Open access · cc by · source: Europe PMC
Text-based CMC boosted autonomy and cognitive/behavioral engagement, while multimodal CMC boosted emotional and social engagement.

Key findings
Text-based modality produced stronger autonomous, behavioral, and cognitive engagement; multimodal modality produced stronger emotional and social engagement. Satisfaction was similar across modalities.
Methodology
Forty intermediate Iranian EFL learners were randomly assigned to text-based or multimodal computer-mediated communication groups for fourteen treatment sessions. Researchers compared autonomy, multi-dimensional engagement, satisfaction, and first-to-last writing performance.
Limitations
Results are from one EFL context with a modest sample and may not generalise broadly. Engagement measures and writing gains are limited to the fourteen-session window.
How this study connects
Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
Technology choice and modality shape observable participation: mobile instant messaging and text-based CMC can increase interaction or behavioral engagement relative to forum or multimodal alternatives in specific course designs.
Evidence for the claim as stated.
Some studies treat behavioral engagement as an outcome of tool modality, while others treat it as a predictor of technology engagement — so direction of effect depends on the research question, not a single causal story.
Evidence for the claim as stated.
Multimodal CMC can boost emotional and social engagement even when text-based CMC better supports autonomy and behavioral/cognitive engagement.
Evidence for the claim as stated.
What moves is not always engagement. Chatbot students gained on course performance (d ≈ 0.98) without significant affective/motivation differences. Forty Iranian EFL learners randomised to text-based versus multimodal CMC for fourteen sessions split engagement by dimension (text-based stronger on autonomous, behavioural and cognitive; multimodal on emotional and social) with similar satisfaction. A pre/post 'engagement improved' headline would mis-state both papers.
Evidence for the claim as stated.
Forty intermediate Iranian EFL learners (20 text-based, 20 multimodal; fourteen sessions) split engagement: text-based stronger on autonomous, behavioural and cognitive dimensions; multimodal on emotional and social; satisfaction similar. A single 'engagement effect size' would have hidden that split. The window is fourteen sessions in one EFL context.
Evidence for the claim as stated.

Evidence for the claim as stated.
Unit of randomisation and what 'worked' disagree across the three papers. Classrooms were assigned in the mentoring study, so baseline enrolment size is a cluster confounder and the average treatment effect was null. Individuals were assigned in the CMC and ITS studies, which can show average gains in engagement or posttest scores without speaking to school-level implementation. Reading all three as 'RCTs of teaching' hides that.
