In one class of 14 non-science majors, preliminary explicit instruction in scientific reasoning patterns (e.g., IAT statement construction) was followed by a larger average normalized LCTSR gain (68%) than in earlier courses without it (11%, n=42)¶

Subclaims¶

q2 i? A test class with explicit reasoning intervention achieved an average normalized LCTSR gain of 68% (n=14) versus 11% (n=42) in prior similar courses, with DIRECT and TUG-K gains also higher. → Moore 2011

Evidence¶

Moore 2011¶

Moore, J. C., & Rubbo, L. J. (2011). Scientific reasoning abilities of non-science majors in physics-based courses. https://arxiv.org/abs/1110.2764 doi:10.48550/arxiv.1110.2764

q2 · i? · causal · r1

Preliminary test class (15 students from both physics-major and general-education populations) embedded Lawson-style IAT activities and activities targeting proportional, control-of-variables, probability, and correlation reasoning within Physics by Inquiry content. Table III: DIRECT g=0.60 (N=15), TUG-K g=0.55 (N=14), LCTSR g=0.68 (N=14).

"As shown in tab. III, an average normalized gain of 68% (n=14) was achieved on the LCTSR in comparison to 11% (n=42) for previous courses taught similarly with respect to content, though lacking explicit reasoning intervention."

Studies bearing on this claim¶

Does teaching reasoning patterns explicitly develop learners' scientific reasoning more than content instruction or unguided inquiry does? This table gathers the studies behind this claim and the 7 narrower claims that bear on it: 9 distinct studies (4 causal, 2 quant-synthesis, 2 review, 1 theoretical), q1–q4, 2 of 9 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¶

• In physics-based courses for non-science majors taught with active-engagement pedagogy, normalized gains were 0.38–0.42 on content tests but 0.06 on a scientific-reasoning test — related
• Pre-instruction LCTSR scores correlate with normalized learning gains, most strongly for theoretical content (TUG-K r=0.59) and more weakly for descriptive content (DIRECT r=0.50) — related
• Argumentation Improves Reasoning — a broader claim this one bears on
• Productive discourse practices correlate with improved performance on standardized tests of reasoning — related
• Explicit teaching of the control-of-variables strategy shows no advantage over not explicitly teaching it, per the Schwichow et al. meta-analysis cited in the review — related
