A web-based e-learning system for increasing study efficiency by stimulating learner’s motivation
Abstract: Due to the opportunities provided by the , more and more people are taking advantage of distance learning courses and during the last few years enormous research efforts have been dedicated to the development of distance learning systems. So far, many e-learning systems are proposed and used practically. However, in these systems the e-pletion rate is about 30%. One of the reasons is the low study desire when the learner studies the learning materials. In this research, we propose an interactive Web-based e-learning system. The purpose of our system is to increase the e-pletion rate by stimulating learner’s motivation. The proposed system has three subsystems: the learning subsystem, learner support subsystem, and teacher support subsystem. The learning subsystem improves the learner’s study desire. The learner support subsystem supports the learner during the study, and the teacher support subsystem supports the teacher to get the learner’s study state. To evaluate the proposed system, we developed several experiments and surveys. By using new features such as: display of learner’s study history, change of interface color, encourage function, ranking function, self-determination of the study materials, and grouping of learners, the proposed system can increase the learning efficiency.

1 Introduction
Due to the opportunities provided by the , more and more people are taking advantage of distance learning courses. During the last few years enormous research efforts have been dedicated to the development of distance learning systems (Nakabayashi et al., 1999; Katayama & Kambayashi, 1999; Ohkawa et al., 2000; Sato et al., 1999). Consequently, many large projects such as CALAT; CALsurf; WebCAI; The University of the Air; Ca
