This paper deals with the process of expanding the virtual secondary education school network, aiming to provide daily basis, online teaching. The context of this research is the ESR funded Eastern Finland Educational Network Project, which is a network of 36 high schools providing courses via web-based learning environments. The project is a shared activity between teachers and researchers. The aim of the present study is to investigate teachers' technological pedagogical content knowledge by finding out what kind of pedagogical solutions the teachers use while designing and carrying out online teaching. In this study thirteen online courses were analysed and based on the analysis, four different course design patterns were found. The most general approach in course designs seems to be teacher centred, focusing on well guided individual learning processes. There seems to be need for development of teacher technological pedagogical content knowledge, to support approaches of more collaborative course designs.
The use of Information and Communication Technology (ICT) in education is one important competence that student teacher should develop in their academic studies. To be capable of using ICT in education, students should study both pedagogical and technical issues. In order to affect student teachers' willingness to use ICT in education, more attention should be paid to their learning experiences. In this research, student teachers' attitudes toward the use of ICT in education were studied before and after the web-based course. Based on students' learning experiences, attitudes and evaluations of the web-based learning environment, dimensions of a successful web-based learning environment were examined. According to the results, ``motivation and accuracy'', ``learner-interface interaction'' and ``learner control and self-directed learning''are the dimensions of a learning environment that encourages student teachers' to use ICT in education. A well designed learning environment also gave a realistic overview and knowledge of the possibilities and limitations of the use of ICT in education.
