Exemplar of successful implementation of tech in schools

Not often you see schools having resolved the ‘technology’ issue. It is usually a contentious issue, often tribal, defensive, even hostile. Despite the endless claims on workload, the refusal to do what every other area of human endeavour does, use technology to reduce it, education often seems to wilfully avoid the issue. Schools have, in the past, been quite independent, creating their own websites, buying and building their own technology, reducing much of it to a cottage industry. It was impressive to find a school network that took technology as seriously as Curro, in South Africa. They had invited me to give a keynote on AI for Learning, based on my book and experience but I hung around as the teacher sessions were so damn good. This is what I learnt, as I think it is a recipe for success.

Centralised service

Curro technology was a centralised service that provided CPD for all teachers, as well as procuring and implementing ALL technology across the entire network of schools. This is NOT simply centralised procurement, it is a group with the deep expertise needed to tackle the change management, training, trials and implementation of a range of activities. They had already implemented a wide range of technologies across the network, accessible through a single point of entry. This, I think is a necessary condition for success, single door, single sign-in. Everything from administration to advanced AI and adaptive learning systems were distributed from this point. Teachers, in particular, appreciated the simplicity of this one-stop-shop approach. It was clear that the service also had real and trusted expertise from which the whole school could draw, rather than distributing responsibility out to all teachers.

Ecosystem of technology

There was a real sense of technology as a force for good in teaching and learning. With champions out in the schools, supported by expertise at the centre, they understood the balance between innovation and implementation. This allows experimentation and constructive feedback. I got none of the tired scepticism I’ve seen elsewhere. Rather than plump for one system, they have built an ecosystem of technologies accepted by everyone. Careful choices, careful implementation and the sense that different tech meets different needs.

Emphasis on CPD

Webinars and other training is distributed, a term in advance, with practical training in hte technology, news on what’s new and other relevant services for teachers. It is clearly a dynamic service designed to bring teachers with them in the change management process. I was giving a talk as part of that process. The day’s activities were under the banner of ‘Imagining 2022’. It’s hard enough to Imagine what any year will bring these days but it was clear that this was a learning organisation, willing to learn from their mistakes and make the effort to plan forward. It was CPD organised by teachers for teachers and not scared of introducing outside ideas and speakers. There was no sense of being a protected, inward-looking process. You got that sense of CPD being in the hands of the teachers themselves, not something done TO teachers.

Content curation

The teachers were full of praise for the provision of content that they could use themselves or for students. There was no sense of the schools hanging on to the idea that ALL content has to be created and delivered internally by the existing teachers. So what of it wasn’t invented here. It was refreshing to find a sense of openness to curated content from outside sources.

Adaptive learning

This was the big surprise. There were glowing testimonials from teachers about the power of adaptive learning, using AI, to personalise learning for students. It was described as a ‘gamechanger’ by the teacher who presented, with clear targeting, so that efficient and relevant, individual interventions could be made for students. It was clear that they knew why they wanted this technology, had implemented it well and were using teacher feedback to spread the word internally.


Content, slides and short videos, along with digital worksheets, were used in class with regular assessments. A big win was saving time on marking and correction, which was automated and done instantly, even alternative question provision. This, I feel, is an argument that is massively underappreciated in schools. Diagnostic questions, provided by the system were found to be particularly useful, for identifying individual learners’ strengths and weaknesses. This meant that teachers didn’t have to wait for an assessment before making an intervention. There was also openness to including parents in the process, using the tech to allow access to their progress, lessening the need for teachers to respond to parent requests. Learners at home can also be held accountable for work in class or at home in realtime. This use of technology to extend teaching and learning was exactly what I had presented in my Keynote, using Artificial Intelligence as ‘Augmented’ Intelligence.

Conclusion

Far from being reactive to innovation they were on the front foot, seeking out the best of breed technologies. By creating a separate entity that centralised these efforts they could keep delivery safe and simple, as well as think about how to bring staff with them. The fact that I was brought in, someone 5,500 miles away, to give a talk, was a testament to their ambition and openness. I learnt more from them as they did from me. That’s as it should be.

