyone in the union. Shutting it down denies the members of the union their primary means of connection and debate, including debate about this very issue. The message is quite misleading about the AUFA exec’s responsibilities, too: though they do need to be attentive to illegal behaviours, they are not legally responsible for what other people say on the listserv. In fact, the explicit or implicit legal protections afforded to providers of such services are fundamental to allowing much of the Internet to work at all. This is why there is so much outrage and protest against Trump’s efforts to remove such protections in the US right now. And there are lots of ways of handling the problem, from direct personal communication to public debate to the establishment of rules or a social contract to calling in the police. Going nuclear on the service does not fulfill that responsibility at all; it simply evades it.

It is absolutely fair to claim that list managers do have a responsibility to the union members of helping to maintain a non-abusive, safe, supportive online community. However, shutting down the thing they have an obligation to preserve is not just neglect of that responsibility but the worst and most harmful thing they could possibly do to fulfill it. It is like protecting an endangered animal by shooting it.

Ironically, the final message posted on the now-dead discussion list ended with the line:

“One thing I vowed to myself… is that I would never let anyone stop me from saying what I have to say “

Well, that kept like milk.

I feel incensed, abused, and suddenly incredibly isolated from my university and my colleagues. My sense of loss is tangible and intense. It’s lucky that I do have other channels, like this one, to vent my frustration and to bring this to a broader audience. I hope this message gets to at least a few of those who, like me, are feeling cut off and disempowered and, if they have not done so already, that they loudly voice their concerns to those responsible.

Moving on

Unfortunately, though very low threshold and accessible to all, listservs are not great tools for hosting contentious debates. They are extremely soft technologies which means that, on the positive side, they are extremely flexible and very low threshold, but that therefore a great deal of additional process must be added manually by their participants in order to deal with them: distinguishing threads, choosing which to attend to, tracking conversations, managing archived messages, using appropriate subject lines, to name but a few.

Listservs are poor tools for achieving consensus and poor tools for argument. The push nature of the technology means it can be very intrusive but, equally, the fact that we control our mail filters means that it can be completely shut down and ignored, without other participants having any knowledge that their messages are falling on deaf ears. It’s a technology that allows everyone to shout at the same time so it’s unsurprising that it is fertile ground for misunderstandings, confusion, high emotions, and people who forget that they are talking to other people. The very simplicity that makes them so easy to engage with also makes it easier to forget the humans behind the messages. Unless individuals have taken pains to share things about themselves with their messages, there are not even pictures and profiles to serve as a reminder. Though web archives may be available, they are rarely if ever open for continued dialogue: though, in principle, one could reply to a message from months or years ago, that virtually never happens. This means that people tend rush to get their message across before the list moves on to some other topic, with all the risks that entails. It kind of has to be that way. Because of the push nature of the medium, if conversations were to persist then multiple parallel discussions would rapidly overwhelm everyone’s inbox and attention.

For all these reasons and more, as anyone who has ever tried to do so will be painfully aware, managing a mailing list used for open discussion, especially one (like this) that lacks a clear mandate, contract or terms of engagement, takes a lot of manual effort, a fair bit of ingenuity, and a lot of careful attention. When things get out of hand, those who run the list need to take active, timely, creative measures to defuse them. It’s hard but necessary work, that demands sensitivity, a forgiving nature, a willingness to accept abuse with very little chance of being thanked for your efforts and, often, willingness and availability to work far ouside a normal working day (this, as it happens, is also true of many approaches to online teaching). Unfortunately, no one in our union leadership seems willing or able to take on such management. If that’s the case, the solution is not to shut it down. The solution is to pass it on to someone else who can and will moderate it more caringly, perhaps to put some more resources into managing it and, perhaps, to participatively look into rules, norms, and other tools and procedures that might do the job better.

Moving further on

There are hundreds and maybe thousands of tools and methods that can better (or at least differently) support this kind of debate than a listserv. Even the humble threaded forum at least allows such discussions to be segmented and, for those upset by them, ignored. Some allow for threads or people to be (from an individual’s perspective) muted, and many allow forum owners to close discussions in a particular thread without killing the whole thing. Some go beyond crude threads, allowing richer cross-linking between messages and discussions. Some offer authoring help, like in-line searching of previous messages and direct linking to sources or, simple AI to warn when sentiments appear to run high. Many tools allow for simple tricks like karma points, thumbs up, and other low threshold ways of signalling agreement or disagreement, in a manner that shows collective sentiment without a high commitment or fear of reprisal, and that also signals whether a topic is interesting to the crowd without relying on a deluge of messages to show it. Some offer means to reach decisions, from simple votes to computer supported collaborative argumentation tools. Many allow for profiles and other signals of social presence that make the humans behind the messages more visible and salient. Some (blogs, say, like this one) allow for more focused subscribable discussions on specific themes that are managed and owned by the creator of the original post, and that are not as ephemeral as mailing lists. Some offer other tools like persistent shared bookmarks or filesharing that help to organize resources related to themes of debate. Some have recommender systems that show related posts and thus help to situate discussions, and to support connections back to previous discussions. Many have persistence so that learning is reified and searchable, not lost in a stream of thousands of other emails. Some allow for scheduling and time-limited discussions.

Equally, there are lots of process models for reaching consensus on social norms and acceptable behaviours, as well as ways of dealing with issues when they arise. Skills can be developed in stewardship and moderation so that problems are defused before they become severe, or not arise in the first place thanks to careful specification of ground rules or structuring of the process. There are plenty of books and papers on the subject (this is my favourite, especially now that it is free) that delve into great detail. There are ways of taking an holistic approach that takes into account the larger social ecosystem to (for instance) help to build social capital, use different tools for different functions, and so on.

