q2 i? Across research syntheses, instructional approaches including inquiry learning show more positive effects on conceptual knowledge than direct instruction. → de Jong 2023 q2 i? Assisted inquiry is more effective than explicit instruction, while unassisted discovery is less effective than explicit instruction. → de Jong 2023 (2)

q2 · i? · review · r2

The review reports that the Minner et al. (2010) synthesis of 138 studies found "51% of the studies indicated a positive effect of inquiry-based instruction" on conceptual knowledge, with only 2% showing negative impact; 42 studies involved direct controlled comparisons.

"Minner, Levy, and Century (2010) analyzed the findings of 138 studies that included some level of inquiry and found that 51% of the studies indicated a positive effect of inquiry-based instruction on the acquisition of conceptual knowledge."

q2 · i? · review · r2

The review attributes to the Alfieri et al. (2011) meta-analysis of 164 primary studies the conclusion that "assisted inquiry is more effective than explicit instruction" while unguided discovery is less effective, indicating guidance is needed for inquiry to pay off.

"Alfieri, Brooks, Aldrich, and Tenenbaum (2011) concluded that unassisted (or unguided) discovery is less effective than explicit instruction, but that assisted inquiry is more effective than explicit instruction"
