摘要

本研究旨在應用概念圖策略融入教學，探討化學平衡中抽象且易造成概念迷思及誤解的勒沙特列原理概念和數的學習效益。運用準實驗研究法進行分組教學，並以大一選修化學課程之學生112位做為研究對象，為期3週實驗教學。資料處理採one-wayANCOVA方法，並輔以對學生之深度訪談。研究結果顯示：(一)實驗組學生化學平衡學習成就與學後保留成績，顯著優於控制組。(二)實驗組策略教學可同時提昇學生化學平衡概念與數的有效學習。(三)本研究發展之教材能引起學生正面且積極的學習態度。(四)高分組學生認為策略教學有助於概念的釐清與解題能力提昇，低分組學生則期待未來能有更加簡易實用的概念圖策略設計。

The purpose of this study was to explore strategic applications of concept maps in the chemistry equilibrium of comprehensive Le Chatelier's Principle to solve students' chemical misconceptions. An assessment of quasi-experimental approach was adopted for the efficiency of strategic instructions on students' learning. There were 112 engineering class students who took this chemical course as research participant groups, one class as the experimental group and the other as control group in the time intervention of three weeks. All data analyses were collected with the one-way ANCOVA of students' learning performances, together with semi-structure interviews as major research instruments. All research results would be summarized in the following way: (1) Experimental group students had better posttest and learning retention achievements than those of controlling group students. (2) Statistical results indicated the same experimental group students could promote their learning achievements in chemical equilibrium concepts and algorithms than those of controlling group students in contrasts of posttests and pretests grades. (3) The strategic instructions of this study could attract experimental group students' positive learning attitude. (4) According to semi-structure interview results between students, all strategic applications of chemical equilibrium had much appeal to high score students' curiosity and interests for learning performances and problem-solving skills, and the same joyful expectation to low score students for easy-to-take applications of concept maps and integrated animations in the future.
