การพัฒนาทักษะ ER-DIAGRAM : การศึกษาความสัมพันธ์เชิงสาเหตุ

บทคัดย่อ

The purpose of this research was to develop and validate causal factors that affect the design skills ER-Diagram. The purposive sampling were 165 students of computer education major 2nd year bachelor of Education Faculty, Bansomdejchaopraya Rajchaphat University (academic 2015-2016). A total of 165 students were purposively collected using questionnaire. Statistical analysis was performed using statistical analysis program. Causal modeling involved in the use of AMOS 16.0. The results were as follows:
1. Variables had direct effects on ER-DIAGRAM design skills were attitudes toward logical thinking and basic skill in computer. While the variables had indirect effects on ER - Diagram design skills were attitudes toward the Educational Database System course, attention to studying and concentration.
2. The model was consistent with the empirical data as demonstrated by the reserve fit measurement chi-square statistics value was not statistically significant with the ration of chi - square value over degree of freedom (χ2 2/df) equal to 1.792. Group indicates were set at equal greater than 0.90. In this study found that GFI equal to 0.972, AGFI equal to 0.903, CFI equal to 0.951 and TLI equal to 0.977. All of the index Pasteli the index criteria. PGFI = 0.621 passed the criteria of 0.50 or above. The indexes with the level less than 0.05 were RMR equal to 0.024 and RMSEA equal to 0.032 which also pass at the index criteria. The predictive power of ER - DIAGRAM was found to be 77.5% due to the correlation coefficient (R2) of 0.775.
