The star link of this post is the online university: Udacity.
It seems that there is plenty of interest in this domain. I'm currently having some time off work, but that doesn't stop me checking my work emails - and I was happy to read the following email (and discover all the exciting links).
I would have written a comment directly on the blog, but I am no longer a UK resident, therefore unable to sign in to leave comments.
Open online education has definitively hit its stride since last year.
Udacity also stands out along with the other initiatives. It was founded by Sebastian Thrun, of Google driverless car fame, following a successful online Stanford lecture with Peter Norvig last Summer. Sebastian Thrun recently hosted a great IAMA Reddit about online education.
In parallel, education initiatives trying to reach a larger audience by harnessing the web and social media are emerging. For instance, Darius Arya (twitter @SaveRome), at the American Institute for Roman Culture in Rome, is bringing archaeology and conservation work to multiple media formats (web, social media, video) to increase visibility, via his annual Unlisted conference (see this youtube video as an example).
Thank you for the blog, have a great weekend!
