Özet:

Conducted in survey and descriptive research design, the purpose of this study was to define the teacher candidates’ geometric thinking levels and their attitudes towards geometry. The sampling of the study was based on 304 students in the Computer Education and Instructional Technology, Science and Technology Education, and Primary School Education departments. In the research, the “Van Hiele Geometric Thinking Test-VHGDT” and the “Geometric Attitude Scale” were used as data collection tools. Van Hiele Geometric Thinking Test (VHGDT) was developed by Usiskin (1982). As a result of the study, it was concluded that the teacher candidates were at various thinking levels. Their attitudes towards geometry were high and there was a significant but very low relationship between the “anxiety” sub-factor of the teacher candidates towards geometry and geometric thinking. In addition, the variables of gender, the type of high school they had graduated from and their academic achievement did not affect the students’ geometric thinking levels.
