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.
q4 i1 Across 32 effect sizes (N = 2104), learning with multimedia pedagogical agents was more effective than learning without these agents, with a small pooled effect of g+ = 0.20. → Castro-Alonso 2021

q4 · i1 · quant-synthesis · r?
Meta-analysis pooling 32 effect sizes from studies of multimedia pedagogical agents, total N = 2104. The printed pooled effect size is g+ = 0.20, a small effect favoring learning with agents over learning without them.
"Our meta-analysis of 32 effect sizes ( N = 2104) revealed a small overall effect ( g + = 0.20), showing that learning with multimedia pedagogical agents was more effective than learning without these agents."
Discussion¶
Related Claims¶
- 2D pedagogical agents tended to be more effective than 3D agents (g+ = 0.38 vs. g+ = 0.11), as predicted by the redundancy effect and the coherence principle — related
- Multimedia design principles improve learning by g = 0.38 on average across the 11 largest reviews, an effect the authors call moderate, with large differences between principles — a broader claim this one bears on
- Most agent characteristics, including nonverbal communication, motion, and voice, did not moderate the instructional effectiveness of pedagogical agents — related
- Pedagogical agents have a small, statistically significant positive effect on learners' broadly defined 'motivation' (g = 0.20) — related
- Pedagogical agents significantly improve learners' interest (g = 0.30), with the effect depending on the type of control condition — 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 show a small-to-moderate but non-significant effect on learners' utility beliefs (g = 0.34, p = 0.05) — related
