PERBANDINGAN MODEL PROBLEM-BASED LEARNING DAN DISCOVERY LEARNING TERHADAP PENINGKATAN KEMAMPUAN PEMECAHAN MASALAH MATEMATIS SISWA
Kemampuan pemecahan masalah matematis merupakan suatu kemampuan yang dimiliki oleh seseorang dalam memecahkan masalah yang bersifat matematika. Faktanya, berdasarkan hasil penelitian terdahulu diperoleh informasi kemampuan pemecahan masalah matematis siswa SMA di Indonesia masih rendah. Penelitian ini bertujuan untuk mengkaji perbandingan model problem-based learning dan discovery learning terhadap peningkatan kemampuan pemecahan masalah matematis siswa. Metode penelitian yang digunakan yaitu metode quasi experimental dengan desain the static group pretest-posttest design. Populasi pada penelitan ini adalah seluruh siswa kelas X di salah satu SMA Negeri di Kota Bandung dengan mengambil dua kelas sebagai sampel menggunakan purposive sampling, yaitu kelas X-7 sebagai kelas eksperimen 1 dan kelas X-8 sebagai kelas eksperimen 2. Kelas eskperimen 1 dan eksperimen 2 memiliki sampel sebanyak 32 siswa. Instrumen penelitian terdiri atas tes kemampuan pemecahan masalah matematis materi peluang. Hasil dari penelitian ini adalah : 1) Peningkatan kemampuan pemecahan masalah matematis siswa yang menerima perlakuan model problem-based learning lebih tinggi dibandingkan dengan siswa yang menerima model discovery learning. 2) Tidak terdapat pengaruh interaksi model pembelajaran dan kemampuan awal matematika terhadap peningkatan kemampuan pemecahan masalah matematis siswa. 3) Peningkatan kemampuan pemecahan masalah matematis kategori kemampuan awal matematika tinggi dan sedang model problem-based learning lebih tinggi dari model discovery learning. 4) Terdapat perbedaan peningkatan kemampuan pemecahan masalah matematis ketiga kategori kemampuan awal matematika di kelas model problem-based learning. 5) Tidak terdapat perbedaan peningkatan kemampuan pemecahan masalah matematis ketiga kategori kemampuan awal matematika di kelas model discovery learning. Mathematical problem solving ability is an individual's capability to solve mathematical problems. However, based on the results of previous studies, the mathematical problem solving ability of high school students in Indonesia is low. The purpose of this research is to compared of problem-based learning and discovery learning models to increase students' mathematical problem solving abilities. The research used quasi experimental method with the static group pretest-posttest design. The population of this research consists of all 10th-grade students in one of the high schools in Bandung City. Two classes were selected as samples using purposive sampling, X-7 class as the experimental group 1 and X-8 class as the experimental group 2. Both the experimental 1 and the experimental 2 groups had a sample size of 32 students. The research instruments consist of a mathematical problem solving ability test on the topic of probability. The results of this research are as follows: 1) The improvement in students' mathematical problem solving ability who received the treatment of the problem-based learning model was higher compared to students who received discovery learning. 2) There is no significant interaction effect between the teaching model and prior mathematical abilities on the improvement of students' mathematical problem solving skills.3) The improvement in students' mathematical problem solving ability with high and medium prior math abilities using the problem-based learning model is higher than the discovery learning model. 4) There were differences in the improvement of mathematical problem solving ability among the three categories of students' prior mathematics ability in the problem-based learning model. 5) There is no difference in the improvement of mathematical problem-solving ability among the three students’ prior mathematics ability categories in the discovery learning model classes.
