Abstract
This study aims to determine (1) the mathematical communication ability of students taught by the gallery walk type cooperative learning model is higher than the mathematical communication skills of students taught by conventional learning models (2) student responses through the application of the gallery walk type cooperative learning model to communication skills. mathematics students of SMP Negeri 8 Padangsidimpuan. The research method used is quasi-experimental. The population of this study were all seventh grade students of SMP Negeri 8 Padangsidimpuan. Sampling using simple random sampling. The sample is class VII-2 as the experimental class and class VII-1 as the control class. Data collection using a mathematical communication ability test sheet.The results showed (1) t_(count )= 3.56 and t_(table )= 1.67 or) t_(count ) > t_(table ) so that it can be concluded that students' mathematical communication skills are taught by cooperative learning model type gallery walk is higher than the mathematical communication ability of students who are taught by conventional learning models. (2) Based on the results of student responses, an average score of 3.55 was obtained so that it can be concluded that student responses through the application of the gallery walk type cooperative learning model to the mathematical communication skills of SMP Negeri 8 Padangsidimpuan students were very positive.

Summary
Pendidikan memiliki peranan yang penting untuk meningkatkan kualitas serta kuantitas sumber daya manusia. Bertolak dari pentingnya peranan matematika dalam pendidikan, maka matematika perlu diajarkan karena melalui pembelajaran matematika siswa dilatih agar dapat berpikir kritis, kreatif, logis, sistematis, dan dapat menyelesaikan masalah dalam kehidupan sehari-hari. Berdasarkan hasil penelitian awal pada 32 siswa untuk melihat kemampuan komunikasi matematis siswa, diperoleh presentase skor kemampuan menggunakan bahasa matematika atau simbol sebesar 36,76,%. Mengingat bahwa pentingnya kemampuan komunuikasi matematika dalam pembelajaran matematika maka upaya yang dapat dilakukan guru adalah menerapkan model pembelajaran yang baik, yaitu pembelajaran yang tidak membosannya, pembelajaran yang tidak berpusat pada guru, tapi berpusat pada siswa, siswa sendiri yang menemukan permasalahan dan menyelesaikannya, guru hanya menjadi fasilitator. Dan peneliti mengambil model pembelajaran kooperatif tipe gallery walk untuk meningkatkan kemampuan komunikasi matematis siswa. Selain itu aspek dari komunikasi, bahwa pelajaran dapat membantu siswa untuk mengkomunikasikan ide-ide matematis dengan membaca, mendengar, berdiskusi, menulis dan mempresentasikan
