Make It Stick: The Science of Successful Learning

Research from cognitive science and classroom practice shows that many popular study habits are ineffective — and that learning is deeper and longer-lasting when we use strategies like retrieval practice, spaced repetition, and interleaving. Make It Stick debunks common myths and offers a science-backed roadmap to mastering knowledge.

Key Takeaways:

  • Retrieval practice strengthens memory and understanding
  • Spaced and interleaved learning outperform cramming
  • Struggle and effort during learning lead to stronger retention
  • Passive review (rereading, highlighting) gives a false sense of mastery
