IMPROVING STUDENTS' MATHEMATICAL COMMUNICATION SKILLS AND LEARNING OUTCOMES USING GEOGEBRA- ASSISTED THINK PAIR SHARE LEARNING MODEL

Abstract

This study was motivated by the observation of students' low mathematical communication skills, which consequently led to poor mathematics learning outcomes. The primary aim of this research is to investigate the enhancement of students' mathematical communication skills and learning outcomes through the implementation of the Think Pair Share (TPS) learning model, supplemented with GeoGebra software, in the context of Grade VIII students at SMP Negeri 24 Kerinci. The research employed Classroom Action Research (CAR) methodology, structured into two cycles. In the first cycle, the findings indicated an average student score improvement to 68.35 with a learning completeness rate of 65%, while the students' average mathematical communication skills were rated at 73.65. In the second cycle, there was a further increase in the average score to 77.55, with a learning completeness rate of 85%, and the students' mathematical communication skills averaged 77.1. These results demonstrate that the application of the Think Pair Share learning model, enhanced by GeoGebra, significantly improves both mathematical communication skills and overall mathematics learning outcomes for Grade VIII students at SMPN 24 Kerinci. This study underscores the effectiveness of integrating collaborative learning strategies and technological tools in enhancing students' academic performance in mathematics.
