Abstract

Penelitian ini bertujuan mendeskripsikan tingkat berpikir geometri dan proses berpikir geometri siswa sekolah menengah pertama menurut tingkat berpikir van Hiele pada topik segiempat. Penelitian ini menggunakan pendekatan kualitatif dengan metode studi kasus dengan mengujikan soal Van Hiele Geometry Test (VHGT) yang diadaptasi dari CDASSG Usiskin dan melakukan wawancara mengenai proses berpikir berupa mengidentifikasi, mendefinisikan, dan mengklasifikasikan yang diadaptasi dari pedoman wawancara Burger dan Shaughnessy (1986). Subjek penelitian ini sebanyak 297 orang siswa kelas VII dan VIII dari dua sekolah yang berada di kecamatan Lembang. Hasil penelitian mengunjukkan bahwa siswa kelas VII dan VIII tersebar pada level pravisualisasi dan level berpikir van Hiele yaitu level 0 (visualisasi) dan level 1 (analisis) . Hasil tes VGHT menunjukkan bahwa siswa level pravisualisasi, level 0, dan level 1 sebagai berikut: 1) sudah mampu mengenali jenis-jenis segiempat, namun masih terpengaruh prototipe, 2) siswa belum mampu mengklasifikasikan segiempat, dan 3) siswa level 1 belum mampu memahami sifat-sifat sudut dan diagonal pada belah ketupat dan persamaan sifat-sifat antara layang-layang dan belah ketupat. Secara keseluruhan deskripsi proses berpikir geometri setiap levelnya berupa aspek mengidentifikasi, mendefinisikan, dan mengklasifikasikan sesuai dengan karakteristik berpikir van Hiele secara umum.; This study aims to describe the level of geometric thinking and geometric thinking processes of junior high school students according to van Hiele's level of thinking on the topic of quadrilaterals. This research uses a qualitative approach with a case study method by testing the Van Hiele Geometry Test (VHGT) which was adapted from the CDASSG Usiskin and conducting interviews about the thinking process in the form of identifying, defining, and classifying which was adapted from the interview guide of Burger and Shaughnessy (1986). The subjects of this study were 297 grade VII and VIII students from two schools located in Lembang sub-district. The results of the study show that the students of grades VII and VIII are spread out at the previsualization level and van Hiele's thinking level, namely level 0 (visualization) and level 1 (analysis) . The results of the VGHT test showed that the students at the previsualization level, level 0, and level 1 were as follows: 1) have been able to recognize the types of quadrilaterals, but are still affected by prototypes, 2) students have not been able to classify quadrilaterals, and 3) level 1 students have not been able to understand the properties of angles and diagonals on a rhombus and the similarity of properties between kites and rhombus. Overall, the description of the geometric thinking process at each level is in the form of identifying, defining aspects, and classify in accordance with the characteristics of van Hiele's thinking in general.
