Subclaims¶

q3 i? Pre–post effect size estimates of scaffolding are highest among college- and graduate-level learners, at ḡ = 1.16 and ḡ = 1.2 respectively. → Belland Brian R. 2017 q3 i? College ranked first with a 35% chance and graduate second with a 47% chance of being the best education level for scaffolding gains. → Belland Brian R. 2017 (2)

Evidence¶

Belland Brian R. 2017¶

Belland Brian R., Walker Andrew E., Kim Nam Ju. (2017). A Bayesian Network Meta-Analysis to Synthesize the Influence of Contexts of Scaffolding Use on Cognitive Outcomes in STEM Education. Review of Educational Research. https://doi.org/10.3102/0034654317723009

q3 · i? · quant-synthesis · r2

Bayesian network meta-analysis results for the education level moderator (Figure 3), showing highest estimates at college (ḡ = 1.16) and graduate (ḡ = 1.2) levels; the article notes some true effects were below zero for all educational levels except college.

"Pre–post effect size estimates are highest among college- and graduate-level learners, at ḡ = 1.16 and ḡ = 1.2, respectively (see Figure 3)."

Belland Brian R. 2017 (2)¶

q3 · i? · quant-synthesis · r2

Ranking and probability-of-the-best analysis across education levels (Table 1): college ranked 1.98 with 35% probability of the best; graduate ranked 2.32 with 47%; secondary ranked 4.5 with 2%.

"Scaffolding led to the highest pre–post gains at the college and graduate levels (see Table 1), ranked first and second with a 35% and a 47% chance of being the best, respectively."

Discussion¶

Related Claims¶

• Scaffolding produces strong pre–post gains across all assessment levels (concept ḡ = 0.87 to application ḡ = 0.74), with only minor differences among levels — related
• Scaffolding yields strong pre–post gains with most problem-centered instructional models, with project-based learning highest (ḡ = 1.21), but exceptions for inquiry-based learning (ḡ = 0) and modeling/visualization (ḡ = 0.28) — related
• Mathematics and technology show the highest pre–post scaffolding effect sizes among STEM disciplines (ḡ = 1.29 and ḡ = 1.06) — related
• Scaffolding's effect was greatest among adult learners, though based on a single outcome — reports the opposite
