Kartei

Kartei refers to a specific method of spaced repetition learning. It is a system designed to help individuals memorize information more effectively by reviewing material at increasing intervals. The core principle behind Kartei is that revisiting information just as you are about to forget it strengthens your memory of that information.

The traditional Kartei system involves a set of cards, often referred to as flashcards. Each card contains a question or prompt on one side and the corresponding answer or information on the other. When a learner reviews a card, they assess their recall. If they answer correctly, the card is moved to a further spaced interval for review. If they answer incorrectly, the card is moved back to an earlier interval, requiring more frequent review. This process continues until the learner can reliably recall the information at the desired interval.

While originally conceived as a physical card system, the principles of Kartei have been widely adopted in digital flashcard applications and spaced repetition software. These digital tools automate the scheduling of reviews, making the process more efficient and adaptable. The effectiveness of Kartei lies in its systematic approach to combating the forgetting curve, ensuring that learned material is retained in long-term memory. It is commonly used for learning languages, facts, vocabulary, and any subject matter that requires memorization.
