Abstract:
The purposes of this research were 1) to study and compare the average of teacher self-efficacy and average of teaching behavior, 2) to develop a cause and effect model of self-efficacy of secondary school teachers under Bangkok educational service area offices, and 3) to examine the goodness of fit of the model with empirical data. The research samples consisted of 502 secondary teachers from the school under Bangkok educational service area offices. Variables consisted of five latent variables: teacher self-efficacy, teaching behavior factor, psychology factor, teacher background factor, and school factor. These latent variables were measured by twenty-five observed variables. The research data were collected by two questionnaires. Data were analyzed by descriptive statistics, oneway ANOVA, Pearson correlation, confirmatory factor analysis, and LISREL analysis. The major findings were as follows: 1. The secondary school teachers under Bangkok educational service area offices‘ teacher self-efficacy are good. The level of teacher’s opinion on psychology factor was different among the students’ grade point average in school level, teacher background factor was different among the school sizes and students’ grade point average in school level at .05 level of statistical significant. Average of teacher self-efficacy was different among the teacher experience, school sizes, and students’ grade point average in school level at .05 level of statistical significant. Average of teaching behavior was different among the students’ grade point average in school level at .05 level of statistical significant. 2. A cause and effect model of secondary school teachers under Bangkok educational service area offices found that teaching behavior was had direct effect on teacher self-efficacy and indirect effect on the psychology factor, teacher background factor, and school factor which passed on teacher self-efficacy. 3. A cause and effect model of self-efficacy of secondary school teachers under Bangkok educational service area offices was fitted with the empirical data ((chi square =53.821, df=58, p=0.631, GFI=0.991, AGFI=0.952, RMR=0.008). The variables in the model accounted for 69% of variance in the teacher self-efficacy and 73% of variance in the teaching behavior.
