Abstract
The purpose of this study was to set up standard on defensive game performance in baseball type game for junior high school students. To achieve the purpose, following task was set: Based on student's performance success rate, expected performance level in tentative standard was assessed.
The participants (n=32) were first grade students in a junior high school. Students game performance in a 15 hours unit were taken by video camera, and their game performance were analyzed based on following categories; catching, throwing, and decision-making on throwing, and assessed from the following perspectives;the number of success, the number of failure, and the success rate. In addition, based on French et al. (1991),expected achievable success rates criteria were examined.
The results were as follows:
1) In catching, 50% students have shown more than 70% success rate, little less than 80% of them, more than 60%. All students have achieved more than 50% of it.
2) In throwing, little less than 80% students have shown 70% success rate, more than 90% of them, more than 90%. All students have shown more than 50% of it.
3) In decision, 70% students have shown more than 80% success rate, more than 80% of them, 70%. More than 90% of them have shown more than 60% of it.
To make more reliable performance criteria, number of participants should be added.
