When teaching, which action is least effective in promoting retention and understanding?

Using rote memorization techniques exclusively is the least effective strategy for promoting retention and understanding in teaching. This approach typically focuses on repetition and memorization without encouraging a deeper comprehension of the material. While rote memorization can help students remember specific facts or information temporarily, it does not facilitate critical thinking or the ability to apply that knowledge in different contexts.

In contrast, providing varied practice opportunities allows learners to engage with the material in different ways, enhancing their ability to recall information and apply it. Emphasizing the importance of learning fosters motivation and relevance, making students more likely to invest in their understanding. Encouraging interaction and discussion promotes active engagement, helping learners to clarify their thoughts, ask questions, and relate the content to real-world applications. These methods all contribute to a more meaningful and long-lasting understanding of the subject matter.
