Study Techniques That Actually Work According to Science
Science-backed study strategies that improve retention and grades, from spaced repetition to interleaving practice.
Active Recall: Testing Yourself Is the Best Study Method
Of all the study techniques tested in controlled research, active recall consistently produces the best results. Instead of passively re-reading your notes or textbook (which feels productive but is not very effective), close the book and try to recall the key concepts from memory. Write down everything you remember, then check what you missed. Use flashcards to test yourself. Write practice questions and answer them. This process, sometimes called 'retrieval practice,' forces your brain to strengthen the neural pathways associated with the information.
Spaced Repetition: The Forgetting Curve Is Real
Without review, we forget approximately 70 percent of new information within 24 hours. This phenomenon, documented by German psychologist Hermann Ebbinghaus in the 1880s, is called the forgetting curve. Spaced repetition combats this by reviewing material at strategically increasing intervals.
The Pomodoro Technique: Working in Focused Sprints
The Pomodoro Technique, developed by Francesco Cirillo in the late 1980s, structures study time into 25-minute focused blocks (called Pomodoros) separated by 5-minute breaks. After completing four Pomodoros, you take a longer break of 15 to 30 minutes.
Interleaving: Mixing Topics Beats Studying One at a Time
Interleaving is the practice of mixing different topics or types of problems within a single study session rather than focusing on one topic for an extended period (called blocking). For example, instead of spending an entire session on algebra, you would alternate between algebra, geometry, and statistics problems.
