The effect of feedback types on the performance and trnsfer of volleyball underhand serve

The purpose of this study is to demonstrate what kind of feedback is more effective in learning underhand volleyball serve by comparing and analysing the effect feedback on the process of learner's performance and transfer. The subjects of this study were 40 female school students were selected at random, each 10 being divided into four groups. The dependent variabl of this study was specified to measure absolute error, variable error, radial error and directional angle considering the direction and error distance form goal area The results of this study are as follows1. self-regulation feedback and bandwidth feedback have no effect on absolute error seen in process of learning underhand volleyball serve.. 2. self-regulation feedback and bandwidth feedback are more effective in reducing the variable error seen in process of learning underhand volleyball serve. 3. bandwidth feedback is more effective in diminishing radius error seen in process of learning underhand volleyball serve. 4. self-regulation feedback and bandwidth feedback have no effect on the directional error seen in process of learning underhand volleyball serve. As a result, judging from the above findings of this study, self-regulation feedback and bandwidth feedback show greater effectiveness in learning motor skill related to educational task.Ⅰ. 서 론 1 1. 연구의 필요성 1 2. 연구의 목적 4 3. 연구의 문제 4 4. 용어의 정의 5 Ⅱ. 이론적 배경 6 1. 피드백의 개념 6 2. 피드백의 형태 7 3. 피드백 제시방법 12 Ⅲ. 연 구 방 법 20 1. 피험자 20 2. 실험과제 21 3. 실험절차 22 4. 통계처리 23 Ⅳ. 연 구 결 과 24 1. 절대오차 24 2. 가변오차 27 3. 반경오차 30 4. 방 향 각 33 Ⅴ. 논의 35 Ⅵ. 결론 40 참고문헌 41 Abstract 4
