Ann Brown and Joe Campione have described one of the most revoutionary uses of classroom communities for learning
Essentially, students are jigsawed into specialization groups, with carefully selected access to resources, and carefully constructed activities, that eventually lead to specializations helping one another in constructuve activities.
For example, in "Peoples and Plagues" ... (review this activity)
It is interesting that this work has not been widely replicated outside of the partner schools, where it has been running for more than a decade. Primarily, this is because of the very high demands on the teacher and curriculum designer, as well as in classroom management - moving students around into different groups, providing them with timely access to resources, as well as clerar activities and instructions.
It seems that SSS could be used to create a very simple "FCL in a box" - where researchers could now specify the FCL design they wanted to explore, populate the system with content (possibly involving the design of new SAIL functionality, which would be shared in an FCL library). This could help revive this profound innovation, leading to further research and progress on the form.
