Research Update #13: Online Agents have Small but Positive Learning Effects: Meta-analysis
LDA friend and Executive Advisory Board Member, Ruth Colvin Clark provides a twice-monthly research update. These updates are single-page infographic/ summaries you can open, read, download, and file for later review and reference.
In this thirteenth review from Ruth, she shares a meta-analysis that included 29 reports published between 2012-2019. These reports found that online pedagogical agents improve learning but with only a small impact (effect size 0.20). The meta-analysis evaluated different features of online agents such as appearance, motion, and voice to identify how to design most effective agents. Simpler renditions of agents were found to be more effective; other features yielded no significant differences.
