Introduction to Spaced Repetition Algorithm

Imagine if your brain had a secret weapon that could supercharge your memory and help you learn Mandarin, including Chinese characters, faster and more effectively. Well, it turns out, it does. It's called the spaced repetition algorithm and it is revolutionizing the way we learn.
Spaced repetition is a proven learning technique that strategically times your study sessions to maximize long-term memory retention. It's a science-backed method that capitalizes on your brain's natural memory processes, making it an invaluable tool for learners grappling with vast amounts of complex material.
At its core, spaced repetition is about the efficient use of your most precious resource - time. Instead of cramming large volumes of information in a short period, this method breaks down your learning into smaller, manageable chunks that are revisited at gradually increasing intervals.
The genius of this method is in the timing. The spaced repetition algorithm predicts the optimum time in the future for you to review a piece of information, just when you're about to forget it. By doing this, it "boosts" your memory, strengthening it each time and making the intervals between reviews longer and longer.
Imagine you're learning Chinese characters with an app like Traverse. The spaced repetition algorithm will show you a new character, say "你" (meaning "you"). After you first learn it, the algorithm will schedule it for review in a day. If you remember it, then the next review might be in three days, then seven days, and so on. Each successful review extends the interval, ensuring the character is etched deeper into your long-term memory with minimal effort.
If you're a lifelong learner looking to supercharge your memory and learn more effectively, the spaced repetition algorithm could be a game-changer. In the following sections, we'll delve into the science behind this fascinating algorithm, explore its applications in language learning, and discover how it's being used in innovative learning platforms like Traverse. So, if you're ready to unlock the power of memory retention, read on!

The Science Behind Spaced Repetition Algorithm

Imagine your brain as a muscular athlete, constantly training to build stronger memory connections. Just like muscles, memories grow stronger with the right kind of exercise. The spaced repetition algorithm is the brain's personal trainer, optimizing your study schedule for peak performance.

The Forgetting Curve and Spaced Repetition

Did you know that forgetting is actually beneficial for learning? Paradoxical as it may sound, the natural process of forgetting helps fine-tune our memory. According to the "Forget to Learn" theory, our brains store memories with two strengths: storage strength, which remains steady, and retrieval strength, which fades over time. As retrieval strength drops, learning increases when we access the memory again. This phenomenon, known as desirable difficulty, is a key reason why spaced repetition works so well.
The spaced repetition algorithm uses the concept of the "forgetting curve" to its advantage. It schedules your study sessions just as your memory of the material is about to fade. Each review resets the forgetting curve and strengthens your memory. Simply put, the algorithm ensures you review the material just before you forget it, thereby slowing down the decay of your memory. This strategy of repeating the information at increasing intervals makes the forgetting curve flat, enabling longer retention of the information.

Cognitive Science Research Supporting Spaced Repetition

The effectiveness of spaced repetition is not just a theory, it's a scientific fact. The concept of spaced repetition was first proposed in 1932 by Prof. C. A. Mace in his book Psychology of Study. Its efficacy was later demonstrated by H. F. Spitzer in 1939, who showed spaced repetition significantly improved the learning of science facts by sixth-grade students.
Further research has shown that spaced repetition leverages two key principles from cognitive science. The first is the testing effect, also known as 'active recall', which asserts that actively testing yourself on a piece of knowledge is more effective than passively re-reading it. A meta-analysis of 118 studies found this effect to be 51% more effective compared to passive re-reading, and 93% more effective compared to 'doing nothing'.
The second principle is the spacing effect, which advocates for spacing out study sessions over multiple periods (spaced practice), as opposed to cramming everything at once (massed practice). Spaced repetition enhances this effect by determining the optimal spacing intervals for maximum retention.
As a lifelong learner, understanding the science behind the spaced repetition algorithm can empower you to take control of your learning journey. Whether you're mastering Mandarin or pursuing a passion for physics, this approach offers an efficient path to long-term knowledge retention. Stay tuned to discover how this algorithm is being applied in language learning, especially in the fascinating world of Chinese characters.

Understanding Anki's Spaced Repetition Algorithm

Anki's Algorithm Based on SuperMemo 2

Imagine having a personal assistant who understands your memory strengths and weaknesses and optimizes your study schedule accordingly. That's essentially what Anki's spaced repetition algorithm does. Anki's algorithm is a digital variant of the SuperMemo 2 (SM-2) algorithm, an early iteration of the SuperMemo family of algorithms designed to optimize learning efficiency.

Key Differences Between Anki's Algorithm and SuperMemo 2

While Anki's algorithm owes its roots to SM-2, it's not a carbon copy of its predecessor. There are a few key differences worth noting. First, SM-2 prescribes an initial interval of 1 day then 6 days, while Anki offers users full control over the initial learning steps. This flexibility is crucial in acknowledging that every learner is different, and what works for one person might not work for another.
Secondly, Anki simplifies the answering process. Instead of six choices for answering review cards in SM-2, Anki uses only four. This change is based on the understanding that failure comprises a small number of total reviews and thus, adjusting a card's ease can be sufficiently done by varying the positive answers.
Finally, Anki factors in tardiness in answering cards into the next interval calculation. So if you remember a card even though you answered it later than scheduled, the algorithm gives you a memory "boost".

How Anki's Algorithm Works: Learning, Reviewing, and Scheduling

Anki's algorithm takes a three-pronged approach: learning, reviewing, and scheduling.
During the learning stage, Anki understands that it can take several encounters with a new card before you're able to memorize it. If you fail to recall a card, it doesn't mean you need to be punished by being shown the failed card many times over a few days. Performance during the learning stage doesn't reflect performance in the retention stage.
When it comes to reviewing, the algorithm uses your performance to adjust the card's ease. This process is streamlined through the use of four answer choices, not six as in SM-2. Anki provides only one fail choice, not three, simplifying the process and targeting your learning more effectively.
Lastly, the scheduling component of Anki's algorithm calculates the next review interval based on your past performance, including if you were late in answering but still remembered the card.
In essence, Anki's spaced repetition algorithm is a powerful tool tailored to individual learning needs. It's like having a personal learning coach, making the daunting task of memorizing Chinese characters or any other complex concepts manageable and efficient.
