In this study we have examined pre - and in-service teachers' conceptions about good teachership. Eighteen 2nd year teacher students participated in the study in the spring 2008; eighteen class teachers participated in February 2009. In order to find in-service teachers' and pre-service teachers' conceptions an open-ended questionnaire was used. The questionnaire was theory-based and considered the following four topics: professional knowledge, interaction, values and ethics, and motivation. The research approach was phenomenographical. Four teacher type categories emerged: a) student centred, b) profession and teaching oriented, c) rather societally reserved, and d) society orientated, humanistic approaches to teachership. Differences between pre- and in-service teachers were seen especially as grounded in amount of teaching experience and ways of practice. Contrary to in-service teachers pre-service teachers pronounced theoretical aspects brought from their teacher education programs. They emphasized a student centred practice and stressed work endurance, renewal and development. In-service teachers' experience showed in their conceptions of students as being a source of strength. © Common Ground, Sivbritt Dumbrajs, Tuula Keinonen, Anssi Kinnaslampi, Heini Kinnaslampi.
