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 i? No interaction between gaze feedback and PCA was found for any collaborative-process code; H1c-1 was not supported. → Hayashi 2020
Evidence¶
Hayashi 2020¶
Hayashi, Y. (2020). Gaze awareness and metacognitive suggestions by a pedagogical conversational agent: an experimental investigation on interventions to support collaborative learning process and performance. International Journal of Computer-Supported Collaborative Learning. https://doi.org/10.1007/s11412-020-09333-3
q3 · i? · causal · r2
The 2×2 ANOVAs run for each of the coded collaboration codes reported no significant gaze × PCA interaction, and the article states "H1c-1 is not supported"; no effect size was printed for this null result.
"However, the statistical analysis results show that there were no interactions; therefore, H1c-1 is not supported."
Discussion¶
Related Claims¶
- Gaze feedback and PCA suggestions interact on proportional learning gains, with synergy favoring the visible-gaze/visible-agent condition — related
- A successful coordination/high learning-gain correlation appears only for learners receiving both visible gaze feedback and PCA suggestions — related
- Visible real-time gaze feedback improves collaborative-process coordination, especially information pooling, in dyadic knowledge integration tasks — related
- Consensus reaching and task division together predict learning gains across conditions — related
- PCA metacognitive suggestions improve consensus reaching, task division and reciprocal interaction during collaboration — related
- In a 2x2 experiment on jigsaw dyads, the implicit gaze awareness tool affected dialogue processes much more than the explicit pedagogical conversational agent, which compensated when gaze awareness was absent — reports the opposite
