Lesson designs that have weak closure rob students of the most important part of the lesson--the time when they have the opportunity to think about and discuss what they have learned. This is the time in the lesson when students reflections is necessary for internalization of the skills covered. At the end of a lesson, a short concentrated time period of 5 to 8 minutes should be set aside to provide students with the opportunity to evaluate lesson content and to reinforce skills taught. Activities must be designed to maximize student input. Fifteen student-directed activities, 11 lesson-focused activities, and 11 teacher-directed activities are described. These activities are designed to stimulate teachers at all grade levels to think of more effective ways to complete lessons. (JDD)
