This participatory action research project responded to the needs for educational reform and involved cooperation between Mahasarakham Municipality, which provided primary school education, and the Faculty of Education at Mahasarakham University, which played a role as academic mentor. The project aimed to improve the quality of education management by empowering teachers. In order to do so the school had to admit restricted opportunity students rather than well qualified ones. The project, which was divided into four phases, took place between 2000 and 2005. It studied collaboration between the teaching staff of the Faculty of Education who worked as academic mentors and a group of 160 teachers at seven municipal schools. In Phase 1 the emphasis was on the development of 40 model teachers from these seven schools, giving them the skills to design curricula, promote learner-centred instruction, and undertake classroom action research for problem solving. In Phase 2 this developmental activity was extended to all 160 teachers. In Phase 3 the emphasis was on the extension of teacher networks to exchange learning among these schools and to develop best practices. In Phase 4 the emphasis was on developing the curricular management system in each school to ensure and enhance quality and in order that teachers could meet national teaching standards. This would promote a positive attitude and enhance the confidence of the parents and the community in the schools because the teachers would be as qualified as those from successful government schools. The interventions used in the four phases were: workshop training, coaching, learning exchanges, clinical supervisory visits, and reflection. The results of the research and development had a positive impact on raising the quality of teaching and the curriculum in the schools and promoted educational opportunities for disadvantaged students.
