The aim of this study is to explore the effects of various feedback frequency of knowledge of results (KR) on the learning of a badminton player in giving long high serves. Ninety freshmen students at Homei Junior High School in Changhua County were selected the subjects of the study. They are split randomly into three groups of equal size with (1) 33% KR, (2)50% KR, and (3)100% KR, respectively. During the study the experiment underwent 150 tryouts, including 10 pretest tryouts, 100 tryouts during practice, 10 instant performing tests, 10 instant transferring tests, and finally 10 retaining and transferring tests each at seven days afterwards. In this investigation, the participant’s performing act is assumed to be the dependent variable while the independent variable is the feedback frequency of KR. The scores measured are first analyzed in one-way ANOVA to compare the difference in learning among the three groups. They are further examined statistically using mixed design of two-way ANOVA and Tukey’s HSD method. The following findings are reported. Firstly, providing various feedback frequency of KR information would affect instant performance, delayed retention, and delayed transfer, but not any eminent influence on the instant transfer. Secondly, during the retention period, the group receiving 100% KR feedback frequency is profoundly superior to the one receiving only 33% KR in the instant performance. In delayed transferring, the group with 100% KR is clearly lower than the group with 33% KR. Finally, during the period of transferring, nearly no difference among the three groups is seen as far as instant transferring is concerned. The group with 100% KR in delayed transfer appears to be lower than both groups with 33% and 50% KR.
