Teaching Others

The "protege effect" is well-documented: students who prepare to teach material learn it more deeply than those who prepare to be tested. When you know you'll need to explain something, you organize information hierarchically, identify gaps, and generate examples — all high-level processing. A 2018 study in Applied Cognitive Psychology found that students who taught material scored 9% higher on subsequent tests. Even the illusion of teaching (explaining to an imaginary audience) produces significant learning gains.