Part 3: Metaverse - a look into the possible abyss

Owning a Metaverse is one thing, owning the discourse and language of the Metaverse is another. Note how we’re all now using an invented and owned Facebook brand the ‘Metaverse’ to even talk about this. I get the feeling that we’re being suckered. 

It comes from Neil Stephenson’s 1992 novel Snow Crash (which was the white noise seen on screens when the system crashes). It is an astonishing novel, where the virtual world, the Metaverse sits in an anarcho-capitalist world, owned by the Global Multimedia Protocol Group. You access it via VR, controlled by a monopoly cable television group that has replaced all telephone networks, all of this is very close to the Facebook bone.

Facebook’s land grab of the virtual world through Metaverse branding is slick PR but it stinks. It is as if just naming something makes it real. The brand alone acts as the new centre of gravity. Metaverses have been around for decades, what is different is the branding and financial commitment that Facebook have put into this. Apple is having to pay developers six-figure cash sums to retain them, such is the recruitment pull into this world.

Shift to Web 3.0

This is all part of a much bigger shift in tech, re-defining itself as Web 3.0 with an open, permissionless, decentralised world of cryptocurrencies, NFTs, blockchain and multiverses. Why? If you’re in regulatory trouble in this world, create a new one. You are then free from those authorities and constraints. 

Even better, create a system where you make money, and I literally mean ‘make’ money as cryptocurrencies. You create money, then rake in even more money, make virtual stuff, sell it - all of a sudden you have an economy, free from governments and control. That is how these brands already escape tax - they play us by creating virtual excuses. They trade online, making it difficult to pin down taxable entities such as true sales and profits, then shift to low tax regimes to literally steal revenues from the actual countries that accrue the sales and profits. They are the masters of illusion as what they deal in is illusions. This next step is to create a wholly illusory world - the Metaverse.

The libertarian roots of Silicon Valley have outgrown their teenage years. They’re now greedy adults - they want it all. Not content with grabbing all the real money they want to destroy the real and make even more money from the unreal.

People in the Metaverse

Commentary on Tech swings from utopian to dystopian, from hype to horror in a flash. But the

Metaverse could turn out to be a crime-ridden scamfest, full of fakery, rug-pulls, NFT frauds and cryptocurrency BS. The real world has plenty of crime and scams, as does the existing online world but the Metaverse may actually create worlds where this is made so much easier. No one can hear you scream in cyberspace. We may all have our digital twin in the Metaverse but there will be swarms of Jekyll and Hyde twins to deal with.

Objects in the Metaverse

In The Conspiracy of Art (1996) Baudrillard trounces modern art. His book Simulacra and simulations (1981) gave him fame in the art world but this critique of that world demolished the pretence that they were at the vanguard of relevance. Art has become a set of signals, everywhere and nowhere, part of a consumerist nexus with its careers, commerce and tawdry fame. For him it has become a mediocre game of high-end, consumerist and status exchange. He would have been writing about NFTs (Non-Fungible Tokens) if he were alive today, the creation of digital entities, largely as investment assets. They are already being seen and marketed as assets within the Metaverse.

Nike has acquired a virtual shoe company, RTFKT, who also make NFTs. Let that sink in. They want to sell virtual shoes for virtual people in virtual worlds. Other high-end brands will buy into that virtual economy. That should make us think.

What should also make us think and worry is the strange tale of the ‘Evil Ape’ NFT developer who disappeared after deleting his Twitter account and website, with $2.7 million of investors’ cash. Evolved Apes was a supposed Multiverse full of NFT apes who were to fight each other for survival. The Multiverse and game never appeared. The cash, a cryptocurrency called Ether, disappeared. You’d think the foolish investors would have learnt their lesson but they’re carrying on with Fight Back Apes, fighting the Evil Ape. The whole episode contains all the signs you need on this combination of NFTs and cryptocurrencies in a supposed Multiverse. It will be a dark place, attracting every scammer on the planet.

Places in the Metaverse

Forget simple shoes and images, land and properties are already being sold in Metaverses. When Snoop Dogg developed his Snoopverse, someone bought a property in his virtual world for almost $500,000. “I'm always on the lookout for new ways of connecting with fans and what we've created in The Sandbox is the future of virtual hangouts, NFT drops, and exclusive concerts.” Snoops virtual house is modeled on his real house and you can buy expensive  passes to get access. Platforms are already there, such as Sandbox and Decentraland, with Sandbox already clocking up a $4.3 million sale for a plot of land. Investors and major brands are already buying into the Sandbox project. The role that celebrities and influencers play in this movement will be interesting.

