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 15 weeks, the experimental group taught with video files scored significantly higher than the control group on a 40-item multiple-choice reading comprehension post-test (p = 0.000). → Mohammadian et al. 2018

q2 · i? · causal · r1

Quasi-experiment with 30 male high-school learners in Chabahar, Iran, split into control and experimental groups of 15 each. Post-test means were 23.80 (video group) versus 19.80 (control); the "difference was statistically significant (p= 0.000)". No effect size is printed.

"the independent-samples t-test analysis showed that this difference was statistically significant (p= 0.000). Hence, it can be surely said that there were statistically significant differences between the experimental and control groups on the post- test in overall reading in favor of the experimental group."
