ANALISIS KEMAMPUAN PEMAHAMAN KONSEP SISWA PADA MATERI PERSAMAAN DAN PERTIDAKSAMAAN LINEAR DITINJAU DARI NORMA SOSIOMATEMATIS DI SMA MUHAMMADIYAH BANGKINANG KOTA

Abstract

This study aims to analyze students' conceptual understanding of linear equations and inequalities in terms of sociomathematical norms. The background of this research is based on the importance of conceptual understanding in mathematics learning and the role of sociomathematical norms as part of the classroom social environment that influences students' learning processes. This study employs a descriptive qualitative approach with six tenth-grade students from SMA Muhammadiyah Bangkinang Kota, selected through purposive sampling based on high, medium, and low categories derived from the sociomathematical norms questionnaire. The research instruments consisted of a questionnaire, written test, and semi-structured interviews. The findings show that students with high sociomathematical norms tend to have better conceptual understanding, as evidenced by their ability to restate concepts, classify objects, provide examples and non-examples, correctly apply mathematical procedures, and implement concepts in real-world contexts. In contrast, students with low sociomathematical norms struggle to understand and apply concepts accurately. These findings indicate that sociomathematical norms significantly contribute to students' conceptual understanding in mathematics.
