Daftar Isi:
- Penelitian ini bertujuan untuk mengetahui perbedaan yang signifikan kemampuan pemecahan masalah matematika antara kelompok siswa yang dibelajarkan dengan model problem based learning (PBL) dan kelompok siswa yang dibelajarkan dengan model pembelajaran konvensional pada siswa kelas III di Gugus III Kecamatan Sukasada Kabupaten Buleleng Tahun Pelajaran 2016/2017. Jenis Penelitian ini adalah penelitian eksperimen semu dengan rancangan non-equivalent post-test only control group design. Populasi penelitian ini adalah seluruh siswa kelas III di Gugus III Kecamatan Sukasada Kabupaten Buleleng Tahun Pelajaran 2016/2017. Sampel diambil dengan cara random sampling. Sampel penelitian ini yaitu siswa kelas III SDN 2 Padangbulia dan siswa kelas III SDN 3 Pegadungan. Data kemampuan pemecahan masalah matematika siswa dikumpulkan menggunakan tes uraian. Data yang diperoleh dianalisis dengan menggunakan statistik deskriptif dan statistik inferensial. Hasil penelitian menunjukkan bahwa hasil analisis uji-t diperoleh thitung lebih besar dibandingkan dengan ttabel (thitung 15,76 > ttabel 2,021) ini berarti bahwa terdapat perbedaan yang signifikan kemampuan pemecahan masalah matematika antara kelompok siswa yang dibelajarkan dengan model problem based learning (PBL) dan kelompok siswa yang dibelajarkan dengan model konvensional, sehingga dapat disimpulkan bahwa model problem based learning (PBL) berpengaruh positif terhadap kemampuan pemecahan masalah matematika siswa kelas III di Gugus III Kecamatan Sukasada, Kabupaten Buleleng Tahun Pelajaran 2016/2017.Kata Kunci : kemampuan pemecahan masalah, Model PBL This research aims to determine the significant differences in the ability of problem solving of mathematics outcomes among groups of students that learned with model of problem based learning (PBL) and group of students that learned with conventional learning models to students third grade in cluster III Sukasada district Buleleng regency in the academic year 2016/2017. This research is a quasi-experimental with non-equivalent post-test only control group design. The population of this study was all students in three grade in cluster III Sukasada district Buleleng regency in the academic year 2016/2017. Samples were taken by random sampling. The sample of this research is the third grade students of SDN 2 Padangbulia and third grade students of SDN 3 Pegadungan. The students' math problem solving data were collected using a description test. The data obtained were analyzed using descriptive statistics and inferential statistics. The result of this research shows that the result of t-test analysis obtained tcount is bigger than ttable (tcount 15,76> ttable 2.021). This means that there are significant difference of problem solving ability of mathematics between group of students who are learning with problem based learning (PBL) model and Groups of students that learned with conventional learning models, So it can be concluded that the problem based learning model (PBL) has a positive effect on the ability of solving the problem of mathematics of third grade in cluster III Sukasada district Buleleng regency in the academic year 2016/2017.keyword : problem-solving ability, PBL Model
