The Development of Mathematics Achievement in Triangles for Grade 6 Students by Using STAD Techniques (Student Teams Achievement Division: STAD) for Skill Development

The Development of Mathematics Learning Achievement on Triangles for Grade 6 Students Using Skill-Enhancement Exercises Based on the STAD Technique

Abstract

This research aimed to: 1) develop mathematics learning activity plans on the topic of triangles for Grade 6 students using the STAD (Student Teams Achievement Division) cooperative learning technique combined with supplementary exercises to meet the 80/80 efficiency criterion; 2) compare students’ learning achievement before and after the implementation of the learning activities; and 3) examine students’ satisfaction toward the learning activities. The sample group consisted of 44 Grade 6 students selected through purposive sampling. The research instruments included lesson plans, a learning achievement test, and a student satisfaction questionnaire. Data were analyzed using mean, standard deviation, and dependent t-tests. The results revealed that: 1) the developed learning activity plans met the 80/80 efficiency criterion; 2) students’ post-learning achievement was significantly higher than their pre-learning achievement at the .05 level; and 3) students expressed a high level of satisfaction with the learning activities that integrated the STAD technique and supplementary exercises. These findings suggest that using the STAD technique in conjunction with supplementary exercises effectively enhances students’ academic performance and fosters positive learning attitudes.
