Abstract
Penelitian ini bertujuan untuk meningkatkan kemampuan komunikasi matematis siswa kelas IX-H SMPN 5 Mataram materi pokok persamaan dan fungsi kuadrat dengan pendekatan saintifik tahun ajaran 2018/2019. Penelitian tindakan kelas ini terdiri dari 2 siklus, menggunakan model Kemmis & Taggart yang terdiri dari: perencanaan, pelaksanaan, observasi, dan refleksi. Siklus 1 terdiri dari 3 kali pertemuan, dan siklus 2 terdiri dari 4 kali pertemuan. Hasil penelitian menunjukkan bahwa adanya peningkatan aktivitas belajar siswa, siklus 1 berkategori aktif, dan siklus 2 berkategori sangat aktif. Nilai rata-rata kemampuan komunikasi matematis pada siklus 1 adalah 68,05 dengan ketuntasan belajar klasikal sebesar 26,32 % dan pada siklus 2 adalah 71,38 dengan ketuntasan belajar klasikal sebesar 52,63%. Ketuntasan belajar klasikal belum memenuhi indikator kinerja, karena kurang dari 85% siswa yang memperoleh nilai ââ°Â¥70 disetiap akhir siklus.References
