Penelitian ini bertujuan untuk (1) meningkatkan kemampuan komunikasi matematika dan (2) mengetahui tanggapan siswa terhadap model pembelajaran Problem Based Learning berbantuan media online. Jenis penelitian ini adalah penelitian tindakan kelas yang melibatkan 40 orang siswa kelas VIII 9 SMP Negeri 2 Singaraja pada semester genap tahun ajaran 2013/2014 yang dilaksanakan dalam tiga siklus. Data kemampuan komunikasi siswa dikumpulkan dengan menggunakan tes kemampuan komunikasi matematika dan tanggapan siswa dikumpulkan dengan menggunakan angket. Data yang telah dikumpulkan selanjutnya dianalisis secara deskriptif. Hasil penelitian menunjukkan penerapan model pembelajaran Problem Based Learning berbantuan media online mampu meningkatkan kemampuan komunikasi matematika siswa. Pada siklus I diperoleh presentase kemampuan komunikasi matematika siswa, yaitu 54,65% (dalam kategori kurang). Pada siklus II nilai presentase kemampuan komunikasi matematika siswa meningkat menjadi 60,22% (dalam kategori cukup). Pada siklus III presentase kemampuan komunikasi matematika siswa meningkat menjadi 76,59% dalam kategori baik (sudah memenuhi indikator keberhasilan penelitian yang ditetapkan). Tanggapan siswa setelah diterapkan model Problem Based Learning berbantuan media online tergolong positif.Kata Kunci : model pembelajaran Problem Based Learning berbantuan media online, kemampuan komunikasi matematika, tanggapan siswa
This research was aimed to (1) improve the students' mathematical communication ability and (2) determine the students' response toward the implementation of Problem Based learning assisted online media. This research was an action research which was conducted in three cycles and involved 40 students of VIII 9 class of SMPN 2 Singaraja in the academic year 2013/2014. The data was collected through questionnaires. The data found was analyzed descriptively. The result showed that the implementation of problem based learning assisted online media could improve the students' mathematical communication ability. In cycle 1, the percentage of the students' mathematical communication ability was 54.65%. In cycle 2, the percentage was improved into 60.22%. Meanwhile in cycle 3, the percentage was improved into 76.59%. The students' responses after the approach was implemented were positive.
