Subclaims¶

q2 i2 The effect size for K12 studies (E++ = 0.845) exceeds that for higher education studies (E++ = 0.71), and negative effect sizes appear only among higher education studies. → Ergul Sonmez 2021

q2 · i2 · quant-synthesis · r2

Moderator analysis by education level across the 19 included studies, 78.9% of which used university samples. The printed effect sizes are E++ = 0.71 for higher education and E++ = 0.845 for K12, quoted as "0.71 and 0.845, respectively"; the authors state negative effect sizes belonged only to higher education contexts.

"The effect size values for higher education and K12 as two different education levels are 0.71 and 0.845, respectively, of which both values reflect the positive effect."

Discussion¶

Related Claims¶

• Web 2.0 technologies (wikis and blogs) show a positive, moderate pooled effect on academic performance (E++ = 0.740) across 19 quasi-experimental studies — a broader claim this one bears on
• Twelve of the nineteen included studies examined web 2.0 in English as a foreign language teaching, indicating wikis and blogs are concentrated in EFL contexts — related
• Other online technologies (blogging, podcasts, wikis, ARS) show mixed or null effects on grades and exam scores — reports the opposite
