Scott Wilson has another interesting post in his Workblog. In part he writes:
From now on instead of courses I’m going to talk about shared learning contexts (SLCs). Courses are a good word to describe a lot of things in formal education, but isn’t broad enough to cover similar groups of functionality in informal settings, so this is a new term to cover anything that provides a space where a group of people engage in learning, whether informal or formal, and wether or not there is any sort of assessed outcome.
The rest of the piece describes how various web services could be aggregated for educational purposes using the IMS enterprise services standard. The last of several diagrams illustrates how a “personal learning environment” might draw elements from institutional and other sources which might be an LMS with services exposed.
