THE DEVELOPMENT OF THE STRUCTURAL EQUATION MODEL OF FACTOR AFECTING EFFECTIVENESS OF THE MEDIUM SIZED SECONDARY SCHOOLS UNDER SECONDARY EDUCATIONAL SERVICE AREA OFFICE 22

Abstract

           The purposes of this study were to 1) develop a structural equation model of factors affecting the medium-sized secondary schools effectiveness under secondary educational service area office 22, and 2) examine the goodness-of-fit of structural equation model of factors affecting the medium-sized secondary schools effectiveness under secondary educational service area office 22 with the empirical data. The study was divided into 2 phases: the first phase was determinate conceptual framework by studying document and research, the second phase examined the goodness-of-fit of the model with the empirical data which was collected from 48 school administrators and 452 teachers. The research instrument was rating scale questionnaires with the goodness-of-fit of .60-1.00, the reliability of .97, and the discrimination power of .38-.88. Data was analyzed by descriptive statistics by using SPSS and LISREL 8.52.
          The findings of the study were:
          1. The structural equation model of factors affecting effectiveness of the medium sized secondary schools under secondary educational service area office 22 consisted of 4 variables including 1) instructional leadership has 3 observed variables, 2) organization's culture has 5 observed variables, 3) school climate has 3 observed variables, 4) learning process management has 5 observed variables, and school effectiveness has 4 observed variables.
          2. The structural equation model of factors affecting effectiveness of the medium sized secondary schools under secondary educational service area office 22 was consistent with the empirical data with Chi-square value () = 76.31, degree of freedom (df) = 98, P-value = .949, Goodness of fit index (GFI) = 0.98, adjusted goodness of fit index (AGFI) = 0.97, and root mean square error of approximation (RMSEA) = .00.