All of these technologies, including process models, methods, and procedures, come with plentiful gotchas – Faustian bargains and monkeys’ paws that can easily cause more problems than they solve and that will never be ideal for all – so this is not a set of decisions that should be entered into lightly or without extensive consultation, participation, and analysis, and it should always be thought of as an ongoing process, never a finished solution. Clearly, it eventually needs to be done. In the meantime, if a listserv is all we have, then we should at least manage it properly. It is not acceptable to simply nuke the only tool we have, even if it is a weak one.

I do realize that union leadership is an extremely hard and often thankless job and, though I frequently feel very critical of things they do on my behalf,  especially when they adopt an archaic ‘us vs them’ vocabulary, I am thankful they do it. I very seldom voice my adverse opinions because I know they are trying to do their best for everyone, I am certainly not willing to take on the enormous commitments involved myself and, without their hard work and principled actions (regardless of occasions when they actively make things worse) we would, on average, be in a far worse place than we are today. However, the union leadership’s response to this has been outrageously authoritarian, disproportionate, insensitive, and deeply harmful, in direct opposition to everything a union should stand for. If this is a reflection of their values then they do not have either my trust or my support.

 

Postscript

Eventually, after nearly two days, I received a one-line personal reply to my original complaint telling me that the suspension of the list is temporary (this may be news to others in the union who have not been told this: you heard it here first, folks!) and that they will, at some unspecified point, be seeking input from members on communication preferences (not consultation, note, or participation, just input). No timelines were given. I am not satisfied with this.

Does technology lead to improved learning? (tl;dr: it's a meaningless question)

Students using computers, public domain, https://www.flickr.com/photos/internetarchivebookimages/19758917473/There have been (at least) tens of thousands of comparative studies on the effects of ‘technology’ on learning performed over the past hundred years or so. Though some have been slightly more specific (the effects of computers, online learning, whiteboards, eportfolios, etc) and some more sensible authors use the term ‘tech’ to distinguish things with flashing lights from technologies in general, nowadays it is pretty common to just use the term ‘technology’ as though we all know what the authors mean. We don’t. And neither do they.

It makes no more sense to ask whether (say) computers have a positive or negative effect on learning than to ask whether (say) pedagogies have a positive or negative effect on learning. Pedagogies (methods and principles of learning and teaching) are at least as much technologies as computers and their uses and forms are similarly diverse. Some work better than others, sometimes, in some contexts, for some people. All are soft technologies that demand we act as coparticipants in their orchestration, not just users of them. This means that we have to add stuff to them in order that they work. None do anything of interest by themselves – they must be orchestrated with (usually many) other tools, methods, structures, and so on in order to do anything at all. All can be orchestrated well (assuming we know what ‘well’ really means, and we seldom really do) or badly.

It is instructive to wonder why it is that, as far as I know, no one has yet tried to investigate the effects of transistors, or screws, or words, or cables on learning, even though they are an essential part of most technologies that we do see fit to research and are certainly prerequisite parts of many educational interventions. The answer is, I hope, obvious: we would be looking at the wrong level of detail. We would be examining a part of the assembly that is probably not materially significant to learning success, albeit that, without them, we would not have other technologies that interest us more. Transistors enable computers, but they do not entail them.

Likewise computers and pedagogies enable learning, but do not entail it (for more on enablement vs entailment, see Longo et al, 2012 or, for a fuller treatment, Kauffman, 2019). True, pedagogies and computers may orchestrate many more phenomena for us, and some of those orchestrations may have more consistent and partly causal effects on whether an intervention works than screws and cables but, without considering the entire specific assembly of which they are a part, those effects are no more generalizably relevant to whether learning is effective or not than the effects of words or transistors.

Technologies enable (or sometimes disable) a range of phenomena, but only rarely do they generalizably entail a fixed set of outcomes and, if they do, there are almost always ways that we can assemble them with other technologies that alter those outcomes. In the case of something as complex as education, which always involves thousands and usually millions of technological components assembled with one another by a vast number of people, not just the teacher, every part affects every other. It is irreducibly complex, not just complicated. There are butterfly’s wing effects to consider – a single injudicious expletive, say, or a even a smile can transform the effectiveness or otherwise of teaching. There’s emergence, too. A story is not just a collection of words, a lesson is not just a bunch of pedagogical methods, a learning community is not just a collection of people. And all of these things – parts and emergent or designed combinations of parts – interact with one another to lead to deterministic but unprestatable consequences (Kauffman, 2019).

Of course, any specific technology applied in a specific context can and will entail specific and (if hard enough) potentially repeatable outcomes. Hard technologies will do the same thing every time, as long as they work. I press the switch, the light comes on. But even for such a simple, hard technology, you cannot from that generalize that every time any switch is pressed a light will come on, even if you, without warrant, assume that the technology works as intended, because it can always be assembled with other phenomena, including those provided by other technologies, that alter its effects. I press many switches every day that do not turn on lights and, sometimes, even when I press a light switch the light does not come on (those that are assembled with smart switches, for instance). Soft technologies like computers, pedagogies, words, cables, and transistors are always assembled with other phenomena. They are incomplete, and do not do anything of interest at all without an indefinitely large number of things and processes that we add to them, or to which we add them, each subtly or less subtly different from the rest. Here’s an example using the soft technology of language:

  • There are countless ways I could say this.
  • There are infinitely many ways to make this point.
  • Wow, what a lot of ways to say the same thing!
  • I could say this in a vast number of ways.
  • There are indefinitely many ways to communicate the meaning of what I wish to express.
  • I could state this in a shitload of ways.
  • And so on, ad infinitum.

