Pengaruh PBL Terhadap Kemampuan Numerasi Siswa Kelas VII SMP Negeri 4 Mataram pada Materi Statistika
Abstract
This study aims to determine whether or not there is an influence of PBL on the numeracy skills of class VII students of SMP Negeri 4 Mataram on statistics material in the 2024/2025 academic year and to describe the greatest contribution of PBL in improving numeracy skills. This study was motivated by the low numeracy skills of students, which were caused by the use of conventional learning models that were less effective, so that innovative learning strategies were needed according to student needs. This study uses a quantitative approach using a quasi-experimental method. The research design used was a pre-test post-test control group design. The subjects in this study were students in class VII-3 as an experimental class with 32 students and class VII-5 with 31 students as a control class. The data collection technique used a numeracy ability test given before and after treatment. Then the data obtained were analyzed using the Ancova test. The results showed that there was an influence of the PBL learning model, the average posttest score in the experimental class reached 77.2, while in the control class it was 67.5 which was significantly different. This means that there is an influence of the PBL model on the numeracy skills of class VII students of SMPN 4 Mataram which consists of 3 indicators, namely 1) Use of numbers and symbols, 2) Data analysis, 3) Interpretation of analysis results.References
