Abstract [en]

Inquiry-based approaches to science education are central to recent South African primary and secondary school curricula, but have been found challenging to adopt in disadvantaged township contexts. It is therefore important to find ways of introducing inquiry-based approaches, where pupils are encouraged to investigate phenomena they are interested in and to engage in true dialogue, as opposed to teacher-led triadic dialogue. We typically experience thermal phenomena through the sense of touch, but infrared (IR) cameras provide an additional opportunity to experience heat-related phenomena through the visual sense. Previously, in a Swedish context, we have found that hand-held IR cameras allow for strong pedagogical affordances and inspire pupils to engage in inquiry in the area of thermal science. In the present case study, grade 7 and 8 pupils (13–14 years old) in two South African township schools were introduced to IR cameras during predict-observe-explain (POE) exercises on heat conduction. The results revealed that if pupils had a sufficient conceptual understanding of heat conduction beforehand, they were capable of engaging in true dialogue in relation to the exercises and interpreting the thermal camera visual imagery. However, if pupils did not show such understanding, it was tempting for them and the facilitator to resort to triadic dialogue.
