The purpose of the study is to investigate the students' attitudes towards using interactive whiteboard in mathematics classrooms in the middle and high school. The IWB survey was used to measure students' attitudes. The research sampling consisted of 112 students in middle schools and 231 students in high schools in Balikesir in Turkey. The structural validity of scale was tested through confirmatory factor analysis. The reliability of the scales was tested through Cronbach's Alpha Coefficient. The item discrimination of the scales was calculated through the corrected item total correlation and a comparison between the top and bottom 27% groups. The results of analysis show that students have positive attitude towards the use of IWB. Also t-test method was used to test whether students' attitudes differ in terms of gender, school type and mathematics achievement.
