The abstraction of junior high school student in learning geometry

Abstract

This paper is prepared to describe the abstraction of junior high school students in studying geometry, in this case studying cubes and constructing cube nets. Abstracts were obtained through interviews that aim to get a picture of the abstraction that occurs in students in learning cube activities and constructing cube nets which are part of learning geometry. The data is presented in the form of an interview transcript which explains how students learn the cube pattern and constructing cube nets by remembering previous learning activities and imagining the shape of the cube pattern and cube nets in their mind which is then visualized. Based on these data, it can be concluded that the abstraction of junior high school students in geometry learning activities is an abstraction which is an epistemic action which includes recognition, build-whit and constructions that are interrelated with one another.
