การพัฒนาแบบฝึกทักษะคณิตศาสตร์ เรื่อง ความน่าจะเป็น โดยใช้การเรียนรู้ แบบร่วมมือร่วมกับเทคนิค KWDL สำหรับนักเรียนชั้นมัธยมศึกษาปีที่ 3

Abstract

The purposes of this research were to: 1) examine the efficiency of the mathematical skill exercises on probability using cooperative learning TAI technique and KWDL technique for Mathayomsuksa 3 students to meet the efficiency criteria set of 75/75,2) investigate the effectiveness index of the developed mathematical skill exercises, 3) compare the student learning achievement before and after the intervention, and  4) explore the student satisfaction toward learning through the developed mathematical skill exercises. The sample consisted of 40 Mathayomsuksa 3 students studying in the second semester of the academic year 2019 of Buakhao school, Kuchinarai district, Kalasin province, obtained through a cluster random sampling. The research instruments were : 1) Six sets of the mathematical skill exercises, 2) 16 lesson plans, 3) a 30-item achievement test with a discriminative power (B) ranging from 0.23 to 0.73 and a reliability (r_cc) of 0.91, and 4) a 20-item satisfaction test with a 5- point scale, a discriminative power (r_xy) ranging from 0.36 to 0.70 and a reliability ( ) of 0.89. The statistics for data analysis were percentage, mean, standard deviation and t-test (Dependent Samples).

            The findings were as follow: 1) The developed mathematical skill exercises had an efficiency of 80.05/78.67 which was higher than the criteria set of 75/75, 2) The effectiveness index of the mathematical skill exercises was 0.6109 or 61.09 percent, 3) The students’ learning achievement after the intervention was higher than that of before the intervention at the .01 level of significance, and 4) The student satisfaction toward the mathematical skill exercises as a whole was at the highest level.
