Teens In The UK Say Facebook Is Dead – Business Insider

This story has been carried in numerous news outlets over the past few days, most with more hype than this one. 

The hype is a little premature: Facebook is not dead yet, though it is very interesting that it is no longer the network of choice amongst younger people, not only in the UK, and has not been for most of the past year. Though a billion or more users will take a while to leave, the ugliest company in social media will need to do something amazing really soon if it is to survive. If it does go under then it might happen surprisingly rapidly, thanks to the inverse of Metcalfe’s Law, especially as Facebook is already suffocating under its own flab. It is the biggest we have ever seen but it is certainly not too big to die and, once the exodus gains momentum, could happen in months rather than years. Like MySpace, Hi5 and others that have fallen out of favour, it will likely collapse in a big way but won’t totally vanish, especially given some sensible investments in things like Instagram that do make a lot of sense. Is this a bad thing? While mostly evil in its business practices, it has made some significant contributions to open source projects, but not enough to compensate for the harm it has done to the Internet in general: I won’t be sorry to see it go. It doesn’t need to be replaced. That’s not how things work any more.

Facebook Is A Fundamentally Broken Product That Is Collapsing Under Its Own Weight

An article from Business Insider reporting on Benedict Evans’s compelling analysis of Facebook’s big challenge. Essentially, there is too much data, and Facebook’s algorithms cannot cope. In fact, algorithms are part of the problem…

today, you could post that you’re getting married, but only half of your friends might see that posting because of the News Feeds’ algorithms.”

And algorithms are not the solution…

 “If you have 1,500 emails coming in every day, you wouldn’t say, ‘I need better algorithms.'”

So what next?

By this time next year we could have 3,000 posts, links, videos, status updates, etc., all flowing through the News Feed. It’s a struggle to sort through 1,500; how will Facebook deal with sorting through 3,000?”

Basically Facebook is broken and, unless its henchpeople and minions can come up with something radically new, it is not going to be fixed and it will just get worse. Sure, Facebook as a central service is not going away any time soon (probably – Metcalfe’s Law works in reverse too, so I’d not want to place any bets on that) but it doesn’t work as a social network any more, precisely because of the avaricious, amoral, single-minded network-building design that made it what it is today. I think it did a very sensible thing in buying, but not fully integrating, Instagram, because it can only grow now by moving into other ecosystems and dissociating the core from the satellites. It probably needs to go on quite a big spending spree now.

Seeing Facebook begin to fail, at least in its core, pleases me because it rose to success by cynical exploitation. It went places other social networking systems that predated it, as well as most that have come since, feared or had no inclination to go. You can’t have too many predators or parasites of one kind in an ecosystem otherwise the whole system falls apart. Or, to look at it another way, Facebook got too fat eating its own users, and now it can’t digest them any more. Either way, we’re much better off without it.

Boston Study: What Higher Standardized Test Scores Don’t Mean

Interesting report and interview on the relationship between test scores of ‘crystallized skills’ (what schools teach) and ‘fluid intelligence’ (basically, the ability to think). Of course, there is none. Futhermore, teaching makes almost no contribution to logical thinking and problem solving in novel situations, at least for the 1400 eighth graders being studied.

where a school accounted for approximately 1/3 of the variation in state test scores, they accounted for very near zero of the variation on these fluid cognitive skill measures.”

This is hardly surprising in a world where the success of teaching is measured by standardized tests, and teaching is focused on achieving good results in those tests. The researchers are right to observe that crystallized skills are important, so this is not necessarily all bad news: schools appear to have some effect. However, I strongly suspect this is a short-term effect (as long as is needed to pass the test) and much less than it could be due to the extrinsic motivation designed into the system which actively degrades the students’  intrinsic motivation to learn. Whether or not that’s true, it’s a terrible indictment of an educational system that it affords no opportunities to develop the thinking skills that matter more. These skills are not measured in the standardized tests nor could they be measured in that way without destroying what they seek to observe. This doesn’t mean that we need better tests. We need better education.

Top UK headteacher: Michael Gove is 'pressing the rewind button'

An article from the Guardian that makes me glad my kids have already gone through the UK school system. The pigeon-brained fool in charge of UK education right now, Michael Gove, is doing his level best to set school education in that country back a hundred years, ignorantly or wilfully ignoring every shred of educational research over the past century. He is living proof that an expensive education doesn’t automatically lead to an educated person and might even lead to the reverse: allegedly, he was a somewhat intelligent child, at least before he went to an independent school. Surprising. Thank heavens for people like Tricia Kelleher, the main subject of this article, whose common-sense critique rings true. I particularly like her complementary observations:

“If Michael Gove is saying we should just value what is in Pisa, then we might as well just collapse the curriculum and teach what will come top.”

and

“My worry is we are now going to be driven towards Pisa because Pisa becomes the next altar we worship at. But it is really a cul-de-sac in learning terms.”

