During the last few years enormous research efforts have been dedicated to the developme
7、nt 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; California Virtual University; WIDE University; Ogawa et al., (1999); and DAI-
8、X Web College have been establised. However, in these systems the e-learning completion rate is about 30%. One of the reasons is the low study desire when the learner studies learning materials. Therefore, it is very important to stimulate learners motivation during the study. Recently, several dist
9、ance learning systems that consider the learners capability and understanding have been proposed (Matsumoto et al., 1999; Tamaki et al., 2000; Kuwabara et al., 2000). In Matsumoto et al. (1999), an evaluation system of historical data, based on learning environment and supported by educational softw
10、are record is proposed. In this system, reappearance and analysis are carried out only for historical learning data and not for real education system with individual student advancement control (MESIA). The system is able to keep the teacher operating cost low and to offer fine education by the coop
11、eration of Computer Assisted Instruction (CAI) and teacher. The system is able to recognize the learners who need assistance, but its main purpose is to support the teacher, not the learners.In our previousworks(Koyamaetal.,2001, 2002; Barolli & Koyama, 2004, 2005), we proposed an agent based distan
12、ce learning system to deliver appropriate studying materials to learners and stimulate learners motivation by using mental action of color (Tatsuno, 1995; JCRI, 1993). In order to offer a suitable and efficient study for learners,in this work, we propose a Web-based distance learning system in order
13、 to increase learners efficiency. The proposed system has three subsystems: learning subsystem, learner supporting subsystem and teacher supporting subsystem. The purpose of our system is to increase the e-learning completion rate by stimulating learner motivation. To evaluate the proposed system, w
14、e developed several experiments and surveys. The evaluation shows that by using new features such as: display of learners study history, change of interface color, encourage function, ranking function, self-deter-mination of the study materials, and grouping of learners, the proposed system can incr
15、ease the learning efficiency. The paper is organized as follows. The system structure is introduced in the next section. In Section 3, we present the evaluation method for the proposed system.In Section 4, we discuss the evaluation results. In Section 5, we compare the functions of the proposed syst
16、em with MESIA. Finally, we give some conclusions and future work in Section 6.2 Proposed system structure The proposed system is built on World Wide Web (WWW). In order to have a wide range of applications, we use only standard functions. Therefore, the system can be easily used without depending on the computer environment. The proposed system interface is shown in Fig. 1 and the system structure is shown in Fig. 2. The page output is g
