Abstract: (8 Views)
This research aimed to provide an efficient model for measuring and improving educational quality in schools, using statistical process control (SPC) tools and within the framework of total quality management (TQM). The study was conducted as a case study in one of the rural girls' high schools in Babolsar city. In the first stage, initial tests were taken from five main subjects and the data were analyzed using process control charts and Minitab software to determine the level of stability of educational performance. To identify the factors affecting academic failure, a Pareto chart was drawn and the process capability index was calculated at the same time. Its initial value was equal to 0.47, which indicates the relative inefficiency of the educational process in responding to the learning needs of students. Based on these results, three stages of targeted educational intervention were designed and implemented. The findings showed that statistical control tools were able to accurately identify the critical points of academic failure and the implementation of phased interventions led to a gradual improvement in student performance. Post-test data analysis showed that the average scores in all five subjects increased and the range of score changes decreased. Also, the process capability index after the interventions increased from 0.47 to 1.1, which indicates a significant improvement in the stability and quality of educational performance. The reduction in out-of-control points in the process diagrams also indicated an increase in the stability of the educational system after the model was implemented. The final results show that combining statistical process control tools with total quality management principles can provide an effective model for monitoring and improving educational quality and pave the way for more accurate planning and continuous improvement in schools.
