Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? Experimental-group speaking scores rose significantly from pretest (M=15.75) to posttest (M=18.58) after twenty sessions of PBL with cognition-based tasks. → Ansarian et al. 2016

q3 · i? · causal · r1
Paired-samples t-test comparing the 24 experimental-group participants' IELTS speaking pretest and posttest after the PBL treatment; the article reports "a statistically significant increase" with t(23)=13.22, p=.00. No effect size is printed.
"A paired-samples t-test indicated a statistically significant increase from pre-test (M= M=15.75, SD= 1.15) to post-test [M=18.58, SD= 1.05, t(23)= 13.22, p=.00]"
Discussion¶
Related Claims¶
- The experimental group gained substantially in speaking scores from pre-test to post-test — possibly the same claim (merge candidate)
- Control group showed only slight speaking gains from pre-test to post-test — related
- Before treatment, the cognition-based and objective-based groups did not differ significantly in speaking proficiency — related
- Authentic problem-based vocabulary tasks improve immediate vocabulary recall of intermediate Iranian EFL learners compared with conventional input-based tasks — related
- The experimental group improved significantly from pre-test to post-test in overall speaking proficiency, with a large within-group effect — related
