Abstract

The purpose of this research was to investigate the effects of implementing an integrated supervision model to develop teachers’ instructional management competencies: A case study of Wat Phra Koet Khongkharam School. The study employed the G-COSS Integrated Supervision Model, which consists of five steps: 1) Goal Searching (G), identifying goals and development needs; 2) Coordinate Experience (C), coordinating and sharing experiences; 3) Operations Management (O), managing and implementing planned activities; 4) Supervision to Develop (S), providing supervision to develop and enhance teachers’ competencies; and 5) Share to Public (S), sharing knowledge and disseminating the results of implementation. A mixed-methods research approach was employed. The target group consisted of school administrators, teachers, and educational personnel at Wat Phra Koet Khongkharam School. The research instruments comprised a teacher instructional management competency assessment form, a teacher satisfaction questionnaire, and a learner quality assessment form. The research findings revealed that: 1) Following the implementation of the G-COSS Integrated Supervision Model, teachers’ overall instructional management competency was at the highest level ( = 4.66). Teachers were able to design and implement active learning that emphasized learner-centered approaches, appropriately select and utilize instructional media, innovations, and technology, and effectively measure and evaluate learners’ learning outcomes; 2) Teachers’ overall satisfaction with the G-COSS Integrated Supervision Model was at the highest level; 3) Learners’ academic achievement increased after the implementation of the model compared with the previous academic year; and 4) Learners’ key competencies and desirable characteristics showed higher assessment results in all areas. These findings indicate that the G-COSS Integrated Supervision Model is an effective approach for enhancing teachers’ instructional management competencies, supporting their professional development, and improving the quality of learners in a systematic and sustainable manner.
