STUDENTS IN THANH HOA Field: Teaching English to Speakers of Other Languages(TESOL) Code: 60.14.01.11 MASTER’S THESIS IN EDUCATION Supervisor: Dr Tran Thi Ngoc Yen Nghệ An, 2017 i STATEMENT OF AUTHORSHIP I hereby acknowledge that this study is my own work The data and findings discussed in the thesis are true and have not been published elsewhere Author Nguyen Thi Thanh Huyen i ABSTRACT This study was set out to determine if the use of subtitled English videos enhances EFL high school students’ incidental vocabulary learning The students participating in the experiment aged around 16 years old and were divided into three groups, one being the control group and the other two the experimental groups During the treatment time, each experimental group was asked to watch short video clips, either with English subtitles or dual subtitles A vocabulary level test was used as the pre- and post-treatment test to determine whether watching these videos played a role in the participants’ vocabulary learning The data revealed that the three groups did better in the post-test, but there was a significant difference between the experimental groups and the control group It was also found that the two experimental groups did similarly well The data collected from the questionnaire showed that the use of subtitled authentic videos motivated EFL students’ vocabulary learning In addition, participants have positive attitudes toward learning from subtitled videos, both inside and outside schools’ boundaries The study suggested that subtitled videos can be used as an effective learning tool in the second language classroom ii ACKNOWLEDGEMENTS I would like to express my deep gratitude to my supervisor, Dr TRAN THI NGOC YEN, who I believe is the most wonderful supervisor, for her valuable time, suggestions, guidance, warm encouragement, and continuous support throughout this study Without her help, my study would not have been completed I also wish to thank

multimedia technology for both in my teaching and searching I have made a great effort to keep abreast with these developments by using technology to create and exploit learning opportunities for my students I would like to encourage students’ interest in subtitled authentic videos and make them feel confident when using such videos as learning tools It’s the teacher’s duty to put students in a position where they are capable of increasing their knowledge of vocabulary independently of the teacher by looking at the subtitled words in meaningful and stimulating circumstances I decided to carry out the current study to determine whether subtitled authentic videos could be effective vocabulary learning tools for Thanh Hoa EFL high school students 1.2 Aim of study This study aimed to demonstrate that watching the English subtitled videos will improve EFL high school students’ knowledge of English vocabulary and to determine whether the participants felt that the subtitles accompanying the treatment video motivate them 1.3 Research questions This research aims to answer the following questions: - How does the use of English subtitled videos affect EFL high school students’ vocabulary learning? - Will the use of English subtitled videos help to motivate EFL high school students to learn English? 1.4 Scope of study This research focuses on the effect of using English subtitled videos as vocabulary learning tools for Thanh Hoa EFL high school students The study is to determine which subtitled video( English subtitled video or English and Vietnamese subtitled First, as the comparative effect of the two subtitle types investigated in this study for learners with Vietnamese background remains unclear, this research can be replicated with more participants, avoiding the limitations of the vocabulary tests used in this study, either by improving it or developing more precise and effective pre-tests, as an evaluation of the effect of the subtitles Second, by reviewing literature when using subtitled videos for language learning, it seems that there is still a gap in the knowledge, and areas that need to be explored with regard to using subtitled videos For example, the effectiveness of subtitled video has been explored extensively in terms of listening comprehension and vocabulary acquisition, but there is a lack of research in respect to the acquisition of lexical chunks 5.4 Implications for future research It can be said that subtitled authentic video, films and movies may be an optimal source of acquisition of lexical chunks for two reasons First, as authentic videos were not designed for learning purposes, they contain genuine use of language, in which phrases, collocations and lexical chunks form a large portion of the language used Second, in contexts where contact with native speakers is very limited, subtitled video becomes a valuable resource, offering easy and low-cost access to native speakers’ language, as used in daily life Thus, future research investigating the effect of exposure to subtitled authentic video on developing second language learners’ knowledge of lexical chunks would be a valuable study, informing both second language educators and learners 63 REFERENCES Alwehaibi, H., (2013) The Impact of using You Tube in EFL Classroom on Enhancing E Students' Content Learning In:The
