The Impact of Applying Images on Knowledge of Affixes among EFL Learners

The aim of the present study was to investigate the effect of Applying Images on Iranian EFL learners’ Knowledge of Affixes. Based on a standard PET test, 60 learners selected out of 100 intermediate female EFL learners were chosen in the study. They were assigned randomly to one control and one experimental group. Then an affix test was given to them as a pretest. The experimental group received instruction through images as their treatment while the control group has their own way of teaching without treatment. After treatment, both groups were given an affix posttest again. The results were analyzed through sample independent ttest in order to see if there was any significant difference in the results. The results (t = 8.245, p = 0.000 0.001) show that there is a significant difference between the scores of the two groups at the final exam. Thus, it is concluded that the participants of the experimental group strongly outperformed the control group in the final exam. The findings of this study have implications for students, teachers, and syllabus designers.
