An Investigation of the Differential Effects of Visual Input Enhancement on the Vocabulary Learning of Iranian EFL Learners

Zhila Mohammadnia, Abdolreza Khalili

Abstract


This study investigated the effect of visual input enhancement on the vocabulary learning of Iranian EFL learners. One hundred and thirty-two EFL learners from elementary, intermediate and advanced proficiency levels were assigned to six groups, two groups at each proficiency level with one being an experimental and the other a control group. The study employed pretests, treatment reading texts, and posttests. T-test was used for the analysis of the data. The results revealed positive effects for visual input enhancement in the advanced level based on within group and between groups’ comparisons. However this positive effect was not found for the elementary and intermediate levels based on between groups’ comparisons. It was concluded that although visual input enhancement may have beneficial effects for elementary and intermediate levels, it is much more effective for the advanced EFL learners. This study may provide useful guiding principles for EFL teachers and syllabus designers.
