Abstract:
The purposes of this study were to 1) analyze the factors affecting the scientific projects qualities of the colleges under the Office of Vocational Education Commission, and 2) develop the causal relationship models of the factors affecting those projects. The samples were as follows: 1) 829 third year vocational certificate students, 2) 26 science instructors, and 3) 829 parents. The research instrument was a set of questionnaires developed by the researchers and adapted from relevant studies. The validity indexes of the questionnaire were 0.725 0.851. The findings were as follows: 1. By analyzing the factors, it was found that the parents roles, atmospheres promoting learning, scientific processes, science achievements, psychological science, achievement motivations, science project advisors roles, and scientific projects qualities were consistent with the empirical data. 2. By examining the causal relationship model, it was found that the model was consistent with the empirical data. The chi-square index was 1482.37. The p-value was .000 at the degree of freedom of 744. The index of df/2 was 1.992, the CFI was .98, the GFI was .92, and the AGFI was .91. The root mean square error of approximation (RMSEA) was 0.035. The co-efficient of the dependent variable (i.e. the qualities of the scientific projects) was 0.520. This revealed variables of the model could explain the variance percentage of the qualities of the scientific projects correctly at 52 percent.
