Subclaims¶

q3 i2 Across 56 primary studies, the overall mean effect size favoring CMC over face-to-face or non-computer-mediated communication was d = .554, with a 95% confidence interval of .482 to .626, described as a small to medium effect. → Lin 2012

q3 · i2 · quant-synthesis · r2

Meta-analysis of 56 eligible empirical studies (2000–2011) using experimental or quasi-experimental designs; effect sizes were Cohen's d, weighted and corrected for small sample sizes. The meta-analysis reports "The overall effect size is .554, with 95% confidence interval between .482 and .626."

"The overall effect size is .554, with 95% confidence interval between .482 and .626."

Discussion¶

Related Claims¶

• A majority of CMC studies (79%) produced effect sizes favoring CMC, while 21% favored face-to-face or non-computer-mediated communication — related
• Small group sizes produced the largest CMC effect compared with no grouping or groups of more than 3 students — a narrower finding that bears on this claim
• SCMC interaction shows a small, non-significant advantage over FTF on overall L2 learning outcomes — related
