| Summary: | 碩士 === 淡江大學 === 資訊工程學系 === 88 === Recently, with the rapidly development of the Internet and WWW, Web technologies are used to commerce and education. Distance learning is one of the examples; Current distance learning is mostly based on Web technologies. It improves the traditional teaching method so that it can be suitable for the new trend of education. However, more and more computer — aided learning systems and courseware systems are combined with the hypermedia interface, so the representation of the content of the course is in nonlinear manner and learners can study the content in their favorite order. But the structure of the nonlinear manner which will cause the students to be in navigation missing situations. Moreover, course materials announced as Web documents do not have a normalized structure. It is difficult for students to realize where they are in a Web navigation graph. On the other hand, a textbook has a fixed structure, such as the hierarchy of chapters and the index. A textbook reader knows how to start searching for information with the common structure of books in his/her mind. If distance learning course materials are organized in one or two patterns, it is easier for an individual student to follow. Therefore, We investigate this approach, and propose a system for Web course designs with fixed patterns. This system also makes the learners to construct their knowledge-map learning environment. Through the activities of constructing their knowledge-map, they can organize the fragile knowledge again and prevent them from being missing in their Web navigating process. The “Course pattern” is divided into two parts: Structure pattern and Content template. These two kinds of pattern which have different architectures. The system also serves as a front end module of a Web learning environment which provides automatic assessment of student performance.
