DEVELOPMENT OF MATHEMATICS LEARNING ACHIEVEMENT ON PROBLEMS-SOLVING ABILITY IN LINEAR INEQUATITY WITH ONE VARIABLE FOR GRADE-9 STUDENTS THROUGH THE USE OF ACTIVE LEARNING

Abstract

The objectives of this research are 1) to compare mathematics academic achievement on solving problems related with linear inequalities with one variable; grade-9 students before and after receiving active learning. 2) to compare mathematics academic achievement on solving problems related with linear inequalities with one variable; grade-9 students after receiving active learning with the 70 percentages threshold. The sample group used in this research was grade-9 students. Semester 1, academic year 2023, 1 classroom. There were 35 students, which were obtained by random sampling (Cluster Random Sampling). By using the classroom as the unit of sampling (Sampling Unit). Research instruments consisted of an active learning plan on solving problems related with linear inequalities with one variable and an academic achievement test on solving problems about linear inequalities in one variable. statistics used in data analysis included percentage, mean, standard deviation and t-test.
The research findings exposed that 1) Mathematics learning achievement on solving problems related to linear inequalities with one Variable; grade-9 students after receiving active learning was higher than before receiving active learning. Statistically significant at the .05 level. 2) Mathematics achievement scores on solving problems with linear inequalities with one variable; grade-9 students who received active learning above the 70 percentages threshold. Statistical significance at the .05 level.
