Özet

The aim of this study is to investigate and discuss this knowledge restricting it to the angle concept that is multifaceted and complicated concept in geometry. The data of this research was conducted by an examination which aims to determine the teachers' (15 teachers, expert/novice) will to be accepted to a foundation school at the semester of 2007-2008 in Turkey. One of the questions in the exam was pertaining to "angle" concept. With the findings, it was noticed that the teachers defined angle such as the union of two rays, a region; and measurement of angle such as arc measurement, positive directional degree. Besides, in view of the representations the teachers used, it's concluded that the teachers don't have sufficient knowledge about "angle" concept and the measure of an angle. (c) 2009 Elsevier Ltd.
