Subclaims¶

q3 i? Pre-intermediate learners taught with CAVI scored significantly higher on the vocabulary post-test than pre-intermediate learners taught by the teacher-led method. → Nejati 2018 q3 i? Before treatment, the pre-intermediate CAVI and teacher-led groups did not differ significantly in vocabulary knowledge, supporting attribution of the post-test difference to the treatment. → Nejati 2018 (2)

Evidence¶

Nejati 2018¶

Nejati, E., Jahangiri, A. & Salehi, M. R. (2018). The effect of using computer-assisted language learning (CALL) on Iranian EFL learners’ vocabulary learning: An experimental study. Cypriot Journal of Educational Science. 13(2), 351–362. https://eric.ed.gov/?id=EJ1183258

q3 · i? · causal · r1

Independent-sample t-test on post-test scores of the pre-intermediate groups (n = 10 per group as printed in Table 5) after eight CAVI or teacher-led sessions. The CAVI group mean of "M = 35.4667" exceeded the teacher-led mean of "M = 30.0667"; Table 6 reports t = 4.316, df = 28, Sig. 0.000.

"As seen in Table 6, the mean score of the CAVI group ( M = 35.4667) is considerably higher than the teacher-led group (M = 30.0667)."

q3 · i? · causal · r1

Independent-sample t-test on pre-test scores of pre-intermediate groups (n = 10 per group, Table 3): CAVI M = 2.2667 vs teacher-led M = 2.5333, Sig. 0.645, indicating no statistically significant pre-treatment difference; equivalence was not formally tested.

"the t-test result ( 0.645) shows that there is no meaningful distinction between the means of the two groups in the pre -test be fore the administration of the treatment."
