Subclaims¶

q2 i? Elementary EFL students who received direct unfocused WCF scored significantly higher on grammatical accuracy in the revisions of three writing tasks than students who received no error correction. → Khanlarzadeh and Nemati 2016

Evidence¶

Khanlarzadeh and Nemati 2016¶

q2 · i? · causal · r1

Quasi-experimental comparison of two intact classes (experimental n = 16, control n = 17) using one-way between-subjects ANOVA on revision scores. The study reports "a significant difference was found between the grammatical accuracy of the two groups" on all three revisions; no effect size was printed.

"a significant difference was found between the grammatical accuracy of the two groups on revision 1 (F = 8.39, p = .007), revision 2 (F = 6.70, p = .015), and revision 3 (F = 17.35, p = .00)."

Related Claims¶

• The no-feedback control group also significantly improved grammatical accuracy from drafts to revisions — related
• Accuracy gains from unfocused WCF during revision do not extend to a new piece of writing after a one-month interval at the elementary level — related
• Written corrective feedback reduces grammatical errors in EFL post-test writing — a broader claim this one bears on
