This research is focused on secondary school chemistry teachers' (N=276) and chemistry pre-service teachers' (N=159) attitudes towards the use of information and communication technology (ICT) in education. A questionnaire constructed upon Rogers' theory of diffusion of innovation was used. Based on the answers, the respondents were grouped according to their innovativeness -- into types of innovation adopters. Analysis of the participants' responses to the statements in the questionnaire suggests that neither gender nor their teaching experience influence their innovativeness. The respondents mostly tend to hold a pragmatic view, accept the role of ICT in education. However, they need proof to decide whether to adopt it in their teaching practice. As the respondents could leave their contact information, it is possible to further focus on particular groups of innovation adopters, to observe their lessons, analyse their approach and mainly influence and support those groups, which maintain a "role model" position and trigger diffusion of innovations.
