The target group consisted of 30 seventh grade students which the purposive sampling method was applied to select. The research instruments were lesson plans and learning activities based on to the TPACK concept in graph and linear relationships, the level of mathematical conceptual understanding’s test, and the satisfaction questionnaire. The data were analyzed by using percentages, mean, and standard deviations.          </p> <p>The research findings were as follows: 1) The effectiveness of the developed learning activities based on the TPACK concept of graph and linear relationships was 86.56/87.28 which was higher than the 75/75 criteria. 2) After studying with learning activities developed based on the TPACK concept of graphs and linear relationships. Students’ math comprehension scores are at the highest action (A) level, followed by process (P) and learning (O), respectively, and 3) The student’s level of satisfaction toward the learning activities based on the TPACK concept in graphs and linear relationships were at the high level (µ = 4.47, σ = 0.78).</p>}, number={2}, journal={Journal of Graduate Research}, author={Saengrung, Phiraphat and Comesorn, Sukkaew and Pumsanthia, Uthen}, year={2022}, month={Dec.}, pages={71–86} }
