Recently I was asked to help design an interactive whiteboard application for the classroom. it is going to be a playful educative application about the basics of music production. The teacher is going to use it mostly, but the children also have to use it in some cases. One of the core teaching methods is collaboration.
My question is if there are any guidelines how to design such an application? The do's and don'ts? It also would be great if someone knows some good examples.
