Verisign chooses OpenID

By Stephen Downes - Stephen's Web. Boris Mann[Edit][Delete]: Verisign chooses OpenID, B. Mann Consulting [Edit][Delete] May 18, 2006
Boris Mann is "confused" but I find this to be very good news. OpenID is a system that is very similar to my own mIDm, specifically in that it is a distributed identity system - no centralized registry. Mann suggests, "I would follow this up with support for multiple identity protocols - that is, after all, Canter's Law: work with everything. You could have a single identity hosted by VeriSign and accessible via a variety of protocols, from OpenID to DIX to SAML to InfoCard." But no, you can't, not unless you can get the identity client and the service provider to agree to the same set of protocols. More...

Hot Air: How States Inflate Their Educational Progress Under NCLB

By Stephen Downes - Stephen's Web. Kevin Carey[Edit][Delete]: Hot Air: How States Inflate Their Educational Progress Under NCLB, Education Sector [Edit][Delete] May 18, 2006
I am a former North American NTN Trivia champion. I played on a team, of course, the Inglewood Collective. Part of our success was due to our knowledge. But a big part of it was due to our ability to understand how to win trivia games. I remember one day winning a 'Raceway Trivia' game - despite knowing nothing about auto racing - by playing probabilities. This is, as educators have long pointed out (I read it first in Holt), what students learn in a lecture and test environment: how to pass the tests. So it should be no surprise to learn that schools, school boards, and now entire states are learning to game the system. More...

Whose Space

By Stephen Downes - Stephen's Web. Ben Werdmuller[Edit][Delete]: Whose Space, E-learning, Web 2.0 and the World [Edit][Delete] May 17, 2006
This is a good article. It captures my own discontent with social networking sites (concerns I have expressed, say, in Public Spaces, Private Places and The Semantic Social Network). The author writes, "The model for the new web economy seems to be to run a single, centralised service that acts as a carrier for advertising... Result: "new" media is subject to the same business interests as the old media. This is a mistake." Ad-driven sites, whether content or application driven, depend on centralization, because they depend on traffic. And centralized sites, sooner or later, are subject to control. More...

7 Things You Should Know About Google Jockeying

By Stephen Downes - Stephen's Web. The EDUCAUSE Learning Initiative[Edit][Delete]: 7 Things You Should Know About Google Jockeying, Educause [Edit][Delete]EDUCAUSE [Edit][Delete] May 17, 2006
This is a neat idea I hadn't run across before. "A Google jockey is a participant in a presentation or class who surfs the Internet for terms, ideas, Web sites, or resources mentioned by the presenter or related to the topic. The jockey's searches are displayed simultaneously with the presentation, helping to clarify the main topic and extend learning opportunities." You know, I'm beginning to think I should ask for multiple screens and projectors at my talks - a screen for the Google jockey, a screen for the audience live conference chat (aka, the backchannel), a screen for the photo montage, and more. More...

The Death of Learning Object

By Stephen Downes - Stephen's Web. Albert Ip[Edit][Delete]: The Death of Learning Object, Random Walk in Learning [Edit][Delete] May 17, 2006
Some great quotes in this item: "What I like to say is that learning technology standards effort has focused at the wrong spot. Teachers do not need technologists to tell them how to do their job. Teachers do not need technologists to draw a square on the floor and be asked to stand inside the square. Teachers need tools, good tools so that they can use to craft their wares - whatever that may be. Blog is godsend. More...

Open Namespaces for Tags

By Stephen Downes - Stephen's Web. David Weinberger[Edit][Delete]: Open Namespaces for Tags, Joho the Blog [Edit][Delete] May 17, 2006
Yesterday David Weinberger suggested, "Shouldn't there be a non-vendor, open site that can serve as a namespace?" My response, in the first comment, was that "No, there shouldn't." The reason is that I don't think we should depend on a centralized aggregator, like Technorati, to organize tags. Quite a good discussion followed the initial exchange, and Weinberger was prompted to create a mock-up of what he wants. It is, of course, a clone of my own topic pages, something I've had on this site for, what, five years. More...

There's No Such Thing as a Learning Object

By Stephen Downes - Stephen's Web. Michael Feldstein: There's No Such Thing as a Learning Object, ELearn Magazine Elearn Magazine May 16, 2006
Michael Feldstein succinctly captures the problem with learning objects: "I believe the term 'learning object' has become harmful. It hides the same old, bad lecture model behind a sexy buzz phrase.... We learn by doing. We consider. We compare. We measure, discuss, debate, critique, test, and explore. We try, fail, and try again. Learning is an activity. It's a process. Given this undeniable fact, the term 'learning object' can only be an oxymoron. An object is a thing. More...

Live Blogging at Mesh

By Stephen Downes - Stephen's Web. Scott Karp[Edit][Delete]: Live Blogging at Mesh, Publishing 2.0 [Edit][Delete] May 16, 2006
Good summary of the discussion at Mesh, a media and Web 2.0 conference being held in Toronto yesterday and today, with presentations from Om Malik and Michael Geist. A lot of short information nuggets, not all of which ring true, but which are certainly worth a read. This is probably right: "There's a lot of value in advertising to small, pure, targeted audiences -- an extension of Google's AdWords. More...

A Weekend Reflection: Jodie Foster, Eminem, Middle School Cheerleaders

By Stephen Downes - Stephen's Web. Christian Long[Edit][Delete]: A Weekend Reflection: Jodie Foster, Eminem, Middle School Cheerleaders, think:lab [Edit][Delete] May 16, 2006
I have always liked Jodie Foster, but maybe that's just an appearance thing. And I've always liked Eminem, and that's a lyrics thing. Like this:
You better lose yourself in the music, the moment
You own it, you better never let it go
You only get one shot, do not miss your chance to blow
This opportunity comes once in a lifetime yo
And this is what Jodie Foster liked, and what Christian Long thought about as he watched inner city kids holding a car wash to pay for cheerleader uniforms. More...

Preparing for Intranet 2.0

By Stephen Downes - Stephen's Web. Kathleen Gilroy and Bill Ives[Edit][Delete]: Preparing for Intranet 2.0, the otter group [Edit][Delete] May 16, 2006
Good paper showing how web 2.0 technologies (and especially blogging) can be used in a corporate context. Contains one of the best one-paragraph descriptions of a learning network I've seen: "A learning network uses the intranet as a platform to tie together a set of services that support collaboration and communication, and it uses the web 2.0 tools we ve described so far". More...
