The Effects of Mathematics Activities on the System of Linear Equations with Two Variables on Matthayom Sueksa Three Students Using the Technique of Student Teams Achievement Divisions (STAD)

Abstract

Human beings are evolving all the time. Mathematics is also a tool for the study of science and technology as well as other related sciences. Therefore, the study of the results of group learning activities by using STAD technique was studied in mathematics subject group titled System of Linear Equations in Two Variables. Secondary school year 3 to obtain educational results that will lead to the development of academic achievement and effective learning activities in mathematics. The objectives are 1) to develop mathematical learning activities on a system of linear equations with two variables; of students in Mathayomsuksa 3 who used learning management according to the cooperative learning management method using STAD technique to achieve efficiency according to the criteria 75/75 2) to compare the mathematics learning achievement on the subject of a system of linear equations for two variables. before and after class 3) To study the satisfaction of Mathayomsuksa 3 students from cooperative learning by using STAD technique. The sample group in this research was 40 Mathayomsuksa 3 students at Jomsurang Upatham School. The statistics used were percentage, mean, standard deviation. and t-test.

The results showed that (1) the cooperative learning management method using STAD technique was effective according to the criteria 75/75, found that the efficiency was equal to 79.72/79.17; 2) the cooperative instructional management method using the STAD technique. It was found that after school was higher than before. 3) The students' satisfaction from cooperative teaching and learning by using STAD technique was found to be at a high level.
