Subclaims¶

q2 i2 Correctly retrieved paired-associates correlated with VST gains at r = .311, significant at the 0.01 level (n = 125). → McLean 2013 q2 i2 Acquired words correlated with VST gains at r = .32, significant at the 0.01 level (N = 125). → McLean 2013 (2)

q2 · i2 · associational · r1

Correlational analysis of Word Engine monitoring data against VST gains for research question 3. Table 6 reports r = .311, significant at the 0.01 level (2-tailed), n = 125; the text calls it "a medium-strength relationship between these two variables".

q2 · i2 · causal · r1

Correlational analysis of acquired words (six consecutive correct retrievals over 90 days) against VST gains for research question 4. Table 7 reports r = .32, significant at the 0.01 level (2-tailed), N = 125; the text calls it "a medium-strength relationship".

• Raw VST gain scores did not support that two hours of weekly Word Engine use produced greater gains than one hour — related
• Classes assigned weekly Word Engine online flashcard use gained significantly more on the VST than an extensive-reading control class over one academic year, in a quasi-experiment with acknowledged selection and time-on-task confounds — related
• Cumulative correct answers on blended-workshop activities relate to final exam score, but number of attempts does not — related
