Furtak and colleagues meta-analyse experimental and quasi-experimental studies of inquiry-based science teaching to estimate effects and examine how instructional guidance matters. Across 37 studies yielding 42 independent effect sizes, inquiry instruction had a positive overall effect on student learning.
Effects varied by the kind of cognitive activity emphasised and by the degree of teacher guidance. Approaches involving epistemic activities—using evidence and reasoning to develop or justify knowledge—showed particularly strong results, while teacher-led guidance within inquiry was more effective than interpretations that left students to discover procedures and concepts with little support. The review therefore challenges the false choice between direct teaching and unguided inquiry. Productive inquiry involves carefully designed questions, disciplinary practices, scaffolding, feedback, and explicit support calibrated to learners and goals.
The authors also note variation in study quality, outcome measures, samples, and definitions of inquiry. Educational decisions should focus on which inquiry processes are taught and supported, not whether an activity merely carries the inquiry label.
A transparent research trail
Each entry identifies the volume, edition, chapter or appendix in which the work appears.
Evidence summaries explain the central idea and why the source matters to educators.
Entries link to lawful full text where available, or to a publisher, library or purchase page.
References are checked against publisher records, scholarly indexes, DOI or ISBN metadata, repositories and author records where available. An entry marked [Citation not verified] preserves the wording found in the relevant volume without attributing findings to an unconfirmed work.
