Highlights
Tier three focuses on personalized, adaptive spaced repetition using algorithms. These algorithms adjust review intervals based on individual understanding and mastery. Examples include dedicated apps like SuperMemo and Anki. The video also touches on custom-built algorithms within note-taking apps, though noting their complexity and potential hassle.
Spaced repetition is introduced as a highly effective learning method, backed by science, that helped the speaker through medical school. It's the opposite of cramming, offering long-term retention benefits. The video promises 11 practical applications and will cover common mistakes to avoid.
Tier one focuses on accessible methods. The first is 'delayed review,' where you allow yourself to partially forget material before reviewing it, increasing retention through effort. An example using a class schedule illustrates how to space out reviews for different subjects over days. The second method, 'interleaving topics,' involves breaking down study blocks for a single day and alternating between subjects to force your brain to retain information more effectively. The third technique is 'end of day review,' which capitalizes on memory decay by reviewing newly learned material at the end of the day to reinforce retention.
Tier two introduces the concept of increasing review intervals. The 'shoebox method' (Leitner system) is presented, using physical boxes to categorize study topics (like flashcards) based on mastery. Correct answers move up a box (less frequent review), and incorrect answers move back to box one (more frequent review). A 'Kanban board' is offered as a digital alternative. The video then discusses 'study timetables,' including prospective (planning reviews ahead of time with increasing intervals like doubling days or using the Fibonacci sequence) and retrospective (tracking reviewed topics and their mastery to prioritize weaker areas) timetables.
Building on retrospective revision, this method applies the concept to individual concepts within a topic. Using an outline or note-taking app, learners can highlight or tag questions/concepts based on their understanding, enabling focused review of weaknesses before tests. This allows for targeted studying based on proficiency.
RemNote is highlighted as a superior solution, integrating spaced repetition algorithms directly into a note-taking app without plugins or coding. It automatically generates spaced repetition flashcards from notes, streamlining the studying process and removing the time-consuming step of transferring notes to flashcards. RemNote offers its own algorithm, the traditional Anki algorithm, or customization options, and is free to use.
The most common mistake is using spaced repetition without active recall. Spaced repetition determines WHEN to study, while active recall dictates HOW to study (e.g., testing yourself). The video emphasizes that these two strategies are complementary and should be combined for optimal learning, such as using retrospective timetables with practice problems or spaced repetition algorithms with flashcards. Viewers are encouraged to watch a companion video on active recall for more methods.
