SP2 Chybie points me toward a local primary school context, where working together is part of everyday learning. I am interested in how pupils understand a shared goal and make room for different ways of contributing. That is the theme I associate with SP2 Chybie classroom cooperation. A group task can teach more than its final subject when students discuss how they divided the work. I like attention to the quieter contributions that may disappear when only the finished result is presented.
