In the Swedish educational system, there has been a recent push for digital technology in different school subjects. This paper investigates what regulates Swedish physical education teachers’ perceptions of digital technology in outdoor education. The results is reflected in a number of rules that govern Swedish physical education teachers’ perceptions and use of digital technology in outdoor education. Findings suggest that teachers’ views on the relevance of digital technology in outdoor education depends partly on curriculum formulations, but of significant importance are also other factors such as: the addressed knowledge area, grade level, choice of digital device, needs of students, and teachers’ ideological beliefs. These rules are discussed in relation to the construction of outdoor education as knowledge area within physical education and in relation to the ways in which Swedish physical education teachers relate to curriculum changes.
