        The purpose of this study was to examine the effect of blocked, serials and random practice in learning basketball jump-shoot. The subjects, thirty male students in P Middle School who were willingly applied for the experiments, were divided into three groups (each group has ten subjects) : the group for blocked practice, serials practice and random practice. In other to ascertain any differences among the groups another analysis was performed by Turkey's HSD. ANOVA was conducted to test the data. The conclusions are as followings: First, Blocked practice was more effective than serials practice, serials practice was more effective than random practice to improve basketball jump-shoot learning in acquisition phase. Second, Random practice was more effective than serials practice, serials practice was more effective than blocked practice to improve basketball jump-shoot learning in retention phase. Third, Random practice was more effective than serials practice, serials practice was more effective than blocked practice to improve basketball jump-shoot learning in transfer phase.

        The purpose of this study is to investigate of relative efficiency between every-trial knowledge of result and bandwidth knowledge of result on the learning of volleyball under-hand serve. This study used junior high school students of third grad who never had experience about volley ball. This study objects were divided three groups which had ten girls. The each groups were endowed by every-trial knowledge of result, by 2m bandwidth knowledge of result, and by 4m bandwidth knowledge of result. The result of this study are follows. First, in acquirement stage, to endow by every-trial knowledge of result isn't different from to endow by bandwidth knowledge of result. Second, in learning stage, it is more improved learning to endow by 4m bandwidth knowledge of result than to endow by every-trial knowledge of result, but it isn't different from to endow by 2m bandwidth knowledge of result.

      • 내적, 외적 상상 연습이 볼링 학습에 미치는 영향 : Focused on the Ⅱ grade boy students in junior high school

        이경엽,김달영 公州大學校스포츠科學硏究所 1999 스포츠科學硏究所論文集 Vol.- No.13

        The purpose of this study is to find the influence of internal and external imagery practice on bowling performance. The subjects were 28 second-year students in Sogwi Boys School. They took part in the school bowling Club which met once a month. At first the subjects were divided into four groups in order to distinguish among the groups. The first group was the control group. The second group did internal imagery and physical practice at the same time. Third group did external imagery and physical practice simultaneously. The last group did physical practice only. Each group of students, except the control group, was trained tow times a week for 4 weeks. After that, post-performance evaluation was conducted. To find the correlation among the groups, a one-way ANOVA and the Newman-keuls method of statistical analysis was used. From this study, it can be concluded that internal and external imagery practice improves bowling scores than control group, when they are used in conjunction with physical practice. There was, however, no statistical difference in bowling scores between the internal and external imagery groups.

        The purpose of this study was to investigate the effect of team Cohesion and collective efficacy on performance score in tennis teams. The subjects of this studed is taken from the66 tennis players from the university team who participate in the 78 national sports festival. Among them are 34 males and 32 female (31 upper class players and 35 low class players) among who won any prize are defined as the upper class, vice versa. To asses team cohesion, the four-scale Group Environment Questionnaire (GEQ) developed by Widmeyer et. al(1985) was used. In addition to the GEQ items. The questionnaire also contained two questions that assessed collective efficacy expectation : “What playing do you expect to attain in the present sport festival?” “How confident are you that your team will attain this playing” The results were as follows Fistly, Regardless of sex(male & female), there was no a significant difference between team cohesion and team performance in the upper class and the low one. Secondly, but regardless of sex, there was a significant difference between an upper class and a low class in the individual attraction to group-task and group integration-task cohesion. There was a significant difference between male and female in the group union-social cohesion. In addition, there was a significant difference in the individual attraction to group-social cohesion's interaction. Thirdly, regardless of sex, there was a significant difference between an upper class and a low one in the collective efficacy team performance score.

      • 女子 高等學生의 運動 遂行 結果에 對한 歸因 性向 分析

        This study is to help our physical education teachers to teach their students by letting them recognize the cause of success of failure in performing exercise, consequently reinforcing the learning motive for the following learning, and by enabling to develop the more effective study programs through making an analysis of attributional disposition for success or failure. Using the measure for test of attributional type by Russel and Maccley(CDS), this study was done on the two groups of students who were at the second grade of B-girls' high school in Puyo Chungnam-do, each of which was consisted of 100 students. One group was satisfied with the accuracy of badminton service and the other was not. First, How can the students' attribution from results make a difference according to whether they are satisfied with or not results from the test for accuracy of badminton service? Second, How can the students' score under each attribution make a difference according to whether they are satisfied with or not results from the test for accuracy of badminton service? Third, How can the students' score under each attribution from results make a difference according to the result attribution of the test for accuracy of badminton service? Based on the collected data, I did -test, T-test, F-test and Scheff e by spss pc. According to the above data, the conclusions can be inferred like these : First, satisfaction-group with the accuracy of badminton service attributes its success to effort; and dissatisfaction-group to luck. Second, the group under internal-control-dimension feels very satisfied with the accuracy of badminton-service, and the group under extra-control-dimension and instability dimension doesn't do so. Third, the group under stability-dimension, attributing its success to ability and task, makes more scores than the other, attributing to effort and ability. The group nuder internal-control-dimension, attributing its success to effort and ability, makes more scores than the other, attributing to luck and task. The group nuder extra-control-dimension, attributing its success to luck and task, makes more scores than the other, attributing to effort and ability. From the above results, the conclusion can be inferred like this: It is desirable that the attribution about the result from motor-performance should be under internal-control-dimension rather than extra-control-dimension and under instability-dimension rather than stability-dimension.

        Theoretical Prediction of Tunability Enhancement in Coplanar-type Capacitors by Adopting Embedded Electrodes Structure

        김달영,윤석진 한국물리학회 2005 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.46 No.1

        Embedded electrodes structure is introduced in microwave tunable capacitors. In theoretical estimation with reasonable device parameters, embedded-electrodes-structured tunable capacitors show higher tunability than coplanar-type ones. The embedded electrodes structure is also predicted to improve communication quality factor of the tunable capacitors.
