Abstract

Pembelajaran matematika yang terjadi selama ini belum memfasilitasi siswa untuk mengembangkan kemampuan representasi matematisnya. Kemampuan representasi matematis siswa dapat ditinjau dari berbagai dimensi, salah satunya yaitu gaya kognitif. Gaya kognitif mempengaruhi siswa dalam memahami materi dan permasalahan. Selain itu, disposisi matematis sebagai salah satu kompetensi sosial juga perlu dikembangkan agar siswa gigih dalam menyelesaikan masalah, menyukai matematika, dan dapat belajar dengan penuh tanggung jawab. Penelitian ini bertujuan untuk mengembangkan perangkat pembelajaran open-ended berbasis etnomatematika ditinjau dari gaya kognitif siswa untuk meningkatkan kemampuan representasi matematis dan disposisi matematis siswa yang layak digunakan. Berdasarkan uji validitas yang dilakukan oleh ahli, diperoleh nilai silabus yaitu 3,63, RPP sebesar 3,71, modul sebesar 3,74, ADM sebesar 3,86, TRM sebesar 3,83, dan pedoman wawancara sebesar 3,80. Seluruh perangkat pembelajaran dan instrumen tes termasuk pada kriteria sangat baik. Berdasarkan hasil tersebut maka disimpulkan bahwa perangkat pembelajaran open-ended berbasis etnomatematika ditinjau dari gaya kognitif siswa valid digunakan untuk meningkatkan kemampuan representasi dan disposisi matematis siswa. Kata kunci: disposisi matematis, gaya kognitif, open-ended, perangkat pembelajaran, representasi matematis. ABSTRACT Mathematics learning so far has not facilitated students to develop their mathematical representation ability. The students' mathematical representation ability can be reviewed from various dimensions, one of them is cognitive style. Cognitive style affects the students in understanding the material and the problems. Moreover, mathematical disposition as one of social competence also needs to be developed so the students persevere in solving problems, like mathematics, and can learn with full of responsibility. The purpose of this study was to develop an open-ended learning instrumens based on ethnomatematics in terms of students' cognitive style to improve mathematical representation and mathematical disposition of students which are eligible to use. Based on validity test conducted by the expert, the values of obtained syllabus, lesson plan, module, ADM, TRM, and interview guidance respectively are 3.63, 3.71, 3.74, 3.86, 3.83, and 3.80. All of learning and test instrumens included on very good criteria. Based on these results, the open-ended learning instrumens based on ethnomatematics in terms of the cognitive style of students valid to be used to improve students' mathematical representation and disposition. Keywords: mathematical disposition, cognitive style, open-ended, learning instrumens, mathematical representation.
