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.
q2 i? After ten sessions of watching subtitled clips, the bimodal subtitling group obtained the highest posttest vocabulary mean (41.2) versus 34.9 without subtitles and 30.0 for control, with a statistically significant difference among groups. → Sirmandi and Sardareh 2016

q2 · i? · causal · r2
Three-group experiment with 60 intermediate Iranian EFL learners (20 per group) watching ten BBC World clips over ten sessions; posttest means were 41.2 (subtitle), 34.9 (no subtitle), and 30.0 (control), and "the group with bimodal subtitles significantly outperformed the other groups".
"As shown in Table 2, the group with bimodal subtitles significantly outperformed the other groups and had the highest mean score. The experimental without subtitle group performed better in the posttest than the control group."
Discussion¶
Related Claims¶
- One-way ANOVA on posttest scores showed a statistically significant difference among the subtitle, no-subtitle, and control groups (F = 84.161, Sig. = .000) — a narrower finding that bears on this claim
- Watching BBC World clips without English subtitles also improved intermediate EFL learners' vocabulary development relative to no treatment — related
- Watching cartoons with English subtitles produces no statistically significant vocabulary-gain advantage over watching without subtitles among upper-intermediate ELT students — reports the opposite
- The three groups did not differ significantly in vocabulary knowledge at pretest, supporting group homogeneity — related
- Vocabulary improvement occurred incidentally regardless of subtitles, attributed to target words being contextualized in the cartoons — related
