Meta-analysis of 64 studies involving 6000 participants finds that self-explanation is a powerful learning technique

07 December 2018

It is better to ask a student to explain something to themselves, than for a teacher to explain it to them.

That’s according to a new meta-analysis of the findings from 64 prior studies involving nearly 6000 participants that compared learning outcomes from prompted self-explanation compared to instructor explanation, or compared to time spent using other study techniques such as taking notes, summarising, thinking out loud (without the reflection and elaboration involved in self-explanation), or solving more problems.

The authors of the meta-analysis, published recently in Educational Psychology Review, say that self-explanation is a powerful learning strategy because learners “generate inferences about causal connections and conceptual relationships that enhance understanding”.

The process of self-explanation also helps the learner realise what they don’t know, “to fill in missing information, monitor understanding, and modify fusions of new information with prior knowledge when discrepancies or deficiencies are detected”.
