Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i2 Novices' fixations were significantly more dispersed than experts' across all videos. → Charlotte E. Wolff 2016
Evidence¶

Charlotte E. Wolff, Halszka Jarodzka, Niek van den Bogert, Henny P. A. Boshuizen. (2016). Teacher vision: expert and novice teachers' perception of problematic classroom management scenes. Instr Sci 44:243-265. https://doi.org/10.1007/s11251-016-9367-z
q3 · i2 · associational · r1
Eye-tracking experiment in which 67 teachers viewed four authentic lesson videos; a mixed-design repeated measures ANOVA on fixation dispersion average showed a main effect for expertise (F(1, 60) = 6.04, p = 0.017) with the printed effect size g2 = 0.10 (the article's notation for eta-squared, in the medium range). The article reports "Novices' fixations were significantly more dispersed than experts".
"Statistical analysis with a mixed-design ANOVA showed a main effect for expertise with ‘fixation dispersion average’, F(1, 60) = 6.04, p = 0.017, g2 = 0.10."
Discussion¶
Learner Variables¶
- Prior Knowledge — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Novices skipped more classroom areas than experts in all four videos, missing areas that experts continually monitored — related
- Experts revisited (monitored) more classroom areas showing student interaction, while novices revisited areas lacking classroom activity — related
- Expert teachers' classroom perception appears knowledge-driven while novices' appears image-driven, guided by salient visual features — related
- Teaching experience is associated with higher frequency of mental/perceptual and action/event words in think-aloud about classroom scenes — related
- Evidence that domain-general perceptual-cognitive skills distinguish athletes is mixed; expertise appears domain-specific — related
- Expert teachers fixate more on struggling, underestimating, and uninterested students during individual seatwork, while novices show longer fixations on strong and overestimating students — related
- Both novice and expert teachers state valid behavioral cues when inferring student profiles, but novices rely more on salient cues such as hand raising and quality of answers — related
- Expert teachers show expertise-related eye movement patterns in some classroom tasks but not others, indicating task and context specificity — related