Well said.

It makes me wonder about why we allow elected representatives with much less than no knowledge of education to run/ruin our educational systems. There must be some appeal among a significant number of people in the lunatic measures of success that they latch onto but that actually guarantee failure, such as PISA, standardized testing and the deliberate teaching of things that alienate children, along with counter-productivity initiatives that seek efficiency but that liquidize the baby with the bathwater. I’m guessing that these ideas might resonate with and spring from some of those who were brought up under the long-discredited behaviourist regime that blighted the mid-twentieth century and that still refuses to die in some places, even among educators. Few of us are very rational beings and we suffer, amongst many other things, from irrational primacy biases, choice-supportive biases, confirmation biases, irrational escalation and endowment effects that together lead us to believe that what was done to us was the right way to do things, no matter how much the available evidence proves that it was not.  Unfortunately, those who were damaged by behaviourist teaching approaches have been taught one of the best ways not to learn so, notwithstanding a good many who rise above it and/or who learned to learn in other ways, this may be a vicious cycle that is doomed to repeat itself for a while longer.

Who's Cheating Whom?

I love Alfie Kohn – his writing is consistently clear, constructive and filled with sound arguments based on bulletproof research that continue to surprise even though the conclusions are completely obvious to anyone who spends a moment thinking about it. In this essay he shows how we, the teachers and our institutions, are the principle cause of cheating, creating elaborate and demotivating gotchas and systems designed to make cheating rewarding and, perhaps, inevitable. As a result, we are cheating students out of the joy learning. We are teaching them not to learn. Full of useful insights and simple but not simplistic solutions.

Donald Clark Plan B: When Big Data goes bad: 6 epic fails

Donald once again in brilliant form cracking open a bunch of academic memes that still pervade the education system and have way too much influence on those that fund it. Especially good on challenging the awful data underlying standardization and comparisons like university league tables and PISA scores on which governments and journalists thrive.

Being-taught habits vs learning styles

In case the news has not got through to anyone yet, research into learning styles is pointless. The research that proves this is legion but, for instance, see (for just a tiny sample of the copious and damning evidence):

Riener, C., & Willingham, D. (2010). The Myth of Learning Styles. Change: The Magazine of Higher Learning Change: The Magazine of Higher Learning, 42(5), 32-35. doi:doi: 10.1080/00091383.2010.503139

Derribo, M. H., & Howard, K. (2007). Advice about the use of learning styles: A major myth in education. Journal of college reading and learning, 37, 2.

Coffield, F., Moseley, D., Hall, E., & Ecclestone, K. (2004). Learning styles and pedagogy in post-16 learning: A systematic and critical review. 041543).

No one denies that it is possible to classify people in all sorts of ways with regards to things that might affect how they learn, nor that everyone is different, nor that there are some similarities and commonalities between how people prefer to or habitually go about learning. When these elaborately constructed theories claim no more than that people are different in interesting and sometimes identifiably consistent ways, then I have little difficult accepting them in principle, though it’s always worth observing that there are well over 100 of these theories and they cannot all be right. There is typically almost nothing in any of them that could prove them wrong either. This is a hallmark of pseudo-science and should set our critical sensors on full alert. The problem comes when the acolytes of whatever nonsense model is their preferred flavour try to take the next step and tell us that this means we should teach people in particular ways to match their particular learning styles. There is absolutelly no plausible evidence that knowing someone’s learning style, however it is measured, should have any influence whatsoever on how we should teach them, apart from the obvious requirement that we should cater for diversity and provide multiple paths to success. None. This is despite many decades spent trying to prove that it makes a difference. It doesn’t.

It is consequently a continual source of amazement to me when people pipe up in conversations to say that we should consider student learning styles when designing courses and learning activities. Balderdash. There is a weak case to be made that, like astrology (exactly like astrology), such theories serve a useful purpose of encouraging people to reflect on what they do and how they behave. They remind teachers to consider the possibility that there might be more than one way to learn something and so they are more likely to produce useful learning experiences that cater for diverse needs, to try different things and build flexibility into their teaching. Great – I have no objection to that at all, it’s what we should be aiming for. But it would be a lot more efficient to simply remind people of that simple and obvious fact rather than to sink vast sums of money and human resources into perpetuating these foolish myths. And there is a darker side to this. If we tell people that they are (just a random choice) ‘visual’, or  ‘sensing’ or ‘intuitive’ or ‘sequential’ learners then they will inevitably be discouraged from taking different approaches. If we teach them in a way that we think fits a mythical need, we do not teach them in other ways. This is harmful. It is designed to put learners in a filter bubble. The worst of it is that learners then start to believe it themselves and ignore or undervalue other ways of learning.

