Closure in a lesson serves the important function of helping students confirm their understanding of the material that has been taught. This stage typically comes at the end of a lesson and provides an opportunity for both the teacher and students to reflect on what has been learned. During this time, students can articulate their comprehension and synthesize key concepts, which reinforces their learning. By summarizing their knowledge and connecting it to the lesson's objectives, students can identify areas where they feel confident and aspects that may need further clarification. This process not only aids retention of information but also empowers students to take ownership of their learning journey.

Engagement with peers, efficient completion of homework, and introducing new material, while valuable aspects of education, do not primarily capture the essence of closure, which is fundamentally about assessing and solidifying students' understanding of the content covered in the lesson.
