چکیده

Integration of technology, social learning, and scientific models offers pedagogical opportunities for science education. A particularly interesting area is thermal science, where pupils often struggle with abstract concepts, such as heat. In taking on this conceptual obstacle, we explore how hand-held infrared (IR) visualization technology can strengthen pupils’ understanding of thermal phenomena. Grounded in the Swedish physics curriculum and part of a broader research programme on educational uses of IR cameras, we have developed laboratory exercises around a thermal storyline, in conjunction with the teaching of a heat-flow model. We report on a narrative analysis of how a group of five fourth graders, facilitated by a researcher, predict, observe and explain (POE) how the temperatures change when they pour hot water into a ceramic coffee mug and a thin plastic cup. Four chronological episodes are described and analysed as group interaction unfolded. Results revealed that the pupils engaged cognitively and emotionally with the POE task, and in particular, held a sustained focus on making observations and offering explanations for the scenarios. A compelling finding was the group’s spontaneous generation of multiple “whatifs” in relation to thermal phenomena, such as blowing on the water surface, or submerging a pencil into the hot water. This was followed by immediate interrogation with the IR camera; a learning event we label instant inquiry. The pupils’ expressions largely reflected adoption of the heat-flow model. In conclusion, IR cameras could serve as an access point for even very young pupils to develop complex thermal concepts.

Iranian TEFL Graduates’ Conceptions of Measurement Error in Research: A Genealogical Narrative Inquiry

The aim of this study is to investigate Iranian TEFL graduates’ conception of measurement error in research. Adopting a sequential explanatory multi-method strategy (Borg, 2009), the researchers analyzed causal and temporal relations in the research narratives elicited from 30 TEFL graduates. Gee’s (1986) framework for identifying narrative discourse units (lines, stanzas, and episodes) was ado...

Ethicality of Narrative Inquiry as a Tool of Knowledge Production in Research

The sociocultural ways of conceptualizing human learning in general education have given rise to various sensitive and time-consuming tools of knowledge production for both the researcher and the researched. The gravity of the situation is more noticeable in narrative inquiry methodology, which has gathered momentum in both general education and second language teacher education (SLTE) because ...

Students framing of laboratory exercises using infrared cameras

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 1⁄4 30) partook in four IR-camera laboratory activities, designed around the predict-observe-explain approach of White and ...
