Taking the six grade students of Chiao Rong Elementary School, Taichung County, who have not the experience of basketball training, as the subjects（N=50）.It assigned them to high CI with visual feedback group, high CI with spoken feedback group, low CI with visual feedback group and low CI with spoken feedback group, to carry out 16 times during 8 weeks of basketball set shot practice. All subjects’ grade of set shot accuracy was recorded every practice, and recorded the movement preference by DV. After eight weeks practice , taken acquisition tests, transfer tests and retention tests of eight weeks. The independent variables were CI（HCI、LCI）and feedback styles（visual、spoken）, and the dependent variables were grade of evaluate and score the student’s set shot accuracy and movement preference. Descriptive statistics two way ANOVA and two way trend analysis. This study set the significant level（α） for all assumed tests at .05. The conclusions made from this research range were as follows: 1.The score of basketball set shot skill accuracy : On the acquisition , transfer and retention stage the interaction effect between different contextual interference and visual feedback had not reached significant level. On the acquisition and retention stage, the low CI group was significantly better than high CI group; In the transfer stage, each group had not reached significant level. The performance of basketball set shot skill :In the acquisition and retention stage ,each groups had not reached significant level.2. In the score of basketball set shot skill accuracy, high CI with visual feedback group、high CI group and visual feedback group, the score appeared linear trend week by week.3. In the performance of basketball set shot skill, high CI with visual feedback group、low CI with visual feedback group and visual feedback group appeared linear trend. High CI with visual feedback group and visual feedback group ,the score appeared quadratic trend at the same time.4. This study hope will be helpful for physical education and school administrative in aftertime.
