PRE-SERVICE CLASSROOM TEACHERS’ KNOWLEDGE ON POINT, LINE, PLANE AND SPACE AND THEIR REPRESENTATION

The aim of this study was to determine the multiple representations that were being used by teacher candidates for the concepts of point, line, surface and space and was to interpret these representations in terms of the content knowledge and the pedagogical knowledge. The participants of the study were consisted of 122 first-year college students from the program of classroom teacher education. Data were collected through nine open-ended questions after processing the Basic Mathematics II course and was analyzed by means of descriptive techniques that allowed 9 different categories. Candidates interpreted the concepts on the plane as one-dimensional and two-dimensional. Accordingly, the foundation of classroom teachers’ geometry knowledge of point, line, surface and space needs to be expanded to threedimensional aspects. In addition, comments were provided for expanding hours and improving ingredients of Basic Mathematics II course in order to support teacher candidates’ knowledge of geometry.
