MWITA-XR-2026-010 · Evidence B · P1
A 2026 South African student study found participants reported subtitles enhanced understanding and engagement more than dubbing across academic English, plain English and home-language versions.
What this does not establish
Self-reported preference is not an objective learning-effect estimate and does not establish that dubbing is ineffective.
Counterevidence & uncertainty
Course, language proficiency and localization quality can alter preference.
What would change the reading
Add randomized comprehension and retention comparisons across African languages.
