Geometry is a branch of mathematics that many applications in everyday life, but thestudent’s understanding of geometry tend to be low. Understanding the conceptof geometry put forward the process of geometric thinking. In Van Hiele's theory,geometric thinking is formulated into five levels of thinking that is level 0 (visualization), level 1 (analysis), level 2 (informal deduction), level 3 (deduction),and level 4 (rigor). This study aims to determine which level of student thinkingbased on Van Hiele theory in terms of reflective-impulsive cognitive style.Thisresearch is descriptive qualitative research. The subjects of the study were thestudents of class VIII E SMP Negeri 4 Yogyakarta consisting of two students ofreflective cognitive style and 3 students of cognitive impulsive style. Techniques ofcollecting data used tests (TLB) and interviews. Research instruments include MFFT to map students 'cognitive and TLB styles to determine students' level of thinking.Data analysis using Milles and Hubermanmodel.The results showed that thestudents' cognitive style tendency was dominated by reflective and impulsivecognitive style that was 69,69%. Based on TLB's written results and interviews show that the reflective or impulsive subjects are at level 2 (informal deduction). This suggests that the different of cognitive style do not cause differences in thinking levels based on Van Hiele's theory. Keywords: Thinking Level,Van Hiele Theory, Reflective-Impulsive

Setiap siswa terlahir dengan karakteristik unik yang melekat pada dirinya termasuk gaya kognitif. Siswa dalam satu kelas tentu memiliki bermacam-macam tipe gaya kognitif. Perbedaan tipe gaya kognitif tersebut dapat menyebabkan perbedaan dalam hal kemampuan matematika. Salah satu kemampuan dasar matematika yang harus dimiliki oleh seorang siswa adalah kemampuan koneksi matematika. Penelitian ini bertujuan mendeskripsikan profil kemampuan koneksi matematis siswa SMP Muhammadiyah 1 Gamping kelas VIII yang bergaya kognitif Reflektif-Impulsif dalam menyelesaikan soal Geometri. Penelitian ini menggunakan pendekatan kualitatif deskriptif. Subjek penelitian ini adalah 2 orang siswa kelas VIII SMP Muhammadiyah 1 gamping yang masing-masing bergaya kognitif refleksif dan impulsif. Adapun penentuan gaya kognitif siswa menggunakan Matching Familiar Figures Test (MFFT). Teknik pengumpulan datanya menggunakan tes kemampuan komunikasi matematika (TKKM) dan wawancara. Analisis data dalam penelitian ini menggunakan model Milles dan Huberman. Sedangkan untuk mendapatkan data penelitian yang konsisten digunakan triangulasi waktu. Hasil penelitian menunjukkan bahwa dalam mengerjakan masalah yang diberikan subjek Reflektif memiliki kemampuan koneksi matematis yang lebih baik dari pada subjek impulsif. Subjek refleksif mampu mengenali dan menggunakan hubungan antar ide-ide dalam matematika, memahami bagaimana ide dalam matematika saling berhubungan dan membangun satu sama lain untuk menghasilkan suatu kesatuan yang utuh, mengenali dan mengaplikasikan matematika ke dalam lingkungan di luar matematika. Sedangkan subjek Impulsif belum sepenuhnya mampu mengenali dan menggunakan hubungan antar ide-ide dalam matematika, belum menunjukkan bahwa ia memahami bagaimana ide dalam matematika saling berhubungan dan membangun satu sama lain untuk menghasilkan suatu kesatuan yang utuh. Lebih lanjut lagi, Subjek Impulsif belum sepenuhnya mampu mengenali dan mengaplikasikan matematika ke dalam lingkungan di luar matematika.
