I have found that giving the students a list of true/false questions after a lecture and telling them they can use any resources in the room other than the answer sheet and the instructor (we can answer process questions but not answers to the questions) promotes a team environment. The instructor can check each student’s answers one time. At this point the instructor can indicate the number right with no indications of which ones are correct. Students who have a hard time participating are now drawn to the team as small groups turn into one large team of all class members. They soon realize that the whiteboard is a resource and control the flow of students having their answers checked comparing each student’ answers to the answers on the board. Make sure there are more questions than students. In addition to a great team building exercise this helps with evaluation of students.
