The Effect of Cooperative Learning Using TGT Technique on the Addition, Subtraction, Multiplication, and Division of Integers on Enhancing Learning Achievement for Grade 7 Students

Abstract

                  This research aims to 1) compare the learning achievement in addition, subtraction, multiplication, and division of integers before and after using cooperative learning using TGT technique, and 2) study the students’ satisfaction with the cooperative learning using TGT technique in learning addition, subtraction, multiplication, and division of integers. The sample group consisted of 28 Grade 7 students enrolled in the first semester of the 2024 academic year at Songplueywittayayon School, Namon District, Kalasin Province. The sample was selected using
a purposive sampling method. The research instruments included four lesson plans the quality was at the highest appropriate level, with an average score of 4.87, a 20-item learning achievement test the test had IOC values ranging from 0.67 to 1.00, difficulty indices from 0.30 to 0.65, discrimination indices from 0.20 to 0.40, and a reliability coefficient of 0.74, and a 10-item satisfaction questionnaire the IOC value was 1.00. The statistical methods used in the research were percentage, mean, standard deviation, and t-test for dependent samples. The findings revealed that:
1) The students’ learning achievement after the cooperative learning implementation was significantly higher than before at the .05 level. 2) The students’ overall satisfaction with the cooperative learning approach was at the highest level  (x =4.51, S.D.= 0.59).
