Why is it critical for instructors to understand a student's prior knowledge?

Understanding a student's prior knowledge is crucial because it enables instructors to effectively build on what students already know. This foundational knowledge is essential for connecting new concepts to familiar ideas, which enhances comprehension and retention. When instructors are aware of a student's previous experiences and understanding, they can tailor their teaching strategies to address gaps, reinforce concepts, and challenge students at an appropriate level. This personalized approach fosters an environment where students can engage more deeply with the material, making learning more relevant and effective. Ultimately, it leads to greater academic success as students can integrate new information into their existing mental frameworks.
