Validity generalization is a method of establishing the generalizability of the validity of a test by examining the results of all previous validity studies of the test of interest. In this paper, the validity generalization model was introduced and described for criterion-related validity studies. The model is recommended as an approach to clarifying the relationship between a test and a criterion measure in physical education and exercise science.

The objective of this study was to examine the validation of structure of physical self description questionnaire(PSDQ) based on the covariance structure analysis, conducting a wide survey on students involving physical activities as the subject of this study. The students were comprised of ordinary students and athletes of male and female in high schools and universities as well. To put it more specifically, this study was designed to find how the subject of the study react to the 11 multi-level structure of physical self description questionnaire created by Marsh and Redmayne(1994) and, accordingly, which kind of structure model would be resulted from the survey. Based on the structure resulted from the study, in addition, this study was intended to discover whether there is any factor invariance between male and female, high school and university, and ordinary students and athletes. Arid this study was also made to validate the appropriateness to the study. The result of this study was applied to verify the factor structure, utilizing a confirmatory factor analysis with the LISREL 8.12(Joreskog & Sorbom, 1988) program based on maximum likelihood estimation. The result of the study is shown as below. First, when the study was made to ordinary students and athletes of male and female in high schools and universities in Korea, the construct factor of physical self description questionnaire was proved to be composed of nine(9) factors which are confidence in sports, global physical, physical activity, body fat, flexibility, healthy, self-esteem, appearance, and endurance. Accordingly, the result of this study was proved to be different from eleven(11) multi-level of structure for physical self description questionnaire by Marsh and Redmayne (1994). Second, while the validity of factor structure was verified in both eleven(11) construct factor model and nine(9) construct factor model when the study was made to all the students(in high schools and universities, male and female, and ordinary students and athletes), the nine(9) construct factor model was proved to be more adequate one than eleven(11) construct factor model.

The purpose of this study was to investigate the effect of different task presentation timing on students` skill learning of the tennis service. The subjects used for this study were 80 college students who enrolled in beginning tennis and leisure sport class at a university. The task presentation timings were three different conditions. Students performed tennis service 20 times after received information from the videotaped and extend previous modeling research that suggests that the impact of modeling on motor performance and learning is influenced by the timing of the task presentation. The results of the study indicated that this investigation both supported and extend previous modeling research that suggests that the impact of modeling on motor performance and learning is influenced by the timing of the task presentation. The study concluded that providing two times of task presentation during practice was a valid method when students were unsure about the nature of skill and performance.
