| Summary: | 碩士 === 國立屏東教育大學 === 體育學系 === 98 === The purpose of this study is to investigate the situation of exercise by different groups and the differences of the pre-test, post-test, and retention test performance of throwing skills by different gender of fifth and sixth grade students. This study is experimental research and it takes eighty senior-grade students (forty boys and forty girls ) of Zhao Ming elementary school in Kaohsiung County who have not trained of throwing as research objects for a period of two weeks, twice a week, the eighteen T-ball throwing teaching and practice each time. After two weeks practice, it takes the skill exam immediately and it implements the retention test after a week to analyze the throwing skill performance and gender differences; it bases on different groups (serial practice group, random practice group, blocked practice group and control group), different gender (male, female) with different test time (pretest, posttest, retention test) as independent variables, throwing performance scores as dependent variables, and it was examined by mixed design of three-way ANOVA. If the interaction is differentsignificantly, it takes simple interactions test and it carried out the test of simple simple main effect for which is significant difference. In this study, significant level set at α =. 05. The results were showed:
1. There is significant difference in performance of the
contextual interference practice of different groups on
the fifth and sixth grade students for their T-ball
throwing skills. Blocked practice group is better than
the random practice group and control group and there
is no significant difference with the serial practice
group.
2. The gender difference of the fifth and sixth grade
students for the T-bal throwing skills is significantly
different in performance that boys outperformed girls
in throwing skills.
3. Throwing skills of different test time are distinctly
different performance. The post-test is better than pre-
test and there is no significant difference between
the retention test with pre-test and post- test.
4. There is no interactive relation among different
group, different gender and test time.
