The Comparative Effect of Visual vs. Auditory Input Enhancement on the Learning of Non-congruent Phrasal Verbs by Iranian EFL Learners

Vocabulary is one of the essential components of language and phrasal verbs as part of vocabulary pose more challenges to foreign language learners. The present study aimed at finding the effects of visual and auditory input enhancement on the learning of non-congruent phrasal verbs. The participants of the current study were 90 intermediate English language learners who were divided into two experimental and one control group. One experimental group received visual and the other auditory input enhancement. The groups of the study were tested on their knowledge of non-congruent phrasal verbs before and after the treatment using a non-congruent phrasal verb test developed by the researcher. The results of data analyses indicated that both visual and auditory input enhancement were effective in learning non-congruent phrasal verbs by Iranian EFL learners; however, there was no significant difference between the two groups. The results of the study were discussed in the light of previous theories and empirical studies, and at the final stage of the research, the implications for language learning were presented.