Conclusion

This may turn into a new gold rush, creating a wonderful new market or a form of tulip mania where many lose their shirts. Who knows? What makes this different from previous Multiverses, such as Second Life, is that the underlying technologies, with cryptocurrencies, an already existing NFT market and a ubiquitous, high-bandwidth, cloud-based internet, make it a much more sophisticated world. As we spend more time in such places, we may well be willing to spend money on the places we inhabit. This is the economy of experiences, not physical assets. At the moment it looks as though assets, rather than experiences are its main inhabitants.

Part 1: Philosopher of the Multiverse - Baudrillard

I have expressed scepticism around the relevance of Foucault, Lyotard and Derrida. Oft-quoted and rarely read, they are plucked from the Postmodern Hall of Fame and used by many to fashionably deanchor us from people in the past and present. But there is one French philosopher I have read all my life, who is very much an outlier - Jean Baudrillard (1929 - 2007). He has proved far more relevant as a philosopher, cultural theorist and prophet. Following on from my last piece on the Multiverse(s)...

How Metaverses develop

Neo, in The Matrix, carries a copy of Baudrillard's Simulacra and Simulations (1981) to make the point that the film is grounded in and a commentary on simulations. 



But The Matrix scene with its old-school computer discs inside the book seems rather dated now. The Multiverse(s) is a far more significant move towards the Baudrillian world of what he called hyperreality. As face-to-face and print media moved towards film and television, then online worlds, Baudrillard redefined media in terms of simulcra, or created entities that are no longer just representations but created realities in themselves, de-anchored from reality. These are not just digital media but worlds divorced from reality. He is, the philosopher of virtual reality, the man who envisioned and defined the Metaverse in its infancy, knowing what was to come.

Rather than seeing the world in terms of the old binary oppositions of appearance and reality, subject and object, oppressors and oppressed, he sees us as increasingly being in a world of Simulacra and simulations (1981) – ads, TV news and soap operas. With the Metaverse, we are literally moving into those worlds, inhabiting them, creating new economic models and economies within them.

He maps out the way in which this develops. Metaverses start first to reflect a reality, they then mask and pervert that reality and increase the absence of that reality, then finally bear no relation to reality. There is a brilliant passage in this book on Disneyland. You will never see that place in the same light after reading this critique of the US ‘embalmed and pacified’.

Astonishingly, all of his work was written in the era of broadcast media, before the internet. Now that his simulacra are being realised in computer games, social media, virtual reality, artificial intelligence and now Metaverses, he is more relevant than ever. 

Metaverses and meta-narratives

He rejects what other Postmodernists called meta-narratives, the Marxist and Freudian ideas of the free agent. But where he differs is in positing an alternative, replacing it in Consumer Society (1970) with a more complex agent as consumer and consumption,  not production, as the new locus of economic activity. The areas of economic activity are now simulated environments in the real world, in malls, with their perpetual springtime and shopping. We even buy these simulated ‘experiences’ even in what appears to be the physical world, such as Disneyland.

These new drivers have made us not producers but consumers, with a huge capacity for consumption. Credit literally fuels this excessive consumption by making the satisfaction of these desires easy and immediate. He goes much further in The Mirror of Production (1973), where the major elements in Marxism are demolished. Turning Marxism on its head, he restatess it as a justification for the very system it claims to destroy. With its focus on labour, production and value it lacks distance from the system, working within the mechanics of production. This focuses on the free economic agent rather than that of the consuming agent.

Baudrillard is also the philosopher of ‘consumerism’ which he thinks is now a refutation of ‘communism’. Rejecting the economic explanations of traditional Marxism, the actual world is now a complex nexus of consumerism, communications and commodities. Cryptocurrencies, NFTs, tradable digital entities in games worlds free float beyond Marxist materialism. People are no longer economic agents with a process of production, they are agents who consume and occupy hyperreal worlds. The fact that one of the largest, most valuable and globally pervasive companies on the planet has adopted this as their brand and goal confirms his view that physical production is no longer the essence of capitalism.

