A while ago, I had students working on group projects, writing news reports in our Disasters Unit in grade 7 ELA. They were to be making their presentations. One student was home after hurting her leg while riding her horse the day before. Her two partners needed her.
Before I knew what was happening her voice was coming through the speakers loud and clear and she was giving her part to the presentation with her partners. Later, she was also able to send in her information through her google doc.
Students using the tools made available to them. You gotta love it.
