THE DEVELOPMENT OF LEARNING ACHIEVEMENT IN SOCIAL STUDIES RELIGION AND CULTURETHROUGH THE COOPERATIVE LEARNING APPROACH (STAD) OF MATTHAYOMSUKSA 1/1 STUDENTS AT SANAMBIN SCHOOL

Abstract

This classroom research aimed to : 1) develop students’ learning achievement in Social Studies, Religion, and Culture through the STAD cooperative learning method, 2) compare students’ learning achievement before and after instruction, and 3) examine students’ satisfaction with the STAD learning approach. The target group consisted of 38 students from Grade 1/1 at Sanambin School in the first semester of the 2025 academic year, selected through purposive sampling. The research design was a one-group pretest–posttest experimental design. The research instruments included eight STAD-based lesson plans, a 30-item multiple-choice achievement test, and a 20-item student satisfaction questionnaire. The data were analyzed using percentage, mean, standard deviation, and t-test. The results revealed that the students’ posttest scores were significantly higher than their pretest scores at the .05 level. In addition, the students’ overall satisfaction with the STAD cooperative learning method was at the highest level. These findings indicate that the STAD approach effectively enhanced students’ learning achievement and promoted positive attitudes toward learning.
