摘要

本研究選擇高中電化學概念為主題，蒐集文獻探討學生常見的另有概念，發展電化學概念教學媒體，做為教學輔助之用，以協助學生建立電化學的微觀世界。
為驗證所發展的教學媒體在協助學生電化學概念的成效，以台北市某公立高中之69名高二升高三的學生為研究樣本，分實驗組與對照組各一班，比較該教學媒體對學生之影響，並對實驗組學生施以問卷調查，了解學生對此種教學的看法。再者，本研究亦想探討老師的教學策略對學生的學習成效。
由研究結果顯示，教學時有使用此教學媒體為輔助的學生的學習成就顯著高於未使用者；並分析不同先備知識學生的學習成效，顯示只有低先備知識的學生經此教學媒體輔助的學習成效顯著高於未使用者。推測低先備知識的學生經具體的呈現概念，較能得到全盤的了解。另外，問卷結果顯示，學生對本教學媒體於學習的幫助給予正面的肯定，也喜歡此種的上課方式，但也建議需在畫面的精緻度與測驗題的數量上做改進，並且需提供講義來輔助教學。 而在教學策略方面，學生對於研究教師給予正面的評價，因此一個優良的教學，應可沿用傳統講述教學法之優點，並結合教學媒體加以輔助，提昇學生學習的成效。

This research chose the concept of high school electrochemistry as the subject. To provide support for education and help students to build up a micro view of the field of electrochemistry by collecting documents in search for students’ misconception, and developing electrochemistry concept learning media.
In order to test the effort of the developed educational media in terms of helping to understand the concepts of electrochemistry, an experiment consisted 69 grade 11 students of a public high school in Taipei were been chosen and divided into one experimental and as well one control group. Comparison among both groups has been made to determine the effect of the educational media, and a questionnaire has been done along with the students from the experimental group to understand students’ opinions on this educational method. Furthermore, this experiment also wishes to investigate the effects on students’ achievement in learning due to instructors’ teaching strategies.
According to the result of the experiment, students who did use this educational media as support, achieve a higher standard compare to those who didn’t. Also, base on the analysis on students of different knowledge background, it appeared that low knowledge background students who did use the educational media, had greater effect in learning achievement. Then, it was to predict that students with low knowledge background would obtain a better result in overall understanding in electrochemistry after receive embodying of basic concepts. Other than that, as for the result of the questionnaire, students gave positive feedbacks towards the educational media for its contribution in learning, and admitted to like this way of lecture; however, suggestions had also been made on improving delicacy of the picture, adjusting amount of testing questions, and providing of the lecture notes to help the lecture.
From the aspect of teaching strategy, students had positive comments toward this research; therefore, it is possible for a good teaching activity to keep the advantages from traditional teaching technique while combining with teaching media to promote students' learing efficiency.
