ACKNOWLEDGEMENTS This study would not have been possible without the intellectual and emotional support of the many important people in my life First and foremost, I would like to thank my supervisor, Dr Nguyen Thanh Minh Without his assistance and dedicated involvement in every step throughout the process, this paper could have never been accomplished I am extremely grateful to him for supporting and understanding me during the past time My special thanks also go to all my lecturers at the Faculty of Foreign Languages, Hong Duc University, for their scientific knowledge through practical lectures, which is the premise They help me a lot in completing this study I would like to thank the teachers and students at Le Hoan High School, where I conducted the research experiment They helped me collect data, survey questions and experiment with learning and teaching Without their help this thesis would not have been so successful Last but not least, I also owe my indebtedness to my family members for their love, care and encouragement when I was in the process of writing this thesis I sincerely thank you! Thanh Hoa, May 20, 2022 Supervisor Student Nguyễn Thanh Minh Trần Thị Ngọc Minh i ABSTRACT This study is aimed at investigating how error correction is carried out in speaking classes for the 10th form students at Le Hoan High School and finding out suitable error-correction strategies The data were collected by means of class observation and questionnaire administered to teachers of English and 82 students The results show that the majority of the teachers themselves gave corrections to unselective errors, mostly grammatical and phonological errors, by means of explicit correction while the activity is in progress The study suggests that the teachers should have at their disposal a wide variety of errorcorrection measures to be able to deal more appropriately and effectively with student oral errors In addition, they should develop more positive attitudes toward oral errors and error correction For pedagogical implications for secondlanguage classrooms, error correction is of great use when an error is corrected in an method way ii LISTS OF ABBREVIATIONS AND TABLES Abbreviations CLT Communicative Language Teaching COFs Classroom Observation Forms CUP Cambridge University

Luan an Do an PART I: INTRODUCTION I Rationales In today's society, English is very important For many people, learning English is essential Teaching and learning revolve around developing four abilities, with speaking being the most difficult for students to master since it demands them to create words spontaneously or without enough time to compose suitable and proper utterances Errors and error correction have received much attention in speaking workshops throughout the years (Ellis, 1994) Various authors have distinct points of view Some people regard a error as a regular occurrence They say that humans can't help but make errors and that they may even learn from them Making errors is a natural part of learning, and correcting them wisely can help you achieve better results in the classroom On the other hand, others see an error as a negative that must be avoided As a result, language teachers have always had a negative attitude regarding it They generally have the most authority to automatically correct students' faults, even though students appreciate and expect teachers to correct them Correcting learners' vocal faults is one of the most challenging duties for most language teachers since it involves greater subjectivity owing to individual factors (Cohen, 1998) Error correction is complex and perhaps baffling when individual elements are considered crucial aspects in speech As a result, errors correction must be done correctly, lest learners become discouraged from learning and practicing the language Although error correction has been a subject of research for a long time, many linguists have focused mainly on the sources of errors, whether or not to correct spoken errors, and error correction approaches However, there is limited study on effective error-correction procedures in general and in speaking classes The issue above of error correction in speaking classes, as well as the information vacuum in the research domain, piqued my attention and prompted Stt.010.Mssv.BKD002ac.email.ninhd

place in Le Hoan High School The study's primary goal is to discover effective error-correction procedures in speaking classes To be more explicit, the purposes of this thesis are to: + to examine how teachers correct their students' oral faults + to identify acceptable error-correction strategies in speaking classes + to make suggestions for repairing oral problems in speaking classes III Scope of the Study Students' language, whether spoken or written, is deemed productive Errors can happen in both speaking and writing classes Due to time, ability, and data availability constraints, we wish to analyze the current situation of errors correction at Le Hoan High School's speaking classes and identify acceptable error-correction procedures for use in a real-world setting Because the participants in this study were limited to students in the 10th form at Le Hoan High School, their views on appropriate error-correction strategies in speaking classes may not represent all students at Le Hoan High School in particular, or all students are learning English in general IV Research Questions The following research questions are addressed to attain the study's objectives: What kind of oral blunders students frequently make in speaking classes? When and how are oral errors in the classroom corrected? What are the best ways for correcting errors in speaking classes? V Methods of the Study We study the associated materials to meet the study's objectives, which is a technique of establishing the study's theoretical basis The study employs both qualitative and quantitative methodologies Survey questionnaires and classroom observation are used to collect data for study analysis and debate The data Stt.010.Mssv.BKD002ac.email.ninhd

classroom observation forms are analyzed using a quantitative manner (COFs) We then synthesize and analyze the COFs Relevant information to support the study will be obtained by employing each strategy VI Significance of the Study Errors by students are essential in both English as a foreign language (EFL) teaching and learning since they constitute indicators of their learning progress As a result, this thesis will provide a novel contribution to second language acquisition (SLA), specifically in the area of error correction in speaking classes Pedagogically, the findings of this study may assist English teachers in better understanding spoken faults and how to remedy them They change their teaching and use suitable error-correction tactics as a result of this to improve error-correction effectiveness As a final-year linguistics student, the researcher will have a thorough understanding of the process of teaching and learning EFL in general and errors and error correction in speaking classes in particular These will aid in improving instructional efficiency VII Structure of the Study The research is divided into three sections: Part I, Introduction, the motivation, goals, scope, research questions, research methods, importance, and organization of the study are all included in this section Part II, Development, is divided into four chapters: Chapter 1, Literature Review, discusses many topics related to the research issue, such as teaching and learning methods to speaking The overview of errors that follows goes through the definitions of errors as well as the many sorts of errors This chapter also contains perspectives on acceptable errorcorrection tactics, including when, what, who, and how to effectively correct errors

learning occurs The teacher's attitude toward errors will have good consequences on pupils, the most significant of which will improve their confidence and help them overcome their fear of making errors Third, correcting errors is a good idea Teachers' perspectives on error correction are thought to impact their actions Hence teachers should be encouraged to learn about and develop insights into the subject Correcting a student's speech faults should be done to promote learning and enlist the participation of other pupils Teachers choose the language to use for converting depending on the circumstances to establish learning-friendly settings Finally, a thorough grasp of the nature of errors is required before a systematic approach to eliminating them can be devised As a result, teachers should be aware of the error system Only when teachers understand why a error occurred can they begin to repair it in an organized and suitable manner Limitations of the Study There are various limitations to this study that should be mentioned in this debate For starters, external dependability is jeopardized since the teacher's and researcher's joint roles may cause data analysis to deviate The teacher may have his expectations about the study's findings Nunan (1992) wonders if an independent researcher could replicate the research and develop the same results Second, more systematic and extensive studies are required, considering various levels of explicit and implicit correction The current study only looked at two types of punishment: explicit and implicit The focus on possibilities may be expanded to incorporate various levels of implicitness and explicitness encountered in classroom contexts Third, problems such as time, manner, and kind of correction are so vast and complicated that short research like this cannot adequately explain them Furthermore, further in-depth research might be conducted to determine which Stt.010.Mssv.BKD002ac.email.ninhd

and preferences The result may be more rewarding for the students if the teacher pays close attention to students' variations and employs a variety of corrective tactics based on their requirements,
