A $77 3D Printer is Unveiled! Say Hello to the Lewihe Play – 3DPrint.com

Posted , updated on

To be fair, there’s not much you could do with this $77 printer – it needs a fair bit more stuff added to it before it is fully functional, and more than a bit of assembly and skill is required to make it work. None-the-less, this is a sign of a more general trend. Good 3D printers that are easy to use (albeit mind-numbingly slow and not as reliable as 2D printers) are at least as affordable as laser printers used to be 10-15 years ago. They are increasing in quality, dropping in price, getting faster, becoming more flexible, and are getting closer to standard commodity items with each passing week. There is still a big leap in price from hobbyist machines that do fun and occasionally useful stuff (with some effort) to commercial machines that do really useful stuff (with relative ease), but the gap is closing fast. I want one.

Smart learning – a new approach or simply a new name? | Smart Learning

Posted , updated on

Kinshuk has begun a blog on smart learning and, in this post, defines what that means. I particularly like:

“ I have come to realize that while technology can help us in improving learning, a fundamental change is needed in the overall perception of educators and learners to see any real effect. Simply trying to create adaptive systems, intelligent systems, or any sort of mobile/ubiquitous environments is going to have only superficial impact, if we do not change the way we teach, and more importantly, the way we think of learning process (and assessment process).“ 

This very much echoes my own view. At least that fundamental change is needed in the context of formal education. Outside our ivory towers that fundamental change has already happened and continues to accelerate. Google Search, Wikipedia, Twitter, Reddit, StackExchange, Facebook and countless others of their net-enabled ilk are amongst the most successful learning technologies (more accurately, components of learning technologies) ever created, arguably up there with language and writing, ultimately way beyond printing or schools. 

Kinshuk goes on to talk of an ecosystem of technology and pedagogy, which I think is a useful way of looking at it. Terry Anderson, too, talks of the dance between technology and pedagogy with much the same intent. I agree that we have to take a total systems view of this. My own take on it is that pedagogies are technologies – learning technologies are simply those with pedagogies in the assembly, whether human-instantiated or embedded in tools. Technologies and pedagogies are not separate categories. Within the ecosystem there are many other technologies involved in the assembly apart from those we traditionally label as ‘learning technologies’ such as timetables, organizational structures, regulations, departmental roles, accreditation frameworks, curricula, organizational methods, processes and rituals, not to mention pieces like routers, protocols, software programs and whiteboards. But, though important, technologies are not the only objects in this ecology. We need to think of the entire ecosystem and consider things that are not technologies at all like friendship, caring, learning, creativity, belief, environment, ethics, and, of course, people. As soon as you get past the ‘if intervention x, then result y’ mindset that plagues much learning technology (and education) research, and start to see it as a complex adaptive system that is ultimately about what it means to be human, you enter a world of rich complexity that I think is far more productive territory. It’s an ecosystem that is filled not just with process but with meaning and value. 

On a more mundane and pragmatic note, I think it is worth observing that learning and accreditation of competence must be entirely separated – accreditation is an invasive parasite in this ecosystem that feeds on and consumes learning. Or maybe it is more like the effluent that poisons it. Either way, I’d prefer that accreditation should not be lumped under the ‘smart learning’ banner at all. ‘Smart accreditation’ is fine – I have no particular concerns about that, as a separate field of study. In some ways it is worthy of study in smart learning because of its effects. That is somewhat along the lines of studying oil spills when considering natural ecosystems.  Assessment (feedback, critical reflection, judgement, etc), on the other hand, is a totally different matter. Assessment is a critical part of almost any pedagogy worthy of the name and so of course must be part of a smart learning ecology. I’m not sure that it warrants a separate category of its own but it is certainly important. It is, however, highly dangerous to take the ‘easy’ next step of using it to assert competence, especially when that assertion becomes the reason for learning in the first place, or is used as a tool to manipulate learners. That is what predominantly drives education now, to the point that it threatens the entire ecosystem. 

That said, I’d like to think that it is possible that the paths of accreditation and assessment might one day rejoin because they do share copious commonalities. It would be great to find ways that the smart stuff we are doing to support learning might, as a byproduct, also be useful evidence in accreditation, without clogging up the whole ecosystem. Technologies like Caliper, TinCan, and portfolios offer much promise for that.

How Do You Motivate Kids To Stop Skipping School?

Posted , updated on

Not like this!

This article starts with the line ‘it seems like a no-brainer’  and indeed it is. The no-brainer solution to low attendance is to make the schools relevant, meaningful and interesting to the kids.

However, bizarrely, that is not what seemed obvious to the writer of the article, nor to the ones that carried out this harmful and doomed research, who thought the obvious answer was an incentive scheme, and inflicted it on 799 kids, mostly age 9. Basically, they told the kids they would get two pencils and a cute eraser if they turned up 85% of the time during the 38-day study.