Being-taught habits

The occasion for this rant came up in a meeting yesterday, where it was revealed that a surprising number of our students describe their learning style (by which they actually mean their learning preference) to be to listen to a video lecture. I’m not sure where to begin with that. I would have been flabbergasted had I not heard similar things before. Even learning style believers would have trouble with that one. One of the main things that is worth noting, however, is that this is actually a description not of a learning preference but of a ‘being-taught habit’. Not as catchy, but that’s what it is.

I have spent much of my teaching career not so much teaching as unteaching: trying to break the appalling habits that our institutional education systems beat into us until we come to believe that the way we are being taught is actually a good way to learn. This is seldom the case – on the whole, educational systems have to achieve a compromise between cost-efficiency and effective teaching –  but, luckily, people are often smart enough to learn despite poor teaching systems. Indeed, sometimes, people learn because of poor teaching systems, inasmuch as (if they are interested and have not had the passion sucked out of them) they have to find alternative ways to learn, and so become more motivated and more experienced in the process of learning itself. Indeed, problem-based and enquiry-based techniques (which are in principle a good idea) sometimes intentionally make use of that kind of dynamic, albeit usually with a design that supports it and offers help and guidance where needed.

If nothing else, one of the primary functions of an educational system should be to enable people to become self-directed, capable lifelong learners. Learning the stuff itself and gaining competence in a subject area or skill in doing something is part of that – we need foundations on which to build. But it is at least as much about learning ways of learning. There are many many ways to learn, and different ways work better for different people learning different things. We need to be able to choose from a good toolkit and use approaches that work for the job in hand, not that match the demands of some pseudo-scientific claptrap.

Rant over.

 

Endnote (die die die)

I’m generally liking both the price and the performance of Mavericks on my relatively new-ish Mac, although there are some compatibility issues here and there, including with some of my most used software like MailTags, and although it won’t work on my old but still serviceable and well-loved first-generation Intel Mac.

But one incompatibility is really upsetting me, especially as I have deadlines to meet – EndNote X5. Thomson Reuters have no intention of fixing this and suggest upgrading to X7, which will get an update ‘in the next few weeks’. I have been irritated by EndNote too many times over the past few years, with perfectly servicable versions failing each time a new version of Word (another hateful piece of software) comes out and requiring costly updates, despite adding absolutely no new functionality of any value at all for over 10 years. Not to mention Thomson’s evil and cynical attack on the open-source Zotero. But this is ridiculous. X5 came out in late 2011, I bought it in 2012, and there have been two pointless and expensive updates since then, neither of which is anything more than a minor point-release. I reluctantly paid for a copy of X5 because, despite not wanting to use it and having perfectly decent free and open alternatives like Zotero and the pre-acquisition version of Mendeley, I work with people that do use it and it makes life easier to share the same reference manager. Now I give up. It has long been the case that EndNote is bloated, buggy and overpriced. Thomson Reuters are able to get away with it because of lock-in and path dependencies. When it was one of only a handful of options it was about as good as it got, so lots of people used it and it spread like a disease for compatibility reasons. I don’t care how difficult it makes it to work with collaborators around the world, or the effort involved in learning new quirks of new reference managers, I will no longer support Thomson’s greed. Their lack of interest in their locked-in customers as anything other than cash cows is more appalling than their ugly software. On the bright side, it will hopefully reduce my dependency on MS-Word (same collaboration issues) too.

I’m defaulting to Zotero but, if anyone has any alternative suggestions (I don’t mind paying if it is worth the money), do pass them on!

Pedagogy – Scrap exams to create schools of the future – news – TES

A report on the findings of this year’s Equinox Summit. Amongst the more interesting:

the summit’s conclusion was that, in less than 20 years, “knowing facts will have little value”, meaning that schools will have to scrap conventional examinations and grades and replace them with more “qualitative assessment”. This would measure a student’s all-round ability, rather than testing their knowledge in a particular subject.”

A lot of other sound and common-sense ideas are reported on here. All good stuff.

China Wholesale – Wholesale Electronics – Dropship From China

Thanks to my friend Richard for pointing me to this great site for total geeks. Electronic toys galore, at knockdown prices, direct from China. Important proviso – almost all look pretty awful, but the site is honest about their failings and ridiculously rich in information about them, so it is easy to decide not to buy things. But who needs Apple, Samsung, or Sony when you can get a no-name budget dual SIM Android phone for $70? Or any number of watch-phones, projectors, remote controlled doodahs and accessories to fit any need? Well, me. But I like browsing this site.
