De har samma temperatur, men den här är kallare : En kvalitativ studie om mellanstadieelevers förståelse av det fysikaliska fenomenet värmeledning

Sammanfattning: The study identifies a specific problem area related to students' misconceptions about heat and heat conduction. The aims of the study are to contribute knowledge about how practical activities with thermal cameras impact the interaction and understanding of heat conduction among intermediate-grade students. The study was conducted with 23 fifth-grade students in two different schools in Sweden. To address the study's purpose, groups of three to four students were observed during a designed activity in which we participated. This activity included discussions and experiments on heat conduction using a thermal camera. The activity was recorded on video and later analysed. The results of the study, presented in three experiments, indicate that the use of thermal cameras can effectively support students' understanding of heat conduction. Students articulate the concept of heat conduction and use it in discussions. Visualizing heat with the help of thermal cameras facilitates students in connecting theoretical concepts to practical situations and enhances their ability to explain and reason about the phenomenon. The study also highlights the teacher's role in guiding students in their development. Despite some difficulties in verbalizing their conclusions, students show increased awareness of heat conduction and its connection to different materials. The study thus emphasizes the potential of using thermal cameras to support teaching and improve students' understanding of how heat spreads.
