We could say that the knowledge of results is very important factors in the motor skill learning. This paper was analyzed to stipulate how inside-kick of soccer affect to perform when we present the accuracy of the knowledge of results and post-knowledge of results interval. I randomly selected 60 students in the Hakjin elementary school in Busan, and divided 6 groups. The results were as follows. 1. The qualitative and quantitative knowledge of results in the early motor learning stages were not significant difference in each other of the exercise and the transfer performance. 2. When we tried various time interval of the post-knowledge of results interval in the early motor learning stages, there was very significant difference at P=0.05 level in transfer performance . 3. There was no significant between the accuracy of the knowledge of results and post-knowleclge of results in interaction effects. 4. The most effectively performed group in this experiment was as the quantitative knowledge of results who performed 6 seconds of post-knowledge of results interval.
