q3 i? Significant negative quadratic interaction terms for mental pathway span with both dynamic and static design indicate nonlinear, inverted-U relations, significantly more accentuated for the dynamic design. → Tim Kühl 2022

q3 · i? · causal · r2

Multi-level model analysis of the experiment with N = 77 university students performing a mental integration task under static and dynamic visual designs (within-subjects), with mental pathway span as continuous predictor. The quadratic terms were 'significantly different (z = −2.60, p = .009)', showing the inverted-U progression was stronger for the dynamic design.

"The significant quadratic terms for the interaction of mental pathway span with visual design, dynamic and static, b [(mental pathway span × dumOpt)2] = −.08, p < .001 and b [(mental pathway span × dumSub)2] = −.04, p = .036 (Table 2), indicate non-linear relations with negative quadratic trends for both presentation forms."

Discussion¶

Learner Variables¶

• Spatial Ability — moderator: an instructional effect differs with it
• Working Memory — moderator: an instructional effect differs with it

• The mental integration task showed no general advantage of the dynamic over the static visual design in overall accuracy — related
• Reanalysis of pooled data from four multimedia learning experiments found quadratic interactions, with the largest design difference at medium ability — related
