Subclaims¶

q2 i? Feedback focus, rather than feedback type, was the more telling factor: focused feedback had a positive effect size in both DCF and ICF in all cases. → Albatool Abalkheel & Tara Brandenburg 2020 q2 i? Comprehensive feedback demonstrated negative effect sizes for all DCF studies and mixed results (half negative, half positive) for comprehensive ICF studies. → Albatool Abalkheel & Tara Brandenburg 2020 (2)

Evidence¶

Albatool Abalkheel & Tara Brandenburg 2020¶

Albatool Abalkheel & Tara Brandenburg. (2020). Effects of Written Corrective Feedback: A Synthesis of 10 Quasi-Experimental Studies. English Language Teaching, 13(7). https://doi.org/10.5539/elt.v13n7p97

q2 · i? · quant-synthesis · r1

Cross-study comparison in the meta-analysis (Table 3) of effect sizes by CF type and focus. The synthesis reports that "focused feedback had a positive effect size in both DCF and ICF", though focused ICF was supported by only one study.

"What proved to be more telling of the efficacy of feedback was the focus, rather than the type of feedback. In all cases, focused feedback had a positive effect size in both DCF and ICF."

q2 · i? · quant-synthesis · r1

Same synthesis of effect sizes by focus (Table 3). Comprehensive feedback showed "negative effect sizes for all DCF studies" and split results for comprehensive ICF, with Lalande (1982) and Van Beuningen et al. (2011) negative and Truscott & Hsu (2008) and Hartshorn et al. (2010) positive.

"On the other hand, the results for comprehensive feedback demonstrated negative effect sizes for all DCF studies and mixed, with half negative (Lalande, 1982; VanBueningen et al., 2011) and half positive (Truscott & Hsu, 2008; Hartshorn et al., 2010) for comprehensive ICF studies."

Discussion¶

Related Claims¶

• Direct versus indirect written corrective feedback proved inconclusive: DCF showed five large positive and two negative effects, ICF results were split — related
• In the Sheen et al. (2009) study, focused direct CF produced a large positive effect while unfocused (comprehensive) direct CF produced a large negative effect — a narrower finding that bears on this claim
• The Van Beuningen et al. (2011) study of comprehensive CF showed overall negative effect sizes across high and low proficiency groups — related
