Abstract- The aims of this study are to understand the ways that web-based social networking can be used to provide English as a scond language (ESL) students with the opportunity to use english, and to reflect on and improve our own practice with view to create an atmosphere where web-based social networking can be used as a medium to enhance students’ interaction in the language. The subjects of this study are members of English speaking zone (ESZ) facebook group-a group created and maintained by the researchers-for students in a residential college at university kebangsaan Malaysia (UKM). We used an action research methodology because our intention was to improve our own practice and to learn from the participants. We analyzed the data gathered from the content analysis of the interactions on the facebook group and also conducted interviews with 20 participants. The results show that the interactions (number of posts) in ESZ facebook differ according to different phases of the use of the technology.
