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? In one cluster-randomised study, knowledge outcomes were significantly higher in WhatsApp/lectures and LMS/WhatsApp/lectures conditions than in lectures alone, with no difference between the two blended conditions. → Coleman E. 2019

Review's Table 1 summary of the Khan et al. prospective cluster randomisation study (N = 72 across 6 universities, 5 months) comparing lectures, WhatsApp/lectures (W/L), and LMS/WhatsApp/lectures (L/W/L). No effect size printed.
"Knowledge outcomes significantly higher in W/L and L/W/L than lectures but no difference between W/L and L/W/L"
Discussion¶
Related Claims¶
- Seven studies totalling 647 learners reported improved knowledge after WhatsApp-based learning, though methodological weaknesses were apparent
- In the one controlled pre/post comparison, WhatsApp learning and didactic lectures both improved knowledge but did not differ between groups — related
