Subclaims¶

q3 i? There was no main effect of PAL interaction type on attitudes; the hypothesis that a responsive PAL would positively affect attitudes was not supported. → Kim 2006 q3 i? The overall MANCOVA showed no significant interaction effect between competency and interaction type. → Kim 2006 (2)

Evidence¶

Kim 2006¶

Kim, Y., Baylor, A. L., & PALS Group. (2006). Pedagogical Agents as Learning Companions: The Role of Agent Competency and Type of Interaction. Educational Technology Research and Development, 54(3), 223-243. https://doi.org/10.1007/s11423-006-8805-z

q3 · i? · causal · r2

Null finding from the univariate analyses in the 2x2 experiment with 72 undergraduates; no effect size was printed for this contrast, so the finding reports non-detection rather than equivalence.

"There was no main effect of PAL interaction type on attitudes. Hypothesis 4 that the responsive PAL would have a positive impact on student attitudes toward the PAL was not supported by the results."

q3 · i3 · causal · r2

Omnibus MANCOVA with prior self-efficacy as covariate across four dependent variables; significant main effects for competency (Partial η2 = .28) and interaction type (Partial η2 = .15) but no significant interaction effect.

"The overall MANCOVA yielded a significant main effect for competency, Wilks's Lambda = .72, F (4, 61) = 5.81, p < .001, Partial η2 = .28, and a significant main effect for interaction type, Wilks 's Lambda = .85, F (4, 61) = 2.61, p < .05, Partial η2 = .15. There was no overall significant interaction effect between competency and interaction type."

Discussion¶

Related Claims¶

• A high-competency PAL elicits more positive learner attitudes toward the agent (d = 0.91) — related
• In the responsive condition, learners requested less than half of the information the PAL was designed to deliver — related
• A proactive PAL improves learners' recall of the agent's ideas more than a responsive PAL (d = 0.78) — related
• Proactive PALs yielded higher recall than responsive PALs, with the advantage differing by learner academic strength — related
• Elaboration strategy does not significantly affect students' attitudes toward the learning method — related
