Do you want to learn more effectively and efficiently? Do you want to remember what you learn for a long time? If so, you should try spaced repetition, a powerful learning technique that can boost your memory and retention.
Spaced repetition is a method of reviewing and recalling information at optimal intervals until you master it. It is based on the idea that our brains tend to forget information over time, but we can prevent this by repeating the information at the right moments. By doing this, we strengthen our neural connections and make the information more durable and accessible in our memory.
Spaced repetition can help you learn anything, from vocabulary words to historical facts to mathematical formulas. It can also save you time and effort, as you don’t have to review the same information over and over again. Instead, you only review the information when you are about to forget it, which is the most effective way to remember it.

What are the benefits of learning with spaced repetition?
Spaced repetition has many benefits for learning, such as:
- It improves your long-term memory recall. By spacing out your repetitions, you make the information more resistant to forgetting and easier to retrieve when you need it.
- It reduces your cognitive load. By reviewing only the information that is most likely to be forgotten, you avoid overloading your brain with too much information at once.
- It increases your transfer of learning. By reviewing the information in different contexts and formats, you enhance your ability to apply what you learn to new situations and problems.
- It saves your time and energy. By optimizing your review schedule, you reduce the amount of time and effort you spend on studying.
How spaced repetition works and what are the best spacing intervals?
Spaced repetition works by following a simple principle: The more you remember something, the less often you need to review it.
The idea is that every time you review something, you increase its strength in your memory. This means that it will take longer for you to forget it. Therefore, you can increase the time between your reviews without losing the information.
For example, suppose you learn a new word today. You might need to review it tomorrow, then in three days, then in a week, then in a month, then in six months, and so on. Each time you review it, you reinforce its memory trace and make it stronger.
But how do you know when is the best time to review something? How do you avoid reviewing too soon or too late?
There is no definitive answer to this question, as different factors can affect your memory retention, such as your prior knowledge, interest level, difficulty level, and mood. However, there are some general guidelines and formulas that can help you estimate the optimal spacing intervals for your reviews.
One of the most popular formulas is based on the Ebbinghaus forgetting curve, which shows how quickly we forget information over time. According to this formula, the optimal spacing interval (I) for each review (n) is calculated as:
I = I0 * e^(n-1)
where I0 is the initial interval (usually 1 day) and e is a constant factor (usually 2).
For example, using this formula, the optimal spacing intervals for the first five reviews would be:
- Review 1: 1 day
- Review 2: 2 days
- Review 3: 4 days
- Review 4: 8 days
- Review 5: 16 days
Of course, this formula is not perfect and may not suit everyone’s needs and preferences. You may need to adjust it according to your own experience and feedback. The important thing is to find a balance between too much and too little spacing.
How to use spaced repetition tools and apps to study
One of the easiest ways to use spaced repetition for studying is to use tools and apps that automate the process for you. These tools and apps allow you to create flashcards or other types of content that you want to learn and review. They also track your progress and performance and schedule your reviews according to spaced repetition algorithms.
Some of the most popular spaced repetition tools and apps are:
- Anki: A free and open-source flashcard app that lets you create custom decks of cards with text, images, audio, video, or code. You can also download pre-made decks from various topics or share your own decks with others.
- Quizlet: A web-based flashcard app that lets you create or join study sets of cards with text or images. You can also play games or take tests with your cards or join live classes with other learners.
- SuperMemo: A software program that pioneered spaced repetition algorithms and offers various features for creating and managing complex learning projects. You can also access online courses or download pre-made collections from various topics.
- Memrise: A web-based app that lets you learn languages or other subjects using flashcards or videos created by experts or other users. You can also join courses or challenges with other learners or create your own content.
Some tips and tricks to make spaced repetition more fun and effective
Spaced repetition can be a powerful technique for learning anything faster and better. However, it can also be boring or tedious if done incorrectly or without variation. Here are some tips and tricks to make spaced repetition more fun and effective:
- Use different types of content. Don’t limit yourself to flashcards or text-based content. Try using images, audio clips, videos, diagrams, charts, maps, puzzles, quizzes, games, stories, songs, poems, jokes, mnemonics, or anything else that can help you learn better.
- Use different modes of recall. Don’t just read or look at the content. Try recalling it from memory using different modes of recall such as writing it down (or typing), speaking it out loud (or recording), drawing it (or sketching), acting it out (or miming), teaching it (or explaining), or applying it (or solving).
- Use different sources of feedback. Don’t just rely on yourself or the tool/app for feedback. Try getting feedback from different sources such as peers (or classmates), teachers (or tutors), experts (or mentors), books (or articles), podcasts (or videos), blogs (or forums), or social media (or communities).
- Use different contexts of review. Don’t just review in the same place or time every day. Try reviewing in different contexts such as locations (or environments), times (or schedules), moods (or emotions), states (or conditions), goals (or motivations), or perspectives (or angles).
- Use different strategies of review. Don’t just follow a fixed pattern or formula for reviewing. Try using different strategies such as interleaving (mixing up different topics or subjects), elaboration (adding more details or explanations), generation (creating new examples or questions), testing (answering questions or solving problems), or spacing (varying the intervals between reviews).
Conclusion
Spaced repetition is a proven technique that can help you remember what you learn better and longer. By following these steps,
- Know what spaced repetition is and how it works
- Choose a tool or app that suits your needs
- Create content that matches your goals
- Review regularly according to optimal intervals
- Use various tips and tricks to make it more fun and effective
You can use spaced repetition for studying anything faster and better.
