Abstract

Mathematical reasoning ability is a very important aspect in learning mathematics. This ability is a high-level ability that involves imagination and curiosity to think logically. Mathematical reasoning can be sharpened using the Problem Based Learning learning model, so this research was conducted to analyze the mathematical reasoning abilities of students at SMP Negeri 5 Kisaran using a qualitative descriptive approach. The subjects in this research were 32 students. The data used is written test results and observation results during the learning process which will then be analyzed using qualitative descriptive data analysis techniques including data reduction, data display and verification. The results of this research show that the mathematical reasoning ability of students in the high category is 8 people, 16 people are medium and 8 people are low, and the average value of the results of observations of mathematics learning activities in comparative material is 16.28125 with a percentage of 66.5%. which is included in the medium category. These results indicate that the reasoning abilities of students at SMP Negeri 5 Kisaran are in the medium category.

Abstract

The purpose of this study was to determine the results of increasing students' interest in learning mathematics on the material of building space by using the Problem Basset Learning (PBL) learning model. This research uses the method of classroom action research (PTK) or action research. According to Arikunto (2010: 1). Classroom action research is research that describes the cause-and-effect of treatment, as well as describes what happens when treatment is given, and describes the entire process from the beginning of the treatment to the impact of the treatment. The subjects used in this study were students of class VII-2 SMP N 5 Kisaran with a total of 32 students. The data in this study are test results and observation results. The results showed that using the PBL (Problem Based Learning) model can increase students' interest in learning mathematics on the material of building space. In cycle I consisting of 32 students, where 25 students (78%) in class VII-2 have increased students' interest in learning mathematics, while in cycle II with 29 students (91%) has greatly increased students' interest in learning while only 3 students (9%) still have not increased their interest in learning mathematics.
