q2 · i? · review · r2

The editorial reports, citing Saba et al. (2025), a comparison of PS-I and I-PS for understanding complex variable interactions using a virus transmission simulation. PS-I "demonstrated better transfer of MVC strategy and reasoning to a new context" though groups performed similarly by the end. No effect size is printed.

"While I-PS showed immediate gains in applying multivariable causality (MVC), both groups performed similarly by the end of the intervention. However, PS-I demonstrated better transfer of MVC strategy and reasoning to a new context."

Discussion¶

Related Claims¶

• Exploration-first students show more advanced MVC reasoning on the transfer task than Instruction-first students — related
• Exploration-first students transfer MVC-strategy Efficiency better, with condition-by-Task-2 interactions for Efficiency and Quality — a narrower finding that bears on this claim
• PS-I research demonstrates beneficial effects on conceptual knowledge and knowledge transfer relative to I-PS — a broader claim this one bears on
• No significant condition differences remain at posttest: both approaches converge on MVC strategy and reasoning after both phases — related
• Instruction before exploration yields immediate MVC-strategy advantages in the first exploration task, driven by shorter exploration time — related
• In Experiment 1, I-PS students solved the initial problem better but PS-I students learned more from the subsequent instructional video — related
