Subclaims¶

q4 i1 Across 360 comparisons, outcomes favored enhanced discovery (generation, elicited explanation, guided discovery) over other instruction, d = 0.30, 95% CI [.23, .36]. → Alfieri 2011

Evidence¶

Alfieri 2011¶

Alfieri, L., Brooks, P. J., Aldrich, N. J., & Tenenbaum, H. R. (2011). Does Discovery-Based Instruction Enhance Learning? Journal of Educational Psychology, 103(1), 1–18. https://doi.org/10.1037/a0021017

q4 · i1 · quant-synthesis · r2

Random effects meta-analysis of 360 comparisons from 56 studies comparing enhanced discovery (generation, elicited explanation, guided discovery) with other instructional methods. The pooled effect favored enhanced discovery, d = 0.30 (95% CI [.23, .36]), small but meaningful (p < .001), with high heterogeneity.

"In contrast, analyses of 360 comparisons revealed that outcomes were favorable for enhanced discovery when compared with other forms of instruction ( d = 0.30, 95% CI [.23, .36])."

Studies bearing on this claim¶

Does discovery with guidance (prompts, feedback, worked examples, elicited explanations) produce more learning than unassisted discovery or other instruction? This table gathers the studies behind this claim and the 5 narrower claims that bear on it: 6 distinct studies (4 quant-synthesis, 1 theoretical, 1 design), q2–q4, 3 of 6 with an effect size coded. One row per study, codes as each entry records them; no effect is averaged and no verdict is drawn. Built by scripts/synthesize_claim.py from eval/synthesis/; a row that looks wrong is fixed on the claim it comes from.

Discussion¶

Related Claims¶

• Guidance during inquiry learning improves post-inquiry learning outcomes (d = 0.50) — the general claim this finding bears on, with the studies behind it
• Unassisted discovery produces less learning than explicit instruction, while discovery enhanced with guidance outperforms other instruction — possibly the same claim (merge candidate)
• Productive Failure Improves Conceptual Learning — related
• Teacher Guided Inquiry Outperforms Student Led — related
• The advantage of explicit instruction over unassisted discovery is largest in the verbal/social skills domain — related
• Studies comparing pure simulation-based discovery learning with expository teaching show no clear and univocal outcome in favor of simulations — related
• Effects of discovery-related approaches are differential, not uniform across students or learning goals — related
• Guided discovery outperformed both unguided discovery and direct instruction in classic studies — related
• Guided play outperforms direct instruction or free play on a few early-childhood outcomes, with no reliable difference on most others, in one meta-analysis — related
• Dependent measure moderates discovery effects: acquisition scores amplify the explicit-instruction advantage, and reaction-time measures reverse the enhanced-discovery advantage — related
• Inquiry Based Teaching Improves Science Achievement — related
• Guidance during inquiry learning produces a medium-to-large improvement in learners' use of inquiry skills during the inquiry — related
• Minimally guided or unguided inquiry is less effective than explicit instruction, while adequately guided inquiry outperforms expository instruction (review attribution to Alfieri et al., 2011) — possibly the same claim (merge candidate)
• One review reports that more teacher guidance within inquiry is associated with larger advantages over traditional instruction, though the two meta-analyses it cites differ in magnitude — related
• Instructional approaches that include inquiry learning are more effective than direct instruction for acquiring conceptual knowledge, per the review's synthesis of meta-analyses — related
• Well-controlled comparison studies show clear advantages of inquiry-based instruction over direct instruction for science conceptual learning — related
• Controlled studies comparing exploration-based investigation with explicit instruction overwhelmingly favor explicit instruction for science content learning — reports the opposite
