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
