Building an Object-Oriented and Individualized Learning Environment on the WWW
The web-based educational systems are becoming more and more popular around the world. Several approaches, which are used to organize the teaching materials appropriately, have been developed in the past ten years . One of them is just putting all of teaching materials on the web looked just like an electronic book although some friendly user interface or interesting multimedia has been added . Others are adding an evaluation mechanism into system which works at the end of each section of course materials to find out what instructional objectives the students do not learned well . According to these evaluation results, the system can offer the remedial teaching materials properly for students to learn again. However, in above two approaches, the students always need to learn all teaching materials at least once no matter how the teaching materials are suitable for them or not when they enter a new section. Therefore, we are interested in developing a tutoring system which can offer different teaching materials for different students in accordance with their aptitude. In order to achieve this goal, both the teaching materials and the students’ profiles should have some attributes and then system can construct different course frameworks for different students accordingly, where the “course framework” in this thesis is defined as the arrangement and representation of teaching materials. However, as shown in Fig. 1.1, the traditional course model usually arranges the teaching materials in sequential and monotonous way. It means that the course framework offered for the students are the same regardless of offering the individualized course framework in accordance with student’s aptitude.
