Negativity in MOOC: Impacts on Learning and Teaching and How Instructional Teams May Be Able to Address it

By Stephen Downes - Stephen's Web. Negativity in Massive Online Open Courses: Impacts on Learning and Teaching and How Instructional Teams May Be Able to Address It
Denise Comer, Ryan Baker, Yuan Wang, InSight : A Journal of Scholarly Teaching, Paperity, 2020/01/01
There is "a considerable amount of negativity in MOOCs," write the authors, "emerging from learners on discussion forums and through peer assessment, from disciplinary colleagues and from public discourse around MOOCs." This article (22 page PDF) looks to analyze it and maybe quantify it a bit. There are two case studies, and these help identify types of negativity (eg., toward the instructor, toward the platform).

Exploring Minds: Modes of Modelling and Simulation in Artificial Intelligence

By Stephen Downes - Stephen's Web. Exploring Minds: Modes of Modelling and Simulation in Artificial Intelligence
Hajo Greif, Perspectives on Science, 2020/01/01
Ignoring the title and main purpose of the paper (29 page PDF) for a moment, I encourage people to look at the first section for a really useful discussion of the various types of models that have been proposed through the years. Models might "bear observable and pre-theoretic similarities to their target systems." Or maybe they "are structures that express interpretations of a formal theory." Or maybe they " are structures that bear a formally defined relation of isomorphism to their target system," as Bas van Fraassen suggested in 1980. Whatever your definition (semantic, syntactic, or other) "models are epistemically more central to science than theories."
All of this becomes really important if you think of minds as being (or containing) models of knowledge, the world, or whatever, whether they are representations, reflections or whatever. More...

Online learning in 2020: perfect vision in the Year of the Rat

By Stephen Downes - Stephen's Web. Online learning in 2020: perfect vision in the Year of the Rat
Tony Bates, Online learning and distance education resources, 2020/01/01
Tony Bates offers three major prediction sets: first, that we may begin to see more online program managers (OPM) in Canada as the companies begin to lobby provincial governments; second, "we will certainly see a push from several right-leaning provincial governments in 2020 for better ‘metrics’ from universities and colleges, such as measures of ‘output’ (e.g. degree completion rates, graduate employment) as well as ‘input’ (finances, etc.)"; and third, while we may see more moves toward the use of learning analytics, the main issue here is measurement.

Making a Space for Disruption

By Stephen Downes - Stephen's Web. Making a Space for Disruption
This is an interesting way to look at e-learning 1.0 (the old LMS) and e-learning 2.0 (the new social network). "I find myself having two entirely different conversations with people," writes Janet Clarey. "One conversation will be about creating tracking workers' competencies, addressing skills gaps, managing the pre-hire to retire cycle, developing learning plans, and matching gaps to learning interventions... The other conversation will be about collaboration and connections - how to use wikis, blogs, social networks, virtual worlds, etc. and it will likely flow into discussions around control and culture." More...

Why (And How) I Just Canceled All My Music Subscriptions

By Stephen Downes - Stephen's Web. Why (And How) I Just Canceled All My Music Subscriptions
Although it was obvious to me (and presumably to readers of OLDaily) that signing up for a DRM-enabled music rental service would be a bad idea, we get confirmation of that in this article, in which the author finds that unsubscribing is not an easy process. More...

More On the NIH Victory

By Stephen Downes - Stephen's Web. More On the NIH Victory
I don't see this as the huge advance many writers do, but it is nonetheless a step forward. According to a bill signed into law this week, peer-reviewed manuscripts of U.S. government funded health research have to be posted and publicly available at PubMed Central no later than 12 months after publication.

A Framework for Assessing Learning Outcomes in Online Business Simulations

By Stephen Downes - Stephen's Web. A Framework for Assessing Learning Outcomes in Online Business Simulations
Good paper with a lot of background on the motivation for simulations, simulation design, and, as the title suggests, assessment of learning using simulations. The paper is better at the beginning and is recommended as an introduction to the pedagogy of simulations. I expected to see more on the evaluation of simulations and especially more linking the learning goals in simulations with the business goals of the organizations offering them. More...

Scaling MySQL at YouTube

By Stephen Downes - Stephen's Web. Scaling MySQL at YouTube
YouTube serves 100 million videos in a single day. It manages this daya with MySQL, an open source database engine. Which makes you wonder about the justifications for Oracle and MS-SQL. Anyhow, serving 100million videos, even with MySQL, is not without its, challenges, and that's the subject of this podcast. More...

IBM: LAMP Users Need to Grow Up

By Stephen Downes - Stephen's Web. IBM: LAMP Users Need to Grow Up
According to an IBM researcher, businesses that use LAMP (Linix - Apache - MySQL - Perl, Python or PHP) will have to "grow up". "They're really primative tools," says Daniel Sabbah, general manager of IBM's Rational division. "Eventually, they are going to have to come up against scalability." In a spirited response (language warning), Ryan Tomayko calls him on it. "The LAMP model works because it was built to work for and by people building real stuff. The big vendor / big tools model failed because it was built to work for Gartner, Forrester, and Upper Management whose idea of 'work' turned out to be completely wrong." I agree with Tomayko. "The need for complex systems in the enterprise was and still is greatly overestimated. The trick isn't to make PHP more complex, it's to make the enterprise less complex. More...
