Abstract

The aim of the present study was to investigate the effect of pronunciation forms on improving Iranian EFL learners’ knowledge of vocabulary. To achieve this purpose, fifty participants pre-intermediate language learners were selected based on their scores on a knowledge of vocabulary test and were randomly assigned to two groups. Each group was exposed to as pre-test and post-test. At the end of the experiment, to see whether or not any changes happened regarding their lexical knowledge, a post-test was administrated to two groups. The results suggested that the participants performed differently on the post-test indicating that teaching lexical through rehearsal and pronunciation forms promotes the Iranian EFL learners’ knowledge of vocabulary.

Key Words

Knowledge of pronunciation forms, Pronunciation Awareness (PA), Morphological awareness, Phonemic awareness, LK or knowing a word.
