Human memory is imperfect; thus, periodic review is required for the long-term preservation of knowledge and skills. However, students at every educational level are challenged by an ever-growing amount of material to review and an ongoing imperative to master new material. We developed a method for efficient, systematic, personalized review that combines statistical techniques for inferring individual differences with a psychological theory of memory. The method was integrated into a semester-long middle-school foreign-language course via retrieval-practice software. Using a cumulative exam administered after the semester's end, we compared time-matched review strategies and found that personalized review yielded a 16.5% boost in course retention over current educational practice (massed study) and a 10.0% improvement over a one-size-fits-all strategy for spaced study.
人类的记忆并不完美；因此，为了长期保存知识和技能，需要定期复习。然而，各个教育阶段的学生都面临着越来越多的需要复习的材料，以及不断掌握新材料的要求。我们开发了一种高效、系统、个性化的复习方法，该方法结合了用于推断个体差异的统计技术和记忆的心理学理论。该方法通过检索实践软件整合到了一个为期一学期的中学外语课程中。使用学期结束后进行的累积考试，我们比较了时间匹配的复习策略，发现个性化复习比当前的教育实践（集中学习）提高了 16.5%的课程保留率，比统一的间隔学习策略提高了 10.0%。
