PCK som ”Materialefaglighed” – videns og handlingsstrukturer i naturfagslokalet

Based on empirical data from three teachers’ practice in the field of primary science (science and technology), the article discusses the relationship between materiality and the development of Pedagogical Content Knowledge (PCK). Methodologically, narrative inquiry is used as an approach in the analysis of the multiple data from in-depth interview, classroom observation and stimulated reflection. The results show several types of connections and pathways for perceived PCK development. Both socio-material resources and collegial collaboration around experiential material practice are highlighted. The analyzes show that PCK in science and technology is not only perceived as cognitively tied to the individual, but also linked to central materials and elements of the teachers’ practice. At the same time, teachers perceive the development of PCK as being linked to the availability of particular socio-material structures, and to meaningful collaboration with colleagues who can convey, exemplify and make available the knowledge distributed in the materials. As a result of the analyzes, the concept of “Materialefaglighed” (Material- PCK) is constructed and stated as an analytical concept that contains the science teacher’s distributed and socio-materially linked knowledge, ability and doing.
