# Learning Science

## The four most powerful learning strategies (research-backed)

### 1. Retrieval practice (testing effect)

Recalling information from memory is more effective than re-reading or re-watching.
How to implement: Flashcards, practice tests, closed-book recall, teaching others.
**Effect size:** Among the largest of any learning intervention.
The act of retrieval itself strengthens memory — not just the feedback.
Even failed retrieval attempts (then checking the answer) strengthen memory more than passive review.

### 2. Spaced practice (distributed practice)

Spread study sessions over time rather than cramming.
Studying 30 min/day for 5 days >> studying 2.5 hours once.
Spacing effect works because memories need time to consolidate and retrieval strengthens them at just the right moment of forgetting.
**How to implement:** Plan review sessions at increasing intervals (1 day, 3 days, 1 week, 2 weeks, 1 month). Apps: Anki (free, open-source) uses spaced repetition algorithm.

### 3. Interleaving

Mix different types of problems/topics within one study session rather than blocking.
"Block practice": Practice all addition, then all subtraction.
"Interleaved practice": Mix addition, subtraction, multiplication problems.
Interleaving feels harder and slower initially but produces better long-term retention and transfer.
Particularly powerful for discrimination tasks: "When should I use formula A vs. formula B?"

### 4. Elaborative interrogation

Ask "why" and "how" — connect new information to what you already know.
"Why does this make sense?" "How does this connect to X?" "What would happen if...?"
Forces deep processing rather than surface encoding.

## What does NOT work well

**Re-reading:** Low effort. Low effect. Gives illusion of learning from familiarity.
**Highlighting:** Virtually no effect on learning. Feels productive. Isn't.
**Massed practice (cramming):** Short-term gains, rapid forgetting. Poor for long-term retention.
**Listening/watching without active engagement:** Passive learning has low retention.

## Metacognition

Thinking about your own thinking. One of the strongest predictors of academic success.
**Calibration:** Accuracy of predicting your own performance. Most learners are overconfident.
**Monitoring:** Check your understanding while learning (don't wait for the test).
Self-testing is the best monitoring strategy. If you can't recall it, you don't know it.

## The importance of prior knowledge

New learning hooks onto existing knowledge. The more you know about a subject, the faster you learn more about it.
**Implication:** Build fundamentals deeply before moving to advanced material.
**Worked examples:** For novices, worked examples are more effective than problem-solving. As expertise develops, problem-solving becomes more effective (expertise reversal effect).

## Sleep and learning

Sleep is not wasted learning time. Memory consolidation happens during sleep.
Studying then sleeping > studying then staying awake.
Naps also consolidate memory — even 20-minute naps show measurable benefits.
