Menurut Van Hiele dalam memberikan pembelajaran geometri, penting bagi guru dalam memahami level berpikir geometri siswa. Level berpikir geometri siswa menurut Van Hiele terdiri dari 5 level, yakni level 1 (visualisasi), level 2 (analysis), level 3 (informal deduction), level 4 (Deduction), level 5 (Rigor). Level berpikir geometri siswa juga dapat ditingkatkan dengan suatu pembelajaran geometri dengan teori Van Hiel yang terdiri dari 5 tahap, yaitu (l) inquiry, (2) orientasi terarah(directed orientation), (3) explanation, (4) free orientation, (5) integration. Mempelajari geometri di sekolah juga penting bagi siswa tunanetra. Penelitian ini merupakan penelitian kualitatif deskriptif dengan jenis studi kasus yang mengukur level berpikir geometri 6 siswa tunanetra di SLB Negeri Bandung kelas VIII pada materi bangun datar. Setelah mengetahui level berpikir geometri siswa, diadakan pembelajaran geometri dengan teori Van Hiele untuk meningkatkan level berpikir geometri siswa. Hasil dari penelitian ini adalah terjadi peningkatan level berpikir geometri pada keenam siswa. Siswa 1, 2, dan 3 meingkat dari level 1 menjadi level 3, Siswa 5 meningkat dari level 0 menjadi level 2, dan Siswa 6 meningkat dari level 0 menjadi level 1. ---------- According to Van Hiele in providing learning geometry, it is important for teachers to understand the level of thinking geometry students. Level think students according to Van Hiele geometry consists of 5 levels, ie, level 1 (visualization), level 2 (analysis), level 3 (informal deduction), level 4 (Deduction), level 5 (Rigor). Level think geometry students can also be enhanced with a learning geometry with the theory of Van Hiele which consists of 5 stages, namely (l) inquiry, (2) the orientation of directional (directed orientation), (3) explanation, (4) free orientation, (5 ) integration. Studying geometry in school is also important for blind students. This research is qualitative descriptive case study that measures the level of thinking geometry 6 blind students in Bandung SLB class VIII on the material flat wake. After knowing the students 'level of thinking geometry, geometry learning held by the Van Hiele theory to improve the students' level of thinking geometry. Results of this study was an increase in the level of geometry in the sixth student thinking. Students 1, 2, and 3 meingkat from level 1 to level 3, students 5 increased from level 0 to level 2, and 6 students increased from level 0 to level 1.
