What should an average teacher do to ensure student understanding?

To ensure student understanding, it is essential to revisit points until mastery is achieved. Mastery refers to the point at which a student can demonstrate a solid understanding of a concept, allowing them to apply it effectively in various situations. This approach is particularly beneficial because learning is a cumulative process, requiring reinforcement and practice. By revisiting and practicing the material repeatedly, students can strengthen their comprehension and retention, ultimately leading to a deeper grasp of the subject matter.

In contrast, moving on quickly to the next lesson does not allow students the opportunity to fully absorb and master the content. Limiting discussions to a textbook restricts engagement and may prevent students from exploring the material in a more dynamic way, while focusing only on theoretical concepts can neglect practical application, which is crucial for understanding. Therefore, continuously addressing and revisiting points of confusion is vital for fostering a comprehensive understanding among students.
