Development of Mathematics Activity Through Cooperative Learning with the Geometer’s Sketchpad Program to Encourage Learning Achievement and Creative Thinking Skills of Mathayomsuksa 2 Students

Abstract

The purposes of this research were to: 1) develop mathematics learning activity packages on geometric transformation by using the cooperative learning model and the Geometer’s Sketchpad (GSP) for Mathayomsuksa 2 students; 2) study the students’ achievement on geometric transformation by using the cooperative learning model and the GSP; and 3) examine students’ creative thinking skill on geometric transformation by using the cooperative learning model and the GSP. The sample was Mathayomsuksa 2 students in the first semester in the 2017 academic year at Chiangdaowitayakom School,1 classroom selected by the cluster sampling method. The learning achievement test employed the one-group pre-test/post-test design. The data were analyzed for percentage, mode, mean, standard deviation, coefficient of variation (CV), effectiveness of learning packages (E1/E2), t-Test: Paired Two Sample for Means and z-test. The results of research were as follows:

1. The development of the mathematics learning management activities yielded five packages. They included foundation of geometric transformation, translation, reflection, rotation, and application. The efficiency of the packages was at 81.61/80.34, higher than the predetermined criterion of 75/75.


2. The learning achievement after learning was higher at the significance level of 0.01. The students’ mathematical skills and processes including problem solving, reasoning, communication, and integeration
   of knowledge were at a good level.


3. The assessment results of the creative thinking skills for mathematics revealed that at least 50 %
   of the students had creative thinking skills at a good level with the significance level of 0.01.
