Subclaims¶

q3 i3 During attentional gaze, intra-individual scanpath similarity was significantly greater than inter-individual similarity (M = 0.43 vs M = 0.38). → Nora A. McIntyre & Tom Foulsham 2018 q3 i3 During communicative gaze, intra-individual similarity (M = 0.40) exceeded inter-individual similarity (M = 0.37). → Nora A. McIntyre & Tom Foulsham 2018 (2)

Nora A. McIntyre & Tom Foulsham. (2018). Scanpath analysis of expertise and culture in teacher gaze in real-world classrooms. Instructional Science 46, 435-455. https://doi.org/10.1007/s11251-017-9445-x

q3 · i3 · associational · r1

Repeated-measures ANOVA on string-edit-distance similarity scores from 40 eye-tracked teachers during attentional (questioning) episodes. Within-person comparisons exceeded between-person, "intra-individual similarities were significantly greater (M = 0.43)", η²p = 0.43.

"intra-individual similarities were significantly greater (M = 0.43) than inter-individual similarities ( M = 0.38), F(1,39) = 29.14, p \ 0.001, g2p = 0.43"

q3 · i3 · associational · r2

Same repeated-measures ANOVA design applied to communicative (lecturing) episodes of the same 40 teachers. Intra-individual similarity exceeded inter-individual, "intra-individual ( M = 0.40) than in inter-individual ( M = 0.37)", η²p = 0.63.

"( M = 0.40) than in inter-individual ( M = 0.37) comparisons, F(1,36) = 61.34, p \ 0.001, g2p = 0.63"

Discussion¶

Related Claims¶

• Culture differentiates communicative but not attentional teacher scanpaths once expertise is controlled
• Teacher scanpaths are most dissimilar across combined expertise-and-culture sub-groups, significantly for attentional gaze and marginally for communicative gaze
• Teacher scanpaths are more similar within expertise levels than across expertise once culture is controlled, for both attentional and communicative gaze
• 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
• Teachers and students use gaze to express agency and communion during classroom problem-solving — related
