本研究主要在研發一套以國小五年級數學領域「小數的加減」單元為內容的以知識結構為基礎之數位個別指導教材及電腦適性測驗,使教師在進行教學指導後,有相對應的適性測驗能實施,期能達到「因材施教」與「因材施測」的效果。研究結果摘述如下: 一、「小數的加減」單元之電腦適性測驗的平均施測題數是18.5題,平均可以節省11.5題,可達92.96%~97.26%的精確預測度。 二、使用「小數的加減」單元之數位個別指導教材進行教學及補救教學後,將學生的表現依起點行為與前測、前測與後測兩相比較,皆有顯著的進步,表示此套數位個別指導教材有其教學成效及使用價值。 三、使用此套教材進行個別指導及團班教學,學生的成績都有顯著進步,尤以接受個別指導之學生進步較多,可見此套以知識結構為基礎編製的數位個別指導教材不僅適用於不同教學模式,用於個別指導模式會有更大的功效。 四、以性別而言,接受個別指導之男生進步最多;以能力分組而言,中分組及低分組的進步分數優於高分組,且中分組及低分組的表現是個別指導優於團班教學。
This study aims to develop a knowledge structure based digital individual learning content and computerized adaptive testing(BNAT) which is about addition and subtraction on decimals in the Fifth Grade. It lets teachers have adaptable adaptive testing after teaching. We hope it can reach significant effect on meeting students’ individual needs and testing students’ individual abilities.Results: 1. The number of items administrated by BNAT is 18.5. 11.5 items are omitted and prediction accuracy can reach 92.96%~97.26%. 2. After the teaching and adaptively remedial instruction with digital individual learning content, students have significant progress on their grades. It shows that this digital individual learning content is valuable for using. 3. This digital individual learning content is adaptable to two kinds of teaching models, and the study shows that individual instruction will have great effect. 4. In point of the sex, the boys taught by the teaching model of individual instruction have the greatest progress. In point of the student’s ability, the students of the middle mark group and the low mark group get more grades than the high mark group. Bye the way, taking individual teaching is better than group teaching among the middle mark group and the low mark group.
