Identification the preliminary concept of geometry through Prambanan temple artifacts

Abstract

Abstract Student preliminary concepts are useful for knowing how much knowledge he already has. One activity that can be used to find out preliminary concepts is to ask students to describe an object. Observation skills are needed by the student to construct mathematical knowledge. This research was conducted at Prambanan Temple. The purpose of this study was to determine the preliminary concept of geometry for junior high school students. Students are invited directly to the location, then asked to describe mathematical characteristics. The method used in this paper is qualitative reseacrh in which the data analysis uses descriptive qualitative. The data collection is in the form of tests and interviews of 3 students of Junior High School Penelitian ini bertempat di Candi Prambanan dengan rentang waktu 2 minggu. The result of the research is that the students can describe the character of geometry in Prambanan Temple such as rectangle, square, triangle, circle, cube, cuboid, and cylinder which becomes student’s preliminary concepts of geometry.