This is one tiny part of one tiny technology (this post). Imagine this variability multiplied by the very many people, tools, methods, techniques, content, and structures that go into even a typical lesson, let alone a course. And that is disregarding the countless other factors and technologies that affect learning, from institutional regulations to interesting news stories or conversations on a bus.

Reductive scientific methods like randomized controlled tests and null hypothesis significance testing can tell us things that might be useful to us as designers and enactors of teaching. We can, say, find out some fairly consistent things about how people learn (as natural phenomena), and we can find out useful things about how well different specific parts compare with one another in a particular kind of assembly when they are supposed to do the same job (nails vs screws, for instance). But these are just phenomena that we can use as part of an assembly, not prescriptions for successful learning. The question of whether any given type of technology affects learning is meaningless. Of course it does, in the specific, because we are using it to help enable learning. But it only does so in an orchestrated assembly with countless others, and that orchestration is and must always be substantially different from any other. So, please, let’s all stop pretending that educational technologies (including pedagogical methods) can be researched in the same reductive ways as natural phenomena, as generalizable laws of entailment. They cannot.

Bananas as educational technologies

  Banana Water Slide banana statue, Virginia Beach, Virginia One of my most memorable learning experiences that has served me well for decades, and that I actually recall most days of my life, occurred during a teacher training session early in my teaching career. We had been set the task of giving a two-minute lecture on something central to our discipline. Most of us did what we could with a slide or two and a narrative to match in a predictably pedestrian way. I remember none of them, not even my own, apart from one. One teacher (his name was Philippe) who taught sports nutrition, just drew a picture of a banana. My memory is hazy on whether he also used an actual banana as a prop: I’d like to think he did. For the next two minutes, he then repeated ‘have a banana’ many times, interspersed with some useful facts about its nutritional value and the contexts in which we might do so. I forget most of those useful facts, though I do recall that it has a lot of good nutrients and is easy to digest. My main takeaway was that, if we are in a hurry in the morning, not to skip breakfast but to eat a banana, because it will keep us going well enough to function for some time, and is superior to coffee as a means of making you alert. His delivery was wonderful: he was enthusiastic, he smiled, we laughed, and he repeated the motif ‘have a banana!’ in many different and entertaining ways, with many interesting and varied emphases. I have had (at least) a banana for breakfast most days of my life since then and, almost every time I reach for one, I rememember Philippe’s presentation. How’s that for teaching effectiveness?

But what has this got to do with educational technologies? Well, just about everything.

As far as I know, up until now, no one has ever written an article about bananas as educational technologies. This is probably because, apart from instances like the one above where bananas are the topic, or a part of the topic being taught, bananas are not particularly useful educational technologies. You could, at a stretch, use one to point at something on a whiteboard, as a prop to encourage creative thinking, or as an anchor for a discussion. You could ask students to write a poem on it, or calculate its volume, or design a bag for it. There may in fact be hundreds of distinct ways to use bananas as an educational technology if you really set your mind to it. Try it – it’s fun! Notice what you are doing when you do this, though. The banana does provide some phenomena that you can make use of, so there are some affordances and constraints on what you can do, but what makes it an educational technology is what you add to it yourself. Notwithstanding its many possible uses in education, on balance, I think we can all agree that the banana is not a significant educational technology.

Parts and pieces

Here are some other things that are more obviously technological in themselves, but that are not normally seen as educational technologies either:

  • screws
  • nails
  • nuts and bolts
  • glue

Like bananas, there are probably many ways to use them in your teaching but, unless they are either the subject of the teaching or necessary components of a skill that is being learned (e.g. some crafts, engineering, arts, etc) I think we can all agree that none of these is a significant educational technology in itself. However, there is one important difference. Unlike bananas, these technologies can and do play very significant roles in almost all education, whether online or in-person. Without them and their ilk, all of our educational systems would, quite literally, fall apart. However, to call them educational technologies would make little sense because we are putting the boundaries around the wrong parts of the assembly. It is not the nuts and bolts but what we do with them, and all the other things with which they are assembled, that matters most. This is exactly like the case of the banana.

Bigger pieces

This is interesting because there are other things that some people do consider to be sufficiently important educational technologies that they get large amounts of funding to perform large-scale educational research on them, about which exactly the same things could be said: computers, say. There is really a lot of research about computers in classrooms. And yet metastudies tend to conclude that, on average, computers have little effect on learning. This is not surprising. It is for exactly the same reason that nuts and glue, on average, have little effect on learning. The researchers are choosing the wrong boundaries for their investigations.

The purpose of a computer is to compute. Very few people find this of much value as an end in itself, and I think it would be less useful than a banana to most teachers. In fact, with the exception of some heavily math-oriented and/or computer science subjects, it is of virtually no interest to anyone.

The ends to which the computing they perform are put are another matter altogether. But those are no more the effect of the computer than the computer is the effect of the nuts and bolts that hold it together. Sure, these (or something like them) are necessary components, but they are not causes of whatever it is we do with them. What makes computers useful as educational technologies is, exactly like the case of the banana, what we add to them.

It is not the computer itself, but other things with which it is assembled such as interface hardware, software and (above all) other surrounding processes – notably the pedagogical methods – that can (but on average won’t) turn it into an educational technology. There are potentially infinite numbers of these, or there would be if we had infinite time and energy to enact them. Computers have the edge on bananas and, for that matter, nuts and bolts because they can and usually must embody processes, structures, and behaviours. They allow us to create and use far more diverse and far more complex phenomena than nuts, bolts, and bananas. Some – in fact, many – of those processes and structures may be pedagogically interesting in themselves. That’s what makes them interesting, but it does not make them educational technologies. What can make them educational technologies are the things we add, not the machines in themselves.

