Results of Using Mathematical Activity Series on Three-Dimensional Geometry and Volume Rectangular Shape by the STAD Cooperative Group Learning Method for Students in Prathomsuksa 5

Abstract

This research were to create a set of mathematical activities on three-dimensional geometric shapes and volumes of rectangular shapes; by using the cooperative group learning method, STAD technique for Prathomsuksa 5 students to be effective according to the criteria of 80/80, comparing the learning achievement between before and after learning with a set of mathematics activities and to study the student's satisfaction with the mathematics activity set by using the STAD-based cooperative group learning method. The samples used in this study were Prathomsuksa 5/2 students at Wat Nong Chok School, Nong Chok District, Bangkok, Semester 2. A total of 40 students, obtained from cluster random sampling by drawing lots. 1 classroom out of 6 classrooms Tools used in the study 1) Mathematics Activity Set 2) Learning 3) Achievement Test.

            The results showed that :1. The developed set of mathematical activities has an efficiency value of E1/E2 = 90.48/80.5. 2. Achievement in Mathematics Their learning achievement after learning was higher than before learning at the statistical significance level of .01. 3. The students' satisfaction with the mathematics activity set. The mean was 4.31, the standard deviation was 0.81, at a high level.
