The present study aimed at examining high school teachers' attitudes towards ICT use in education. With this regard, we examined whether the teachers' attitudes significantly differ according to their gender, age, teaching experience, ICT experience, ICT skills and ICT training. The participants consisted of 353 teachers working in different high schools in Ankara in the academic year 2016-2017. Research results illustrated that teachers have a high level of positive attitude towards ICT use in their classes, yet there is no significant difference between teachers' ICT willingness by their gender, age, teaching experience, ICT experience, ICT skills and ICT training. However, they have significantly different negative attitude (ICT anxiety) towards ICT use in education by their ICT experience, ICT skills and ICT training.
