Project description

Learning by explaining (to fictitious others) can be regarded as an effective instructional method to support students’ deep processing. In this research project, we investigated individual and instructional boundary conditions of learning by explaining in schooling and higher education. Furthermore, we examined whether and how explaining can be supported by educational technology.


Learning by explaining to fictitious others is a consolidating learning strategy to scaffold students’ deep-processing. Students first learn the contents of new material and are then required to explain the previously learned content to (fictitious) persons (e.g. in the format of a video). By generating an explanation, new information should be related to one’s prior knowledge and result in a deep understanding of the learning material. However, it is not yet clear how such explanatory activities should be designed and supported to promote deep-learning processes.
Against this background, we conducted several experimental studies to examine how learning by explanation can be made effective. For instance, we investigated effects of explanatory modality (written versus oral) or the timing of explaining on students’ learning gains. Additionally, we investigated, how explaining can be supported by computer-based feedback. The findings were replicated in natural field studies in teaching and university settings.
