(2) What are the effects of using multimedia in helping students at Crazy Ones English Center in learning pronunciation? Methods of the study This study employs both qualitative and quantitative methods To reach the aim of the study, the researcher intends to carry out an action research at Crazy Ones English Center Scope of the Study This study focuses on using multimedia for teaching pronunciation to Pre- LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com learning pronunciation Students felt more exciting when studying at class because of interesting activities using multimedia in the lessons Multimedia also provided effective tools for students to prepare and study pronunciation better at home Futhermore, students got improvement in pronuncing English sounds, stress, rhythm, linking, and intonation Besides, the author comes up with some implications to the application of multimedia in teaching and learning English pronunciation It is important to apply multimedia in order to improve English learning and attitude of students in classroom Also, interaction between teachers and students and students and students can be improved Moreover, students can be autonomic in learning to be well prepared before going to class Besides, Exciting and relaxing learning environment can be made by using multimedia when teaching English at class Additionally, to compare with traditional teaching, multimedia focuses more on "learner-centered" Furthermore, learner-controlled is high considered because students can decide when, how long and where to study and practice learning English However, to apply multimedia effectively, teachers should be aware of recommending students with the information and knowledge from multimedia because they need good guides from teachers to know how and what to learn To so, teachers also need to train themselves to prepare for teaching using multimedia Because new problems can always occur when teaching, good teachers should be ready for researching and finding solutions to improve their teaching practice Limitations and suggestions for further study The study was conducted from a small size of participants and at a particular English center This may lead to the lack of full understanding of pronunciation problems that students face with The study only researched for the pre-intermediate students and at a classroom with sufficient equipment It limits to others levels of students and classroom outside the center 37 LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com The study needs more time to evolve with the most suitable for the specific class Although this multimedia shares advantages as well as challenges in teaching pronunciation, one of the key of principles of teacher development that urges teachers to be positive and motivated in teaching is “opportunities and support for creative activity” (Hargreaves and Goodson, 1996: 20-21) Because of the limitations, the author hopes that further study will be conducted to gain better understanding of using multimedia to teach pronunciation to a wider range level of students and at other English centers and institutions In this study, multimedia were only used to teach pronunciation so the author also hopes that further study will be made to apply multimedia into helping students improve English learning in getting knowledge and language skills like vocabulary, listening, speaking, reading and writing 38 LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com REFERENCES Allwright, R L (1984) The Importance of Interaction in Classroom Language Learning Applied Linguistics Banerji, A., & Ghosh, A M (2010).Multimedia technologies New Delhi, India: Tata McGraw Hill BBC Learning English | Pronunciation Tips (n.d.)