Metaverse and history

In The Gulf War Did Not Exist (1991) he shocked many, claiming that the war, as re-realised through media, had created a reality separate from the actual war. His deeper meaning was that when events become dislocated in this manner, history itself collapses through dilution. It moves us beyond an ‘event’ based culture to a non-historical state. Being stuck in the ever-present spectacle, we forget the past.

It is not just that such wars are now filmed, tweeted and YouTubed, many are almost immediately turned into movies and computer games. Dozens of movies now exist and I know of at least 18 computer games based entirely on, or containing, Gulf War events. Revolutions are no longer televised, they’re gamified.With 9/11 we saw this happen with even more intensity and reach, where the two perspectives of the event result in the clash of two separate and global worldviews.

Baudrillard’s position on all of this was brave and honest. He thought that this was almost inevitable. That we as a species will drown ourselves in our own simulacra, its all-consuming nature will smother and consume us. His only reaction was Nietzschean - silence. Baudrillard really (or unreally) is the philosopher of the age of Multiverses.

Part 2: 20 reasons why the Metaverse may not work out as we think it will

Watching Nick Clegg being interviewed by Horaah Hendry of the FT was embarrassing. Two old men with teenage avatars talking to each other was creepy enough but when they back-slapped each other about being anti-Establishment, it all got a bit arse about facebook. This was facebook PR puff, not journalism. The awkward, missed fist-bump and Clegg holding and drinking an invisible coffee cup, all added to the Pythonesque weirdness. This nonsense aside, we do need to ask some serious questions about this proposition - the Metaverse.

Baudrillard, the prophet of such simulated worlds and their effects on humanity, sees such worlds as being more than extensions of humanity. They capture our attention and hold us hostage. As the world has become de-anchored as God's creation, we began to build our own worlds. It is not yet clear where all of this is going, or more accurately, taking us.

I have been involved with VR for some years, had both the early Oculus kits, written tons about virtual worlds and demonstrated it to many hundreds of people all over the world, including Africa. I have a whole chapter on this in my book Learning Experience Design (2021). These worlds are not new. We know a lot about them and can start to speculate about their future. 

1. Facebook’s landgrab

One worry that most people should have is that this is Facebook. Rebranding the whole company as Metaverse, or Meta, is a huge leap but the Metaverse brand is just flying a marketing kite. It is not really a rebrand - we, and they, still call it Facebook. What we need to question is their move towards total ownership of such virtual worlds. By owning the world, you own everything; the who, what, where, when and how. As a landgrab on the internet, it needs to be treated with due suspicion.

2. Data on everything

Then there’s the data collected within the Metaverse. Facebook want to do a Microsoft and own the OS for virtual worlds by market dominance. At the moment data is distributed, do we really want a centralised place where data can be harvested, not only social data, what is said, but also physical, behavioural data? The opportunities fro extreme forms of surveillance are obvious, so I think not.

3. Metaverse as an economy

Most metaverses, even Second Life, but mostly large-scale games, create worlds in which people want to buy and sell virtual stuff. That's fine on a small scale. When you have a world that is the size of a small, even large, country, you have an economy. But economies are regulated. Do we want facebook to be a regulated economy, like a country? There are already serious concerns about Facebook’s role as a supranational force. One can see the time when such virtual worlds have the status of a country but not for now, and not ones where Billionaires are kings, no matter how benign the PR says they are.

4. Metaverse crypto

Notice how Facebook dabbled in cryptocurrency recently? In 2019 it created Libra, rebranded in 2020 as Diem. This created such a backlash that it has all but disappeared. That doesn’t mean it has disappeared. Facebook as a central bank controlling a cryptocurrency is a frightening thought. Remember, Facebook is not creating a Metaverse as a charitable act, they want to make money... lots of it. Allowing them to create a global virtual world with a virtual cryptocurrency and economy is being touted. This is truly frightening.

5. 2D to 3D problem

3D movies and 3D TV bombed. Sure we like 3D but desirable experiences are not all about 3D fidelity. Even stereo is no longer a big deal in listening to music. Media rich is not mind rich. We love a good podcast precisely because it is a stripped down, single media experience. It feels intimate, like being in that conversation. Turns out that for entertainment and much else, we like just enough to do the job well for immersion (big 2D TV) and no more. The Metaverse may be piling on the pixels but it is not clear that this is what consumers want.

