Key points

  • Active recall, also called practice testing, is presented as the most effective revision strategy because retrieving facts from memory strengthens learning.
  • Rereading is described as a common but low-utility study method that is less effective than other approaches.
  • Highlighting is popular but mostly ineffective, and it can hinder performance on tasks that require inference.
  • Summarising has mixed evidence and is usually only helpful for students who are already skilled at doing it well.
  • The video cites studies showing practice testing can improve exam scores more than re-studying with rereading, highlighting, or summarising.
  • Practical active recall methods in the video include Anki flashcards, closed-book spider diagrams, and turning notes into questions.

1. Popular but inefficient technique #1 - Rereading 1m29s

  • Rereading is a common revision technique among students.
  • Studies indicate that rereading has low utility in terms of exam preparation strategy.
  • Compared to other techniques, rereading is less effective.
  • Professor John Dunlosky rated rereading as having low utility based on extensive research.

2. Popular but inefficient technique #2 - Highlighting 3m29s

  • Highlighting is very popular but mostly ineffective.
  • Evidence suggests it has low utility and can hinder performance on tasks requiring inference making.
  • Highlighting could be useful if students know how to use it effectively.
  • It is often used despite its proven limited effectiveness.

3. Popular but inefficient technique #3 - Summarising 4m51s

  • Summarising is widely used but the evidence of its effectiveness is mixed.
  • It may be beneficial for those already skilled at summarising but is otherwise of low utility.
  • Most learners need extensive training to summarise effectively, reducing its feasibility.
  • In comparison to other techniques, summarising is not the most efficient.

4. Active Recall, and the evidence behind why it's the most effective revision strategy 6m42s

  • Active Recall or practice testing is highly effective and has high utility.
  • The technique involves retrieving facts from memory, which strengthens neural connections.
  • Professor Dunlosky's review paper endorses practice testing as a form of revision with significant positive impact.
  • It's recommended to implement Active Recall in study routines for efficiency.

5. Study #1 - Spitzer 1939 9m18s & 6. Study #2 - Butler 2010 10m22s

  • A study from 1939 showed that practice testing led to a 10-15% improvement in student scores.
  • A 2010 study found that practice testing yielded up to a 30% improvement in exam scores over re-studying material using common techniques like rereading, highlighting, and summarising.
  • Both studies support the effectiveness of practice testing over traditional study methods.

7..Study #3 - Karpicke & Blunt 2011 11m16s

  • Conducted with students split into four groups to study material and test a week later.
  • Group 1 studied the text once, Group 2 four times, Group 3 created a mind map after one study, Group 4 practiced recalling as much as possible after one study.
  • On verbatim questions, Group 4 (active recall) performed significantly better than Group 2 (studied four times).
  • On inference questions, Group 4 also performed the best, indicating active recall's effectiveness over repeated study.
  • Before the experiment, students predicted that repeated study would be most effective, showing a mismatch between intuition and evidence.
  • The evidence suggests active recall is more efficient than strategies like repeated reading.

8..Specific, practical strategies for incorporating Active Recall into your revision / study routine. 13m41s

9..Strategy #1 - Anki flashcards 14m19s

  • Anki is advocated for memorizing facts; ratings of easy, medium, or hard determine when cards will reappear.
  • Users can use Anki to memorize specific details, facts, or essays for exams.
  • Anki's algorithm adapts over time and assists with spaced repetition for efficient studying.
  • The app is free, and there's an optional paid iOS version.

10..Strategy #2 - Closed-book spider diagrams 16m7s

  • The technique involves writing down everything remembered about a topic after studying, without the book open.
  • After creating a spider diagram from memory, the book is reopened to identify any missing information.
  • This method of active recall, combined with spaced repetition, led to excellent exam performance.

11..Strategy #3 - Questions instead of notes, the Cornell note-taking system 17m33s

  • A shift from note-taking to writing questions that prompt active recall of lecture or textbook material.
  • The question-based revision technique is said to be effective in enhancing memory and understanding.
  • One anecdote cites a student who succeeded in exams by solely revising through self-written questions.

Active recall revision is a study method where you try to retrieve information from memory instead of just rereading it. The video presents it as practice testing, and says it is more effective than common techniques like rereading, highlighting, and summarising because retrieval strengthens learning.
