PENINGKATAN KEMAMPUAN KOMUNIKASI MATEMATIS SISWA SMP MELALUI MODEL PROBLEM BASED LEARNING BERBANTUAN GEOGEBRA

Abstract

The aims of this study were to: 1) Know the improvement in the mathematical communication abilities of students who received the Geogebra-assisted Problem Based Learning model was better than students who received conventional learning models. 2) Knowing the Self-confidence of students who get the Geogebra-assisted Problem Based Learning model is better than students who get conventional learning models. 3) Knowing that there is a correlation between mathematical communication ability and self-confidence of students who obtain the Geogebra-assisted Problem Based Learning model. The method used is quasi-experimental. The subjects in this study were students of SMPN 16 Bandung. Data analysis technique with a two-sample comparison test (t-test) using the IBM SPSS 23.0 for Windows software program. Based on the results of data analysis, the following conclusions are obtained: 1) Improved mathematical communication ability of students who get the Geogebra-assisted Problem Based Learning model are better than students who get conventional learning models. 2) Self-confidence of students who use the Geogebra-assisted Problem Based Learning model is better than students who receive conventional learning models. 3) There is a correlation between mathematical communication ability and self-confidence of students who obtain the Geogebra-assisted Problem Based Learning model.Tujuan dari penelitian ini untuk: 1) Mengetahui peningkatan kemampuan komunikasi matematis siswa yang memperoleh model Problem Based Learning berbantuan Geogebra lebih baik daripada siswa yang memperoleh model pembelajaran konvensional. 2) Mengetahui Self-confidence siswa yang memperoleh model Problem Based Learning berbantuan Geogebra lebih baik daripada siswa yang memperoleh model pembelajaran konvensional. 3) Mengetahui terdapat korelasi antara kemampuan komunikasi matematis dan Self-confidence siswa yang memperoleh model Problem Based Learning berbantuan Geogebra.  Metode yang digunakan yaitu kuasi eksperimen. Subjek dalam penelitian ini adalah siswa SMPN 16 Bandung. Teknik analisis data dengan uji perbandingan dua sampel (uji-t) menggunakan program software IBM SPSS 23.0 for windows. Berdasarkan hasil analisis data, diperoleh kesimpulan sebagai berikut: 1) Peningkatan kemampuan komunikasi matematis siswa yang memperoleh model Problem Based Learning berbantuan Geogebra lebih baik daripada siswa yang memperoleh model pembelajaran konvensional. 2) Self-confidence siswa yang model Problem Based Learning berbantuan Geogebra lebih baik daripada siswa yang memperoleh model pembelajaran konvensional. 3) Terdapat korelasi antara kemampuan komunikasi matematis dan Self-confidence siswa yang memperoleh model Problem Based Learning berbantuan Geogebr
