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? The interaction between learning environment and pretest-posttest measurement on success is significant, with the WhatsApp-supported environment more effective (F(1-58)=90.14, p<.001). → Cetinkaya 2017

q2 · i? · causal · r2

Quasi-experimental pretest-posttest control group study with 60 10th-grade students (30 per group); two-factor variance analysis for mixed measurements. Experimental posttest mean was 19.63 (S=4.41) versus control 11.57 (S=3.41), from pretest means of 3.60 and 3.83; the "common effect" of environment and repeated measures was significant.

"the common effect of being in a different environment and the factors of repeated measures on success is significant (F(1-58)=90.14, p<.001). This finding shows that both learning environments have different effects on increasing the success of students."
