Between-groups experiment: 60 intermediate learners selected from 140 via QPT, randomly assigned to two groups of 30. Independent samples t-test on post-test fluency gave t = 4.969, df = 58, Sig. (2-tailed) = .000, mean difference 1.9733; means were "12.020" (experimental) vs "10.047" (control).

"The results of applying independent samples t-test for comparing the means of the post-tests of experimental and control groups showed that there were significant differences between the performances of the two groups in the post-test."
