3.2 TOEIC
Table 4 presents descriptive statistics. A one-way ANOVA showed that there was no statistically significant difference among the groups on the TOEIC pretest, F(2, 94) = 1.82, p = .17. A tests (two tests) by groups (three levels) repeated-measures two-way ANOVA revealed a statistically significant difference within the participants, F(1, 85) = 53.71, p = 00, showing that all groups gained, but there was no statistically significant difference among the groups, F(2, 85) = 2.25, p = .11, and the interaction was not significant. F(2, 85) = .20, p = .82 (Table 5).
