Abstract

Penelitian ini bertujuan untuk mengetahui : (1) Apakah peningkatan kemampuan pemecahan masalah matematis melalui Pembelajaran Berbasis Masalah lebih tinggi daripada siswa yang memperoleh pembelajaran ekspositori. (2) Apakah peningkatan motivasi belajar siswa melalui pembelajaran berbasis masalah lebih tinggi daripada siswa yang memperoleh pembelajaran ekspositori (3) Bagaimana proses jawaban dari siswa yang mendapatkan pembelajaran berbasis masalah dan siswa yang memperoleh pembelajaran ekspositori. Penelitian ini merupakan penelitian kuasi eksperimen. Populasi penelitian ini siswa SMP Negeri 28 Medan dan SMP Negeri 36 Medan. Pemilihan sampel dilakukan secara random dengan mengacak kelas. Instrumen yang digunakan terdiri dari: (1) tes kemampuan pemecahan masalah matematis dengan materi kubus dan balok (2) angket motivasi belajar siswa. Adapun tes yang digunakan untuk memperoleh data adalah berbentuk uraian. Data dalam penelitian ini dianalisis dengan menggunakan analisis statistik deskriptif. Analisis statistik data dilakukan dengan analisis uji-t. Hasil penelitian menunjukkan bahwa : (1) peningkatan kemampuan pemecahan masalah matematis yang melalui pembelajaran berbasis masalah lebih tinggi daripada siswa yang memperoleh pembelajaran ekspositori. Dimana indikator memahami masalah lebih tinggi dari ketiga indikator lainnya. (2) peningkatan motivasi belajar siswa yang melalui model pembelajaran berbasis masalah lebih tinggi daripada siswa yang memperoleh pembelajaran ekspositori. Dimana motivasi intrinsik lebih tinggi daripada motivasi ekstrinsik. (3) Proses penyelesaian jawaban siswa melalui pembelajaran berbasis masalah lebih baik dibanding dengan pembelajaran ekspositori. Hal ini dapat terlihat dari lembar jawaban siswa pada kelas eksperimen secara keseluruhan siswa pada kelas eksperimen dapat menyelesaikan soal dengan benar dan lengkap dibandingkan dengan siswa pada kelas kontrol dapat menyelesaikan soal dengan benar tetapi kurang lengkap dalam menyelesaikan kemampuan pemecahan masalah. Berdasarkan hasil penelitian ini, peneliti menyarankan agar pembelajaran berbasis masalah pada pembelajaran matematika dapat dijadikan alternatif bagi guru matematika untuk meningkatkan kemampuan pemecahan masalah matematis dan motivasi belajar siswa sebagai salah satu alternatif untuk menerapkan pembelajaran matematika yang inovatif.
