Teaching of geometry in Bulgaria
Geometry plays an important role in the school mathematics curriculum all around the world. Teaching of geometry varies a lot (Hoyls, Foxman, & Kuchemann, 2001). Many countries revise the objectives, the content, and the approaches to the geometry in school. Studies of the processes show that there are not common trends of these changes (Mammana & Villani, 1998). This paper describes the recent state of geometry teaching in Bulgaria. The main ideas and principles in the development of school geometry are presented. The preparation of future mathematics teachers to teach the subject is also considered.
