PENERAPAN MODEL PEMBELAJARAN PBL (PROBLEM BASED LEARNING) UNTUK MENINGKATKAN KONEKSI MATEMATIS SISWA KELAS VII

This study aims to determine whether there is a difference in mathematical connection ability before and after learning the PBL model and determine the improvement of students' mathematical connection ability through learning the PBL model. The research approach is a quantitative approach. While the type of research is descriptive with one group pretest-posttest design. The sample in this study was 30 students in grade VII-I SMP Negeri 2 Nglegok. Data analysis techniques were obtained by pretest and posttest students' mathematical connection skills. Data testing using SPSS version 24. Based on the results of the t-test, a significance of (0.000) < a(0.05) was obtained. This means H_0will be rejected, so it is concluded that there is a difference in students' mathematical connection ability to the application of the PBL learning model in class VII-I SMP Negeri 2 Nglegok on the revival material. Furthermore, based on the results of the N-Gain test, a mean value of 0.7492 > 0.7 was obtained so that it was included in the High category. Based on the Mean N-Gain Score Percent value, the result shows 74.9244 which is in the range of 56%-75% so it is included in the category of quite effective. Therefore, it can be concluded that the application of the PBL (problem based learning) learning model can improve the mathematical connection of students in grade VII-I SMP Negeri 2 Nglegok.