This is generalizable to all technologies used for educational purposes. There are hierarchies of importance, of course. Desks, classrooms, chairs, whiteboards and (yes) computers are more interesting than screws, nails, nuts, bolts, and glue because they orchestrate more phenomena to more specific uses: they create different constraints and affordances, some of which can significantly affect the ways that learning happens. A lecture theatre, say, tends to encourage the use of lectures. It is orchestrating quite a few phenomena that have a distinct pedagogical purpose, making it a quite significant participant in the learning and teaching process. But it and all these things, in turn, are utterly useless as educational technologies until they are assembled with a great many other technologies, such as (very non exhaustively and rather arbitrarily):

  • pedagogical methods,
  • language,
  • drawing,
  • timetables,
  • curricula,
  • terms,
  • classes,
  • courses,
  • classroom rules,
  • pencils and paper,
  • software,
  • textbooks,
  • whiteboard markers,
  • and so on.

None of these parts have much educational value on their own. Even something as unequivocally identifiable as an educational technology as a pedagogical method is useless without all the rest, and changes to any of the parts may have substantial impacts on the whole. Furthermore, without the participation of learners who are applying their own pedagogical methods, it would be utterly useless, even in assembly with everything else. Every educational event – even those we apparently perform alone – involves the coparticipation of countless others, whether directly or not.

The point of all this is that, if you are an educational researcher or a teacher investigating your own teaching, it makes no sense at all to consider any generic technology in isolation from all the rest of the assembly. You can and usually should consider specific instances of most if not all those technologies when designing and performing an educational intervention, but they are interesting only insofar as they contribute, in relationship to one another, to the whole.

And this is not the end of it. Just as you must assemble many pieces in order to create an educational technology, what you have assembled must in turn be assembled by learners – along with plenty of other things like what they know already, other inputs from the environment, from one another, the effects of things they do, their own pedagogical methods, and so on – in order to achieve the goals they seek. Your own teaching is as much a component of that assembly as any other. You, the learners, the makers of tools, inventors of methods, and a cast of thousands are coparticipants in a gestalt process of education.

This is one of the main reasons that reductive approaches to educational research that attempt to isolate the effects of a single technology – be it a method of teaching, a device, a piece of software, an assessment technique, or whatever – with the intent of generalizing some statement about it cannot ever work. The only times they have any value at all are when all the technologies in question are so hard, inflexible, and replicable, and the uses to which they are put are so completely fixed, well defined, and measurable that you are, in effect, considering a single specific technology in a single specific context. But, if you can specify the processes and purposes with that level of exactitude then you are simply checking that a particular machine works as it is designed to work. That’s interesting if you want to use that precise machine in an almost identical context, or you want to develop the machine itself further. But it is not generalizable, and you should never claim that it is. It is just part of a particular story. If you want to tell a story then other methods, from narrative descriptions to rich case studies to grounded theory, are usually much more useful.

Obsolescence and decay

Koristka camera  All technologies require an input of energy – to be actively maintained – or they will eventually drift towards entropy. Pyramids turn to sand, unused words die, poems must be reproduced to survive, bicycles rust. Even apparently fixed digital technologies rely on physical substrates and an input of power to be instantiated at all. A more interesting reason for their decay, though, is that virtually no technologies exist in isolation, and virtually all participate in, and/or are participated in by other technologies, whether human-instantiated or mechanical. All are assemblies and all exist in an ecosystem that affects them, and which they affect. If parts of that system change, then the technologies on which they depend may cease to function even though nothing about those technologies has, in itself, altered.

Would a (film) camera for which film is no longer available still be a camera? It seems odd to think of it as anything else. However, it is also a bit odd to think of it as a camera, given that it must be inherent to the definition of a camera that it can take photos. It is not (quite) simply that, in the absence of film, it doesn’t work. A camera that doesn’t take photos because the shutter has jammed or the lens is missing is still a camera: it’s just a broken camera, or an incomplete camera. That’s not so obviously the case here. You could rightly claim that the object was designed to be a camera, thereby making the definition depend on the intent of its manufacturer. The fact that it used to be perfectly functional as a camera reinforces that opinion. Despite the fact that it cannot take pictures, nothing about it – as a self-contained object – has changed. We could therefore simply say it is therefore still a camera, just one that is obsolete, and that obsolescence is just another way that cameras can fail to work. This particular case of obsolescence is so similar to that of the missing lens that it might, however, make more sense to think of it as an instance of exactly the same thing. Indeed someone might one day make a film for it and, being pedantic, it is almost certainly possible to cut up a larger format film and insert it, at which point no one would disagree that it is a camera, so this is a reasonable way to think about it. We can reasonably claim that it is still a camera, but that it is currently incomplete.

Notice what we are doing here, though. In effect, we are supposing that a full description of a camera – ie. a device to take photos – must include its film, or at least some other means of capturing an image, such as a CCD. But, if you agree to that, where do you stop? What if the only film that the camera can take demands processing that is not? What if is is a digital camera that creates images that no software can render? That’s not impossible. Imagine (and someone almost certainly will) a DRM’d format that relies on a subscription model for the software used to display it, and that the company that provides that subscription goes out of business. In some countries, breaking DRM is illegal, so there would be no legal way to view your own pictures if that were the case. It would, effectively, be the same case as that of a camera designed to have no shutter release, which (I would strongly argue) would not be a camera at all because (by design) it cannot take pictures. The bigger point that I am trying to make, though, is that the boundaries that we normally choose when identifying an object as a camera are, in fact, quite fuzzy. It does not feel natural to think of a camera as necessarily including its film, let alone also including the means of processing that film, but it fails to meet a common-sense definition of the term without those features.

