When integrating tech in the classroom I think we need to further our questioning when thinking about purpose. We need to ask ourselves a whole list of questions. I presented these at ECCO last year in my presentation about Google Docs. When thinking about integrating any tech, ask yourself:
How will the technology support...
social learning and communication?
differentiation for learners who learn best textually, auditorily, kinesthetically?
assessment and marking (teacher, self, and peer)?
