Subclaims¶

q2 i? The experimental group's SQL Final Test scores were significantly higher than its SQL Mid-Test scores (Wilcoxon Signed-Rank z=2.407, p<.05), which the authors describe as a slight but significant improvement. → Yavuzarslan 2019

Evidence¶

Yavuzarslan 2019¶

Yavuzarslan, M., Olgun, H., & Yazici, S. (2019). A Pilot Study on the Comparison Between Blended and F2F Learning Methods in a SQL Course. The Turkish Online Journal of Educational Technology. https://eric.ed.gov/?id=ED602380

q2 · i? · causal · r2

Within-group Wilcoxon Signed-Rank comparison of the experimental group's (n=22) SQL Mid-Test (mean 29.55) and SQL Final Test (mean 43.07) scores after two weeks of blended learning. The article reports a statistically significant difference with no effect size; both means were below the expected mean.

"According to the results shown in Table 8, there was a statistically significant difference between the mean scores of SQL Mid-Test and mean scores of SQL Final Test of the experimental group (z=2.407, p<.05)."

Discussion¶

Related Claims¶

• Undergraduate students taught SQL face-to-face performed significantly higher on the SQL Final Test than students taught with a blended learning method over a two-week experiment — related
• The authors argue the two-week experiment was too short for participants to acquire SQL skills, explaining the blended group's lower performance — related
