摘要 本研究結合教授及數學科教師的意見,目的在建立以貝氏網路為基礎的電腦診斷測驗及動畫補救教學系統。提供學生在進行電腦診斷測驗後,能依其錯誤類型,即時進行電腦動畫補救教學。 本系統利用電腦來進行學生錯誤類型的分析,除了讓學生了解自我學習狀況,進而運用程式所提供補救的教學達到自學的效果之外,更希望能讓教師迅速了解學生學習問題所在,改進教學的方式及技巧。不再需要花太多的時間去診斷及進行補救教學,減輕教師的工作負擔,讓教與學都能發揮最大的成效。 本研究達成的成果如下: 一、運用貝氏網路模式,對學生的錯誤類型與能力指標的辨識率有很好的效果。 二、電腦化適性補救教學確可達到補救教學的效果。 關鍵字:貝氏網路、補救教學、數與量、能力指標
Abstract This paper integrates the opinions of the professors and mathematical teachers, the purpose is setting up a computerized diagnosing test and animated remedial instruction system, providing the student after computerized diagnosing test, according to the analysis of its mistake type, carry on the adaptability, immediately remediable teaching. In this system, we used the computer to analysis students’ mistake types. We hope to make students understand their own study problems, and then use the remedial instruction of computer procedure to improve their learning. So the system is used to assist teachers and students in evaluating and exploring the students’ learning process and outcomes. The results are as follows: 1. The results show that using Bayesian networks to diagnose the existence of mistake types and sub-skills in individual students can get good performance. 2. The progress of students are significant after taking the adaptive remedial instruction. Key words: Bayesian Networks, remedial instruction, figures and quantity, competence indicators.
