Abstract

Penelitian ini bertujuan untuk meningkatkan kemampuan penalaran siswa melalui penerapan model Problem Based Learning pada materi barisan dan deret di kelas XI MIA SMA Negeri 1 Lubuk Pakam. Jenis penelitian ini adalah penelitian tindakan kelas. Subjek penelitian ini adalah siswa/i kelas XI MIA 1 SMA Negeri 1 Lubuk Pakam yang berjumlah 36 orang. Objek penelitian ini adalah upaya meningkatkan kemampuan penalaran siswa melalui model Problem Based Learning pada materi barisan dan deret di SMA Negeri 1 Lubuk Pakam Tahun Ajaran 2018/2019. Penelitian ini dikatakan berhasil jika memenuhi 3 indikator keberhasilan, yaitu: 1) Kemampuan penalaran siswa secara individu mencapai KKM (nilai ≥ 65) dengan kategori sedang; 2) Secara klasikal terdapat ≥ 85% ketuntasan belajar siswa); dan 3) Kemampuan guru dalam mengelola pelajaran mencapai interval 2,6  3,5 dengan kategori baik. Penelitian ini dilaksanakan dalam 2 siklus. Berdasarkan analisis data diperoleh hasil penelitian, yaitu: rata-rata kemampuan penalaran siswa pada siklus I sebesar 57,92 dengan persentase siswa yang telah mencapai KKM (nilai ≥ 65) sebesar 50% dan pada siklus II rata-rata kemampuan penalaran siswa meningkat menjadi 79,58 dengan persentase siswa yang telah mencapai KKM sebesar 91,67% dari jumlah siswa. Penerapan model Problem Based Learning juga meningkatkan kemampuan guru dalam mengelola pembelajaran. Hal ini dapat dilihat dari hasil observasi terhadap guru dalam mengelola pembelajaran yaitu pada siklus I kemampuan guru berada pada interval 1,6  2,5 dengan kategori kurang dan pada siklus II mengalami peningkatan menjadi 2,6  3,5 dengan kategori baik. Berdasarkan hasil penelitian tersebut dapat disimpulkan bahwa terjadi peningkatan kemampuan penalaran siswa kelas XI MIA 1 SMA Negeri 1 Lubuk Pakam sehingga pembelajaran dengan menerapkan model Problem Based Learning dapat dijadikan salah satu alternatif pembelajaran untuk meningkatkan kemampuan penalaran siswa.
