What should an instructor do to disengage students from a lesson?

Providing students with a new challenge or task is an effective way to disengage them from a lesson. This approach shifts their focus from the current material and can rejuvenate their interest. By introducing a new challenge, the instructor shifts the students' attention and encourages them to think critically or apply their knowledge in a different context. Engaging students in a task not only helps redirect their thoughts but also fosters a sense of curiosity and motivation to explore new concepts.

The other methods are less effective for disengagement. Stopping all activities could lead to boredom, while leaving students alone without tasks may create confusion or a lack of direction. Guiding them to review past materials, while helpful in some contexts, does not create a fresh focus that new challenges or tasks can stimulate. In a learning environment, keeping the engagement active is crucial, and offering new challenges is a productive way to navigate their attention.
