Abstract: The Enhancement of Student’s Mathematical Communication Ability Through The Use of Open Ended Approach in Mathematic Learning in Elementary School. This study is back grounded by the importance of mathematical communication ability to be possessed by each student. One of method is by Open-Ended method. This study aim to obtain empirical proof about the use of open ended approach to enhance mathematical communication ability of Elementary School students. Research design use One-Group Pretest-Posttest Design experiment. Data analysis is done quantitatively for result of pretest, posttest, and normalized n-gain value. Based on data analysis in this study, it is concluded that: there is average enhancement of student’s mathematical communication ability after they get learning through the use of open ended approach, there is average enhancement of student’s open ended ability in doing mathematics problems, there is significant influence in mathematic learning process and student’s activity in the time of process. Mathematic learning through the use of open ended approach show positive value and active thinking.

Abstrak: Peningkatan Kemampuan Komunikasi Matematika Siswa Melalui Penggunaan Pendekatan Open Ended Dalam Pembelajaran Matematika Di Sekolah Dasar. Penelitian ini dilatar belakangi atas dasar pentingnya kemampuan komunikasi matematika untuk dimiliki setiap siswa. Salah satu metodenya yaitu dengan metode Open-Ended. Penelitian ini bertujuan untuk memperoleh bukti empiris tentang penggunaan pendekatan open ended untuk meningkatkan kemampuan komunikasi matematika siswa SD. Desain penelitian menggunakan eksperimen One-Group Pretes-Postes Design. Analisis data dilakukan secara kuantitatif untuk hasil pretes, postes, dan nilai n-gain ternormalisasi. Berdasarkan analisis data dalam penelitian ini, maka untuk kesimpulan bahwa, meningkatnya rata-rata kemampuan komunikasi matematika siswa setelah adanya pembelajaran melalui penggunaan pendekatan open ended, meningkatnya rata-rata kemampuan open ended siswa dalam mengerjakan soal-soal matematika, adanya pengaruh yang signifikan dalam proses pembelajaran matematika dan aktivitas siswa pada saat proses. Pembelajaran matematika melalui penggunaan pendekatan open ended menunjukkan nilai yang positif dan berpikir aktif.
