Teacher Development Model for High-Performance Schools: Ban Samliam Municipal School, Khon Kaen City Municipality

Abstract

The objectives of this research were: 1) to study the components and indicators of a teacher development model for high-performance schools; 2) to examine the current and desirable states of teacher development; 3) to construct and develop the teacher development model; and 4) to evaluate the implementation results of the model at Ban Samliam Municipal School, under the Bureau of Education, Khon Kaen City Municipality. Methodology: the research sample consisted of 224 teachers under the Khon Kaen City Municipality, selected through simple random sampling. The model was subsequently implemented with a target group of 47 teachers at Ban Samliam Municipal School, selected via purposive sampling. Research instruments included questionnaires on current and desirable states and needs assessment, component/indicator evaluation forms, focus group records, and expert interview forms. Data were analyzed using percentage, mean, standard deviation, Index of Item-Objective Congruence (IOC), discrimination power, reliability, Cronbach’s alpha coefficient, Pearson’s product-moment correlation coefficient, Modified Priority Need Index (PNI modified), and independent t-test. Findings revealed that the overall current and desirable states of the teacher development model towards high-performance schools were at a high level. When considering specific components, "Focus on Learners," "Human Resource Development," and "Effective Leaders" were all rated at a high level, respectively. The developed teacher development model was validated through Educational Connoisseurship. The results of the model implementation revealed that teachers' post-development test scores were significantly higher than their pre-development scores at the .05 level and exceeded the 75% threshold. Furthermore, teachers' development scores were higher than before participating in the project, and overall teacher satisfaction toward the model was at a high level.
