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? Overall interview score improvement was statistically significant for the trial cohort (p = 0.024); lexis (p <0.000), pronunciation (p <0.000) and discourse (p <0.034) improved, grammar did not (p <0.074). → Robert Alexander Graham Coates 2017

Interview test scored 1-5 in half points by qualified FCE examiners blinded to cohort, based on Cambridge criteria (grammar, pronunciation, discourse, lexis); interviews lasted 3-5 minutes. Table 4 reports Total F 5.59, t 2.364, p 0.024."statistically relevant for the overall score (p = 0.024)"
"The improvement in the trial cohort was statistically relevant for the overall score (p = 0.024) and for pronunciation (p <0.000), discourse (p <0.034) and lexis (p <0.000), although not for grammar (p <0.074)."
Discussion¶
Learner Variables¶
- Communication Skills — outcome: instruction changes it
Related Claims¶
- The phonics trial technique was statistically more efficient than traditional exam preparation despite the control cohort receiving more exam practice — a broader claim this one bears on
- The trial group improved L2 pronunciation (grapheme-phoneme decoding) significantly, driven mainly by the digraph category — related
- Guided ASR practice improves overall pronunciation accuracy of Korean EFL learners more than ordinary classroom pronunciation practice alone — related
