Golfam Masoudi. (2017). The Effect of Vocabulary Self-Selection Strategy and Input Enhancement Strategy on the Vocabulary Knowledge of Iranian EFL Learners. English Language Teaching, 10(8). https://doi.org/10.5539/elt.v10n8p32

q2 · i? · causal · r1

Independent-samples t-test comparing the two 20-learner experimental groups on the 50-item seen posttest after the three-month treatment, with Levene's test showing homogeneity of variance (significance 0.369). The mean of the Vocabulary Self-Selection group was higher, so the null hypothesis was rejected.

"The results of the independent t-test (t=12.56, df=38, p=0.000>0.05) indicated that there was statistical ly significance between the learners who were exposed to V ocabulary Self-Selection strategy and Input Enhancement strategy"
