The study is also to provide an opportunity for students to adopt the most appropriate way to learn vocabulary and share their topic interest with their classmates to refresh their learning environment and get some improvement in their language competence in the classroom. Via tests, interviews and observation, the researcher has found out that the students here employed determination, social and cognitive strategies in their learning vocabulary, which are derived from Schmitt’s findings (1997) about vocabulary learning taxonomies. Analysis of the data has indicated that the activity has brought some improvement in students’ learning as well as created a lot of fun in the learning environment. From this study, it is concluded that more attention should be paid to refresh the learning environment in the classroom so that the students can be motivated to have much better outcomes.
