What should teachers avoid doing when a student appears to already understand a concept?

Teachers should focus on fostering an environment that promotes understanding and growth based on a student’s current level of comprehension. When a student demonstrates that they already understand a concept, introducing distractions with unrelated material can disrupt their learning process. Instead, the teacher should aim to build on the student’s knowledge, either by providing further relevant exercises, extending the lesson into more complex areas, or assessing their understanding through checking answers. Keeping the student engaged with material that reflects their current understanding is key to effective teaching, and unnecessary distractions can lead to confusion and disengagement. Therefore, avoiding unrelated material is essential to maintain a focused and constructive learning atmosphere.