6. Communications

The Metaverse has problems when it comes to communications. It is not so much the high fidelity expectations of the avatars but the communications within a group. It is difficult to get turn taking and the real dynamics of a real meeting going in such environments, especially when they are in a 2D representation. We have two ears, two eyes and a brain that has evolved to monitor around us. Our ears are the shape they are, with folds, as a form of sterescopic radar for listening to others around us. Our eyes are stereoscopic and on the top of our swivelling necks and bodies. Take any of that away and you have a problem. Interestingly Zoom solves that by taking a 3D world and tiling it in 2D. The Metaverse may therefore have a worse group dynamic than Zoom, a lot worse.

7. Turn taking

In a fascinating piece of research by Carnegie Mellon, it turns out that turn taking and problem solving went better when learners turned OFF their video cameras. It would appear that not seeing others in a group is sometimes a lot better than full visibility, as one can focus on the task, not the people.

8. Appearances matter

The Carnegie Mellon study surprised a lot of people who had turned to teaching online during Covid, where the general advice was to keep students’ webcams ON. Counterintuitive though this may be, it seems that students are concerned about how they and their home environments look online. This says something about being careful about true needs in full-blown online environments. That's why most existing Metaverses are chocked full of bizarre avatars.

9. Avatar narcissism

In most virtual worlds, weird avatars are the norm, as people don’t really want to show their true age, weight and looks online. It is all colour, costumes, animals features, weirdness and cartoon fun. How people represent themselves online is far from what they look like in the real world. Will we have a parallel world where people are perennially young, good looking and thin or look like oddballs to mask their ordinariness? It promotes exaggeration of social norms around what one should look like on one hand and freakshows on the other. 

10. Meetings

In a sense, Zoom meetings have accelerated the experience and demand for virtual worlds. Yet there are real doubts about the Metaverse as meetings' technology. Meetings need to be real. We have meetings because we want to have real discussion and make decisions. Is this helped by another layer of representation - avatars? Maybe not. We want to hear real voices and see real faces. The key is not actually the tech but how the meetings are set up and run. They need a good Chair, clear agenda and proper turn taking, along with a movement towards decisions and actions. Having a cartoon, avatar layer may not help one bit. In fact, it may distance you from, or smother, the event.

11. Overstimulation

A surprising finding in VR research was its of lack of efficacy in learning. This is partly to do with the poor design of learning experiences and the focus on creating worlds, not actual learning experiences. But there are lessons to be learnt. Overstimutaion is clearly a problem. People are overwhelmed, and get a sort of stage fright or wonderment in fully immersive online environments. They also get obsessed with detail. This can hinder, rather than help with other tasks, such as efficient meetings and learning. There seems to be a form of uncanny valley effect going on here, where the technology captivates but doesn't relax you.

12. Playworlds

What happens when you build such worlds. Turns out most people muck about a lot. They have fun. It is not as conducive to serious endeavours as you would think, such as collaborative brainstorming and design, even meetings. In fact, it is often a bit anarchic. In VR open worlds, you get people donning full body suits and doing gymnastic moves (and more). It’s showtime! That's why most Metaverses are actually in the games world, something that seems to have passed everyone (apart from gamers) by.

13. Policing

I had a female avatar in Second Life and used to recommend this as the best form of sexual harrassent training you’ll ever receive as a man. It was relentless. There is a real problem in policing this sort of behaviour in open worlds. It is not like the real world where norms are accepted, rules and laws implemented and agreed. It is all a bit Wild West.

14. Fakery

Fakery is the norm in terms of appearance but there is also the problem of fraud and fakery on scale when such a world becomes a phishing ground for scammers and scams. It is bad enough with email and the simple telephone without full-on people talking, charming and defrauding you into doing things that are harmful. The potential for bad actors doing bad stuff is immense.

15. VR shutout

Note how we go full screen when screensharing, that makes sense in terms of focus. There is nothing worse than using 3D VR then seeing 2D video and PowerPoint inside that environment. The problem with VR is that it stops you from using keyboards, taking notes by pen and generally seeing and dealing with the real world. VR is a new medium and not a gadget, yet has not taken off as a mass medium. Even when untethered, it is still largely a niche gamed device. That tells us something.

