Subclaims¶

q3 i3 The ABM group improved significantly in explanatory nanoscience knowledge from pre- to post-test whereas the video group showed minimal change, with a significant Group × Time interaction (η2 =.15). → Polly K. Lai 2026

q3 · i3 · causal · r2

Randomized experiment with 27 undergraduates assigned to an ABM (n = 14) or video (n = 13) condition; 2 × 2 repeated-measures ANOVA on explanatory knowledge showed a significant Group × Time interaction, F(1, 25) = 4.39, p =.046, η2 =.15, and the follow-up contrast found "the ABM group demonstrated significant improvement" with η2 =.20.

"Follow-up contrasts indicated that the ABM group demonstrated significant improvement from pre-test (M = 0.75, SD = 0.70) to post-test (M = 1.21, SD = 0.70), F(1, 25) = 6.12, p =.021, η2 =.20, whereas the video group showed minimal change (pre-test M = 0.50, SD = 0.46; post-test M = 0.54, SD = 0.56)."

Discussion¶

Related Claims¶

• Both agent-based model and visualization video conditions produce comparable gains in declarative nanoscience knowledge, with no Group × Time interaction — related
• The agent-based model group outperforms the visualization video group on transfer problems applying size-dependent properties to novel contexts — related
• ABM students engage more frequently in embodied reasoning strategies—first-to-third-person perspective shifts, causal inference making, and gestures—than video students, who rely more on third-person perspectives and information retrieval — related
• First-to-third-person perspective shifting, causal inference making, and gesture use correlate positively with explanatory and transfer scores, while information retrieval and handwriting correlate negatively — related