A great many – perhaps most – of our technologies have fuzzy boundaries of this nature, and it is possible to come up with countless examples like this. A train made for a track gauge that no longer exists, clothing made in a size that fits no living person, printers for which cartridges are no longer available, cars that fail to meet emissions standards, electrical devices that take batteries that are no longer made, and so on. In each case, the thing we tend to identify as a specific technology no longer does what it should, despite nothing having changed about it, and so it is difficult to maintain that it is the same technology as it was when it was created unless we include in our definition the rest of the assembly that makes it work. One particularly significant field in which this matters a great deal is in computing. The problem occurs in every aspect of computing: disk formats for which no disk drives exist, programs written for operating systems that are no longer available, games made for consoles that cannot be found, and so on. In a modern networked environment, there are so many dependencies all the way down the line that virtually no technology can ever be considered in isolation. The same phenomenon can happen at a specific level too. I am currently struggling to transfer my websites to a different technology because the company providing my server is retiring it. There’s nothing about my sites that has changed, though I am having to make a surprising number of changes just to keep them operational on the new system. Is a website that is not on the web still a website?

Whatever we think about whether it remains the same technology, if it does not do what the most essential definition of that technology claims that it must, then a digital technology that does not adapt eventually dies, even though its physical (digital) form might persist unchanged. This is because its boundaries are not simply its lines of code. This both stems from and leads to fact that technologies tend to evolve to ever greater complexity. It is especially obvious in the case of networked digital technologies, because parts of the multiple overlapping systems in which they must participate are in an ever-shifting flux. Operating systems, standards, protocols, hardware, malware, drivers, network infrastructure, etc can and do stop otherwise-unchanged technologies from working as intended, pretty consistently, all the time. Each technology affects others, and is affected by them. A digital technology that does not adapt eventually dies, even though (just like the camera) its physical (digital) form persists unchanged. It exists only in relation to a world that becomes increasingly complex thanks to the nature of the beast.

All species of technology evolve to become more complex, for many reasons, such as:

  • the adjacent possibles that they open up, inviting elaboration,
  • the fact that we figure out better ways to make them work,
  • the fact that their context of use changes and they must adapt to it,
  • the fact other technologies with which they are assembled adapt and change,
  • the fact that there is an ever-expanding range of counter-technologies needed to address their inevitable ill effects (what Postman described as the Faustian Bargain of technology),  which in turn create a need for further counter-technologies to curb the ill effects of the counter technologies,
  • the layers of changes and fixes we must apply to forestall their drift into entropy.

The same is true of most individual technologies of any complexity, ie. those that consist of many interacting parts and that interact with the world around them. They adapt because they must – internal and external pressures see to that – and, almost always, this involves adding rather than taking away parts of the assembly. This is true of ecosystems and even individual organisms, and the underlying evolutionary dynamic is essentially the same. Interestingly, it is the fundamental dynamic of learning, in the sense of an entity adapting to an environment, which in turn changes that environment, requiring other entities within that environment to adapt in turn, which then demands further adaptation to the ever shifting state of the system around it. This occurs at every scale, and every boundary. Evolution is a ratchet: at any one point different paths might have been taken but, once they have been taken, they provide the foundations for what comes next. This is how massive complexity emerges from simple, random-ish beginnings. Everything builds on everything else, becoming intricately interwoven with the whole. We can view the parts in isolation, but we cannot understand them properly unless we view them in relation to the things that they are connected with.

Amongst other interesting consequences of this dynamic, the more evolved technologies become, the more they tend to be comprised of counter-technologies. Some large and well-evolved technologies – transport systems, education systems, legal systems, universities, computer systems, etc – may consist of hardly anything but counter-technologies, that are so deeply embedded we hardly notice them any more. The parts that actually do the jobs we expect of them are a small fraction of the whole. The complex interlinking between counter-technologies starts to provide foundations on which further technologies build, and often feed back into the evolutionary path, changing the things that they were originally designed to counter, leading to further counter-technologies to cater for those changes. 

To give a massively over-simplified but illustrative example:

Technology: books.

Problem caused: cost.

Counter-technology: lectures.

Problem caused: need to get people in one place at one time.

Counter-technology: timetables.

Problem caused: motivation to attend.

Counter-technology: rewards and punishments.

Problem caused: extrinsic motivation kills intrinsic motivation.

Counter-technology: pedagogies that seek to re-enthuse learners.

Problem caused: education comes to be seen as essential to future employment but how do you know that it has been accomplished?

Counter-technology: exams provide the means to evaluate educational effectiveness.

Problem caused: extrinsic motivation kills intrinsic motivation.

Solution: cheating provides a quicker way to pass exams.

And so on.

I could throw in countless other technologies and counter-technologies that evolved as a result to muddy the picture, including libraries, loan systems, fines, courses, curricula, semesters, printing presses, lecture theatres, desks, blackboards, examinations, credentials, plagiarism tools, anti-plagiarism tools, faculties, universities, teaching colleges, textbooks, teaching unions, online learning, administrative systems, sabbaticals, and much much more. The end result is the hugely complex, ever shifting, ever evolving mess that is our educational systems, and all their dependent technologies and all the technologies on which they depend that we see today. This is a massively complex system of interdependent parts, all of which demand the input of energy and deliberate maintenance to survive. Changing one part shifts others, that in turn shift others, all the way down the line and back again. Some are harder and less flexible than others – and so have more effect on the overall assembly – but all contribute to change.

