THE EFFECT OF COOPERATIVE LEARNING BY TAI TECHNIQUE ON ANALYTIC GEOMETRY IN MATHEMATICS LEARNING ACHIEVEMENT FOR MATHAYOMSUKSA 4 STUDENTS

Abstract

The purpose of this study were 1) to compare pre-test and post-test of academic achievement who studied Mathematics with the TAI technique on the subject of analytic geometry 2) to compare academic outcomes of Mathayomsuksa 4 students who studied Mathematics after learning with the TAI technique on the subject of analytic geometry to the 70% standard and 3) to observe the behavior of working together as a group of Mathayomsuksa 4 students. The research population were 450 Mathayomsuksa 4 students in the first semester of 2020 academic year at Suankularb Wittayalai School, Bangkok. The sample consisted of 45 Mathayomsuksa 4 students they were randomly selected by simple sampling. The research instrument employed in this study was a set Mathematics lesson plans on the subject of analytic geometry for Mathayomsuksa 4. The lesson plans comprised seven plans. The test for academic results consisted of 25 fourchoice questions with discrimination values for individual questions ranging from 0.27 - 0.83 and Difficulty index values ranging from 0.47 - 0.83 and reliability of 0.79. The data were analyzed employing paired t-test. The results of the study are described as follows 1) the students post-test achievement higher than pre-test achievement with the .05 statistically significant 2) the post-lesson academic outcomes on the subject of analytic geometry of Mathayomsuksa 4 students who learned with the TAI technique was higher than 70% of standard at the .05 statistically significant 3) the group working behavior of students in cooperative learning with the TAI technique group was very high leveled at 83.42 percent of the full score.