16. Tech not invisible

Good technology is increasingly invisible. The Metaverse, especially if it involves headsets, makes the technology incredibly tangible, visceral and obvious. It may be that the invisible tech, powered by AI and data, such as IoT, voice assistants and AI as the new UI, will win out and not Metaverses. People want solutions not clumsy tech and the Metaverse is all too visible and clumsy.

17. 90:9:1  consume:comment:create

Most people online are lurkers who consume (90%), a small percentage comment (9%) and 1% create. You can play around with these figures but you get the point. The Metaverse may be just another playground for the 1% of extroverts and narcissists. Most people are reluctant to expose themselves and engage with strangers in such environments, so we may be looking at yet another niche world.

18. Build

Another problem associated with the 90:9:1 problem is who will build these worlds? Fine in Minecraft but the idea that adults will be able to handle the tools and have the time and inclination to do this is ambitious, if not utopian. It is not just the tools, it is the skills. Giving someone a copy of Word does not make them a novelist and giving someone a 3D builder does not make them an architect. Sure there may be pre-built environments. But this is a gargantuan task. 

19. Social engagement

Do people really want to engage with strangers like this, as avatars in a virtual world? It is not clear that they do. The reluctance to engage in this form of communication is interesting. Low-fidelity, social media may actually be better as there is less reveal of the self and more control of exposure. We still use texting, messaging and voice calls - a lot. Virtual worlds give immediate and total exposure that can be unsettling. People may not be as openly social as the extroverts think.

20. Breakout problem

We have a differentiation of media. While the Metaverse is being touted, we have the rise of the audio-only podcast, the inverse of the Metaverse. Philip Rosedale the chief architect of Second Life gave up on High Fidelity, a VR version of Second Life, to focus on spatial audio technology. Second Life is still a million people and a $650 million transactional environment but, as Rosedale says “it didn't break out, it didn't become a billion people. And the hope that Facebook has is that there'll be a billion people using a metaverse”. Maybe, maybe not.

Conclusion

Technology surprises and I have no doubt that Metaverse-type tech will do just that. It may be in speaking to our future or past selves, learning languages, political engagement, dating, porn - no one really knows. But of one thing I’m sure, it will happen, just happen differently from how we envisage.

Wittrock Generative learning

Merlin Wittrock (1931 - 2007) worked at the University of California and saw good learning as a generative process. In a series of papers over two decades he saw 'generative' learning as the key to creating a shift in education towards more efficient learning. 
It has its roots in Bartlett (1932) and Piaget (1926) who both saw learning as acts of construction and, for Piaget, fitting knowledge into existing schemas. But for Wittrock, generative learning theory was built on the idea of learners integrating new knowledge and skills into what they already know though generative activities, where effective teaching facilitates leavers to construct meaning from various generative experiences.

Generative theory of learning

Wittrock not only developed his generative theory of learning, he also researched its effectiveness and applied it in practice. Learners, for Wittrock, are not passive receivers of knowledge, they are active reorgansisers of knowledge, creating meaning from their own generative activities. His generative learning theory was built on the idea of learners integrating new knowledge and skills into what they already know through generative activities. Effective teaching must therefore facilitate learners to construct meaning from various generative experiences.

His model encourages learners to generate meaning and understanding from instruction through effortful, generative activities and has four major processes:

(a) attention - directing generative processes on relevant incoming material and stored knowledge

(b) motivation - willingness to invest effort to make sense of material

(c) knowledge and preconceptions - prior knowledge, experiences, and beliefs

(d) generation - sense making

For Wittrock all four have generative components, what some would describe as constructive, where the learners control and build their own models, rather than interpreting taught content. Teachers must therefore learn to lead learners towards learning by encouraging generative activities. 

Generative activities

The generation of notes in one’s own words, use of analogies and effortful activities are all generative. Summaries and analogies in reading, for example, is an effective learning strategy, Wittrock & Alesandrini (1990). 

