gratitude to my supervisor, Doctor Tran Thi Thanh Phuc, for her careful guidance, critical feedback, and enormous enthusiasm Without her support, this thesis cannot be completed I am grateful to all the lecturers of the Faculty of Post-graduate Studies, University of Languages and International Studies, Vietnam National University, Hanoi for their valuable teaching and assistance during my study at the college I would like to express my thanks to all my friends who were willing to help me in sharing materials and ideas when this thesis is worked on My sincere thanks also go to all my

process of writing this thesis ii ABSTRACT This study investigated the processing difficulty of relative clauses in two groups of Vietnamese students with high and low level of English proficiency It also aimed at exploring errors on relative clauses made by 11th form Vietnamese students at a high school in Hanoi 65 students from two classes were invited to join in the research They answered a test including 30 questions about different types of English relative clauses, namely, SS, SO, OS, and OO The results indicate that participants in both two groups faced more processing difficulty in OS and OO type than the others, providing weak evidence for any of the four hypotheses: SOHH (Subject-Object Hierarchy Hypothesis); NPAH (Noun Phrase Accessibility Hierarchy Hypothesis); PFH (Parallel Function Hypothesis; PDH (Perceptual Difficulty Hypothesis) Moreover, although students in the high proficiency group performed better than those in low proficiency group, they all made a number of mistakes in doing relative clause exercises iii TABLE OF CONTENTS DECLARATION i ACKNOWLEDGEMENTS ii ABSTRACT iii LIST OF ABBREVIATIONS vi LIST OF TABLES vii CHAPTER I: INTRODUCTION CHAPTER II:

important role Among different grammatical aspects, relative clauses have been showed to be a great obstacle for students This study aimed to explore the validity of different hypotheses on the acquisition of relative clauses among Vietnamese high school students 1.1 Rationale Nowadays, English has become a useful tool to get access to the world‟s knowledge and to achieve success in life To master English, students often focus on the learning of four major language skills, namely, listening, speaking, reading and writing However, grammar is the basis for the development of all these skills As a teacher of English, I realize that relative clauses (RCs) are one of the most difficult grammar aspects for students of English to master Many errors associated with relative clauses have been committed by my students, despite the fact that they have spent a significant length of time studying them For examples, a great number of students are confused about the forms and functions of the English relative clauses They often make mistakes in combining sentences containing relative clauses and fail to distinguish between restrictive and non- restrictive relatives Therefore, I would like to know and understand more about this issue Research on RCs has been conducted in a number of countries The majority of these studies focus on testing the validity of different hypotheses related to the acquisition of RCs For example, Alotaibi (2016) identifies that the most difficult type of RC for Kuwaiti EFL learners is OO (object-object), while Abdolmanafi and Rahmani (2012) points out that students encounter more difficulty in SO (subjectobject) In Vietnam, research following this approach has been quite limited One study by Lan (2009) does not focus on testing RC hypothesis, but aims to point out typical mistakes committed by Vietnamese students She identifies these as the wrong use of relativizers, the misuse of the relative clauses, and the misuse between restrictive and non-restrictive relatives such as teachers or salon Students are required to define the words by using relative clauses like This is a person who give lectures at school for teacher or this is a place where a hairdresser work for salon Therefore, relative clauses can be practiced and improved naturally through this game 5.2 Conclusion The study has contributed to understanding of the acquisition of English relative clauses in a high school in Vietnam through examining learners‟ comprehension and production tasks of RC The results showed that none of the four proposed hypotheses offer a reasonable account for the difficulty in their acquisition of English relative clauses It was identified that students made a number of errors such as the wrong use of relativizers, the misuse of the relative clauses, and the misuse of restrictive and non-restrictive relatives A comparison between two groups of students shows that high proficiency group students outperform those of low proficiency 5.3 Suggestion for further research Firstly, this study can be duplicated with a larger number of participants and more questions in the test This will help to arrive at more convincing conclusion for the research Secondly, it is suggested that future research can involve learners at various proficiency levels from different schools Finally, the scope or coverage of the relative clause type was limited to SS, SO, OO and OS Therefore, further study investigating more types of relative clauses, such as GEN, OPREP, and OCOMP are recommended 36 REFERENCES Alotaibi, A (2016)
