I have experienced that communication between teachers, children and parents can sometimes be quite incomplete and full of gaps. Messages disappear or are misunderstood. Many things are redundant. As most parents, children and teachers have access to internet I have thought about introducing a 2.0 solution for all parties of the class. Instead of writing messages and copying them for parents teachers could post them online. Instead of informing about a child's absence via phone parents could deposit a few words online. And many more things.
Has anyone of you introduced an open-source 2.0 tool for that purpose? Which experience have you made? I would love to exchange experience with you and develop some new ideas.