We have a natural tendency to focus on the immediate, the local, and the things we can affect most easily. Indeed, no one in the entire world can hope to glimpse more than a caricature of the bigger picture and, being a complex system, we cannot hope to predict much beyond the direct effects of what we do, in the context that we do them. This is true at every scale, from teaching a lesson in a classroom to setting educational policies for a nation. The effects of any given educational intervention are inherently unknowable in advance, whatever we can say about average effects. Sorry, educational researchers who think they have a solution – that’s just how it is. Anyone that claims otherwise is a charlatan or a fool. It doesn’t mean that we cannot predict the immediate future (good teachers can be fairly consistently effective), but it does mean that we cannot generalize what they do to achieve it.

One thing that might help us to get out of this mess would be, for every change we make, to think more carefully about what it is a counter-technology for,  and at least to glance at what the counter-technologies we are countering are themselves counter-technologies for. It might just be that some of the problems they solve afford greater opportunities to change than their consequences that we are trying to cope with. We cannot hope to know everything that leads to success – teaching is inherently distributed and inherently determined by its context – but we can examine our practice to find out at least some of the things that lead us to do what we do. It might make more sense to change those things than to adapt what we do to their effects.

 

A simple phishing scam

If you receive an unexpected email from what you might, at first glance, assume to me, especially if it is in atrocious English, don’t reply to it until you have looked very closely at the sender’s email address and have thought very carefully about whether I would (in a million years) ask you for whatever help it wants from you.

Being on sabbatical, my AU inbox has been delightfully uncrowded of late, so I rarely look at it until I’ve got a decent amount of work done most days, and occasionally skip checking it altogether, but a Skype alert from a colleague made me visit it in a hurry a couple of days back. I found a deluge of messages from many of my colleagues in SCIS, mostly telling me my identity had been stolen (it hadn’t), though a few asked if I really needed money, or wanted my groceries to be picked up. This would be a surprising, given that I live about 1000km away from most of them. All had received messages in poorly written English purporting to be from me, and at least a couple of them had replied. One – whose cell number was included in his sig – got a phishing text almost immediately, again claiming to be from me: this was a highly directed and malicious attack.

The three simple tricks that made it somewhat believable were:

  1. the fraudsters had created a (real) Gmail account using the username, jondathabascauca. This is particularly sneaky inasmuch as Gmail allows you to insert arbitrary dots into the name part of your email address, so they turned this into jond.athabasca.ca@gmail.com, which was sufficiently similar to the real thing to fool the unwary.

  2. the crooks simply copied and pasted the first part of my official AU page as a sig, which is pretty odd when you look at it closely because it included a plain text version of the links to different sections on the actual page (they were not very careful, and probably didn’t speak English well enough to notice), but again looks enough like a real sig to fool someone glancing at it quickly in the midst of a busy morning.

  3. they  (apparently) only sent the phishing emails to other people listed on the same departmental bio pages, rightly assuming that all recipients would know me and so would be more likely to respond. The fact that the page still (inaccurately) lists me as school Chair probably probably means I was deliberately singled out.

As far as I know they have not extended the attacks further than to my colleagues in SCIS, but I doubt that this is the end of it. If they do think I am still the Chair of the school, it might occur to them that chairs tend to be known outside their schools too.

This is not identity theft – I have experienced the real thing over the past year and, trust me, it is far more unpleasant than this – and it’s certainly not hacking. It’s just crude impersonation that relies on human fallibility and inattention to detail, that uses nothing but public information from our website to commit good old fashioned fraud. Nonetheless, and though I was not an intended victim, I still feel a bit violated by the whole thing. It’s mostly just my foolish pride – I don’t so much resent the attackers as the fact that some of the recipients jumped to the conclusion that I had been hacked, and that some even thought the emails were from me. If it were a real hack, I’d feel a lot worse in many ways, but at least I’d be able to do something about it to try to fix the problem. All that I can do about this kind of attack is to get someone else to make sure the mail filters filter them out, but that’s just a local workaround, not a solution.

We do have a team at AU that deals with such things (if you have an AU account and are affected, send suspicious emails to phishing@athabascau.ca), so this particular scam should have been stopped in its tracks, but do tell me if you get a weird email from ‘me’.

E-Learn 2019 presentation – X-literacies: beyond digital literacy

Here are  my slides from E-Learn 2019, in New Orleans. The presentation was about the nature of technologies and their roles in communities (groups, networks, sets, whatever), their highly situated nature, and their deep intertwingling with culture. In general it is an argument that literacies (as opposed to skills, knowledge, etc) might most productively and usefully be seen as the hard techniques needed to operate the technologies that are required for any given culture. As well as clarifying the term and using it in the same manner as the original term “literacy”, this implies there may be an indefinitely large range of literacies because we are all members of an indefinitely large number of overlapping cultures. All sorts of possibilities and issues emerge from this perspective.

Abstract: Dozens, if not hundreds, of literacies have been identified by academic researchers, from digital- to musical- to health- to network- literacy, as well as combinatorial terms like new-, multi-, 21st Century-, and media-literacy. Proponents seek ways to support the acquisition of such literacies but, if they are to be successful, we must first agree what we mean by ‘literacy’. Unfortunately, the term is used in many inconsistent and incompatible ways, from simple lists of skills to broad characteristics or tendencies that are either ubiquitous or meaninglessly vague. I argue that ‘literacy’ is most usefully thought of as the set of learned techniques needed to participate in the technologies of a given culture. Through use and application of a culture’s techniques, increasing literacy also leads to increasing knowledge of the associated facts and adoption of the values that come with that culture. Literacy is thus contextually situated, mutates over time as a culture and its technologies evolve, and participates in that co-evolution. As well as subsuming and eliminating much of the confusion caused by the proliferation of x-literacies, this opens the door to more accurately recognizing the literacies that we wish to use, promote and teach for any given individual or group.

