The Study of Mathematical Problem-Solving Ability Using TAI Technique Cooperative Learning Activities on Factoring Quadratic Polynomials of Matthayomsuksa 2 Students at Muang Suratthani School

Abstract

                  The objectives of this research were to 1) study the mathematical problem-solving ability using TAI technique cooperative learning activities on factoring quadratic polynomials of Matthayomsuksa 2 students, 2) compare the students’ mathematical problem-solving ability after participating in the cooperative learning activities with the 70% criterion, and 3) examine the students’ satisfaction level with the use of cooperative learning activities. The cluster random sampling was utilized, resulting in a study sample of 42 Matthayomsuksa 2 students from one classroom at Muang Suratthani School during semester 2 of the academic year 2023. The research data collection instruments employed consisted of nine lesson plans on mathematical problem-solving ability using TAI technique cooperative learning activities on factoring quadratic polynomials of Matthayomsuksa 2 students development, a teacher behavior observation form, a student behavior observation form, a post-learning record, logbooks, student interviews, a 9-item subjective post 1-4 operation cycle test, a 5-item subjective mathematical problem-solving test, and a 15-item questionnaire with a 5-point rating scale on student’s satisfaction with the use of TAI technique cooperative learning activities. The statistical measures employed for data analysis included the mean, standard deviation, and One Sample T-test.
