Interest in the use of a mobile phone to access the Internet for learning English in general, and listening skills in particular, has been increasing in Korea over the last few years. However, there has been only a small number of studies on this topic in Korea. The present paper investigates the potential of using a mobile phone to browse wireless application protocol (WAP) sites for the purpose of learning listening skills. The study focuses specifically on the attitudes of language learners toward using a mobile phone for this purpose. The study is based on input, interaction, output and sociocultural theories, as well as on collaborative, learner-centred, constructivist and task-based learning approaches. An experiment was carried out with a group of undergraduate students who had enrolled in a required intermediate English as a Foreign Language (EFL) listening course at a Korean university. A WAP site was designed and used as the instrument for the experiment. This study found that the language learners expressed positive attitudes towards the use of the WAP site. It also found that the WAP site can be effective for learning listening skills and for student-centred and collaborative learning. Based on the findings, it is clear that WAP sites can be effective for learning listening skills, since they can enhance opportunities to learn language skills, and encourage language learners to participate actively in the learning process.
