Carpenter, Pan, and Butler review two well-supported learning strategies: spacing study over time and retrieving information from memory.
Key ideas
Both strengthen long-term learning across ages, content areas, and educational settings, yet learners often underuse them because massed study and rereading feel fluent and produce faster short-term gains. The authors examine mechanisms, boundary conditions, combinations with feedback and elaboration, and evidence from laboratories and classrooms. Spacing requires deciding how learning episodes are distributed; retrieval practice requires attempting recall rather than merely re-exposing oneself to material. Desirable difficulty can make effective study feel less successful while it is occurring, complicating self-regulation.
Why it matters
For educators, the review supports revisiting important ideas after delays, embedding frequent low-stakes recall, varying questions and contexts, correcting errors, and explaining why effortful practice is useful so students can make better independent study decisions.
