Geometry is a key area of math. Reviewing the curriculum of primary and secondary school indicates that geometry is one of the major academic subjects, and it is consider one of the most difficult areas of mathematics to pupils. Quite a few studies conducted in recent decades reported the difficulties encountered by pupils that learning geometry. One of the main reasons for these difficulties is the gap between the level of teaching and learning abilities to the level of pupils understanding. The pupils are low-leveled geometric thinking, while the teachers are trying to provide them their high-leveled knowledge. Students that received in the mathematics department at academic college specialize elementary and junior high School curriculums are committed to studying various courses in geometry. Our experience at college of education, meet us with students that have difficulty at learning geometry. In order to make teaching more effective and efficient, we conducted a study that examining the level of geometric thinking of the students who want to be math teachers and come to learn in college of education. To this end, a questionnaire was comprised of 15 questions that examine the first three levels of geometric thinking by Van Hiele theory. The questionnaire was given to students who specialize in mathematics program primary and secondary school (N=84). The conclusion obtained from the study is that a significant proportion of the students received in the mathematics department at academic college control only at the lowest level. In order to qualify students to the third level, at least, we need to teach them geometric during the first semester of learning.
