The Problem with How Most People Study
Re-reading notes. Highlighting. Re-watching lectures. These methods feel productive because they're comfortable — familiar content creates a sense of mastery.
But research is unambiguous: these methods are among the least effective ways to learn. Students who use them consistently underperform compared to those using active learning strategies.
Here are 8 techniques backed by strong evidence that replace effort with effectiveness.
Strategy 1: Active Recall (Retrieval Practice)
What it is: Testing yourself from memory instead of re-reading.
How to do it:
Why it works: Each retrieval attempt strengthens the neural pathway for that memory. Difficulty is the mechanism of learning — if it's easy, it's not building retention.
Evidence: Students who used retrieval practice retained 50% more information after one week vs re-readers (Roediger & Karpicke, 2006).
Strategy 2: Spaced Repetition
What it is: Reviewing material at increasing intervals, timed just before you forget it.
How to do it:
Why it works: Each review at the moment of near-forgetting strengthens and extends the memory trace.
Evidence: Distributed practice produces 200% better long-term retention than massed (cramming) practice.
Strategy 3: Interleaving
What it is: Mixing different topics within a single study session instead of focusing on one topic at a time.
How to do it:
Why it works: Interleaving forces your brain to identify which approach applies to which problem — a skill you need in exams.
Evidence: Students who used interleaved practice scored 43% higher on delayed tests vs blocked practice students.
Strategy 4: Elaborative Interrogation
What it is: Asking "why?" and "how?" rather than accepting information passively.
How to do it:
Why it works: Meaning-making creates richer, more retrievable memories than isolated fact memorization.
Strategy 5: Concrete Examples
What it is: For every abstract concept, generate at least two concrete examples.
How to do it:
Why it works: Abstract concepts without concrete anchors are easily forgotten. Examples create retrieval hooks.
Strategy 6: Dual Coding
What it is: Combining verbal and visual representations of the same information.
How to do it:
Why it works: Information encoded both verbally and visually is twice as likely to be retrieved.
Strategy 7: The Feynman Technique
What it is: Explaining a concept as if teaching it to a 12-year-old.
How to do it:
- Write the concept name at the top of a blank page
- Explain it in plain language without jargon
- Identify where your explanation breaks down
- Return to source material for those gaps
- Re-explain, even simpler
Why it works: Teaching requires the deepest understanding. Gaps in your explanation reveal gaps in your knowledge.
Strategy 8: Practice Tests Under Exam Conditions
What it is: Regularly practicing under conditions that mirror the actual exam.
How to do it:
Why it works: Exam performance is partly a skill. Practicing under realistic conditions builds that skill.
Study methods compared: what the research says
The eight strategies above are not equally well supported. The largest review of study techniques to date rated them like this:
| Method | What you do | What the research says | Source |
|---|---|---|---|
| Practice testing (retrieval practice) | Answer questions from memory before checking notes | Rated high utility; tested students remembered more a week later than students who re-studied | Dunlosky et al. (2013); Roediger and Karpicke (2006) |
| Distributed practice (spacing) | Spread reviews over days instead of one long session | Rated high utility; spacing beat massing across a large meta-analysis of verbal recall studies | Dunlosky et al. (2013); Cepeda et al. (2006) |
| Interleaved practice | Mix problem types within one session | Rated moderate utility; strongest evidence in maths problem solving | Dunlosky et al. (2013); Rohrer and Taylor (2007) |
| Elaborative interrogation and self-explanation | Ask "why is this true?" and explain each step | Rated moderate utility | Dunlosky et al. (2013) |
| Rereading and highlighting | Go over the text again, mark key lines | Rated low utility | Dunlosky et al. (2013) |
| Summarization | Write a summary of the material | Rated low utility, mainly because students need training to do it well | Dunlosky et al. (2013) |
"Dunlosky et al. (2013)" is the review *Improving Students' Learning With Effective Learning Techniques* by John Dunlosky, Katherine Rawson, Elizabeth Marsh, Mitchell Nathan and Daniel Willingham (Psychological Science in the Public Interest), which rated ten common techniques by how well the evidence supports them. The ratings are theirs; the one-line summaries are ours.
The two techniques with the strongest support, retrieval practice and spacing, are also the two a quiz does for you: every question is a retrieval attempt, and retaking it a few days later is spacing.
Building Your Study System
Combine these strategies into a weekly routine:
| Day | Activity |
|---|---|
| After each class | Active recall from memory (10 min) |
| Day 1 | Generate quiz, take it without notes |
| Day 3 | Spaced review — retake Day 1 quiz |
| Weekly | Mixed quiz covering all recent material |
| Before exams | Full practice test under exam conditions |
Studying on your phone
Most of these strategies don't require a desk. If your study time is scattered across a commute or between classes, see our guides to studying for exams on your phone, the best study apps for students in 2026, and the best AI study apps for iPhone for tools that fit active recall and spaced review into small pockets of time. If you're often studying without wifi, study-on-the-go tips for mobile learning and our roundup of the best apps for students on iPhone in 2026 cover offline-friendly options too.
Frequently Asked Questions
Which single strategy has the biggest impact?
Active recall (retrieval practice) has the strongest and most consistent evidence base. If you do nothing else, test yourself instead of re-reading.
How long should each study session be?
45–60 minutes of focused work, then a 10-minute break. After 4 sessions, take a 30-minute break.
When should I start using these techniques?
Day one. Don't wait until before the exam — spaced repetition requires time between sessions to work.