Fiorella & Mayer (2015) recommend eight types of generative strategies:

Summarizing: Create a written or oral summary of the material 

Mapping: Create a concept map, knowledge map or matrix organizer 

Drawing: Create a drawing that depicts the text

Imagining: Imagine a drawing that depicts the text 

Self-testing: Give yourself a practice test on the material 

Self-explaining Create a written or oral explanation of the material 

Teaching: Explain the material to others 

Enacting: Move objects to act out the material

Problem solving

With Richard Mayer, Wittrock also contributed to research on problem solving in order to identify the best way to teach it, with three main findings:


  1. Domain-specific principle - teach problem as a domain specific skill not as a general skill

  2. Near transfer principle - accept that problem solving skills work across a limited range of applicability

  3. Knowledge integration principle - use guided problem-solving tasks to teach knowledge


Wittorck was heavily involved in teacher training and his generative theory was not just about what the learner did, it was also about appropriately generative teaching strategies. Problem solving was one such strategy.

Critique

Generative learning has been criticised by some as swinging the instructional pendulum too far towards discovery or exploratory learning, diminishing the role of direct instruction. Its singular focus on the generative processes, some think are partial, with other processes involved in learning.

Influence

Wittrock’s work on generative learning has not had as much influence as the topic and his work deserve. As technology has developed and social media normalised, the creation of text, images and videos have become common online, generative activities.

Education during COVID debate in Berlin


The UK Government has announced an acceleration of the booster programme, as they know a huge wave of infections is coming based on Omicron's infection rate (high). Although the variant is less lethal, when you have so many people infected, the strain on hospitals will be intense and people will die.

Yet the Government (and opposition) completely ignores the fact that schools and Universities are two massive vectors for infection. They are basically wheel and hub networks designed to optimise viral spread. Schools bring huge groups of people, a thousand and more, from every street in the community, to sit in small cramped rooms all day, then send them back to their homes, five days a week. With Universities you do this on a national scale with longer distances. These vast networks basically boost infection by forcing millions into close contact wil Amazon levels of distribution reach.


I took part in The Big Debate in Berlin this month. The motion was “This house belives that Education has failed to learn the lesson of Covid19”. I was up against the head of the NUS, who thought that “poor students who had to study in their pyjamas and dressing gowns” were “suffering badly from mental illness and loss of social contact”. Not only was this a caricature of education, as most people being ‘educated’ were in schools or the workplace, it was the usual placing of students on a social pedestal.


My retort was that viewing students as victims was an insult to the front line workers who had no choice other than to risk their lives, and sometimes die doing so, to keep us fed, supplied and safe - the delivery drivers, lorry drivers, paramedics, care home workers, police officers, bus drivers and factory workers - almost none of whom went to ‘Uni’.


I did argue that educators did a good job, many raising their skills as online educators under immense pressure. It was also good for both teachers and learners to raise their digital skills and literacy. Like Eric Mazur at Harvard,, I argued that it would be "almost unethical" to go back on those gains,


Rather than build on the advances we’ve made on Blending learning, the education system seems to be defaulting back to their old model. Why? Lecturing is easy, teaching is hard. We have a chance to make Higher Education cheaper, more accessible and efficient. We may blow it.

Tales of the absurd from Berlin

It was my first live conference for eons and the final session was a L&D roundup which was a bit of fun but two odd things happened. It was one of those bingo word events, where someone in the audience chooses a word from the screen and someone else stands up to say something for five minutes on that word. I can’t remember all of the words but they were things like ‘resilience’ and ‘curiosity’ and ‘obstacles’. When asked about ‘obstacles’ I put my hand up and said that I thought faffing around with abstract words in L&D had become an ‘obstacle’ to progress. 

BIG mistake, as I then heard the words ”Next we have (can’t remember their names) who will speak on ‘Resilience’”. To be fair the whole room laughed. If I’m resilient, it’s on one thing, trying to stop learning people rattle on about grit, resilience, or any other obscure, abstract noun, that no real people ever actually utter. We’ve only just put ‘mindfulness’ to bed, when a new one appears. I’ve had a bellyful of the stuff and lost interest when they were describing their ‘resilience meter’. It really is a thing. It just wasn’t my thing. Actually they were lovely people.


