When should a teacher fall back on prerequisite knowledge?

Falling back on prerequisite knowledge is essential when a student is having trouble. This approach allows the teacher to identify gaps in the student's foundational understanding that may be affecting their ability to grasp new concepts. By revisiting prerequisite knowledge, the teacher can reinforce prior skills and ensure that the student has a solid base upon which to build new learning.

Addressing difficulties in understanding can prevent frustration and promote a more confident approach to new material, ensuring students feel supported as they work to overcome their challenges. This method not only aids in comprehension but also enhances the overall learning experience by creating a more cohesive flow of information.
