Abstract

Penelitian ini dilatar belakangi oleh rendahnya kemampuan representasi matematis siswa kelas VII SMP Negeri 1 Bangkinang. Salah satu solusi untuk mengatasi masalah ini adalah dengan menggunakan model pembelajaran Concept Mapping. Penelitian ini bertujuan untuk mengetahui ada atau tidak pengaruh model pembelajaran Concept Mapping terhadap kemampuan representasi matematis siswa kelas VII SMP Negeri 1 Bangkinang. Penelitian ini merupakan quasi eksperimental dengan menggunakan post- test control group design. Subjek penelitian terdiri dari kelas VII.A yang berjumlah 24 siswa dan VII.B yang berjumlah 24 siswa. Teknik sampel yang digunakan adalah simple random sampling. Teknik pengumpulan data yang digunakan yaitu lembar obsevasi dan soal tes kemampuan representasi matematis. Hasil penelitian ini dapat disimpulkan bahwa terdapat pengaruh model pembelajaran Concept Mapping terhadap kemampuan representasi matematis siswa kelas VII SMP Negeri 1 Bangkinang. Hal tersebut dapat dibuktikan melalui uji Independent Sample T-Test memperoleh nilai sig(2- tailed) 0,020 < 0,05 maka H0 ditolak dan Ha diterima.

Abstract

Objective: This study aims to examine the effect of implementing the Realistic Mathematics Education (RME) learning model on students’ mathematical problem-solving skills and mathematical communication abilities at SMP Negeri 1 Bangkinang Kota. The study emphasizes how context-based learning grounded in real-life situations can enhance students’ conceptual understanding, higher-order thinking skills, and their ability to communicate mathematical ideas systematically and effectively. Research Method: This study employed a quasi-experimental design using a Pretest–Posttest Control Group Design. The research sample consisted of 40 eighth-grade students of SMP Negeri 1 Bangkinang Kota, divided into two groups: an experimental group (20 students) taught using the RME model and a control group (20 students) taught using conventional mathematics instruction. Data were collected through a mathematical problem-solving test and a rubric-based assessment of mathematical communication skills. Data analysis was conducted using descriptive statistics and inferential statistics, specifically an independent samples t-test, after fulfilling the assumptions of normality and homogeneity. Research Findings: The results indicate a significant difference between the experimental and control groups in terms of mathematical problem-solving skills and mathematical communication abilities. The posttest scores of students in the experimental group were significantly higher than those of the control group. These findings demonstrate that the implementation of the RME model is effective in improving students’ mathematical problem-solving and communication skills. Novelty: This study clarifies the novelty of RME by explaining the classroom mechanism that integrates contextual problem exploration, group discussion, and student presentations. Through these processes, students simultaneously develop mathematical communication and problem-solving skills within collaborative and reflective learning activities.