It seems that they did not bother with a literature review because, had they done so, they would have found out right away that rewards are totally the opposite of what is needed to motivate kids to attend school. There is over 50 years of compelling evidence from research on motivation, in many fields and from many disciplines, that demonstrates this unequivocally and beyond any reasonable doubt. The only possible consequence of this intervention would be to demotivate the kids so that, at best, they might revert to former behaviours at the end of it, and that many would be even less likely to attend when it was over.

Unsurprisingly, this is exactly what they found. The reward program did indeed increase attendance while it was in effect  (this is the allure of behaviourism and why it still holds sway – it does achieve immediate results) and, when it was over, kids were indeed even less motivated to attend than they had been before, exactly as theory and empirical research predicts. In fact, many of the kids got off very lightly: formerly high attenders and those that were not great attenders before but that succeeded in getting the reward only fell back to baseline levels as soon as it was over, which is actually pretty good going. A more significant reward or longer study period might have had worse consequences. Unfortunately, the effects on the ones that were the real target (those who were initially low attenders, 60% of whom failed to meet the goal) was disastrous: once the intervention was over, these already at-risk kids were only a quarter as likely to attend as they had been before the intervention began.

One of the surprised researchers said:

“”I almost felt badly about what we had done,” she says. “That in the end, we should not have done this reward program at all.”

Almost? Seriously. This borders on child abuse. I generally think of research ethics boards as an arguably necessary evil but, when I hear that experiments like this are still going on, I could easily become a fan.

The new axis of evil — Canada: One third of American 8th graders think we live in a dictatorship

Posted , updated on

You could look at the ‘fact’ that a third of American 8th grade students think Canada is a dictatorship as just another tragi-comic indictment of the US educational system, or of the blindness of the US to the existence or validity of any other country, or of a failure to get the message across about Canada, or that the message about Stephen Harper’s style of government actually has got out, albeit in a slightly distorted form. All likely have a glimmer of truth.

But, actually, the headline from The Province newspaper is false: I am pretty sure that very few US 8th graders really think that Canada is a dictatorship. They just don’t know. It was just a vaguely plausible option on the MCQ (note that the actual candidate answer did not mention dictatorship, though it was implied), so they made a disinterested guess because that’s what they have been taught to do. There’s no belief implied at all.

Should a kid in early teenage know about the political systems of other countries? Why? On the whole, things matter if they matter to those around you, and/or because you are curious about how they work, and/or if it has relevance to things you do or want to do. it is far from clear that any of these conditions is true for the kids in question.  If it is forced down your throat with the threat of reward (or punishment) but no one you care about cares about it, it doesn’t inherently interest you, and it doesn’t address any actual need you have, then why on earth should you learn it? But why are the kids not interested enough to know this? The answer lies, I think, in the means used to discover what they do not know.

Exam - public domain

 

Educational systems that are designed to churn out kids that get the right answers on tests like this have two main options. The first is to build rich, curiosity-driven learning communities in which teachers and learners share the journey, enthusing one another, supporting one another, discovering paths, sharing delight in their discoveries, and overcoming challenges together. This is how learning happens lastingly, efficiently and meaningfully. But, and it’s a big but, such a path may not cover what will be on the test at the time the test needs to be taken. There’s a great deal of intrinsic reward in such a path for all concerned but the extrinisic reward structures (most especially those tests), for both teachers and students, tend to actively militate against it. It certainly doesn’t help when all (teachers and students) are forced to do the same thing at the same time in lock step, whether it makes sense, interests anyone or has any relevance or not. The second path to getting those test results is much more direct: apply coercion (reward or punishment) and make students ‘learn’ what will be on the test. With enough pressure, it can work well enough to get the required test results, even though in the process it has disempowered teachers and learners, forced them into a controller/controlled relationship in which maintenance of discipline becomes a major teaching function and, as a result and perhaps most heinously of all, has likely destroyed any innate and lasting interest in the topic for the vast majority of students. To add the final cherry on top, the vast majority of what has been ‘learned’ will be forgotten once the need to pass the test has passed. Only the greatest teachers and most passionately interested learners can overcome this systemic failing. It’s not the kids that are ignorant. It’s the people who designed and continue to support the system used to teach them.

Why do we not ban use of cellphones in online learning?

Posted , updated on

Banning mobile phones is cargo cult science is a good, laudably brief, dismissive, critical review of the dangerously-reported recently published study by the London School of Economics that, amongst other things, shows a correlation between banning of mobile phones in schools and improved grades. As the title of the post suggests, the report does not show that banning mobile phones in schools is what improves grades in any way at all, despite the fact that the report writers do seem to believe that this is what they have shown: indeed, they recommend banning mobile phones as a cost effective measure to improve grades! That is so opposite to the obvious conclusion it is not even funny. To me, it shows a terrible failure at a massive systemic level. It’s not cellphone use that’s the problem – it’s the teaching. More precisely, it’s the system of teaching. I am sure that the vast majority of individual teachers are doing wonders, under extremely adverse circumstances. But they are doing so in a completely broken system. 

