In this paper, a Moodle-based educational system has been constructed by providing friendly interface to fit most students in e-learning. For the website implementation, the authors take the course "Multimedia Implementation Using JAVA" as a case study. From the modified Moodle-based educational system, the browsing time of each web page for students can be obtained. By analyzing the recorded information, teachers can find out factors which will affect students' learning performance, so as to apply the proposed learning performance evaluation mechanism to evaluate students' learning performance for providing adequate auxiliary learning materials to individual students.
