Data yang dikumpulkan, dianalisis dengan metode kualitatif dan statistik sederhana secara deskriptif. Instrumen yang digunakan adalah lembar observasi, lembar angket, dan rubrik. Adapun subjek penelitian adalah siswa kelas VIII SMP Lentera Harapan Way Pengubuan yang berjumlah 11 orang. Penelitian dilakukan pada 17 Juli 2017 sampai 04 Oktober 2017. Metode penelitian yang digunakan adalah Penelitian Tindakan Kelas (PTK).
Oleh karena itu, peneliti melakukan penelitian yang bertujuan untuk menyelidiki bagaimana implementasi metode drill meningkatkan kemampuan komunikasi matematis siswa.
Selain itu, siswa masih keliru dalam menuliskan persamaan dan simbol dengan tepat dan belum mampu menyajikan representasi visual berupa grafik berdasarkan pernyataan yang ada. Berdasarkan observasi yang dilakukan pada SMP Lentera Way Pengubuan, ditemukan bahwa siswa belum mampu menuliskan strategi penyelesaian suatu pernyataan atau pertanyaan sesuatu prosedur penyelesaian dengan tepat dan lengkap. Therefore, it could be concluded that the implementation of the drill method could increase students’ mathematical communication skills.BAHASA INDONESIA ABSTRAK: Kemampuan komunikasi matematis pada pembelajaran matematika penting untuk siswa mampu menyajikan strategi sebagai solusi akan pernyataan maupun pertanyaan sesuai dengan prosedur dan prinsip yang benar. The findings showed an increase in the indicators of students’ mathematical communication skills from the first cycle to the second cycle. The data gathered were analyzed using descriptive statistics and qualitative descriptive methods. Instruments used were observation sheet, questionnaire sheet, and rubric. The subjects of this research were 11 grade 8 students. The research was conducted from July 17, 2017 to October 4, 2017. The method used was Classroom Action Research (CAR). Therefore, the researcher implemented the drill method to enhance their mathematical communication skills. These indicated that students lacked in their mathematical communication skills. Students were also unable to draw the correct graphics equation. Several details were missed and some symbols and equations were inappropriately used. Based on observations at Lentera Harapan Way Pengubuan school, it was found that students were not able to write down the strategy to solve statements or questions with clear and complete procedures. Mathematical communication skills are important for students to be able to present strategies to solve questions with the right procedures and principles.
