The statistics used for data analysis were mean, standard deviation, and hypothesis testing by t-test (Dependent sample). The result of the research found that 1) the learning  activity by using group learning activities with TAI Technique of Mathayomsuksa 2 students was 80.53/74.40 meeting the specified criteria, 2) The learning achievement using group learning activity with TAI Technique had higher score than before learning at the statistically significant level of .01 and <strong>3) </strong><strong>the students’ satisfaction towards the learning activities using group learning activities with TAI</strong><strong> technique</strong><strong> overall was at the highest level</strong> ( = 4.52 , S.D. = 0.52 ) .</p>}, number={1}, journal={Journal of Education Rajabhat Maha Sarakham University}, author={Donpudsa, Piyanut and Khechornphak, Thanyaluck}, year={2022}, month={May}, pages={131–140} }
