PENGARUH MODEL PROBLEM BASED LEARNING UNTUK MENINGKATKAN KEMAMPUAN PEMECAHAN MASALAH SISWA KELAS V MATA PELAJARAN MATEMATIKA SEKOLAH DASAR

Abstract

This research aims to determine the influence of the Problem-Based Learning (PBL) model on the problem-solving abilities of fifth-grade students in mathematics subjects in elementary schools. The instrument used in this research is a test of mathematical problem-solving abilities in the form of descriptions, with the material being taught being spatial shapes. The subjects in this research were all class students at SDN Ibu Dewi 3 Cianjur, while the sample in this research consisted of two classes. One class is the experimental class and the other class is the control class. The sample in the experimental class was 20 people, and the sample in the control class was also 20 people. From data analysis using a simple regression test, the average test of mathematical problem-solving ability in the experimental class before and after learning was 70.50 and 90.20. Meanwhile, the average control class mathematics problem-solving ability test before and after learning was 86.55 and 69.60. Hypothesis testing in this study used t- and F-tests which were carried out to determine the level of students' mathematical problem-solving abilities before and after being taught using the Problem Based Learning (PBL) learning model. Where the result of the constant is 61.935 while the value of the experimental class (X) is 0.085 with a significant value of 0.042 < 0.05, while the Fhitung test is 0.074 < Ftable 4.385 with a significance level of 0.789 > 0.05. Thus it can be concluded that there is an influence of the Problem learning model Based Learning (PBL) on the mathematical problem-solving abilities of fifth grade students at SDN Ibu Dewi 3 Cianjur.
