Dr. Kawtharani explains that smart studying makes study time more effective, rather than measuring learning by the number of hours spent studying or the number of times a lesson is reviewed. Real learning is measured by what a student can recall, understand, and apply without referring back to the book. The focus should therefore shift from “What should I memorize?” to “What have I understood, and what can I do with what I’ve learned?” Research in learning science supports retrieval-based learning and spaced practice, while emphasizing the importance of teaching students how to plan, monitor, and evaluate their own learning.
