Perbandingan Kemampuan Komunikasi Matematis Siswa antara Problem Based Learning Dan Direct Instruction

Abstract

Mathematical communication skills possessed by students are still low, so it needs efforts to improve students' mathematical communication skills, one of which is using the Problem Based Learning (PBL) and Direct Instruction (DI) learning model. The purpose of this study was to analyze the comparison of mathematical communication skills between students who received PBL and DI learning models. The research method used was quasi-experimental with a population of all seventh-grade students of SMP Negeri 1 Tarogong Kaler Garut. The sample was selected based on the purposive sampling technique consisting of two classes, namely class VII-A as the experimental class I which received the PBL learning model, and class VII-B as the experimental class II which received the DI learning model. The research instruments used were descriptive tests and questionnaires. Based on the results of statistical analysis, it is concluded that the mathematical communication skills of students who get the PBL learning model are better than students who get the DI learning model with the interpretation of the increase in students 'mathematical communication skills from both classes with moderate interpretation and students' attitudes towards learning through the PBL and DI interpreted learning models. enough.
