但是，在電腦化教學的現代，在電腦上繪製概念圖來評量卻有著一個問題，就是協助評分機制的不足，許多概念圖繪製的系統只能提供學生繪製，卻沒有協助教師有效分析學生概念圖的功能，所以在本研究中設計了一個客製化的概念圖評量系統和概念圖評分機制，讓老師可以透過這個系統開發不同課程的概念圖評量機制讓學生評量，系統會對於學生所繪製出來的概念圖會加以分析和評分，提供給教師做為了解學生學習程度和認知方向是否錯誤的依據，在接下來的教學活動中可以進行修正和補充。 A knowledge map is a structural representation, which is consisted of nodes and links. Each node represents a concept in the domain of knowledge. Each link, which connects two nodes, is used to represent the relationship between them; that is, the relationship between the two concepts. Previous literature has shown its validity and reliability of assessing content understanding. But there is lack of computer-based customized-able content understanding assessment system with scoring function. The purpose of this research is to design a feasible content understanding assessment system. The teacher can use the Authoring tool to design the concept map assessment course for different content Then let student use it , The system will analyze and scoring the concept map which make by students ,These information will provide to teacher to understand the content understanding and learning direction of the students , Then revision the teaching strategy in the future.
