The objective of this study is to design a temperature measurement system based on a non-contact method using a sensor camera from a webcam. The material being measured is nickel wire given an electrical current of 4.5 A-6.5 A with an interval of 0.5 A. The temperature measurement is based upon the measurement of the average pixel value…

Thermal science is a perennial obstacle for learners. Infrared camera technology provides an opportunity for pupils to confront challenging thermal ideas. From an embodied cognition perspective, sensory experiences form metaphoric relations that underpin conceptualisation and reasoning about abstract scientific phenomena. This study investigated…

Lab activities typically involve phenomena that are invisible to the naked eye. For example, in thermodynamics transfer of heat and temperature changes are perceived by the sense of touch or indirectly observed by the use of thermometers. New tools can be introduced to increase the opportunities for talking science. In this paper, we explore…

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…

This study focuses on investigating how students make use of their bodily experiences in combination with infrared (IR) cameras, as a way to make meaning in learning about heat, temperature, and friction. A class of 20 primary students (age 7-8 years), divided into three groups, took part in three IR camera laboratory experiments. The qualitative…

In science education research, there is a growing body of studies focusing on the role of multiple representations in pupils' learning. This study is based on a social semiotic perspective and in the analysis, there is a special focus on how the content is conveyed and how relations are created through interaction between teachers/pupils and the…

Background: University physics students were engaged in open-ended thermodynamics laboratory activities with a focus on understanding a chosen phenomenon or the principle of laboratory apparatus, such as thermal radiation and a heat pump. Students had access to handheld infrared (IR) cameras for their investigations. Purpose: The purpose of the…

Thermal science is challenging for students due to its largely imperceptible nature. Handheld infrared cameras offer a pedagogical opportunity for students to see otherwise invisible thermal phenomena. In the present study, a class of upper secondary technology students (N = 30) partook in four IR-camera laboratory activities, designed around the…

Integration of technology, social learning and scientific models offers pedagogical opportunities for science education. A particularly interesting area is thermal science, where students often struggle with abstract concepts, such as heat. In taking on this conceptual obstacle, we explore how hand-held infrared (IR) visualization technology can…

Thermal cameras offer real-time visual access to otherwise invisible thermal phenomena, which are conceptually demanding for learners during traditional teaching. We present three studies of students' conduction of laboratory activities that employ thermal cameras to teach challenging thermal concepts in grades 4, 7 and 10-12. Visualization of…

Research has demonstrated that many students and some teachers do not consistently apply the conservation of energy principle when analyzing mechanical scenarios. In observing elementary and secondary teachers engaged in learning activities that require tracking and conserving energy, we find that challenges to energy conservation often arise in…

What effects do different setups of museum exhibits have on visitors' conversations and interactions? The study reported here is an investigation of the role that labels and associated materials play in visitors' conversations and interactions at a heat camera exhibit. After we introduced a label to help visitors explore the insulating properties…