Incidentally…

It appears that 97% of American teachers actually believe in learning styles, by which I mean the belief that there are persistent traits describing how people learn that can be used to determine the best way to teach them. This is despite at least most, if not all, of the many scores of such theories existing somewhere between astrology and fairies in terms of evidence for their relevance or applicability in real life learning. Though there may be ever-shifting conditions under which we may at times prefer one or other of whatever learning styles the theory we like offers – this may be a source of the persisting appeal of the idea – there is no reliable evidence that this is in any way relevant to whether or not we will learn better or worse (whatever we think that means) when offered a learning experience that is tailored to that preference. It’s not by any means for want of trying – countless studies exist, and that’s not counting probably many more that never saw the light of day because they had only null results to report and so were not deemed worthy of publication – so the obvious conclusion to be drawn is that these theories are most likely false.

It wouldn’t be so worrying were it not that there is evidence that such beliefs are harmful to learners and, even if there were not, then the time, effort, and money put into trying to use them would be far better spent on things that actually might work.

In the extremely unlikely event that it were one day proven that an individual has a persistent style of learning that, when we teach to that style, consistently leads to improved learning (however we measure that), then it would be my duty as a teacher to try to teach them to learn in other ways, because here’s the thing: the real world in which we are and must be lifelong learners doesn’t come neatly packaged in ways that fit your learning style. We can all learn to learn in all the ways that I list above, and then some, and we can all become better and smarter by applying the right strategy at the right time. We therefore need to cultivate as many diverse learning strategies as we can, and learn when to use them. That’s just common sense which, as it happens and surprisingly enough, is itself a learning style, according to the 4MAT model.

Signals, boundaries, and change: how to evolve an information system, and how not to evolve it

primitive cell development

For most organizations there tend to be three main reasons to implement an information system:

  1.     to do things the organization couldn’t do before
  2.     to improve things the organization already does (e.g. to make them more efficient/cheaper/better quality/faster/more reliable/etc)
  3.     to meet essential demands (e.g. legislation, keep existing apps working, etc)

There are other reasons (political, aesthetic, reputational, moral, corruption/bribery/kickbacks, familiarity, etc) but I reckon those are the main ones that matter. They are all very good reasons.

Costs and debts

With each IT solution there will always be costs, both initial and ongoing. Because we are talking about technology, and all technologies evolve to greater complexity over time, the ongoing costs will inevitably escalate. It’s not optional. This is what is commonly described as the ‘technological debt’ but that is a horrible misnomer. It is not a debt, but the price we pay for the solutions we need. If we don’t do it, our IT systems decay and die, starved of their connections with the evolving business and global systems around them. It’s no more of a debt than the need to eat or receive medical care is a debt for living.

Thinking locally, not globally

When money needs to be saved in an organization, senior executives tend to look at the inevitably burgeoning cost of IT and see it as ripe for pruning. IT managers thus tend to be placed under extreme pressure to ‘save’ costs. IT managers might often be relieved about that because they are almost certainly struggling to maintain the customized apps already, unless they have carefully planned for those increased costs over years (few do). Sensibly (from their own local perspective, given what they have been charged with doing), they therefore tend to strip out customizations, then shift to baseline applications, and/or cloud-based services that offer financial savings or, at least, predictable costs, giving the illusion of control. Often, they wind up firing, repurposing, or not renewing contracts for development staff, support staff, and others with deep knowledge of the old tools and systems. This keeps the budget in check so they achieve the goals set for them.

Unfortunately, assuming that the organization continues to need to do what it has been doing up to that point, the unavoidable consequence is that things that computers used to do are now done by people in the workforce instead. When made to perform hard mechanical tasks that computers can and should do, people are invariably far more fallible, slow, inconsistent, and inefficient. Far more. They tend to be reluctant, too. To make things worse, these mundane repetitive tasks take time, and crowd out other, more important things that people need to do, such as the things they were hired for. People tend to get tired, angry, and frustrated when made to do mechanical things over which they have little agency, which reduces productivity much further than simply the time lost in doing them. To make matters even worse, there is inevitably going to be a significant learning curve, during which staff try to figure out how to do the work of machines. This tends to lead to inflated training budgets (usually involving training sessions that, as decades of research show, are rarely very effective and that have to be repeated), time to read documentation, and more time taken out of the working day. Creativity, ingenuity, innovation, problem-solving, and interaction with others all suffer. The organization as a whole consequently winds up losing many times more (usually by orders of magnitude) than they saved on IT costs, though the IT budget now looks healthy again so it is often deemed to be a success. This is like taking the wheels off a car then proudly pointing to the savings in fuel that result. Unfortunately, such general malaises seldom appear in budget reports, and are rarely accounted for at all, because they get lost in the work that everyone is doing. Often, the only visible signs that it has happened are that the organization just gets slower, less efficient, less creative, more prone to mistakes, and less happy. Things start to break, people start to leave, sick days multiply. The reputation of the organization begins to suffer.
 
This is usually the point that more radical large scale changes to the organization are proposed, again usually driven by senior management who (unless they listen very carefully to what the workforce is telling them) may well attribute the problems they are seeing to the wrong causes, like external competition. A common approach to the problem is to impose more austerity, thus delivering the killing blow to an already demoralized workforce. That’s an almost guaranteed disaster. Another common way to tackle it is to take greater risks, made all the more risky thanks to having just converted creative, problem-solving, inquisitive workers into cogs in the machine, in the hope of opening up new sources of revenue or different goals. When done under pressure, that seldom ends well, though at least it has some chance of success, unlike austerity. This vicious cycle is hard to escape from. I don’t know of any really effective way to deal with it once it has happened.

