The Development of Mathematics Learning Achievement on Ratios, Proportions, and Percentages Based on the Constructivist Approach and the Student Teams-Achievement Divisions (STAD) Cooperative Learning Technique for Matthayom Sueksa One Students at Sriboonyanon School

Abstract

The objectives of this research were: (1) to develop a learning management approach for Ratio, Proportion, and Percentage based on the Constructivist concept combined with the Student Teams - Achievement Divisions (STAD) cooperative learning process, meeting the efficiency criterion of 80/80; (2) to compare students’ mathematics learning achievement before and after receiving the learning management; and (3) to study students’ satisfaction with the learning management. The sample consisted of 34 Matthayom Sueksa 1/1 students at Sriboonyanon School, during the second semester of the 2024 academic year, obtained through cluster random sampling. The research instruments included: (1) lesson plans; (2) a mathematics learning achievement test on Ratio, Proportion, and Percentage; and (3) a student satisfaction questionnaire. This study employed a quasi-experimental research design. Data were analyzed using percentage, mean, standard deviation, and a t-test.

The research findings were as follows:

1. The efficiency of the mathematics learning management was 86.18/80.40, which exceeded the specified criterion.

2. The students’ mathematics learning achievement before and after the intervention were different; the post-test achievement was significantly higher than the pre-test achievement at the .05 level of significance.

3. The overall level of students’ satisfaction toward the learning activities was at the highest level.
