Abstract

Thinking skills are very important in learning mathematics because, with the help of mathematical reasoning, students can develop their thinking skills in mathematics. This research aims to improve students' mathematical reasoning abilities by using a project-based learning model (PjBL). This study uses a quantitative approach with a pre-experimental design, designed in a one-group pretest and posttest design. The population in this study were all students of SMP AW 8 (UNIVA) Medan which consisted of five classes. The research sample consisted of one class, namely class fourth with a total of 12 students selected by simple random sampling. Data collection techniques use students' mathematical reasoning abilities in the form of descriptive questions. The instrument used is a mathematical reasoning test consisting of pretest and posttest questions which will be used after testing the validity, reliability, level of difficulty, and discriminating power. The data analysis technique used to test the hypothesis is a paired sample t-test to find differences in students' mathematical reasoning abilities in the research class and get points to determine the increase in students' mathematical reasoning abilities. The results of the analysis using the sample t-test were obtained with a value of t_count = -27.735 <t_table = -2.20 indicating that students' mathematical reasoning abilities increased by using the project-based learning (PjBL) learning model. Students' mathematical reasoning ability increased in high class with an average score of 0.71

Abstract

Pendidikan merupakan hal yang sangat penting sebagai upaya untuk meningkatkan kualitas sumber daya manusia. Kemampuan berpikir kritis mendasari kemampuan berpikir tingkat tinggi termasuk di dalamnya berpikir kreatif pemecahan masalah dan pengambilan Keputusan sehingga wajib dikuasai terlebih dahulu. Kemampuan pemahaman matematis adalah kemampuan peserta didik yang dapat memahami suatu konsep dengan baik. Tujuan Penelitian ini adalah untuk menganalisis kemampuan berpikir kritis dan pemahaman matematis siswa dalam menyelesaikan soal system persamaan linear dua variable (SPLDV). Penelitian ini dilaksanakan di MTS EX PGA UNIVA dengan menggunakan metode adalah metode deskriptif kualitatif. Teknik pengumpulan data yang digunakan dalam penelitian ini yaitu Teknik tes dan non tes. Instrumen penelitian meliputi instrument tes : kemampuan awal matematis, kemampuan berpikir kritis, intrumen tes pemahaman matematis, dan pedoman wawancara. Hasil Penelitian menunjukkan adanya interaksi berkelanjutan antar guru dan siswa, secara data hasil nilai yang diperoleh siswa pada test awal mengalami peningatan setelah siswa di mendapatkan pembelajaran dengan model pemahaman matematis siswa, dimana nilai awal siswa sebelum melakukan pendekatan ini, nilai rata-rata siswa hanya 69,42 setelah melakukan pendekatan model pembelajaran pemahaman matematis siswa meningkat menjadi 80,76,berarti bahwa Model pembelajaran Pemahaman matematis siswa berpengaruh terhadap terhadap kemampuan berpikir kritis siswa.