Thinking in systems

The way to avoid it in the first place is not to kill off and directly replace custom IT solutions with baseline alternatives. There are very good reasons for almost all of those customizations that have almost certainly not gone away: all those I mentioned at the start of the post don’t suddenly cease to apply. It is therefore positively stupid to simply remove them without an extremely deep, multifaceted analysis of how they are used and who uses them, and even then with enormous conservatism and care. However, you probably still want to get rid of them eventually anyway, because, as well as being an ever-increasing cost,  they have probably become increasingly out of line with how the organization and the world around it is evolving. Unless there has been a steady increase in investment in new IT staff (too rare), so much time is probably now spent keeping old systems going that there is no time to work on improvements or new initiatives. Unless more money can be put into maintaining them (a hard sell, though important to try) the trick is not to slash and burn, and definitely not to replace old customized apps with something different and less well-tailored, but to gently evolve towards whatever long-term solution seems sensible using techniques such as those I describe below. This has a significant cost, too, but it’s not usually as high, and it can be spread over a much longer period.
 

For example…

If you wish to move away from reliance on a heavily customized learning management system to a more flexible and adaptive learning ecosystem made of more manageable pieces, the trick is to, first of all, build connectors into and out of your old system (if they do not already exist), to expose as many discrete services as possible, and then to make use of plugin hooks (or similar) to seamlessly replace existing functions with new ones. The same may well need to be done with the new system, if it does not already work that way. This is the most expensive part, because it normally demands development time, and what is developed will have to be maintained, but it’s worth it. What you are doing, at an abstract level, is creating boundaries around parts that can be treated as distinct (functions, components, objects, services, etc) and making sure that the signals that pass between them can be understood in the same way by subsystems on either side of the boundary.

Open industry standards (APIs, protocols, etc) are almost essential here, because apps at both sides of the boundary need to speak the same language. Proprietary APIs are risky: you do not want to start doing this then have a vendor decide to change its API or its terms and conditions. It’s particularly dangerous to do this with proprietary cloud-based services, where you don’t have any control whatsoever over APIs or backends,  and where sudden changes (sometimes without even a notification that they are happening) are commonplace. It’s fine to use containers or virtual machines in the cloud – they can be replaced with alternatives if things go wrong, and can be treated much like applications hosted locally – and it’s fine to use services with very well defined boundaries, with standards-based APIs to channel the signals. It is also fine to build your own, as long as you control both sides of the boundary, though maintenance costs will tend to be higher.  It is not fine to use whole proprietary applications or services in the cloud because you cannot simply replace them with alternatives, and changes are not under your control. Ideally, both old and new systems should be open source so that you are not bound to one provider, you can make any changes you need (if necessary), and you can rely on having ongoing access to older versions if things change too fast.
 
Having done this, you have two main ways to evolve, that you can choose according to needs:

  1.  to gradually phase in the new tools you want and phase out the old ones you don’t want in the old system until, like the ship of Theseus, you have replaced the entire thing. This lets you retain your customizations and existing investments (especially in knowledge of those systems) for the longest time, because you can replace the parts that do not rely on them before tackling those that do. Meanwhile, those same fresh tools can start to make their appearance in whatever other new systems you are trying to build, and you can make a graceful, planned transition as and when you are ready. This is particularly useful if there is a great deal of content and learning already embedded in the system, which is invariably the case with LMSs. It means people can mostly continue to work the way they’ve always worked, while slowly learning about and transitioning to a new way of working.
  2.  to make use of some services provided by the old system to power the new one. For instance, if you have a well-established means of generating class lists or collecting assessment data that involves a lot of custom code, you can offer that as a service from the old tool to your new tool, rather than reimplementing it afresh straight away or requiring users to manually replace the custom functions with fallible human work. Eventually, once the time is right to move and you can afford it, you can then simply replace it with a different service, with virtually no disruption to anyone. This is better when you want a clean break, especially useful when the new system does things that the original could not do, though it still normally allows simultaneous operation for a while if needed, as well as the option to fall back to the old system in the event of a disaster.

There are other hybrid alternatives, such as setting up other systems to link both, so that the systems do not interact directly but via a common intermediary. In the case of an LMS migration, this might be a learning record store (LRS) or student record system, for instance. The general principle, though, is to keep part or all of the old system running simultaneously for however long it is needed, parcellating its tools and services, while slowly transitioning to the new. Of course, this does imply extra cost in the short term, because you now have to manage at least two systems instead of one. However, by phasing it this way you greatly reduce risk, spread costs over a timeframe that you control, and allow for changes in direction (including reversal) along the way, which is always useful. The huge costs you save are those that are hidden from conventional accounting – the time, motivation, and morale of the workforce that uses the system. As a useful bonus, this service-oriented approach to building your systems also allows you to insert other new tools and implement other new ideas with a greatly diminished level of risk, with fewer recurring costs, and without the one-time investment of having to deal with your whole monolithic codebase and data. This is great if you want to experiment with innovations at scale. Once you have properly modularized your system, you can grow it and change it by a process of assembly. It often allows you to offer more control to end users, too: for instance, in our LMS example you might allow individuals to choose between different approaches to a discussion forum, or content presentation, or to insert a research-based component without so many of the risks (security, performance, reliability, etc) normally associated with implementing less well-managed code.

Signals and boundaries

In essence, this is all about signals and boundaries. The idea is to identify and, if they don’t exist, create boundaries between distinct parts of systems, then to focus all your management efforts on the signals that pass across them. As long as the signals remain the same from both sides, what lies on either side of the boundaries can be isolated and replaced when needed. This happens to be the way that natural systems mainly evolve too, from organisms to ecosystems. It has done pretty good service for a good billion years or so.
