The purpose of this study was to explore the differences between the conventional teaching and virtual reality assisted basketball teaching, on attitude toward physical education, cognition and game performance for Junior High school students. Method: The experiment was conducted in the physical education courses in one Junior High school of New Taipei City .The participants were 8th graders with total number of 55 (n=55) from two classes. Participants were assigned to control group and experimental group. Participants in the experimental group were taught with virtual reality (N=27) and Participants in the control group were with conventional teaching methods (N=28). The period of experimental time was 8 weeks long, met two classes per week. Result: First, the experimental group after teaching in attitude toward physical education, cognition and game performance has significant difference than before. Second, the control group after teaching in attitude toward physical education, cognition and game performance has significant difference than before. Third, After analyzing control and experimental group, results reveal that experimental group was no significantly higher than those of control group in attitude toward physical education. Fourth, After analyzing control and experimental group, results reveal that experimental group was significantly higher than those of control group in cognitive test and game performance. Conclusion: Conducting virtual reality as a technique to teach basketball not only can achieve better performance on students’ cognition, but also can improve game performance.
