How Blockchain is Helping Dallas Students Tell Their Story

By Stephen Downes - Stephen's Web. How Blockchain is Helping Dallas Students Tell Their Story
Tom Vander Ark, Getting Smart, 2019/02/19
This is a puff piece promoting Greenlight Credentials but it does offer one of the more compelling use cases for blockchain in education: "The benefit of a distributed ledger technology like Blockchain is that it allows employers and colleges to have instant verification of a multiple-source transcript." The key here is multiple-source. "Student profiles can host a range of evidences of learning including badges and a portfolio of artifacts." Of course, when you have multiple credentials in a single space, no one credential is special any more. More...

Does Web-Based Training Work?

By Stephen Downes - Stephen's Web. Does Web-Based Training Work?
The answer (as we all know by now) is yes, but in studies of effectiveness, "the instructional method matters, not the delivery medium." The same is true of testing; as Ewan McIntosh write, "people writing as fast as they can for two hours is no way to test whether children can 'perform'." More...

Study Questions RSS' Usefulness

By Stephen Downes - Stephen's Web. Study Questions RSS' Usefulness
I have been told that I am too critical. But stuff like this explains why. This post discusses a study by the University of Maryland's International Center for Media and the Public Agenda - surely a credibl;e agency, right? - suggesting that "RSS feeds from mainstream news sites aren't very useful in keeping up with the news" and that users would be better off using Google News. The study, of course, misrepresents how RSS is actually used. More...

Encyclopodia - the Encyclopedia On Your iPod

By Stephen Downes - Stephen's Web. Encyclopodia - the Encyclopedia On Your iPod
"Encyclopodia is a free software project that brings the Wikipedia, which is one of the largest encyclopedias in the world, to the Apple iPod. Encyclopodia can be installed on iPod genarations one to four, as well as on iPod Minis and Photo iPods." Too cool. Via Open Culture. Speaking of which, the Chronicle of Higher Education has a podcast. And Open Culture keeps its on list of academic podcasts. Also, My own podcast hassn't been updated for a while, but now that I have the whole presentations side cleaned up I am updating it again. Open Culture also links to "vast collections" of Frenc culture podcasts, which makes me wonder whether we are seeing the rebirth of the French Encyclopodiasts. More...

Who Needs OLPC?

By Stephen Downes - Stephen's Web. Who Needs OLPC?
This post mostly makes the point that the rising cost of the OLPC (now $175) and the declining cost of commercial computers (now $289) are close to reaching convergence. Yes, the OLPC has some neat features, like a way to generate its own power. If you can live without Windows and Office (which seem to be more expenseive than the computer these days) then you're already at OLPC territory - if your school board takes advantage of the low prices and isn't seduced by marketing.

The Illogical Rhetoric of Share Alike

By Stephen Downes - Stephen's Web. The Illogical Rhetoric of Share Alike
I don't agree with this post. I use 'share-alike' on my licenses (both Creative Commons and Open Source Software (where it's GPL) precisely because I don't want somebody coming along, doing a minor repurpose, and then claiming to 'own' the content. Leigh Blackall argues against 'share alike', though, because he can't use SA content in conjunction with proprietary materials, cultually restructed materials, or old commercial materials. Right. because such a combining would be a process of taking something that is freely sharable, and turning it into something that is not. It's just a clever way of raiding the commons for personal gain. But that said - there is nothing that presents the presentation of SA materials alongside commercial materials. You an still use the materials - you just can't pretend they are something you have created (and can restrict access to). More...

12 Important U.S. Laws Every Blogger Needs to Know

By Stephen Downes - Stephen's Web. 12 Important U.S. Laws Every Blogger Needs to Know
This post may be based on U.S. law, but the result is a good set of guidelines that constitute common sense in any jurisdiction. For example, "Never claim that you are an objective, unbiased source if you are being paid to provide information." Or "Always clearly distinguish between your work and someone else's." And this seems to be pretty obvious by now: "Never allow criminal comments or stolen content to remain on one of your sites." And for the commercial sites out there, "Never share or sell sensitive information such as social security numbers, credit card numbers, bank account information, criminal background or health records".

Games-Based Learning; a Serious Business Application

By Stephen Downes - Stephen's Web. Games-Based Learning; a Serious Business Application
Good white paper covering game-based learning in some detail. I like the author's approach: "Games-Based learning isn't about using simplistic 'Pong' or 'Who wants to be a millionaire?' as a means to teach people raw facts. That was the approach that edutainment took and which by and large failed." There's a longish list of links to other white papers on p. 6 and a large number of examples. More...

74 Quality Ruby On Rails Resources and Tutorials

By Stephen Downes - Stephen's Web. 74 Quality Ruby On Rails Resources and Tutorials
Rich McIver sends along this resource. I'm familiar with a number of the tutorials listed. Some of them are a but out of date (Ruby and Rails have gone through rapid version changes, an artifact of development). Others I looked at today and look useful. The How to Install for many many different operating systems seems especially useful. More...
