| Summary: | 碩士 === 國立臺灣體育運動大學 === 體育研究所 === 106 === The purpose of this study was to investigate the effects of learners’ control of video observation on performance, self-efficacy, and error detection capability for the learning of volleyball forearm pass to wall. Forty-two male junior high school students took part in this experiment and were randomly divided into three groups: the self-controlled group, yoked group, and the control group. They were asked to practice volleyball forearm pass to wall for 300 trails, 20 blocks in total, during the three days acquisition sessions. Participants in the self-controlled group could choose the block video they wanted to watch. Participants in the yoked group had to watch the video that paired to the self-controlled group. The control group did not watch any videos. The movement times, self-efficacy, and error detection capability of volleyball forearm pass to wall for one minute were conducted 10 minutes before the acquisition sessions, 10 minutes and 48 hours after the acquisition sessions for the measurement of homogeneity, immediate retention, and delay retention respectively. The dependent variables were used to test the group differences independent one way ANOVA or ANCOVA with Duncan post-hoc test. The results showed that there were no statistical differences among groups at movement times, self-efficacy, and error detection capability during test sessions. However, the rating score of volleyball forearm pass of the delayed retention test showed that the self-controlled group learned better than the yoked group. It indicated that the perception of error detection and self-efficacy had no enhance through the self-controlled video feedback, but the quality of volleyball forearm pass to wall was enhanced.
