Studies of level visual thinking in geometry

Abstract

Learning mathematics is how students get information that is built capable of solving a problem. One way of thinking someone is by visual thinking. Visual thinking has an important role in the success of mathematics learning, especially in solving mathematical problems that require high-level reasoning, one of them in solving the problems of abstract geometry. Although to help students develop their ability to think visually or visualize, first the teacher must pay attention to the level of visual thinking of students. This paper aims to determine the level of visual thinking in geometry. Based on the results of the literature review the authors built three levels of visual thinking in geometry, level 0: Non-visual (NV), level 1: local visual (LV) and level 2: Global Visual (GV).
