An Innovative Learning Strategy for Exams: 2-Stage Exams and 2-Stage Reviews. Students take an exam individually. Once they complete the exam they turn it in and get into a group with 3 other students. The students then take the identical test but this time they work together on the questions. There is one answer sheet for the group so they all have to come to agreement on each answer. Listening to their peers and arguing for their case helps them to understand the answer better, even if they had gotten the question correct on their individual test. This also works well for a review when students begin a new class and the instructor wants to review the prerequisite material. Directions for this strategy for taking and review the exam are here.
