This research developed academic achievements to attain a pass rate of 70% and assessed student motivation in studying mathematics. The target group consisted of 40 Grade 10 students during the second term of the 2023 academic year at Sarakham Pittayakhom School under the Mahasarakham Secondary Educational Service Area Office. The tools used in this research included (1) a plan for organising 12 cooperative learning activities, (2) a mathematical achievement test on the topic of logarithmic functions, (3) a measure of mathematical learning motivation and (4) a diary record. Statistical data included percentages, means and standard deviations. Content analysis was employed as qualitative data and the action research model was divided into three cycles as Cycle 1 organized cooperative learning activities using the TAI technique with 40 students. Thirteen students (32.50%) passed the 70% criterion, while 27 (67.50%) did not. The average motivation score was 3.46, indicating moderate motivation among all the students. Cycle 2 implemented the STAD technique with the same group. Twenty two students (55%) passed the 70% criterion, while 18 (45%) did not. The average motivation score increased to 4.24, showing high motivation levels. Cycle 3 utilised the Think-Pair-Share. Thirty nine students (97.50%) passed the 70% criterion, with only one (2.50%) failing. The motivation score further increased to 4.46, suggesting very high motivation levels. After completing the operating circuits, almost all the students met the required academic achievement criterion in mathematics and exhibited high levels of study motivation.
