Hot Vision: Affordances of Infrared Cameras in Investigating Thermal Phenomena

Going through a phase: Infrared cameras in a teaching sequence on evaporation and condensation

“…In this last phenomenon, IR cameras become an indispensable measurement and visualization tool, 4 which provides pedagogical affordance in the study of thermal phenomena. 6 In conclusion, through participation in a teaching sequence with the help of IR cameras, students were able to coordinate resources from their embodied experience and previous teaching to deliver an explanatory model for evaporation. Reliance on the second law of 21 thermodynamics acted as a barrier for considering the role of potential energy in phase transitions, and thereby explaining condensation.…”

“…2 This can be considered a pedagogical affordance of the IR cameras. 5,6 However, research has yet to explore the implications of integrating the IR cameras systematically in teaching sequences. In this study, we have developed and implemented a teaching sequence on phase transitions for primary (elementary) school pre-service teacher students.…”

Invisibility Cloaks and Hot Reactions: Applying Infrared Thermography in the Chemistry Education Laboratory

“…A recent study published by Samuelsson et al discussed a related example, the deliquescence of sodium hydroxide pellets exposed to air, and reported specific affordances associated with the use of IR imaging that positively impacted students' abilities to understand and explain the phenomenon they were observing. 35 Concepts underlying enthalpy changes for these and related processes can be difficult for students to grasp. The use of IR thermography to augment sensory perception and direct attention has potential to strengthen understanding based on how students learn the topic and measures of their learning thereof.…”

Increasing Access to Science and Engineering—the Role of Multimodality

“…They make use of infrared cameras in the science classroom in order to demonstrate the pedagogical and disciplinary affordances of technology for science learning in disadvantaged contexts. Infrared cameras are also deployed in this way in the special issue by Samuelsson et al (2019) albeit with laboratory instructors and undergraduate university students of chemistry in Sweden. Both Dolo et al and Samuelsson et al not only show how technology offers affordances for science learning in different cultural settings, they also show that technology constrains action and talk on the part of learners, fixing these in particular ways.…”
