If your students use Google Docs, you can help them learn a great skill: working collaboratively on an online document (or a Slide Show). I have had kids work on one essay in a group of 4-5 students; with fewer essays to grade, I can give more meaningful feedback for each essay. Technology is not going away, and our kids are going to have to know how to work on shared projects with other people in college and in the workplace, people who may not only not be in the same room as them, but maybe not even in the same country! This is a document I created to help explain WHY this skill is important to learn, and to provide the etiquette rules of working together on an online project. No guarantees that you won't still encounter whining or kids stepping on each others' toes, but introducing this document before beginning the project at least sets the tone that this is important and we take it seriously.
