I am a high school student and I was reading all the various articles on Social Constructionism on this and Martin's website and I very into the ideas behind it. I think that using social constructionist principles in the classroom in general could greatly help learning. I've seen examples of real life projects that utilize social contructionist principles (such as "Wikipedia") and how sucessful they are. One idea I had was that social constructionism could be used in a classroom to form their own WikiWiki of a specific subject. Students could write entries to it, modify other student's entries, etc. Some kind of WikiWiki module for Moodle would rock (is this similar to "workshop")? By the end of the year you'd have a very complete study guide for something that would be useful for an AP test.
Anyone have any ideas on how to get the word of social constructionism out to teachers?
