Teachers and technology: time to get serious

By Stephen Downes - Stephen's Web. Teachers and technology: time to get serious
Neil Selwyn, Impact, 2019/01/22
According to this article, "The most useful education technology knowledge does not come from globe-trotting ‘gurus’, keynote speakers and product evangelists. Instead, the best technology advice can often come from simply trying things out for yourself and/or speaking with colleagues working in similar situations and circumstances." This is both true and not true. It's true in the sense that nobody understands local needs and conditions better than the people working with them. On the other hand, the speakers and gurus are often longtime experts in the field. Not always, of course. More...

Thanks to rapid, 3D imaging, anyone can tour the fly brain

By Stephen Downes - Stephen's Web. Thanks to rapid, 3D imaging, anyone can tour the fly brain
Robert Sanders, Berkeley News, 2019/01/22
This 3D view of a fly's brain shows even a simple insect's neural network can be large and complex. The accompanying video points to different areas of the brain that do different things, but it's important to keep in mind that they entire structure is densely interconnected. The images are the result of new scanning technology, which is described in this article. More...

Institutional Innovation - I Have a Dream

By Stephen Downes - Stephen's Web. Institutional Innovation - I Have a Dream
John Hagel, Edge Perspectives, 2019/01/21
I'm not sure how appropriate it is to use Martin Luther King day in the service of institutional innovation. In any case, the transformation Hagel describes involves something called 'scalable learning ' - "learning in the form of creating new knowledge through action and reflection on results – it’s not about sharing existing knowledge or just coming up with new ideas." Fair enough, though not exactly new or novel. Hagel outlines the process in terms of motivation (away from the financial, toward passion and need), practices (from static and routine, to dynamic and challenging) and environment. More...

'It's all about controlling students': researchers slam popular app

By Stephen Downes - Stephen's Web.'It's all about controlling students': researchers slam popular app
Henrietta Cook, Sydney Morning Herald, 2019/01/21
Used in more than half of Australian primary schools, according to this article, Class Dojo is nonetheless being "slammed" by researchers from the University of South Australia who say it "promotes an archaic approach to discipline and likens it to China's social credit system." This article (17 page PDF) appears at the same time the Guardian posts a report entitled Welcome to the age of surveillance capitalism. Surveillance capitalism, writes Shoshana Zuboff in a new book, "unilaterally claims human experience as free raw material for translation into behavioural data" in order to create "behavioural futures markets" predicting, and ultimately controlling, human behaviour. More...

OER Survey and Adoption Growth: It pays to check source material

By Stephen Downes - Stephen's Web. OER Survey and Adoption Growth: It pays to check source material
Phil Hill, e-Literate, 2019/01/21
I had my own issues with the accuracy of a recent Chronicle's report on an OER study, and Phil Hill does a little fact-checking of his own and finds more problems. "The second paragraph shows a potential drop in adoption over the next three years for all faculty," he writes. "That would be major news showing that the OER movement hit an inflection point." But the study says nothing of the sort. "This survey asks faculty members who are not current users of open educational resources whether they expect to be using OER in the next three years. More...

Knowledge, Skill and Virtue Epistemology

By Stephen Downes - Stephen's Web. Knowlege, Skill and Virtue Epistemology
Duncan Pritchard, Handbook of Skill and Expertise, 2019/01/21
This is just one bit of Duncan Pritchard's voluminous output. It makes me think about the relation between knowledge, on the one hand, and the skill or virtues needed to produce knowledge on the other, in other words, between cognitive success and cognitive agency. "there is a way of thinking about knowledge that takes the idea that knowledge involves cognitive skill or ability as primary," writes Pritchard. More...

Web Authentication: An API for accessing Public Key Credentials

By Stephen Downes - Stephen's Web. Web Authentication: An API for accessing Public Key Credentials
W3C, 2019/01/18
This probably belongs in the E-Learning 3.0 course (under the 'identity' section) but it's part of educational technology in general (we don't talk about it a lot, but authentication and passwords make up some of the biggest usability issues in ed tech). "This specification defines an API enabling the creation and use of strong, attested, scoped, public key-based credentials by web applications, for the purpose of strongly authenticating users." We are at some point going to get this right (even if the web technology silo companies don't like it). More...

Why Data Is Never Raw

By Stephen Downes - Stephen's Web. Why Data Is Never Raw
Nick Barrowman, The New Atlantis, 2019/01/18
There's so much emphasis on things like evidence-based decision-making, or data-driven learning, as though the proponents had never read Kuhn, Lakatos and Laudan. It bears repeating, especially in these days of big data, that "data is never simply given, nor should it be accepted on faith. How data are construed, recorded, and collected is the result of human decisions — decisions about what exactly to measure, when and where to do so, and by what methods". More...

A Collaborative Way of Learning Project Management with Minecraft

By Stephen Downes - Stephen's Web. A Collaborative Way of Learning Project Management with Minecraft
Claudia Alcelay, International Journal of Advanced Corporate Learning, 2019/01/18
This is a short paper (3 page PDF) on the use of Minecraft to support game-based learning for project managers. Minecraft was chosen, writes Claudia Alcelay, because it is collaborative and user actions are traceable. The idea is that students plan their projects, and then enter Minecraft and build according to their project plans. Then they can measure how they performed against what was plan, calculate things like earned value, and essentially emulate the planning and reporting process. More...

LEGO in the Lab

By Stephen Downes - Stephen's Web. LEGO in the Lab
Charles Rapple, The Scholarly Kitchen, 2019/01/18
This article doesn't have much article to it, but there is a set of links pointing to interesting examples of how Lego is used in the lab and in the classroom (I wish I could see more than just the abstract for the Lego-Github presentation). I have to confess, though - when I was a kid there were two types of people in the world, Lego people, and Meccano people, and I was a Meccano person. More...
