Easy learn Flash Card 对比 Flashcard English for beginner 的使用情况和统计数据

Easy learn is a free app to learn English fast and easy via Leitner system , The Leitner system is a widely used method of efficiently using flashcards that was proposed by the German science journalist Sebastian Leitner in the 1970s. It is a simple implementation of the principle of spaced repetition, where cards are reviewed at increasing intervals. You can learn : English to English , English to Arabic as well . In this method, flashcards are sorted into groups according to how well the learner knows each one in Leitner's learning box. The learners try to recall the solution written on a flashcard. If they succeed, they send the card to the next group. If they fail, they send it back to the first group. Each succeeding group has a longer period before the learner is required to revisit the cards. In Leitner's original method, published in his book So lernt man Lernen (How to learn to learn), the schedule of repetition was governed by the size of the partitions in the learning box. These were 1, 2, 5, 8, and 14cm. Only when a partition became full was the learner to review some of the cards it contained, moving them forward or back depending on whether they remembered them.
