THE LINEAR STRUCTURAL RELATIONSHIP MODEL OF FACTORS INFLUENCING EFFECTIVE TIME MANAGEMENT OF SCHOOL ADMINISTRATORS UNDER THE SECONDARY EDUCATIONAL SERVICE AREA OFFICE IN THE NORTHEAST REGION

Abstract

The purposes of this research were 1) to study the causal factors influencing effective time management of the school directors, and 2) to validate the goodness-of-fit of the hypothesis model of causal factors with the empirical data. The study was divided into 2 phases. The first phase was the building of research conceptual framework by an analysis of relevant documents and researches, and interview with 7 experts and a case study of outstanding 3 standard of royal awarded school. The second phase was the validation of research hypothesis. Data was collected by a 5-level rating scale questionnaire with validity between 0.80 – 1.00, discrimination power between 0.42 - 0.75, and reliability value at 0.98. The samples were school directors under the secondary educational service area office in the northeast year B.E. 2560, totally 505. Sample sizes determination by using 20 times of the observed variables, and samples size was chosen by multi-stage random sampling. Data was analyzed by determining frequency, percentage, mean, standard deviation, Pearson's Product Moment Correlation Coefficient and analyze the causal relationship. Results indicated that 1) the causal factors influencing effective time management of the school directors under the secondary educational service area office in the northeast comprised of 4 factors, time management tools, waste time elimination, time management technique and time planning. 2) The developed model showed a goodness-of-fit with the empirical data (χ² = 36.51, p-value = 1.00, df = 83, χ²/df = 0.43, RMSEA = 0.00, GFI = 0.99, AGFI = 0.98, Largest Standardized Residual = 1.74). The effective time management of the school directors has received direct effect from time planning, and time management tools; indirect effect from waste time elimination, and time management technique; total effect from waste time elimination, time management technique, time planning and time management tools, respectively. When considering the prediction coefficient (R²) of the four cause factors, the accounting for the variations in effective time management of the school directors was 81 percent.
