摘要

本研究中，研究者結合奧斯貝的有意義學習理論與專家概念圖而發展出一套「氧化還原反應」電腦輔助學習軟體。本研究的目的在探討此套電腦輔助學習軟體能否幫助學生達到有意義之學習。
本研究選取研究者所任教的九十二位高三學生（男生73位，女生19位）進行本軟體的上機學習。資料來源包括三次筆測驗（前測、後測與延宕後測）、半結構性晤談性、感受問卷以及現場札記，由三次測驗的成績與各題選項的選答情形來探討本軟體的成敦以及學生常發生的另有概念，再從後測成績中挑選進步顯著與不顯著的學生共十位（男生6位，女生4位）進行半結構性晤談，以瞭解學生的概念改變情形。
由資料分析結果，提出以下四點結論：
１.本軟體可以有效提升學生的學習成效。
２.本軟體可幫助學生正確地連結相關概念。
３.本軟體可有效幫助學生產生概念改變。
４.學生表現出高度的學習興致與主動而積極的學習態度。

This study was to develop a computer-assisted learning (CAL) software which was based on Ausubel’s meaningful learning theory and experts’ concept map and to study the meaningful learning of students through using this software.
The subjects of this research were ninety-two K-12 students (73 males and 19 females) who had earlier been taught the topic of “Oxidation-Reduction Reactions” by the researcher. The Data collected included pre-test, post-test, delay post-test and semi-constructed interview. Four conclusions were found in this study as following:
(1).This software was able to enhance the achievement of students effectively.
(2).This software could help students to connect related concepts of “Oxidation-Reduction Reaction” correctly.
(3).This software could help students to make changes of concepts effectively.
(4).The students showed highly interest in using this software.