The interesting thing for me is that this would never come up as an issue for online and distance learners. Well, almost never: perhaps occasionally, study guides might recommend you set aside undistracted time for some (not all) kinds of study and webinar leaders might suggest that participants switch off phones and other distractions. But this is only at most a bit of practical advice, not an edict.

The point here is that command-and-control teaching methods of traditional classrooms have no meaning or relevance in online learning. This makes it all the more odd that we continue to see substantially the same pedagogies being used for online teaching as those found in the over-controlling environment of teacher-led classrooms. Obvious culprits like lecture-based MOOCs are just the more visible tip of this weird bit of skeuomorphism but the general principle runs across the board from instructivist textbooks through more enlightened uses of social constructivist methods in discussion forums. Too often, implicitly or explicitly, we act under the illusion that how we teach is how people learn, as though we still had students trapped in a classroom, controlling (almost literally) their every move.  The unholy and inseparable continued twinning of fixed-length courses and the use of grades to drive student progress is very much to blame, though a lack of imagination doesn’t help. These technologies evolved because of the physics of classrooms, not because they are good ways to support learning. In almost every way, they are actually antagonistic to learning. Online learning can, does and should liberate learners, giving them control. So let’s stop teaching them as though we were the ones in charge. It is crazy that we should voluntarily shackle ourselves when there is absolutely no need for it.

Interview with George Siemens in AU student union's Voice magazine (part 3)

Posted , updated on

Final part of a three part interview with George Siemens (following from the  first and second parts), in which he describes some thoughts about the future and nature of educational systems, and in which he has some great stuff to say about motivation and assessment in particular. I like this:

“Make things relevant to students, but also give students an opportunity to write themselves into the curriculum. That is, to be able to see the outcome of the benefits, the way in which it can make them a better person, and the way it can make the world a better place. You can’t directly motivate someone, but you can set conditions under which people of different attributes will become motivated.”

Exactly so – it’s about creating conditions, not about telling or controlling. It’s about making and supporting a space (physical, virtual, social, conceptual, organizational, temporal, curricular, etc) that learners both belong to and own.

Hacking Our Brains: Motivating Others By Snatching Back Rewards

Posted , updated on

Ingenious approach to extrinsic motivation – give something, then use the threat of taking it away to ‘motivate’ people to do what you want them to do. It’s an old idea, but one that has not seen as much use as you would expect in things like student grading or occupational performance assessments. Though tied up in language of the endowment effect, the essence of this method is punishment rather than reward, and we tend to be more punishment-averse than reward-seeking, so it works ‘better’. It’s still rampant behaviourism, presented in a cognitivist wrapper to make it look shinier. 

As with all forms of extrinsic motivation, this does two things, both inimical to learning. Firstly, it leads to a focus on avoiding the punishment, rather than on the pleasure of the learning activity itself. I don’t see this as a great leap forward from rewarding with grades in a learning context – it just makes it even more extrinsic and even more likely to destroy any intrinsic motivation a learner might have had in the first place so that, once punishment has been avoided, the value of the activity itself is diminished and, mostly, the things that make it useful are forgotten. Secondly, it is an even worse assertion of power than a reward. Again, I don’t see this as having any meaningful value in a learning context. It teaches greater compliance, not the topic at hand. That’s a bad lesson, unless you think that education is preparation for life in which you should be a compliant tool that reluctantly does the bidding of those in power through fear of punishment. A society organized that way is not the kind of society I want to live in. Surely we have grown out of this? If not, surely we should?

The notion that people need to be forced to comply in order to learn what we want to teach them is barbaric, distasteful and, ultimately, deeply counter-productive. Countless generations of learners have had their love of learning viciously attacked by such attitudes, and have learned with less efficiency, less depth, and less value to society as a result. It’s a systemic failure on an unbelievably massive scale, embedded so deeply in our educational systems we hardly even notice it any more. Done to one person it is bad enough but, done systematically at a worldwide scale, to ever younger generations of children, it hampers the intelligence and compassion of our species in ways that cut deep and leave us bleeding. Despite this, most of us still manage to come out of this without all of our innate love of learning completely destroyed. Our intrinsic motivation can be a powerful counter-force, just occasionally what we are taught aligns well enough with what we want and need to learn, we discover other ways and things to learn that are meaningful and not imposed upon us, and there are quite a lot of great teachers out there that manage to enthuse and inspire despite the odds stacked against them. Few if any of us survive unscathed, though most of us get something useful here and there despite the obstacles. But we could be so much more.

