q2 i? The means for all computer vision clusters increased post-PD, and cluster 1 (the highest-mean cluster) grew to contain more constructs after PD. → Kurz 2026

q2 · i? · causal · r1

Descriptive statistics from the computer vision repertory grids (Tables 1 and 2) show that every cluster's mean rose post-PD and that cluster 1, the most descriptive cluster, expanded from four to twelve constructs. The authors report "The means for all clusters increased post-PD," indicating teachers rated computer vision constructs as more descriptive after the intervention.

"Cluster 1 had the highest mean for both pre-PD and post-PD, as well as the lowest standard deviation out of all the clusters both pre-PD and post-PD. A high mean indicates that the participants thought of the cluster as very descriptive of computer vision. The means for all clusters increased post-PD."

Discussion¶

Related Claims¶

• Teachers' construct for computer vision 'sensing the surroundings' was initially viewed as not descriptive of computer vision but became more descriptive after PD — related
• After PD, teachers rated computer vision as more similar to human vision, with computer vision cluster 1 matching human vision cluster 1 on seven constructs post-PD versus one pre-PD — related
• Teachers' perceptions of human vision remained largely stable following computer vision PD, with only one construct (6%, n = 1) shifting clusters — related
• Individual computer vision constructs showed notable mean increases and cluster shifts, including sensing the surroundings (26% increase, cluster 4 to 2) and able to detect objects (18% increase, cluster 3 to 1) — a narrower finding that bears on this claim
• After a two-to-three-week computer vision professional development program, 13 of 18 (72%) of middle school teachers' computer vision constructs shifted clusters, which the authors read as restructured perceptions (pre/post, no comparison group) — a narrower finding that bears on this claim
