Anxiety: How Was the Process of the Undergraduate Students Who Were in Visualization Level in Constructing the Definition?

Abstract

Definition is important mathematical construction which had been recorded as a challenging topic for teacher and students. This research showed the illustration of anxiety that happened to undergraduate students of Mathematics education who were in visualization level of thinking in constructing quadrilateral definition and definition form that had been successfully recorded. The analysis was done to determine the anxiety’s indicator that appeared and indicators of quadrilateral’s definition. Triangulation method was done to compare subjects’ worksheet, observation, and interview. The results showed that anxiety appeared when subjects started to construct the definition of quadrilateral so that the definition that had been defined was not efficient
