The Comparison Between the Effect of Feedback after the Good and Weak Trails to Acquisition and Retention of the Football Dribble Skill

In the present study, the effect of the two methods in offering feedback was examined in good and weak trails to acquisition and retention the football dribble skill. 24 samples were randomly divided into two tentative groups and took part in the first day of the pre-test. Then in 3 days and in every off that they did the group each of 10 trails, and to every of them in each 10 trail group, three feedbacks were given. But in one group on the three good trails and in the other, on the three weak trails, the feedback was given, and they participated in the acquisition test at the end of practice. Finally, after 72 hours, the retention test was carried out. The data were analyzed and by the independent T-test and dependent one, and it became clear that both groups have had progress in the acquisition level and their difference has not been meaningful(p≤0/05). But in the retention test, the feedback group after good trails did better in comparison to the feedback group after the weak trails and their difference was meaningful (p≤0/05). So it can be said that the feedback after the good trails is more effective that the feedback after the weak trails in learning the football dribble skill.
