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.
q1 i? The article reports, citing Charles and Trenkic (2015), that learners exposed to bimodal input (a video with captions) improved their listening skills relative to a control group, with improvement generalizing to unfamiliar sentences and speakers. → Darcy 2018

The article attributes this finding to Charles and Trenkic (2015), saying the improvement "generalized to sentences and speakers whom the learners were not familiar with," suggesting a long-term effect on word-recognition ability from running speech.
"A relevant recent study by Charles and Trenkic (2015) demonstrated that learners who were exposed to “bimodal input,” that is, a video with captions, improved their listening skills (as opposed to a control group)."
Discussion¶
Related Claims¶
- On-screen text that duplicates the narration of a diagram can hurt learning, but spoken–written redundancy is not harmful on average and helps over spoken-only presentation in some conditions — the general claim this finding bears on, with the studies behind it
- Redundant on-screen text impairs learning when it competes with a visualization, though written text duplicating narration alone can help — related
- Captioning second-language videos produces large benefits for comprehension and vocabulary acquisition — a broader claim this one bears on
