Subclaims¶

q3 i? Across meta-analyses, PBL underperforms or matches direct instruction on basic knowledge acquisition but outperforms it on knowledge application, conceptual understanding, and skills. → Manu Kapur 2016

Evidence¶

Manu Kapur 2016¶

Manu Kapur (2016). Examining Productive Failure, Productive Success, Unproductive Failure, and Unproductive Success in Learning. Educational Psychologist, 51(2), 289-299. https://doi.org/10.1080/00461520.2016.1155457

q3 · i? · theoretical · r3

The article synthesizes meta-analytic comparisons of PBL with traditional direct instruction, including Vernon and Blake (1993), Dochy et al. (2003), and Schmidt et al. (2009) meta-analyses of 270 comparisons; no single pooled effect size is printed for this summary pattern.

"Compared to traditional direct instruction, PBL may have a null or an even negative effect on the acquisition of basic knowledge but a positive effect on conceptual understanding and transfer."

Studies bearing on this claim¶

For which outcomes: basic knowledge, application and transfer, or professional skills? This table gathers the studies behind this claim and the 11 narrower claims that bear on it: 8 distinct studies (2 causal, 2 qualitative, 2 quant-synthesis, 1 theoretical, 1 review), q2–q3, 1 of 8 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.
