摘要

本研究依據國中三年級理化教材中「認識電解質」與「酸與鹼」兩單元，設計電腦教學媒體，用以探討電腦媒體教學與自我效能兩變項對學生學習成就之影響。以台中縣某私立中學國中部三年級之108位學生為研究樣本，施以前測、教學活動及後測，並利用問卷方式調查受試者的自我效能及學習後感受。研究的結果顯示：
1.前測成績、自我效能及教學方法等變項，均會影響受試者的學習成就。
2.以電腦媒體教學的學習成就較傳統板書教書的學習成就為佳，尤其在「酸與鹼」單元中達顯著差異。
3.不同理化程度之受試者中，以電腦媒體教學的學習成就優於傳統板書教學，尤其中等組在「酸與鹼」單元中達顯著差異。
4.自我效能與學習成就相互影響。高、中效能的受試者以電腦媒體教學之學習成就優於傳統板書教學，尤其是高效能的受試者在「認識電解質」單元中達顯著差異，但低效能的受試者則以傳統板書教學優於電腦媒體教學，尤其是在「認識電解質」單元中的學習成就表現。
5.大部分以電腦媒體教學的受試者對此次的教學活動持肯定的、正面的態度。

The main purpose of this study was to investigate how the learning achievement of Physical Science was influenced by instructional computer medium and self-efficacy. The teaching materials in this study were the units of “to Understand Electrolyte” and “Acids ＆ Bases” in Physical Science Text Books 3. One hundred and eight private ninth grade students sampled from Taichung were enrolled in this study. They were administered pre-test, teaching activities, post-test and self-efficacy scale. The students who were taught by computer medium were asked their opinions about the activities by a questionnaire. The results of this study showed:
1.Learning achievement was influenced by pre-test score, self-efficacy and teaching method.
2.Experimental group had higher learning achievement than control group, especially for the “Acids ＆ Bases” unit.
3.According to different level groups divided by pre-test score, all experimental groups had higher learning achievement than control groups, especially for middle score group, which had significant difference in the “Acids ＆ Bases” unit.
4.Self-efficacy and learning achievement was influenced each other. Students with higher self-efficacy had higher learning achievement, especially for the “to Understand Electrolyte” unit, which had significant difference. As to high and middle self-efficacy groups, experimental groups had higher learning achievement than control groups, especially for high self-efficacy group. But experimental group had lower learning achievement than control group for low self-efficacy group.
5.Most experimental group’s students had positive attitudes toward the teaching activities.
