Abstract

The purposes of this research were: 1) to construct and examine the effectiveness of the mathematics instructional packages on Introduction to Logic using a STAD cooperative learning method for Mathayomsuksa 4, 2) to compare students’ learning achievement after learning through the developed packages, 3) to examine the effectiveness index of the developed packages and, 4) to investigate the students’ satisfaction toward learning through the developed packages. The sample, obtained through cluster random sampling, consisted of 41 Mathayomsuksa 4/1 students studying in the first semester of academic year 2018 at Buakhao School, Kuchinarai district, Kalasin province. The research tools included: 1) six volumes of mathematics instructional packages, 2) six lesson plans, 3) a 30-item learning achievement test with 4-multiple choice questions, and 4) a student satisfaction test with a five-point rating scale. The statistics for data analysis were percentage, mean, standard deviation and t-test for Dependent Samples. The results were as follow: 1. The developed mathematics instructional packages on Introduction to Logic using a STAD cooperative learning method for Mathayomsuksa 4 achieved the efficiency of (E1/E2) 81.34/81.95 which was higher than the defined criteria of 75/75. 2. The students’ learning achievement after the intervention was higher than that of before at the .05 level of significance. 3. The effectiveness index of the developed mathematics instructional packages was 0.7124 which was 71.24 percent. This suggests that the overall students’ learning progress increased by 71.24 percent. 4. The students’ satisfaction toward learning through the developed mathematics instructional packages was at the highest level.
