Peer tutoring is a system of instruction in which students help each other and learn by teaching others. Tutors on peer tutoring schemes benefit by reinforcing their fundamental knowledge and developing insight into the learning process. The purpose of this research is to develop a computerized peer tutoring environment in order to support this tuning stage of the tutor's learning process. We propose an integrated intelligent student system (IISS) architecture to overcome some of the difficulties in previous intelligent student systems. A prototype system is built based on our proposed architecture to demonstrate its feasibility.
