OK, So Stephen Downes Doesn't Like the LMOS

By Stephen Downes - Stephen's Web. Michael Feldstein[Edit][Delete]: OK, So Stephen Downes Doesn't Like the LMOS, E-Literate [Edit][Delete] January 31, 2006

[link: Hits] Michael Feldstein wasn't too happy with my post from yesterday. He writes, "I think language like 'ridiculous' and 'absurd' is unnecessarily hyperbolic... It's also not terribly collegial or respectful. And finally, it doesn't reflect a grasp of the problems we are trying to solve." The problem they are trying to solve is this: "SUNY has 64 campuses with 414,000 students... Somebody has to provision all of those courses from a server, make sure it all scales, and support all of those applications." But if you try to build one system that will automate everything for that many people, you get (in my view) an unsustainable (and very expensive) mess. I would never try to serve so many people from a great big server with a predefined architecture; indeed, I have argued at length over the years that this is exactly what shouldn't be done. More...

Why Mashups Make the LMOS

By Stephen Downes - Stephen's Web. Mark Feldstein[Edit][Delete]: Why Mashups Make the LMOS, E-Literate [Edit][Delete] January 30, 2006

[link: 6 Hits] I have been sort of sympathetic to the concept of the learningmanagement operating system (LMOS) because, after all, the concept includes things that I favour: distributed resources, user access to the underlying system. But I began to falter when Mark Feldstein said "We don't just want to offer many different affordances. we want to orchestrate them." And following his link to Bernie Durfee has sketched out a first use case implementation sent me over the edge. I'll say it bluntly, and apologize later: this is the most ridiculous thing I've seen. Durfee is describing what the rest of understand as 'upload a file and base a discussion thread on it'. Something I did right here in about 10 seconds today". More...

Online Material Decreases Class Attendance?

By Stephen Downes - Stephen's Web. Henry E. Schaffer[Edit][Delete]: Online Material Decreases Class Attendance?, EDUCAUSE Blogs [Edit][Delete] January 30, 2006

[link: 4 Hits] As usual, poor and incomplete research results in contradictory reports about the impact of technology in the classroom; one study says the use of iPods caused no change, while another (consisting apparently of a reporter asking some friends) draws the opposite conclusion. If we look at the reporter's 'data', though, what we find is a communications professor who, even with no resources posted online, could only attract 60 to 70 percent of his students (yes, apparently 30 percent of his students decided that seeing nothing was better than sitting through one of his lectures). So I have only one response when I see a statement like this: "the result, Allen said, was that only about one-third of her 154 students showed up for most lectures". More...

Welcome to PLoS Computational Biology Education

By Stephen Downes - Stephen's Web. Fran Lewitter[Edit][Delete]: Welcome to PLoS Computational Biology Education, PLoS Computational Biology [Edit][Delete] January 30, 2006

[link: Hits] The Public Library of Science journal Computational Biology announces a new column on education. They write, "Tutorials and reviews are only the beginning. Over time, we will explore ways to present educational information in this digital age that can take advantage of technological innovation. In addition to text-based information, we are considering multimedia presentations and other media to enhance the written word". More...

North Korea and South Australia Agree on Censorship: Web 2 Banned

By Stephen Downes - Stephen's Web. Leigh Blackall[Edit][Delete]: North Korea and South Australia Agree on Censorship: Web 2 Banned, Teach and Learn Online [Edit][Delete] January 30, 2006

[link: 9 Hits] The only consolation - if there is any - is that North Korea and South Australia are by no means alone in their dislike for new web technologies. Still. Leigh Blackall comments, "Some might say, 'take it to the media Bill, blow the lid off it' - but from what I've seen and heard on the mainstream media toilet papers, teleblindness and radio monotony, they're buying into the fear frenzy and are not interested in representing a range of views on Internet censorship in schools." Perhaps if we set a better example, we wouldn't be so worried. Related: Judy Breck ,a href="http://goldenswamp.com/2006/01/30/teaching-information-literacy-skills-or-censoring-kids/">comments, "What scares me is there is not the least hesitation in the article to assume educators must approve what students study".

Public Schools Win! (Maybe)

By Stephen Downes - Stephen's Web. Tim Stahmer[Edit][Delete]: Public Schools Win! (Maybe), Assorted Stuff [Edit][Delete] January 30, 2006

As Tim Stahmer cites, "A large-scale government-financed study has concluded that when it comes to math, students in regular public schools do as well as or significantly better than comparable students in private schools." As Tim Stahmer comments, "But itâxTMs certainly not enough to force the death of NCLB and declare victory over the charter/voucher concept". More...

George Siemens and Stephen Downes - On Knowledge

By Stephen Downes - Stephen's Web. Stephen Downes, George Siemens, Jeff LeBow and Dave Cormier[Edit][Delete]: George Siemens and Stephen Downes - On Knowledge, Ed Tech Talk [Edit][Delete] January 30, 2006

[link: Hits] So George Siemens and I had a chat on Ed Tech Talk Sunday about issues arising out of my Connective Knowledge paper and his comments about my scepticism about objective knowledge. Here's the MP3 Audio and the chat Transcript. As an added bonus, Dave Cormier and I chatted at length Sunday evening about the show and related issues. Now I rarely (well, never) post chat transcripts, but this particular transcript catches me at just the right time and allows me to share thoughts and feelings you can't really capture in a paper or forum such as took place earlier. So, with Dave's gracious permission (because the chat was never intended for publication), here's our discussion (click here). [Tags: Chat and Chat Rooms, Podcasting] [Comment] [Edit]. More...

Models for Sustainable Open Educational Resources

By Stephen Downes - Stephen's Web. Models for Sustainable Open Educational Resources

Though there is great temptation to depict the sustainability of OERs in terms of funding models, technical models or even content models - and no shortage of recommendations regarding how each of these should proceed - it seems evident that any number of such models can be successful. But at the same time, it also seems clear that the sustainability of OERs - in a fashion that renders then at once both affordable and usable - requires that we think of OERs as only part of a larger picture, one that includes volunteers and incentives, community and partnerships, co-production and sharing, distributed management and control.

Era Ends: Western Union Stops Sending Telegrams, LiveScience

By Stephen Downes - Stephen's Web. Robert Roy Britt[Edit][Delete]: Era Ends: Western Union Stops Sending Telegrams, LiveScience [Edit][Delete] February 2, 2006

[link: 2 Hits] A headline from fifty years ago? No, it's from last week. The Western Union telegraph has a long and storied history but it's odd to think of people still sending telegrams in 2006, illustrative of the time it takes one technology to replace another. Still, I never sent a telegram in my life. More...

Failure of Online Communities

By Stephen Downes - Stephen's Web. Harold Jarche[Edit][Delete]: Failure of Online Communities, Jarche Consulting [Edit][Delete] February 2, 2006

[link: 8 Hits] Harold Jarche cites Jay Cross, who remarks en passant, "After the session, several people told me they really appreciated Bill telling it like it is. Early on, he said that while he thought he was pretty good at fostering online communities, 90% of the communities he sets up fail." Bill probably is good at setting up online communities. But I wonder whether a community that has been set up is doomed to fail. I wonder whether, instead, what we should be looking at as community is the interactions between people in a distributed environment - such as the network of blogs and readers and commenters that make up what might be called the edublogging community (actually several communities, but I digress). A seminar, a meeting space, an online discussion board - these are not communities. More...
