Abstract

In Experiment 1, According to the type of utterance, experiment conditions were divided into the Read-Aloud group, the Self^Explanation group, and the Explaining to Others(teach) group. After finishing the task, each participant of group was given a recognition, recall, and drawing test. The Explaining to Others(Teach) group was better than the other groups in all tests. In experiment 2, the Explaining to Others group was subdivided into the Face to Face and the CMC(Computer Mediated Communication) group to study the effects of explanation depending on the type of an explainee. The result indicated that the experience of explanation was of benefit to the declarative knowledge acquisition. In addition, it was discussed that no difference in the Face to Face condition and CMC condition was due to the trade-offs of situational characteristics.
