Learning that is spread out over time drastically increases knowledge retention.

A report found that assessing one's own knowledge before an exam, through self quizzes and summaries of the core content, can improve a student's overall performance.Multiple studies have also found that micro-learning can deter cognitive overload, which occurs when the brain is forced to accept an abundance of data at any given time. Therefore, designing eLearning courses, which are geared toward delivering bite size chunks of knowledge at once, such as in shorter eLearning modules, can lead to more effective online learning (Chunking Strategies).
