Experiments of computer supported preparing and performing peer tutoring

Peer tutoring has already been proved to be effective for students´ learning. This paper describes how students, with the support of a prototype system called P³T, learn from peer tutoring in one-on-one computing environment. Collaborative learning is embedded in the designed models. In addition, two experiments were executed in the courses of graduate school, and after valuing the result, we improved this designed system. This paper discusses the design of P³T models and system, and reports on what is found in experiments.
