The Effects of Mathematics Learning Activities on Geometric Construction Based on the Constructivism Theory on Matthayom Sueksa One Students

Abstract

The quasi-experimental research aimed to develop a set of learning activities to be effective according to the criteria of 80/80 and compare the achievement between prior to and after the study and to study the students’ satisfaction toward the geometric construction based on the constructivism theory learning activities. The sample population consisted of thirty-five Matthayom-Sueksa-1 students in the first semester of the academic year 2019 in one classroom at the Demonstration School of Ramkhamhaeng University (Secondary Level) using the technique of cluster sampling. Additionally, the research instruments were (1) the academic achievement test, which the difficulty level, discrimination level, confidence interval level, was .25-.78, .20-.71, and .862 respectively. (2) the satisfaction of students towards organizing learning activities evaluation form, which the reliability of Cronbach alpha was .817. (3) the organizing learning activities, which the consistency index value (IOC) was 1.00. The experts all agreed to allow the researcher to conduct this research for the students’ effectiveness and efficiency.
Findings are as follows: 1) The mathematics learning activities developed exhibited an efficiency of 84.95/83.62. 2)The academic achievement in mathematics of the students was higher after the learning activities at the statistically significant level of .05 as they had more opportunities to learn in a real situation as a team. Therefore, they were proud of themselves because they were able to construct their own consensus about what they had learned according to the learning activities which were the aim of this research. 3) The student satisfaction with the mathematics learning activities overall was at the highest level with a mean of 4.64.