My SECOND mistake was to drift off, then coming round to hear “...so turn to the person next to you and give it a try” a phrase that makes my heart sink. I missed the first part of the sentence and on turning round, I said something and the person, who is a good friend of mine, started to object to what I said. She was repeatedly abrasive. My responses, at first polite, became angier and then I got obstreperous. Turns out it was a role-play, the key piece of information that had failed to register . A third person turned to me and said “You do know it’s a role-play?”. I apologised and all was fine. Again we had a bit of a giggle.


I suppose I’m just weary of this stuff, the idea that L&D is some sort of pop-up therapy service. Is this resilience thing much more than HR once again ticking people off for having a perceived deficit, a weakness, a flaw? Then there’s that old-school performative ‘turn to the person next to you’ BS. Are we really going back to that after Covid?

Stickgold & Walker Sleep and learning

Robert Stickgold is a US Professor of Psychiatry at Harvard Medical School, whose sleep research looks at the links between sleep and learning, especially sleep deprivation. He was a colleague and mentor to Matthew Walker, an English sleep researcher, now Professor of Neuroscience and Psychology at the University of California, Berkeley. His research is on sleep and his international bestseller Why We Sleep (2017) contains much that is relevant to the topic of sleep, memory and learning. His 2019 TED talk Sleep is your Superpower was also hugely popular, watched by millions.

Sleep and memory

Walker has written about the effects of sleep on student learning and recommends a rethink around the idea of end-of-semester exams that encourage cramming, even all-nighters. He has changed his own teaching to avoid final exams, splitting his courses up into thirds to spread the assessment load. 

Sleep before learning

Sleep is an active process that improves memory. When we are awake the hippocampus experiences and learns things in the real world, as a short-term location for new memories. It is also limited in capacity. It deals with this by shifting memories into other locations, namely the cortex, during sleep. You can test this using daytime naps and Walker compared a 90 minute ‘nap’ with a ‘no-nap’ group, after they performed a taxing 100 face-name pair task. Later that day, another intense learning task was performed, to see if learning had declined. Those that napped actually increased their ability to learn, while those that stayed awake showed a decline, the difference being a staggering 20%. It would appear that light, Stage 2 NREM sleep and short sleep spindles led to greater retention. It would appear that sleep refreshes our ability to learn, especially the later period of a night’s sleep. Getting up too early and shortening your sleep period seems to be deleterious to learning. This seems to decline with age.

Sleep after learning

What about after one has learnt something? Consolidation of memories has been posited for 2000 years, but it was Jenkins and Dallenbach (1924), who tested forgetting of verbal facts over eight hours, either awake or asleep. This has been replicated many times and forgetting in the group that was awake is greater, the benefits of sleep being 20-40% greater for the sleep groups.

REM and NREM  sleep was then discovered in the 1950s and the link between consolidation of memory and deep NREM was established, with MRI evidence indicating that memories literally move from the hippocampus to the neocortex during sleep. It would appear that your cache of memories gets cleared and stored every night, leaving  you ready for the next day’s learning. Sleep can also improve learning by recovering memories you lost while learning. It seems to rescue memories. Motor skills are also consolidated and enhanced during sleep.

Stimulating learning during sleep

Sleepers stimulated by electrical voltage pulses during deep NREM. The sleepers felt nothing but doubled their ability to recall facts learnt just before going to sleep. Quiet auditory tones synchronised with brain waves, from speakers next to the bed, have also been found to have an effect, namely a 40% improvement on recall. 

Sleep to forget  

When two groups were presented with words to remember but told to remember some (tagged R) and forget others (tagged F), the group that had a 90 minute nap had actively remembered more R words and forgotten more F words. It would seem that sleep is quite intelligent or active in what it selects as memories to be stored.

Sleep and emotions

Emotions or the affective side of learning are also influenced by sleep. The brain does reprocess or modulate emotions through sleep. Sleep deprivation encourages high emotional responses including aggression, bullying and behavioural problems in children.

Critique

Walker has been criticised for being slapdash with his data and references in his book. He has responded and apologised for some of its weaknesses.

Influence

Walker’s book and TED talk popularised sleep research and although he has been criticised for some inaccuracies, the benefits of sleep are now well known, especially among teachers and parents, worried by the rise in late night screen time.
