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 i3 Both groups improved significantly in declarative knowledge over time (main effect of Time, η2 =.27), with no significant Group × Time interaction, indicating both formats equally supported declarative knowledge. → Polly K. Lai 2026

q3 · i3 · causal · r2
Repeated-measures ANOVA in the same 27-participant randomized experiment found a significant main effect of Time on declarative knowledge, "F(1, 25) = 9.24, p =.005, η2 =.27"; the article reports no Group × Time interaction for this outcome.
"For declarative knowledge, there was a significant main effect of Time, F(1, 25) = 9.24, p =.005, η2 =.27, indicating overall learning gains across groups (see Fig. 3)."
Discussion¶
Related Claims¶
- Undergraduate students learning nanoscience with agent-based models show greater gains in explanatory knowledge than students learning with visualization videos — 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
- Both conditions improved in overall idea units, evidence-based units and functional units, with no significant condition-by-time differences
- Instructional videos and AI chatbots show complementary rather than redundant functions for science learning — related
- Students in a collaborative, project-based engineering design course gained declarative knowledge but not procedural or principled knowledge or personal interest — related
- Representational format produced no significant differences in conceptual or situational knowledge — related
