<p>Life in the classroom is complex with all sorts of action taking place all at once. During project work this complexity is even more visible due to intense pupil and teacher activity. The project work method and the use of ICT give the teacher more strings to play on, but it demands more of them to play in tune. In such a setting the pupils also act differently than in traditional classrooms. They need help to work together in groups, they need help to use the various tools properly, among them ICT, in the work process, and they need help to structure their work to guide them towards their goals, to mention just a few of the challenges teachers will encounters in their teaching practice. The research process has helped me to obtain a deeper understanding of the processes involved in project work using OCT as a mediating artefact. </p>
