| Summary: | 碩士 === 中原大學 === 資訊工程研究所 === 96 === The e-learning is more and more convenient for collecting information and developing the multimedia teaching material by developing of information technology and World-Wide Web. But increasing the learning efficiency is still an important issue in e-learning.
Nowadays, Problem-Based Learning becomes a teaching tendency. By Problem-Based Learning, the student solves the problem which teacher proposed, achieves the studying effect. In Problem-Based Learning, student reorganizes his materials that are collected by discussion with others on concept map. Concept map can make these data that are collected by student visualizable.
Students can compare the concept map made by themselves with others and they can know the difference from concept map. Teacher can find the erroneous concepts or short of concepts by detecting student's concept map and teacher can help student to fix the concept by these erroneous concepts or short of concepts.
Knowledge map is another knowledge structure like concept map. It is composed of concept hierarchy and concept schema. Concept hierarchy is like concept map. Concept in the concept map is unique and there is not the same concept. But concept can be the same in knowledge map. The same concept has different meanings in different place or containing different concept schemas.
In this thesis, we try to make a quantitative method for knowledge map by using concept map's quantitative method. The feedback system can cut a knowledge map into several different blocks, and teacher can know the student's knowledge structure by cutting these several blocks. We design a real time detection system that can detect the attributes of knowledge map. By detecting the attributes of knowledge map, teacher can find the key point about the student's discussion easily.
