Information and Communication Technology (ICT) can be integrated in the classroom processes in different ways. This study reveals ICT, as a mediating artefact in project work can contribute to the learning processes in the classroom. When ICT is used as an artefact to make a film, planning and decision making becomes natural and necessary processes in the pupil groups. The case study takes both the pupils' and the teachers' perspective and focuses on the learning environment and what it means for the learning processes. To understand and get more insight in the actions taking place in the classroom, the processes are analyzed from the theoretical point of view provided by social constructivist theories. The rationale for the article is to describe and thus show how the classroom structure is shaped by both the project work method and the ways the teachers organize the work and guide the pupils throughout the process in which ICT is a central mediating artefact.
