THE EFFECTS OF USING LEARNING ACTIVITY ON MATHEMATIZING PROCESS UPON MATHEMATICAL PROBLEMSOLVING ABILITY AND MATHEMATICAL COMMUNICATION ABILITY ON THE APPLICATION OF LINEAR EQUATION FOR GRADE 7 STUDENTS PRASARNMIT DEMONSTRATION SCHOOL (SECONDARY)

Abstract

The purposes of this study were: 1) to compare students’ mathematical problem solving ability of seventh grade students before and after administrating mathematizing process. 2) to compare students’ mathematical problem solving ability after administrating mathematizing process with the criterion of seventy percent. 3) to compare students’ mathematical communication ability before and after administrating mathematizing process. 4) to compare students’ mathematical communication ability after administrating mathematizing process with the criterion of seventy percent. The experimental method is One - Group Pretest - Posttest Design. The sample of this study included 30 of seventh grade. They were selected via cluster random sampling. The findings of this study were as follows: 1) mathematical problem solving ability of the students after experiencing mathematizing process were higher than before experiencing the treatment statistically significant at a level of .05. 2) mathematical problem solving ability of the students after experiencing mathematizing process were higher than the criterion of seventy percent statistically significant at a level of .05 3) mathematical communication ability of the students after experiencing mathematizing process were higher than before experiencing the treatment statistically significant at a level of .05. 4) mathematical communication ability of the students after experiencing mathematizing process were higher than the criterion of seventy percent statistically significant at a level of .05
