George Siemens, Stephen Downes, and Dave Cormier - have had over 10,000 participants in the various courses we've run since 2008. The learning experience has been terrific. We've refined our pedagogical approaches, improved the software (well, actually, just Stephen did that), and developed a research agenda around learning in networks in open online courses... If you are interested in joining, please register for the course. We will be posting more information over the next few months.

"On Wednesday, February 8th, Wolfram Alpha will be adding a new, "Pro" option to its already existing services. Priced at a very reasonable $4.99 a month ($2.99 for students), the new services includes the ability to use images, files, and even your own data as inputs instead of simple text entry. The "reports" that Wolfram Alpha kicks out as a result of these (or any) query are also beefed up for Pro users, some will actually become interactive charts and all of them can be more easily exported in a variety of formats. We sat down with Stephen Wolfram himself to get a tour of the new features and to discuss what they mean for his goal of "making the world's knowledge computable.""
