The main purpose of this Master’s thesis is to contribute to an increased understanding of student teacher’s information seeking for their studies. The role of cognitive authorities and approaches to the critical evaluation of sources are taken into account as well as what student experiences of information seeking imply for their future profession. The study takes a sociocultural perspective and the empirical material is based on interviews with six student teachers at the end of their education. The interviews have been analysed with a departure point in the research questions to the following themes; seeking and finding information, critical evaluation of sources and, analysing and using information. The major findings concern the teacher students’ emphasis on the importance of the critical evaluation of sources and their scepticism towards Internet use, both for their own studies as well as for their future pupils. The student teachers expressed awareness of cognitive authorities when seeking information in formal printed sources, but they were not fully aware of the role of teachers and supervisors as cognitive authorities. Several of the informants expressed a need for teaching methods related to information seeking.
