中文摘要 本研究以國小三年級數學「量與實測」的能力指標為依據,目的在建立以貝氏網路為基礎的電腦診斷測驗及適性動畫補救教學系統。提供學生在進行電腦診斷測驗後,能依其錯誤類型,即時進行適性補救教學。 有別於傳統的診斷分析,既費時又費力。本系統嘗試利用電腦來進行學生錯誤類型的分析,並對個別學生進行補救教學,因材施教,以減輕教師教學與評量的負擔,提升學習成效。 本研究結果發現: 一、編製的試題能鑑別學生能力指標達成度且適用電腦化診斷測驗系統。 二、以貝氏網路模型為推論工具,用於診斷國小三年級學生「量與實測」錯誤類型具可行性。 三、所建置之動畫補救教學系統和線上測驗連成一貫,可提供及時、適性的學習。 四、補救教學模組無論在全體受測學生或高分組、低分組學生上,均有顯著進步的表現。 關鍵字:電腦化診斷測驗、貝氏網路、錯誤類型、補救教學、量與實測
Abstract The main idea of the study is to establish the suitable remedy instructions program based on Bayesian Networks and the ability index of Quanity and Measurement on Grade 3. It can offer the real time remedy instructions by the mistaken types after taking the test online. It is time consuming to take the traditional paper test. According to the weakness, the program is designed to analyze the mistaken types and gives individual remedy instructions based on different talent. It can also reduce the teachers’ loading and improve the studying effective. There are four conclusions as below. 1. The designed question in the program can make the differentiation of the students’ ability index. 2. It is workable to diagnose the mistaken types of Quanity and Measurement index on Grade 3 by the program. 3. The test result online can feedback to the program, offer real time and suitable remedy instructions. 4. All of the students with different levels get obviously improvement by using the program. Keywords : Computerized Diagnose test, Bayesian Networks, Bug Type, Remedy Instructions, Quanity and Measurement
