主要目的在探討電腦影像示範教學在合作學習情境下不同性別對舞蹈動作技能之學習成效。本研究以大專學生共4班120爲實驗對象，以前測成績區分爲男生或女生學生，受試者完成合作學習訓練後，並以隨機方式指派受試者進入不同組別進行實驗。受試者完成教學實驗課程後，立即接受學習成效測驗。本研究結果指出：在合作學習情境下的學習效果，比單獨一人的學習更好。學生無論是在教師示範或電腦視覺影像示範的教學模式下，皆比沒有示範教學模式下更有效益。對男生而言，接受教師示範模式教學課程之後在學習成效方面顯著的高於那些電腦視覺示範模式與無任何示範模式的學生。然而，對女生而言，在教師示範模式與視覺示範模式兩者並無顯著的差異。最後，本研究發現電腦視覺示範的教學模式與合作學習對大專舞蹈課程的學習是一條有效的途徑，可供未來運動教育之參考。

The purpose of the study was to examine effect of video modeling on college lessons in a cooperative learning environment. The learning effect of computer image demonstration teaching to the dance skills learning of students of different genders in a cooperative learning environment. The study takes 120 college students from 4 classes as experimental subjects, using previous test scores to divide them into boy students and girl students. After participants finished cooperative learning and training, they were assigned at random to different groups to have the experiment. After finishing the experimental teaching lessons, they received a test on their learning effect immediately. The results of the study show that the learning effect in the environment of cooperative learning is better than studying alone. Both of the teaching mode of the demonstration given by teachers and the mode of computer visual image have better effect than that of no demonstration. For boy students, after they received the teaching lessons of the mode of teachers' demonstration, it is obvious that they got better learning effect than those who only received the mode of computer visual image demonstration and those who received neither of the two modes above. However, for girl students, there is no obvious difference between the mode of teachers' demonstration and the mode of computer visual image demonstration. Finally, the study found that the combination of the mode of computer visual image demonstration with the mode of cooperative learning is an effective way for the learning of college dance lessons, which can be a reference for future sport education.
