In this professional development video excerpted from Getting Results, a community college instructor explains how he reviews a test with his students by having his students work in groups to discuss answers. The instructor explains that while tests can reveal to him what hasn't been grasped, this group review helps his students reflect on the rationale behind each answer. In addition, the tests help him discover whether goals are met, whether there are other benefits to the lesson, and whether he was successful in teaching the lesson. Once he has discovered the answers to these questions, he can decide whether to adjust the course design.
