Podcasting is a recent phenomenon that is capturing an attention from different sectors of education. Many people have not heard about podcasting but there are many who use podcasts for different purposes. Some of them listen to podcasts to get different kind of information, others, especially language learners – to enhance their vocabulary and listening skills outside the classroom. Thus, podcasts can become a useful tool for language teaching and learning, especially for developing students’ vocabulary, listening and speaking skills. The purpose of this study was to explore if there is a difference between developing adult EFL learners’ word stock and listening skills with and without using podcasts. The study involved 165 students of different English proficiency levels, ages, and genders. Data were collected using pre- and post-listening tests and interviews. The results of the tests show that there was a big difference between the two groups’ listening comprehension skills performances. The findings also indicate that EFL students learned more words by listening to podcasts and doing post-listening activities. Additionally, most of the learners’ attitudes towards podcasts were positive; as during the interviews they mentioned that podcasts were very motivating. They said that it was more interesting and easier to learn new words and develop their listening and speaking skills with the help of podcasts. Therefore, they would like to listen to podcasts and do post-listening activities while learning language. Taking into consideration the findings of this study it is recommended to use podcasts with different kind of activities during language teaching.
