Subclaims¶

q2 i1 The review reports, citing Alfieri et al. (2011), that inquiry with minimal or no guidance is less effective than explicit instruction (d = -0.38), whereas guided inquiry outperforms expository teaching of the same content (d = 0.30). → Lazonder 2016

q2 · i1 · quant-synthesis · r3

Narrative review section reporting a prior meta-analysis; the review attributes to Alfieri et al. (2011) that "inquiry-based methods with minimal or no guidance are less effective than explicit instruction" while adequately guided inquiry beats expository methods. Design of the original meta-analysis is not described here.

"Alfieri et al. (2011) found that across domains and settings, inquiry-based methods with minimal or no guidance are less effective than explicit instruction (d = −0.38). But when students receive adequate guidance during the inquiry, they learn more (d = 0.30) than students who are taught the same content by expository methods."

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 — the general claim this finding bears on, with the studies behind it

- - Relatively guided instructional procedures are more effective than relatively unguided procedures for novice students — related - Guided discovery outperformed both unguided discovery and direct instruction in classic studies — possibly the same claim (merge candidate) - Prior studies reviewed show exploratory learning outperformed proceduralized instruction for training performance and transfer — reports the opposite - Guidance during inquiry learning produces a medium-to-large improvement in learners' use of inquiry skills during the inquiry — related - Enhanced discovery learning produces greater learning than other forms of instruction — possibly the same claim (merge candidate) - Teacher Guided Inquiry Outperforms Student Led — related - Inquiry Based Teaching Improves Science Achievement — related - Minimally guided instruction is less effective and less efficient than instruction that places a strong emphasis on guidance of the student learning process — a broader claim this one bears on - Meta-analysis of 164 studies found assisted inquiry more effective than explicit instruction — possibly the same claim (merge candidate) - Controlled studies comparing exploration-based investigation with explicit instruction overwhelmingly favor explicit instruction for science content learning — related
