Widespread use of internet reveals the idea that it can also be more widely used for educational purposes. In this respect, teachers have a very important function in education and the determination of teachers' attitude towards internet using is also important. In the literature although it is possible to see many studies on pre-service teachers' attitude towards internet use, studies identifying the attitude regarding in-service teachers' internet using are not very common. In our study, which aims to determine the attitude of in-service teachers according to various variables, the Internet Usage Attitude Scale developed by Tav anc l and Keser (2002) was used. The participant teachers' attitudes towards internet using was analyzed and interpreted according to the variables of gender and duration of their weekly internet using. It was seen that a vast majority of the teachers have personal computers, connect to internet at home and have positive attitude concerning internet use. In addition to this it was concluded that female teachers have more positive attitude than male teachers regarding internet use in social interaction and communication.
