The Effect of Selective and Compulsive Video Augmented Information on Motor Learning of Basketball Jump Shot: with Emphasizing on the Challenge Point Theory

The aim of this paper is to investigate the effect of selective and compulsive video augmented information on motor learning of Basketball Jump Shot emphasizing on the Challenge Point theory. 80 male students (18to22 years old) were voluntary selected. After homogenization based on the first pre-test scores (block5of trial) they were randomly assigned into four groups (20subjects) of self-control, yoked, examiner-control, and control. Instructional video of the expert model demonstrating specific biomechanical component was provided for 6 minutes. And then a second Pre-test (block5of trial) was done. The acquisition phase included 10 blocks of 5 trails and the retention test was performed in 2 blocks of 10 trails after 24 hours. The acquisition accuracy and technique scores differences were analyzed using a repeated measures analysis of variance (RM-ANOVA) in 4(groups) x 10(Block). The retention accuracy and technique score differences were analyzed using the analysis of variance (ANOVA). The results of accuracy in the acquisition phase showed that the main effect of the block is significant. In the retention phase, the accuracy scores in the experimental conditions were significantly higher than the control group. The results of accuracy in the acquisition phase demonstrated that the main effect of the block, group, and interaction of the block and the group is significant, and the skill performance of self-control group was significantly better than the yoked and control groups. In the retention phase, the self-control group technique of skill performance was better than other experimental conditions, and examiner-control group was significantly better than the control conditions during the acquisition and retention phases.
