Subclaims¶

q3 i? For the visible-gaze/visible-agent condition the process–performance regression was significant (R2 = 0.322), supporting H2-2. → Hayashi 2020 q3 i? For the no-gaze/no-agent condition the regression was not significant (R2 = 0.085). → Hayashi 2020 (2)

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 · r?

A separate multiple regression was run per condition; only the visible-gaze/visible-agent condition showed a significant process–performance relation, "R2 was 0.322", consistent with H2-2.

"For the visible-gaze/visible-agent condition, R2 was 0.322, and the ANOVA F-value was 4.035, indicating statistical significance ( p = 0.037)."

q3 · i? · causal · r2

In the no-gaze/no-agent condition the regression did not reach significance; the article treated this as a null result and no effect size was printed.

"For the no-gaze/no-agent condition, R 2 was 0.085, and the ANOVA F-value was 0.786, indicating no statistical significance ( p =0 . 4 7 2 ) ."
