Abstract

Tujuan dalam penelitian ini adalah untuk mengetahui apakah peningkatan kemampuan pemecahan masalah mahasiswa dengan model Problem Based Learning (PBL) lebih baik dari pembelajaran langsung. Penelitian ini merupakan penelitian quasi experiment dengan rancangan pretest-posttest control group design. Sampel dalam penelitian ini adalah mahasiswa semester V kelas A dan B IKIP PGRI Pontianak dengan teknik cluster random sampling. Instrumen penelitian yang digunakan adalah soal tes kemampuan pemecahan masalah pada mata kuliah matematika diskrit. Hasil penelitian menunjukkan bahwa terdapat peningkatan kemampuan pemecahan masalah dimana pengujian hipotesis dengan menggunakan uji Mann-Whitney diperoleh nilai Asymp. Sig. (2-tailed) sebesar 0,000 lebih kecil dari 0,05 maka rata-rata kemampuan pemecahan masalah dengan menggunakan model PBL lebih besar daripada rata-rata kemampuan pemecahan masalah dengan menggunakan pembelajaran langsung. Dari hasil penelitian dapat disimpulkan bahwa mahasiswa yang pembelajarannya menerapkan pembelajaran dengan model PBL peningkatan kemampuan pemecahan masalah secara signifikan lebih baik dibandingkan dengan siswa yang pembelajarannya menggunakan pembelajaran langsung. The purpose of this study was to determine whether the increase in student problem solving abilities with the Problem Based Learning (PBL) model was better than direct learning. This research is a quasi experimental study with a pretest-posttest control group design. The sample in this study were the fifth semester students of class A and B IKIP PGRI Pontianak with cluster random sampling technique. The research instrument used was a test problem solving ability in discrete mathematics courses. The results showed that there was an increase in problem solving abilities where hypothesis testing using the Mann-Whitney test obtained Asymp. Sig. (2-tailed) of 0,000 less than 0,05, the average problem solving ability using the PBL model is greater than the average problem solving ability using direct learning. From the results of the study, it can be concluded thet students whose learning applies PBL model increase their problem solving abilities significantly better than students whose learning used direct learning.
