摘要
构建以知识结构为基础的信息技术化适性诊断系统。在研究过程中,先以专家知识结构出题,每个试题皆让100位以上的学生预先测试,分析学生的知识结构,系统以此学生知识结构出题,并于学生作答完毕后加以诊断,提供学习诊断报告。最后以专家知识结构结合学生知识结构的补教教学结构进行补充学习,达到因材施测与因材施教的目标。研究发现,该系统具有节省试题、缩短施测时间及高预测率的功效。
The paper establishes the computerized adaptive diagnosis testing system based on knowledge structure. Firstly, it designs questions according to the experts＇ knowledge structure, each question put into the pretests with the sample size of more than 100 students, and analyzes students＇ knowledge structure.According to students＇ knowledge structure, the system designs the questions, diagnoses the answers and provides the learning diagnosis report. Finally, combined experts＇ knowledge structure with students＇ knowledge structure, it obtains the remedial teaching structure in order to teach and test students in accordance of their aptitude.The research shows that the system has characteristics of saving questions, shortening testing time and high prediction rate.
