The samples in this research were grade 9 students in the Demonstration School of Roi ET Rajabhat University, Selaphum District, Roi Et Province. The 16 samples were selected by using cluster random sampling method. The research instruments were mathematics learning activities using SSCS management plans, Mathematics problem solving ability test, Learning achievement test and the student satisfaction questionnaire of organizing mathematics learning activities using SSCS method. The data analysis used were mean, percentage and standard deviation. The results of the research were as follow. 1) The efficiency of the mathematics learning activities plan was 84.91 / 77.19. 2) The mathematics learning activities management had an effectiveness index of 0.6540. 3) The comparison of mathematical problem-solving abilities were 87.50 percent of all students that passed the criterion score of 75%. 4) Students who learned with mathematics learning activities using SSCS method had satisfaction at a high level with an average of 4.47 and a standard deviation of 0.74.</p>}, number={1}, journal={Journal of Roi Et Rajabhat University}, author={Komal, Autchareya and Prasertsang, Parichart}, year={2021}, month={Apr.}, pages={198-208} }
