Supporting pupils’ development regarding subject knowledge and disciplinary literacy is a complex and challenging task for teachers. Research shows that language-integrated physical education (PE) can assist children’s language development. However, it tends to reduce the time for physical activity, which is problematic since youth’s physical inactivity is a growing problem. This article examines how teachers can emphasize disciplinary literacy and stimulate pupils’ use of verbal language to enhance their learning in PE in a culturally and linguistically diverse context in Sweden. In this practice-based research study grounded in action research methodology, 20 ten-year-old pupils with culturally and linguistically diverse backgrounds participated with a teacher-researcher in 10 PE lessons in which disciplinary literacy and verbal language were intertwined with exploratory circus assignments. The theoretical framework is based on Biesta’s concept of risk. Data were collected through participant observation, video observation, interviews, and field diary. The data analysis was abductive, oscillating between the theory and the data. A thematic analysis was carried out. The results show that the exploratory circus assignments offered opportunities to emphasize disciplinary literacy and stimulate pupils’ use of verbal language. Focusing on language to ensure all pupils could partake and develop knowledge required time, which encroached on the pupils’ opportunity to be physically active. This was resolved through adding time before the PE lesson to activate the pupils’ background knowledge, anchor the language, and create pre-understanding. Further, including all pupils was challenging, and the pupils had different expectations regarding PE. The findings suggest that inviting pupils to speak involves an embedded risk in communication, but also carries dialogical potential. In collaboration with teaching colleagues, PE teachers can support and strengthen the pupils’ literacy development.
