Using Spacing to Promote Lasting Learning in Educational Contexts

Abstract

Abstract. Spacing repeated study phases across multiple sessions instead of studying and restudying the learning material in one session only is an effective strategy to promote lasting learning. However, most studies demonstrating the spacing effect were conducted in the laboratory, using simple verbal material. Learning in educational contexts differs regarding the complexity and coherence of the learning material and concerning the role of motivational and affective learner characteristics. Studies conducted in educational contexts suggest that the spacing effect is not as robust here. For example, acquiring mathematical skills or nonrepeated, consecutive information does not reliably benefit from spacing. After an overview of studies addressing the spacing effect in the laboratory and in educational contexts, we discuss various open questions that need to be addressed by future research before recommending spacing as a learning strategy to promote meaningful and lasting learning at schools and universities.
