Gender Differences in Textbooks and Teachers’ Gender Perceptions This research has been made to determine sex perception of teachers who are working in primary schools and examine the text books which are thought in primary schools from the point of view of gender. With this purpose, a questionarre was given to teachers for data collection. At the same time, textbook pictures and passages were evaluated to determine the number of boys and girls, the place they had been, the people they had been on contact and adviced jobs for different sexes. As a result of the research in the social structure at the school, the teachers and the passages and pictures in textbooks were determined to have gender bias. Comittees who struggle against sex perception should choose textbooks and the teachers should be conscious about this subject. The struggle against sex perception should include all the society.
