The concept of number emerges from the interaction of psychological, behavioral, and material elements of numerical cognition, collapsing the distinction between "abstract" and "concrete." This dual nature is evident in the Inca numerical system, where tools like the yupana integrate abstract numerical concepts with concrete…

Teachers' focus on their students' learning is considered central in high-quality, studentcentred university teaching. This frontline eye-movement research asks whether teachers' focus can be observed at the intersection of the visual and conceptual levels. It introduces a novel way to study teachers' visual attention combined with verbal…

This study connects to an ongoing discussion about the limits and affordances of simulators as realistic and relevant contexts for professional learning, in this case in the development of visual expertise. Earlier studies of simulator-based maritime pilot training conclude that there are risks associated with so-called negative skills transfer…

Teacher professional vision as a concept is gaining importance in research on teaching, and recently models for studying teacher professional vision and student self-regulated learning (SRL) have been proposed. There are interview and video intervention studies investigating teacher professional vision for SRL, but no real-life classroom research…

This study explored early childhood education and care (ECEC) teachers' visual gaze and related reflections on pedagogical actions during pedagogical activities in groups of children under three years of age in Finland. The data were collected from play and teacher-guided activities using mobile eye-tracking glasses, the retrospective thinking…

In this research, we aimed to investigate the visual-cognitive behaviours of a sample of 106 children in Year 3 (8.8 ± 0.3 years) while completing a mathematics bar-graph task. Eye movements were recorded while children completed the task and the patterns of eye movements were explored using machine learning approaches. Two different techniques of…

This study looks at the practice of thoracic radiology and follows a group of radiologists and radiophysicists in their efforts to find, discuss, and formulate issues or troubles ensuing the implementation of a new radiographic imaging technology. Based in the theoretical tradition of ethnomethodology it examines the local endogenous practices…

We argue that there is an increasing reliance on analytic strategies compared to visuospatial strategies, which is related to geometry expertise and not on individual differences in cognitive style. A Visual/Analytic Strategy Test (VAST) was developed to investigate the use of visuo-spatial and analytic strategies in geometry in 30 mathematics…
