We're now starting the post-lunch session on the first day here at WikiSym 2007, and the first paper is by Andrea Forte and Amy Bruckman, who examine the use of wikis as a toolkit for collaborative learning. Andrea begins by noting tha there is a significant deficit in media literacy amongst high school students - they don't necessarily have sufficient skills to evaluate the information they're confronted with. She suggests constructionism as a pedagogic framework for building such literacies.
Constructionism has been articulated by Seymour Papert - he suggests that people learn particularly well when engaged in the construction of public artefacts: when others see what you know and have done, when you can take pride in the work, and when the work is persistent into the future. This connects very well with working with wikis, of course, but also goes beyond them - it builds on students working on personally meaningful goals, and harnesses learners as capable, curious, and tenacious active practitioners. Online, especially, there are constantly new opportunities to employ constructionist learning.
