Based on the theoretical framework： social cognitive theory and constructivism, on-line peer assessment enhances interaction and improvement. The result comes up with the conclusion that this way of assessment is effective, especially for Chinese students, to improve efficacy, to develop confidence in oral presentation, and to foster autonomy in learning展开更多
