Background As part of a participatory action-research project, students at the vocational upper-secondary Natural Resource Use programme in Sweden were introduced to infrared cameras in their courses. Material and methods Students were video recorded as they used infrared cameras in the investigation of pigs’ physiology and health in the school’s pig house and explained generated infrared images in whole-class dialogue, together with involved teachers and researcher. Results Students found that a pig’s injured leg has high temperature, but also, more surprisingly, udder abcesses with lower temperature than the surrounding healthy udder tissue. Students and teachers expressed excitement in explaining the results. Conclusions From the perspective of seeing vocational education as a kind of cognitive apprenticeship, students’ investigations and dialogue with the teachers and researcher are characterised as an example of authentic activity in a community of learners, where expertise was distributed across all participants.
