A Study of Mathematical Achievement on Polynomials Using Collaborative Learning with TAI Technique of Mathayomsuksa 2 Students

Abstract

The objectives of this study were: 1) to study the effectiveness of a learning activity package based on cooperative learning with the Team-Assisted Individualization (TAI) technique on the topic of polynomials for Mathayomsuksa 2 students, aiming to meet the 80/80 efficiency criterion; 2) to examine the extent to which students’ mathematics achievement improved following the TAI-based instructional intervention; and 3) to assess students’ satisfaction with the TAI-oriented cooperative learning environment. The sample consisted of 32 Mathayomsuksa 2 students from Sinpunkhunnawit School during the first semester of the 2025 academic year. The participants were selected through proportional stratified random sampling and classified into        high-, moderate-, and low-achieving groups. The research instruments comprised six TAI-integrated lesson plans, a 30-item multiple-choice mathematics achievement test, and a five-point Likert-type satisfaction questionnaire. Data were analyzed using descriptive statistics and paired-samples t-tests.
The findings revealed that:
 
1) the learning activity package incorporating cooperative learning with the TAI technique on the topic of polynomials for Mathayomsuksa 2 students demonstrated an efficiency of 84.43/81.15;
 
2) students’ mathematics achievement on the topic of polynomials after participating in cooperative learning with the TAI technique was significantly higher than before the instruction, at the .05 level of statistical significance; and
 
3) students’ satisfaction with cooperative learning using the TAI technique on the topic of polynomials for Grade 8 students was at a high level.
