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? A meta-analysis of 43 studies with more than three thousand subjects found statistically significant learning benefits for learning environments featuring pedagogical agents over those without agents. → W. Lewis Johnson & James C. Lester 2015

q3 · i? · review · r2
Narrative summary of the Schroeder et al. (2013) meta-analysis of 43 studies involving more than three thousand subjects, as reported in this article's retrospective section. The review found agents do enhance learning, described as statistically significant, with no printed effect size.
"the meta-analysis discovered statistically significant results among the studies. In particular, the meta-analysis found that agents do enhance learning in comparison with learning environments that do not feature agents"

- Pedagogical agents have a small, statistically significant positive effect on learners' broadly defined 'motivation' (g = 0.20) — related
- Pedagogical agents significantly improve learners' self-efficacy expectations (g = 0.29), with effects moderated by grade level, facial expressions, and reliability reporting — related
- Pedagogical agents significantly improve learners' interest (g = 0.30), with the effect depending on the type of control condition — related
- Pedagogical agents do not significantly affect learners' engagement (g = -0.02, non-significant) — related
