IMPROVING MATHEMATICAL PROBLEM SOLVING ABILITY USING GEOGEBRA LEARNING MEDIA ON SMPN 4 MUARO JAMBI STUDENTS

This study aims to describe the improvement of mathematical problem solving skills using Geogebra learning media for students of SMP Negeri 4 Muaro Jambi, and identify the difficulties experienced by students in solving mathematical problem solving skills test questions. This research is motivated by the problem of students who still consider mathematics as a complicated lesson, difficulty in applying mathematical concepts, and learning that is still monotonous with limited learning media. This research is a quantitative study with research data obtained based on pretest and posttest results in both sample classes. This study also applied the Nonequivalent Control Group Design design with a population of VIII grade students of SMP Negeri 4 Muaro Jambi, with samples obtained based on saturated sample selection techniques. Data analysis in this study began with validating the research instrument in the form of test questions, and continued with hypothesis testing. The results showed that the use of Geogebra learning media was effective in improving students' mathematical problem solving skills, as evidenced by the rejection of H₀ and acceptance of H₁. The experimental class showed a moderate improvement with an average pretest of 10.31 increasing to 45.27 on the posttest and an n-gain value of 65%, while the control class obtained an average pretest of 7.6 increasing to 31 on the posttest with an n-gain of 42%.
