What is Study Techniques? - Guide

Cognitive science research has identified a clear hierarchy of study technique effectiveness. At the top are active recall (self-testing) and spaced repetition (distributed practice), both rated as highly effective by multiple research reviews. In the middle tier are interleaving (mixing different topics), elaboration (explaining concepts in your own words), and concrete examples. At the bottom are commonly used but less effective methods like re-reading, highlighting, and summarizing.

The gap between popular and effective techniques is striking. Most students default to re-reading and highlighting because they feel productive and require low effort. But these methods produce weak memory traces. Active techniques like self-testing feel harder in the moment but produce substantially better long-term retention.

Combining multiple effective techniques produces the best results. For example, a student might use AI tools like Notella to generate flashcards from lecture notes (active recall), review them on a spaced repetition schedule, practice explaining concepts without looking at notes (elaboration), and mix topics within each study session (interleaving). This multi-technique approach maximizes learning per hour of study time.
