The Effectiveness of Project Based Learning in Improving Students’ Mathematics Problem Solving Ability

Abstract

The Effectiveness of Project Based Learning in Improving Students’ Mathematics Problem Solving Ability. Objectives: The aim of this research was to describe mathematics learning with the Project Based Learning model on mathematical problem solving abilitties in class X SMA N 1 Simo. Methods: In this quantitative study, two classes were taken as research subjects consisting of thirty-six students in each class, namely class X MIPA 4 and X MIPA 5. Data collection techniques was carried out with a written test of 7 essay questions that had been declared valid and reliable as well as documentation. Findings: The average of the experimental class with the PjBL learning model is 84.72 while the average of the control class with the conventional learning model is 65.53. Conclusions: The result of this research indicate that class X MIPA 5 with project based learning model treatment has better problem solving ability than class X MIPA 4 which is treated with conventional learning model. Keywords: Project based learning model, mathematical problem solving ability. Abstrak: Efektivitas Pembelajaran Berbasis Proyek dalam Meningkatkan Kemampuan Pemecahan Masalah Matematika Siswa. Tujuan: Penelitian ini bertujuan untuk mendeskripsikan Pembelajaran matematika dengan model Project Based Learning terhadap kemampuan pemecahan masalah matematika pada siswa kelas X SMA N 1 Simo. Metode: Dalam penelitian kuantitatif ini mengambil dua kelas sebagai subjek penelitian yang terdiri dari tiga puluh enam siswa setiap kelasnya yaitu kelas X MI3PA 4 dan X MIPA 5. Teknik pengumpulan data dilakukan dengan tes tertulis 7 soal essay yang telah dinyatakan valid dan reliabel serta dokumentasi. Temuan: Rerata dari kelas kelas eksperimen dengan model pembelajaran PjBL adalah sebesar 84,72 sedangkan rerata dari kelas kontrol dengan model pembelajaran konvensional adalah sebesar 65,53. Kesimpulan: Hasil penelitian ini menunjukkan kelas X MIPA 5 yang diberi perlakuan model pembelajaran project based learning memiliki kemampuan pemecahan masalah lebih baik daripada kelas X MIPA 4 dengan perlakuan model pembelajaran konvensional. Kata kunci: Model pembelajaran project based learning, kemampuan pemecahan masalah matematika. DOI: http://dx.doi.org/10.23960/jpp.v12.i2.202225
