Outline of Final Research Achievements

For promoting students’ conceptual understanding of mechanics, a system was developed and empirically evaluated that adaptively sequences problems and explains the difference between them with a framework for indexing physical models based on their assumptions. We (1) systematized the concepts for explanation, (2) implemented an explanation generator and integrated it into the previously developed system that can adaptively sequence problems, and (3) validated its effectiveness in learning mechanics and analyzed students’ learning process through experiments. Consequently, this research clarified the fact that explanations by the system promoted students’ conceptual understanding, and the cognitive model about the factors that promote students’ learning under various conditions.
