The pupil’s previous knowledge of migration as a starting point for the educational practice Blanck Sara At Karlstad University the project” To develop teaching on social issues: content selection and transformation in social studies education in upper elementary school, year 4-6.” is in progress. The second part of my doctoral studies is in this project. The aim is to develop knowledge about societal relevant integrative educational practices around thematic issues, with a linkage between pupils’ experiences and specialized knowledge. The focus in this presentation is on pupils’ previous knowledge of migration. Migration is one example of an urgent social issue who might have potential as a teaching theme in upper elementary school, year 4-6. It could also be address as an epoch-typical key problem according to Wolfgang Klafki´s ideas about central problems in the world that pupils need to get knowledge about and develop a will of solving (Klafki 2001). This study explores how pupils’ previous knowledge, their preconceptions and experiences of migration, can be used as a springboard making it possible for the pupils to connect to significant specialized knowledge about migration. Ingrid Carlgren’s concept of educational practice with a) knowledge practice, b) learning practice and c) didactic practice in relation to the French anthropological didactic is used as a conceptual frame to examine how content about migration reconstructs in the classroom practice (Bosch and Gascón 2014; Carlgren 2015; Chevallard 2007). Methods are observations of classroom practice, focus group interviews with pupils’ and teachers’ reflections in a research circle. The empirical ground for the discussion is a classroom-project where pupils´ previous knowledge of intern and/or extern migration isin focus. Connection can here be made to Jim Cummins and the idea of identity texts. According to Cummins working with identity texts is an effective teaching strategy especially for newly arrived pupils or pupils from marginalized groups (Cummins and Wadensjö 2017).
