In this presentation I will discuss teachers' pedagogical thinking concerning the use of information and communication technologies in university teaching. I am interested in how university teachers define teaching and how information and communication technologies are associated, if at all, with that definition. In other words, is intensive use of ICTs in teaching such an constitutive element that it has some impact on how teachers understand teaching? This far, I have interviewed 32 teachers at the University of Helsinki University. University teachers' conceptions of teaching have been investigated, but I have not found any literature in which these conceptions have been investigated in the context of the use of information and communication technologies. In present times, when technologies are intensively used in education the link between the conception of teaching, on the one hand, and information and communication technologies, on the other hand, is worth exploring. The categories I have found so far are: Empowerment of one's pedagogical view. Teachers suggested that by using information and communication technologies, they are better able to teach according to their own pedagogical views than without it. Authority of knowledge. The context of information and communication technologies has an impact on the relationships between a teacher, the substance (knowledge) and a student. Authority over knowledge is shifting from teacher to net-based resources, and from static resources (like books) to flexible resources (like the web). Technology as substance and a tool. This category concerns the technology itself. It may be the content of teaching. On the other hand, technology is treated as a tool, an agent in pedagogical activities. Some specific perspectives. Some teachers presented very sophisticated views of the relationship between the definition of teaching and information and communication technologies, which was based on their own theoretical elaboration.
