Unity vs Unreal Engine for XR Development: Which One Is Better?

By Stephen Downes - Stephen's Web. Unity vs Unreal Engine for XR Development: Which One Is Better?
Dejan Gajsek, Circuit Stream, 2019/12/30
The answer is, as it always is in comparisons like this, it depends. The article offers a quick outline of each engine, compares the asset stores, links to documentation and training, talks about the development community, illutrtes (with examples) the development process, and notes that "there’s one major difference between UE4 and Unity3D. Unreal Engine 4 is an open source engine. Unity3D is not." Also, Unreal is based on C++, while Unity is based on C#. More...

Could exams be marked by AI? Ofqual launches ‘exciting’ competition

By Stephen Downes - Stephen's Web. Could exams be marked by AI? Ofqual launches ‘exciting’ competition
Freddie Whittaker, Schools Week, 2020/01/09
I really think it's only a matter of time before all student work is marked by AI. At a certain point, it will be hard to justify using human markers when AIs are demonstrably more fair and more reliable. But of course, this still needs to be demonstrated. That's where this work comes in. More...

Ten simple rules for structuring papers

By Stephen Downes - Stephen's Web. Ten simple rules for structuring papers
Brett Mensh, Konrad Kording, bioRxiv, 2020/01/09
Needless to say, I don't structure my papers this way. Never have, never will. That said, I can see the logic of the structure and have no problem recommending it to others. There's an especially helpful diagram part way through the paper that describes the structure. Basically the idea is: summarize what other people know and find a problem; gather and analyze some data to address the problem; summarize the gap filled by your work and outline its limitations. So, why don't I use this method? It's hard to explain - my 'data' is my newsletter, which I can't really summarize. Also, I'm never working on one idea at a time. No piece of my work should be viewed outside the context of all the rest of my work; it's all one big work. And I'm not interested in problems so much as I am interested in new ways of seeing and imagining possibilities. More...

Art, Science, and the Role of Data in Education

By Stephen Downes - Stephen's Web. Art, Science, and the Role of Data in Education
David Wiley, iterating toward openness, 2019/04/04
The best line in this post is this: "each year in the US, we turn out thousands of students who have learned the rules Bach used to write four part chorales... but even though we train thousands of students, year after year, we haven’t seen another Bach." Of course, part of the reason for this is the same as the reason we can make most students above-average: the second person who is equal to Bach, even if equally talented, can't be Bach. And of course the United States has produced acres of brilliant musical talent over the years, as original and creative as Bach, but of course, not Bach. The pedantry aside, I agree with Wiley's overall point, that any discipline is a mixture of art and science. More...

'No Man's Sky VR' is the purest way to explore the universe

By Stephen Downes - Stephen's Web. 'No Man's Sky VR' is the purest way to explore the universe
Jessica Conditt, Engadget, 2019/04/04
I've been playing No Man's Sky since almost the day it launched and this is the upgrade I've been waiting for: VR. The game had a rocky launch; it was basically just a sketchy universe and some controls. But the potential was obvious even then. No, according to this report. this summer's update will include for virtual reality. More...

The social value of anonymity on campus: a study of the decline of Yik Yak

By Stephen Downes - Stephen's Web. The social value of anonymity on campus: a study of the decline of Yik Yak
Sian Bayne, et.al., Learning Media and Methodology, 2019/04/04
This is a study of YikYak in education. "Yik Yak was a social media application which was designed according to the three principles of anonymity, hyper-locality and community moderation, and focused specifically on user appeal on university campuses." The potential for problems was clear. "There were several well-publicised incidents of hate and victimisation over the period of the life of Yik Yak." But did the value make up for that? "Yik Yak was not for the most part a toxic environment." And when in 2016 YikYak curtained anonymity its popularity plummited. The authors suggest that unreachability holds significant social value for students". More...

Arizona State Working with Community Colleges in Interactive OER Pilot

By Stephen Downes - Stephen's Web. Arizona State Working with Community Colleges in Interactive OER Pilot
Dian Schaffhauser, Campus Technology, 2019/04/04
The initial concept is laudable. "What Anbar has in mind is something he calls "active OER." That's taking the standard digital textbook and expanding it with the addition of digital resources, including simulations that are both interactive and adaptive." So is the committment of $25 million to the project. But why then would it be narrowed down to one commercial provider? "That's where Smart Sparrow comes in: The company produces aero, a learning platform that allows the instructor to pull together lessons from a set of templates." This is in many respects the opposite of extending OERs with interactive resources. More...

The Creeping Capitalist Takeover of Higher Education

By Stephen Downes - Stephen's Web. The Creeping Capitalist Takeover of Higher Education
Kevin Carey, Huffpost, Highline, 2019/04/04
"Just a few years ago," writes Kevin Carey, "universities had a chance to make a quality education affordable for everyone. Here's the little-known and absolutely infuriating history of what they did instead." I'm not sure how little-know it is; after all, the sector's failure has been chronicled over 20 years in these pages. But the core observation is dead on. More...

Fediverse field trip

By Stephen Downes - Stephen's Web. Fediverse field trip
Doug Belshaw, Open Educational Thinkering, 2019/04/04
This is a look at a number of the lesser-known federated social networking applications (known collectively as the 'fediverse', and known as 'federated' because there is no central website, but rather a 'federation' of interconnetced websites). More...

Springer Nature publishes its first machine-generated book

By Stephen Downes - Stephen's Web. Springer Nature publishes its first machine-generated book
Springer Nature, 2019/04/04
It seems reasonable that an AI could author this sort of book. The prototype "provides a compelling machine-generated overview about the latest research on lithium-ion batteries, automatically compiled by an algorithm." Scientific papers have a fairly rigid structure, and so it should be reasonable straightforward to create a literature summary. More tricky would be identifying relevance of individual results and placing them into a wider context. More...
