Evidence-Based Academic Study Methods

Overview

Decades of cognitive psychology research have identified which study techniques reliably improve learning and retention, and which popular methods are largely ineffective. This guide covers the most effective evidence-based strategies — spaced repetition, active recall, interleaving, elaboration, and concrete examples — with practical implementation advice for graduate students and researchers.

Effectiveness Ranking

Based on Dunlosky et al. (2013) comprehensive review of 10 learning techniques:

Core Techniques

1. Active Recall (Practice Testing)

Instead of rereading notes, test yourself:

## Implementation Strategies

Flashcards:
  - Front: Question or concept name
  - Back: Full explanation (not just definition)
  - Tool: Anki (spaced repetition built-in)
  - Rule: If you can explain it without looking, you know it

Blank page method:
  1. Close all materials
  2. Write everything you know about a topic from memory
  3. Open materials and identify gaps
  4. Focus next study session on the gaps

Practice problems:
  - Work through problems WITHOUT looking at solutions first
  - Check solutions only after attempting
  - Struggle is productive — it strengthens memory

Cornell Notes method:
  | Cue Column (30%) | Notes Column (70%)            |
  |-------------------|-------------------------------|
  | Key questions      | Detailed notes from lecture    |
  | After class:       | Cover notes, use cues to recall|
  | Summary section at bottom (written from memory)     |

2. Spaced Repetition

Distribute study over time instead of cramming:

Cramming (massed practice):
  Day 1: Study 4 hours → Exam Day 2 → Forget by Day 10

Spaced practice:
  Day 1: Study 1 hour
  Day 3: Review 30 min
  Day 7: Review 20 min
  Day 14: Review 15 min → Retained for months

Optimal spacing intervals (expanding):
  1st review: 1 day after initial study
  2nd review: 3 days after 1st review
  3rd review: 7 days after 2nd review
  4th review: 21 days after 3rd review
  5th review: 63 days after 4th review

Anki settings for academic material:

Steps: 1 10 (learning steps in minutes)
Graduating interval: 1 day
Easy interval: 4 days
Starting ease: 250%
Maximum interval: 180 days (for course material)
                  365 days (for long-term knowledge)
New cards/day: 20-30 (adjust to workload)

3. Interleaving

Mix different topics or problem types in a single study session:

Blocked practice (less effective):
  Session 1: 20 calculus problems (all integration)
  Session 2: 20 calculus problems (all differentiation)

Interleaved practice (more effective):
  Session 1: Mix of integration, differentiation, and series problems
  Session 2: Same mix in different order

Why: Forces your brain to select the right strategy, not just apply
     the same procedure repeatedly

4. Elaborative Interrogation

Ask "why" and "how" questions while studying:

Instead of:
  "The hippocampus is involved in memory formation."

Ask yourself:
  - WHY is the hippocampus particularly suited for this role?
  - HOW does it interact with the prefrontal cortex?
  - What would happen IF the hippocampus were damaged?
  - How does this RELATE to what I learned about long-term potentiation?
  - Can I think of a CONCRETE EXAMPLE of this process?

5. The Feynman Technique

Step 1: Choose a concept
Step 2: Explain it as if teaching a 12-year-old
  - Use simple language
  - No jargon
  - Draw diagrams
Step 3: Identify gaps (where you stumble or use vague language)
Step 4: Go back to source material for those specific gaps
Step 5: Simplify and refine your explanation
Step 6: Repeat until you can explain it simply and completely

Weekly Study Schedule Template

## Semester Planning

For each course:
  Hours/week = Credit hours × 2-3 (e.g., 3-credit course = 6-9 hours)
  Split: 40% new material, 40% practice/problems, 20% review

## Weekly Template (Graduate Student)

Monday:    [Course A] New material + elaboration notes
Tuesday:   [Course B] New material + elaboration notes
Wednesday: [Course A] Practice problems (interleaved)
           [Course B] Spaced review (Anki)
Thursday:  [Research] Literature reading + annotation
Friday:    [Course B] Practice problems
           [Course A] Spaced review (Anki)
Saturday:  [Research] Writing + data analysis
Sunday:    Rest / light review (Anki only, 15 min)

Reading Academic Papers

## Three-Pass Method (Keshav 2007)

Pass 1 (5-10 min): Skim
  - Title, abstract, introduction, conclusions
  - Section headings and figure captions
  - Decide: relevant? Read further?

Pass 2 (30-60 min): Comprehend
  - Read everything except proofs/details
  - Annotate key claims and evidence
  - Note unfamiliar references to follow up
  - Summarize main contribution in your own words

Pass 3 (2-4 hours): Reproduce
  - Verify every assumption and derivation
  - Mentally re-create the work
  - Identify strengths and weaknesses
  - Note ideas for follow-up research

Exam Preparation

## 2-Week Exam Strategy

Week 2 before:
  - Review all lecture notes (one pass)
  - Create summary sheets per topic
  - Start Anki cards for key concepts
  - Identify weak areas from practice problems

Week 1 before:
  - Focus on weak areas identified
  - Work through past exams under timed conditions
  - Teach concepts to study partner
  - Daily Anki reviews (30 min)

Day before:
  - Light review only (30-60 min)
  - No new material
  - Prepare logistics (location, materials)
  - Sleep ≥ 7 hours (memory consolidation requires sleep)

Exam day:
  - Brief Anki review (10 min)
  - Arrive early, stay calm
