Description

Scanpath theory holds that a scanpath is "a 'repetitive sequence of saccades and fixations, idiosyncratic to a particular subject [person] and to a particular target pattern'" and that scanpaths reflect "the read-out of the internal representation of pictures, the so-called 'cognitive model'". The article applies this framework to real-world teaching: if expertise and culture shape teachers' cognitive models, expert and same-culture teachers should show more similar gaze sequences. Its string-edit-distance method represents gaze sequences as letter strings over coded gaze targets, preserving order information that aggregated looking-time measures discard, and the study's intra-individual similarity finding is presented as evidence that top-down cognitive models drive real-world classroom gaze.

Claims

• Teachers' gaze scanpaths are more similar within an individual than between individuals, in both attentional and communicative gaze [+M]
• Expert teachers begin gaze sequences with student fixation and return to students throughout, whereas Hong Kong experts intersperse student scans that UK experts never use [+W]
• Teacher scanpaths are more similar within expertise levels than across expertise once culture is controlled, for both attentional and communicative gaze [+W]
• Teacher scanpaths are most dissimilar across combined expertise-and-culture sub-groups, significantly for attentional gaze and marginally for communicative gaze [+W]
• Culture differentiates communicative but not attentional teacher scanpaths once expertise is controlled [+W]
