碩士 === 輔仁大學 === 應用統計學研究所 === 96 === Based on the Evidence-Centered Design（ECD）structure and Bayesian Networks ,a system with a computerized adaptive diagnostic testing and a computerized adaptive remedial instruction were developed using "the fraction addition and subtraction" as an example . With this system students could receive not only individual diagnostic tests, but adequate and in-time computerized adaptive remedial instruction .Hopefully evaluation diagnosis and remedial could be achieved simultaneously. The conclusion of the research is as follows: 1.The results showed that using Bayesian networks to diagnose the existence of mistake types and sub-skills in individual students could have good effects. 2.Both testing and remedial teaching can be achieved simultaneously. 3.The progress of students were significant after taking the adaptive remedial instruction.
