This study has attempted to prove that an online glossing tool, WordChamp helped learner to acquire vocabulary items in academic reading passage when compared to other traditional or paper-based strategies or activities. In addition to helping vocabulary learning, WordChamp seems to be effective in enhancing learners'autonomy, and motivation. More importantly, as research shows that most learners use specific strategies and different strategies contribute differently to learners'success, this study should be seen as further evidence to the idea that learners should be provided with a whole array of strategies, letting students choose the most effective one for them, rather than limiting them to the strategies that are thought to be working for all without considering the individual differences.