Half an Hour: The Study, and Other Stuff

Posted , updated on

This is the latest in a fascinating ongoing argument between George Siemens and Stephen Downes over the value, reliability and focus of Preparing for the Digital University, a report created by George, Dragan Gasevic, Shane Dawson and many others on the current state of research and practice in (mainly) online and distance learning. Because I am quoted in Stephen’s post, and in George’s post to which it is a response, as agreeing with Stephen, I’d like to clarify just what I agree with.

Where I disagree with Stephen is that I do think it is a good report that pulls together a lot of good research as well as other sources to provide a rich and informative picture of what universities have been doing in the field of online and distance learning, and how they got there. I think its audience is mainly not seasoned edtech researchers, though there is a lot of valuable synthesis and analysis in it that those of us in the field can and will certainly use. I see it as a strength that it does not just limit itself to ‘reliable’ research (whatever that may be – I’ve seldom found an unequivocal example of that elusive beast) and I am quite happy with the range and depth of the sources it uses. This is an expert summary and analysis by some of the top experts in the field who know whereof they speak. Of course it misses some things and over-emphasizes others, but that is the nature of the animal and I think it does a very good job of remaining broad, informative and clear.

I think Stephen and I are in rough agreement, though, in observing the boundary that the report does not try too hard to cross: the challenge that some of the research presents to the very notion of the university as we now know it and, to a lesser extent, the under-representation of ideas and research that relate to that. The latter point is a tricky systemic problem because, on the whole, the majority of work and writing in that space is under-represented in literature that, because it tends to come from universities, tends to focus on universities. As this report is about universities, it is quite reasonable that this is the body of literature it uses.

The relative lack of beyond-the-institution thinking is, I believe, a concern for Stephen but, for me, it’s just something that, if I were writing it, I would want to add more of. It seems to me that this report will have most value in providing information for policy makers, managers of institutions, and those who are beginning to discover the field. It will open some eyes, help people to avoid old mistakes, and open up some important discussions. But, thanks to the intentional focus on the university and how we got to now, the structures, processes and measures are mostly rooted in an assumption that the university as we know it can and should persist. The discussion that emerges will inevitably tend to focus on how digital technologies can be used to do what we already do in (from a birds-eye perspective) only slightly different ways. In doing so, it may blind participants to the very real threats to their whole way of life as well as opportunities that are worth grasping. This may not be the best idea but it is not a weakness in the report as such – it is, after all, doing exactly what it says on the box. In fact, it is to its credit that it does address some approaches and tools that are transformative. 

I agree with George (and with Stephen’s hopes) that universities are and will continue to be really important institutions that can and should offer great value to our societies for a long time to come. We would invent them very differently, or maybe not invent anything like them at all, if we started afresh, knowing what we now know. The reality is, however, that this is what we have and it has enormous momentum that is not going to stop any time soon so, if we are to make the best use of it, we should both understand and make improvements to it. This report is a solid foundation for that. There are some risks that it might, without further reflection, lead to ‘improvement’ of the wrong things – those that are counter-productive to the goals of increasing knowledge and learning in the world – and so further ensconce harmful practices. My pet hobby horses include courses, grades, and the unholy linking of learning and accreditation, for instance.  But there are other huge problems like the trend to systemic exclusion of disadvantaged people, the treatment of students as customers and the unnatural separation of disciplines and fields. Stephen mentions more. With that in mind, it would be useful to think a bit further about ways that the foundations of the university like teaching, accreditation, community, knowledge production, knowledge dissemination, being a knowledge repository, a source of expertise and so on are being not-too-subtly eroded by things that are enabled by the net, as well as to further critique the embedded patterns, limitations, biases, and blind-spots that make those foundations brittle and liable to crack or crumble.

The basis for that is all there in this report but, on reflection, I think the discussion of those issues is something for a further report as it demands a different level and kind of analysis. I am not at all sure that the Gates Foundation would want to fund such a thing, but it should. Actually, maybe that line of thinking is a bit too narrow. After all, the exchange between George and Stephen, as well as contributions by others (e.g. George Veletsianos) is already, and self-referentially, doing much the same job such a report might do, and maybe doing it better. The learning dialogue and knowledge creation that is occurring through this distributed conversation is as rich as the report itself and, in its own way, at least as valuable. If the report had not been written then that dialogue might not have occurred, so it is a good anchor, but it is part of a richer knowledge network. And that’s exactly the point: technologies like social media are deeply subversive because they enable us do some of the job that universities traditionally do without requiring a university as a necessary intermediary, with all the limitations and exclusions that implies. The patterns, technologies, economic models, checks and balances are not there yet to replace all of a university’s functions – we have much research to do and many inventions yet to invent, and I am very aware that it is only because of the university that I for one am able to participate in this – but the change is already happening, and it is quite profound.
