I've been working on the development of an e-learning course that maps learning outcomes to the 6 levels of Bloom's cognitive domain. The course itself is self-paced and meant to run from a website or cd-dvd. I've completed lessons one through four, with one being the introduction to the module. Lessons 2, 3, and 4 focus on the Knowledge, Comprehension, and Application levels of the domain. Each lesson contains recommendations for using social networking tools (i.e. blogs, wikis, social networking sites) to foster learning.
