THE LEARNING MANAGEMENT USING ACTIVITY BASED LEARNING WITH COOPERATIVE LEARNING ON MATHEMATICAL PROBLEM SOLVING ABILITY AND LEARNING ACHIEVEMENT IN LINEAR EQUATIONS IN ONE VARIABLE OF SEVENTH GRADE STUDENTS FROM SRINAKHARINWIROT UNIVERSITY PRASARNMIT DEM

Abstract

The purpose of this study were 1) to compare mathematical problem-solving ability and learning achievement of seventh grade students at Srinakharinwirot University Prasarnmit Demonstration School (Secondary) before and after using activity–based learning with cooperative learning 2) to compare mathematical problem-solving ability and learning achievement of seventh grade students at Srinakharinwirot University Prasarnmit Demonstration School (Secondary) after using activity–based learning with cooperative learning to the criterion of 70%. The experimental method is Quasi-Experimental Research by One Group Pretest–Posttest Design. The participants in this study were 32 seventh grade students studying in the second semester of the academic year 2020. They were selected by using the cluster random sampling technique. The instruments used in this study were lesson plans, mathematical problem-solving ability test and learning achievement test. The statistics procedures used for data analysis were mean, standard deviation, t-test for dependent samples and t-test for one samples. The results showed that 1) the mathematical problem-solving ability and learning achievement of seventh grade students after using activity-based learning with cooperative learning was higher than before at a statistically significant level of .01, 2) the mathematical problem-solving ability and learning achievement of seventh grade students after using activity-based learning with cooperative learning was higher than the criterion of 70% with a statistically significant level of .01.
