Abstract
The important role in learning and upbringing played by teachers has been acknowledged for a long time. However, research on this question belongs with few exceptions, to the post‐war area in all the Nordic countries. During the last few decades a extensive research within a variety of studies have addressed the question. And, in accord with realistic expectations, the research conducted within this area since the middle of the 1950ties reflects a change in the interest of researchers similar to that found outside the Nordic countries, from studies of teacher behaviour to research on teacher cognition and analyses of the interactions between students and teachers in the classroom. The review also reveals a clear and significant change in the use of research methods: quantitative methods have declined while qualitative methods have expanded. It seems characteristic of research within this area that a great number of studies have been explorative in nature and that few of them have been followed up by more intensive and theoretically grounded research. It is the authors' opinion that, considering the great number of unanswered questions and the importance of solid knowledge of the questions related to teachers' qualifications and to teacher education, it seems that research within this area is still in its infancy stage.
