I established groups with at least one "computer guru" in each group to minimize the time I would need to spend with groups on computer issues. I also left detailed instructions in a packet at each station that explained what each group was to do. Also in each packet was a list of Frequently Asked Questions (FAQ's) that I thought students would ask. If any student came to me with a question that was already on the FAQ list, they were deducted points for that assignment.
