Quasi-experiment with two intact classes of first-level female EFL students (n = 40 each) taught the same texts for 11 weeks; the VSSPlus group's post VAT mean was 37.92 versus 23.53 for the VSS group, "statistically significant (t = 25.62, p < 0.05)" with an effect size of 0.894, considered large.

"the mean score of the experimental group on the post VAT was 37.92 with a standard deviation of 2.38, whereas the mean score of the control group on the post VAT was 23.53 with a standard deviation of 2.64"
