Spaced Repetition is a learning technique that involves reviewing information at increasing intervals over time. This method helps reinforce memory retention by taking advantage of the brain's natural forgetting curve, which suggests that we forget information more quickly shortly after learning it. By revisiting material just before we are likely to forget it, we strengthen our recall and understanding. This technique is often used in language learning and studying for exams. Tools like flashcards and software applications, such as Anki, utilize spaced repetition algorithms to optimize review schedules, making learning more efficient and effective.
