AbstrakPenelitian ini bertujuan untuk meningkatkan kemampuan komunikasi matematis siswa melalui pembelajaran matematika realistik. Metode penelitian yang digunakan adalah penelitian tidakan kelas yang meliputi tahap perencanaan, pelaksanaan, pengamatan dan refleksi. Subjek penelitian adalah siswa kelas VII-1 SMP Negeri 3 Padangsidimpuan dengan jumlah siswa 26 orang. Objek penelitian adalah kemampuan komunikasi matematis siswa yang diberi pembelajaran matematika realistik pada materi bilangan pecahan. Hasil  penelitian menunjukkan  bahwa penerapan pembelajaran  matematika realistik memberikan  dampak  positif  terhadap  peningkatan  kemampuan komunikasi matematis siswa yang  ditunjukkan  dengan peningkatan pada: 1)  Nilai rata-rata kemampuan komunikasi matematis siswa 79,79 pada siklus I dan 84,71 pada siklus II; 2) Aktivitas aktif siswa dalam pembelajaran dengan pembelajaran matematika realistik dikategorikan  efektif  yakni memperoleh  persentase  80%  pada siklus I dan 90% efektif pada siklus dua dengan kriteria keefektifan ≥ 80%; 3) Capaian ketuntasan kalasikal kemampuan komunikasi matematis siswa 73,08% pada siklus I dan 88,46% pada siklus II dengan nilai minimal ketuntasan klasikal 85%. Abstract (The Aplication of Realistic Mathematics Educations to Improve students’ mathematical communication Skills)This study aims to improve students' mathematical communication skills through realistic mathematics education. The research method used is classroom action research which includes the stages of planning, implementation, observation and reflection. The research subjects were students of class VII-1 of SMP Negeri 3 Padangsidimpuan with a total of 26 students. The object of research is the mathematical communication skills of students who are given realistic mathematics education on fraction material. The results showed that the application of realistic mathematics education had a positive impact on the improvement of students 'mathematical communication skills as indicated by an increase in: 1) The average value of students' mathematical communication skills was 79.79 in cycle I and 84.71 in cycle II; 2) The active activity of students in learning with realistic mathematics learning is categorized as effective, namely obtaining 80% percentage in the first cycle and 90% effective in the second cycle with the effectiveness criteria ≥ 80%; 3) Achievement of Kalasikal completeness of students' mathematical communication skills is 73.08% in cycle I and 88.46% in cycle II with a minimum grade of 85% classical completeness.
