Active Recall and Spaced Repetition

Recall utilizes two scientifically proven learning techniques, Active Recall and Spaced Repetition, to enhance information retention for the content that you save to your knowledge base. This system prompts you with questions generated from your saved content, following a schedule that optimizes memory strength over time.

What is Active Recall?

Active Recall is a learning method where you try to remember information without referencing the material. This technique has been shown to significantly enhance long-term retention compared to passive reading. Actively retrieving information helps strengthen neural pathways, thereby improving recall and promoting the transfer of knowledge to long-term memory.

What is Spaced Repetition?

Spaced Repetition involves reviewing information at progressively increasing intervals. This method leverages the psychological spacing effect, where revisiting material just before it is forgotten enhances memory retention. By strategically timing reviews, Spaced Repetition helps cement information in memory.

How Recall Implements These Techniques

A single card review

To generate questions for a knowledge card and add it to your Recall Review:

1. Click the Quiz Tab on the card you want to review.
2. Select Generate Questions to create quiz questions that will be added to your Recall Review Queue.
3. Clicking Review Now to quiz yourself on just this card.
4. Manage Questions by generating more, adding your own, or edit/delete existing ones.

Your spaced repetition schedule

Start your Recall Review by clicking the Review icon (top-left of the screen). Here you can see which cards have questions in your next review, track your progress and manage your questions.

Simply click Start Review to begin your spaced repetition session.

The Review Schedule

An important aspect of a spaced repetition system is the review schedule that determines the frequency that you are presented with questions. Questions are scheduled for review at specific intervals to reinforce the learning curve and solidify information in long-term memory.

In Recall, the review schedule is as follows:

• Immediate Review: When the questions are generated they are scheduled for review immediately.
• Subsequent Reviews: Provided you get the questions correct, the subsequent reviews are scheduled for 7 days, 30 days, and 6 months post each correct response.
• Incorrect Responses: Questions answered incorrectly are rescheduled for review the next day regardless of where they currently are in the review schedule.

Each review phase is designed to reinforce the learning curve and aid in solidifying information in long-term memory.
