I've been studying constructivism recently and ran across several articles that discuss how blogs, wikis and podcasts can be used as tools to turn theory into practical application. One of the most detailed is the eLearning Guild's Be Constructive: Blogs, Podcasts, and Wikis as Constructivist Learning Tools
This was an interesting read not only because of its practical pointers, but also because it adds credence to my previous rants about not using Web 2.0 tools just because they're cool. Instead, this article highlights ways to use these tools to assist learners in deliberately constructing their own learning environment.
Read it and let me know what you think!
