The World Wide Web offers a global database of authentic materials that can enhance language learning and teaching. This study examines the use of the web for language learning through a study of English as a second language (ESL) learners' experiences in web-based language learning (WBLL) activities in an English language intensive course for overseas students (ELICOS) context. It observes ESL learners performing selected activities on the web and investigates their perceptions and attitudes toward the web activities. A group of students was guided to utilise the web to complete two types of web activities (i.e., pre-created web activities and task-based web activities). Data collected demonstrate that the web is a useful tool and a supplementary resource for learning ESL. The students' engagement in the suggested activities was observed and their attitudes toward the activities were found to be positive. Further studies are recommended to increase our understanding and knowledge of how WBLL can be best used for specific learners in specific contexts.
