“…The purpose of learning geometry at school as reported by Thomas [3], such (a) to develop spatial awareness, intuition and the ability to visualize geometry; (b) To provide the breadth of experience both in the geometry of two-dimensional space and 3-dimensional; (c) To develop knowledge and understanding and the ability to use the properties and geometry theorem; (d) to encourage the development and use of conjecture, deductive reasoning and evidence; (e) To develop the application of geometry skills through modeling and problem solving in the real world; (f) to develop the use of ICT skills in the context of geometry; (g) to ensure a positive attitude towards mathematics and; (h) to develop an awareness of the historical and cultural heritage of geometry in society and contemporary applications of geometry. However some testimony from the field showed that the results of learning geometry in Indonesia remain low because there are many students who have difficulty in learning geometry, ranging from elementary to university level [4] while Syahputra's [5] statement that students find many difficulties to understans object or image wake geometry.…”

“…Meanwhile, according to Budiarto stated that "the purpose of learning geometry is to develop the ability to think logically, develop spatial intuition, imparting knowledge to support other materials, and able to read and interpret mathematical arguments" [4]. Therefore, developing the students' spatial ability is important because it is one of the goals of learning geometry.…”

Abstract. The main purpose of this quasi-experimental study was to determine the enhancement of spatial ability of junior high school students who learned through Cabri-3D assisted collaborative learning. The methodology of this study was the nonequivalent group that was conducted to students of the eighth grade in a junior high school as a population. Samples consisted one class of the experimental group who studied with Cabri-3D assisted collaborative learning and one class as a control group who got regular learning activity. The instrument used in this study was a spatial ability test. Analyzing normalized gain of students' spatial ability based on mathemathical prior knowledge (MPK) and its interactions was tested by two-way ANOVA at a significance level of 5% then continued with using Post Hoc Scheffe test. The research results showed that there was significant difference in enhancement of the spatial ability between students who learnt with Cabri 3D assisted collaborative learning and students who got regular learning, there was significant difference in enhancement of the spatial ability between students who learnt with cabri 3D assisted collaborative learning and students who got regular learning in terms of MPK and there is no significant interaction between learning (Cabri-3D assisted collaborative learning and regular learning) with students' MPK (high, medium, and low) toward the enhancement of students' spatial abilities. From the above findings, it can be seen that cabri-3D assisted collaborative learning could enhance spatial ability of junior high school students .

“…Pembelajaran geometri dapat mengembangkan kemampuan pemecahan masalah dan pemecahan masalah merupakan salah satu alasan utama untuk belajar matematika (Walle, 1990). Dengan belajar geometri siswa diharapkan dapat menjadi pemecah masalah yang baik (Abdussakir, 2012). Oleh karena itu, dengan belajar geometri siswa diharapkan dapat menganalisis masalah, memecahkan masalah dan membangun suatu hubungan antara matematika dan kehidupan sehari-hari.…”

Penelitian ini bertujuan untuk mendeskripsikan strategi pemecahan masalah matematika siswa SMP ditinjau dari tingkat berpikir geometri Van Hiele yaitu visualisasi, analisis dan deduksi informal. Penelitian ini merupakan penelitian kualitatif yang menghasilkan data deskriptif. Subjek penelitian ini terdiri dari tiga siswa kelas VIII-F SMPN 1 Waru, Sidoarjo. Penelitian ini dimulai dengan menentukan subjek penelitian dengan menggunakan tes tingkat berpikir geometri Van Hiele, kemudian dilanjutkan dengan pemberian tugas pemecahan masalah dan wawancara. Pengecekan keabsahan data menggunakan triangulasi waktu. Strategi pemecahan masalah siswa akan dianalisis berdasarkan tahapan pemecahan masalah Krulik dan Rudnick, yang terdiri dari (1) membaca dan berpikir, (2) mengeksplorasi dan merencanakan, (3) memilih suatu strategi, (4) menemukan jawaban, dan (5) meninjau dan mendiskusikan. Hasil penelitian menunjukkan bahwa 1) siswa visualisasi dalam memecahkan masalah matematika menggunakan strategi membuat gambar, berpikir logis, menulis persamaan atau kalimat terbuka, dan membuat daftar yang teratur, subjek visualisasi belum memahami bahwa persegi merupakan persegipanjang. 2) Siswa analisis memecahkan masalah matematika menggunakan strategi berpikir logis, menguji dan menerka serta membuat gambar, subjek analisis belum memahami bahwa persegi merupakan persegi panjang. 3) Siswa deduksi informal dalam memecahkan masalah matematika menggunakan strategi membuat gambar, berpikir logis, menulis persamaan atau kalimat terbuka serta menerka dan menguji, subjek deduksi informal telah memahami bahwa persegi merupakan persegipanjang.

“…Sedangkan di perguruan tinggi, berdasarkan pengalaman, pengamatan dan penelitian ditemukan bahwa kemampuan mahasiswa dalam melihat ruang dimensi tiga masih rendah. Bahkan dari berbagai penelitian, masih ditemukan mahasiswa yang menganggap gambar bangun ruang sebagai bangun datar, mahasiswa masih sulit menentukan garis bersilangan dengan berpotongan, dan belum mampu menggunakan perolehan geometri SMU untuk menyelesaikan permasalahan geometri ruang (Abdussakir, 2009). Menurut Abdussakir (2009) bahwa pada dasarnya geometri mempunyai peluang yang lebih besar untuk dipahami siswa dibandingkan dengan cabang matematika lain.…”

This article discussed about theory applaying learning according Van Hiele is learning that focus on Geometry. This theory is found that to study Geometry the student have a development to think step by step certain. The steps student cognitive level consist of 1) Visualisation level is introducing level, 2) Analisys level is description level, 3) Abstraction level (deduction informal) is arraged level or relational level, 4) Deduction formal level, and 5) Rigor level is systhematys level. This implementation in the class Van Hiele determine some of learing faces 1) Information is about question answer for introducing the student, 2) Direction method is about the students to know the topic that have been learned by tools with accorate that have prepared the teacher make some observation, 3) Explication is explain a view appear about structure that have observation, 4) Free orientation is how the students faced task more than a way and task open ended and fase and 5) Integration is the students observe review and resume that have learn. Study applying theory Van Hiele more than applying on student activity, because student activity is role important on the procees of learning used study applying theory.
