such as describing things, objects, or expressing feeling, emotion As well known, English adjectives are diversified in many forms, meanings as well as usages It takes learners quite a long time to understand adjectives deeply As a result, students of English often make errors when they use adjectives Therefore, this research work is focused on investigating common errors in the uses of adjectives Actually, the most important purpose is to show how to use the adjectives and to suggest some solutions to the problem Based on material analysis and error analysis, the types of errors and causes have been found Solutions to the problems have been suggested STATEMENT OF AUTHORSHIP Title: Common errors in the use of adjectives made by the students in grade eleven at Hoang Quoc Viet High

EXERCISES 40 INTRODUCTION I Rationale English is used as an international language in many countries all over the world In Vietnam as well as in other countries, there is a greater and greater need to learn English English is used in politics, business dealings, and everyday life No one can deny the importance of learning English in Vietnam at present Therefore, English is being taught at every educational level We know that, studying English nowadays has become an essential demand for everyone However, each language has its own origin, characteristics and values leading to Vietnamese learners have to face many difficulties when they learn this international language It is proved that English grammar is complex, so it often causes embarrassments to learners Adjective is one of the essential parts to form a sentence in English grammar that students have to learn too much at schools English adjectives are diversified in many forms, meanings as well as usages Therefore, using adjectives correctly and effectively is rather complex Though Vietnamese learners are trying to study English, the result does not come up to our expectation due to both subjective and objective causes Due to its various uses, it is assumed that there are many errors which may be made As a student in the Foreign Language Faculty, this thesis is accomplished with the hope of making a contribution to the process of teaching English especially in teaching adjectives for students in high schools For these reasons above, this study is conducted with the aim of focusing on error in using English among the students of English in grade 11 at Hoang Quoc Viet High school II Research presupposition Some questions are raised: What kinds of errors in the use of adjectives are made by the students in grade 11 at Hoang Quoc Viet? What are the causes of the errors in the use of adjectives by the students in grade 11 at Hoang Quoc Viet High School? What are the effective ways to minimize the errors made by the students in grade 11 at Hoang Quoc Viet High School? III Research objectives The study is aimed at the following goals: To find out the main errors in the use of adjectives made by the students in grade 11 at Hoang Quoc Viet High School To find out the causes of the errors in the use of adjectives by the students in grade 11 at Hoang Quoc Viet High School To offer some suggestions to minimize the errors made by the students in grade 11 at Hoang Quoc Viet High School IV Research scope The general research area of this study is grammar The phenomenon is focused on the errors in using adjectives made by the students in grade 11 at Hoang Quoc Viet High The population involved in the study is 92 students V Research tasks The study involves the following tasks: Studying the definition, formation, classification and meaning of adjectives in English Studying the grammatical features of adjectives in English Conducting a survey to find out error types and causes of the uses of adjectives in English Suggesting some solutions to minimize the students’ errors VI Research methods To achieve the objectives of the study, the following methods have been applied: Synthesizing theoretical materials on English grammar and linguistics Conducting test survey and analyzing the results Offering suggestions and solutions to the problems VII Research significance This study is hoped provide the following: Input for learners of English in order to have better understanding about adjectives in English, specially at high school level Input for learners in order to minimize their errors in using adjectives VIII Research design The research work has three main parts: Introduction, Development and Conclusion The part Development has two chapters Chapter one Theoretical Background consists of two sections Section one presents literature review in brief and section two deals with adjectives in English in definition, classification, position, usage, and order Chapter two is Common errors in the use of adjectives It describes the research method It is composed of three sections Section one is devoted to the survey The second deals with error types and causes The last one is solutions to the problems and suggested exercises on adjectives Hopefully, the students in general and the students at Hoang Quoc Viet High School in particular can minimize errors in the uses of adjectives II.3.2 Suggested exercises Exercises on the use of adjectives in grammar and test books could be made to consolidate what students have learnt Moreover, teachers are also advised to design particular exercise types to minimize students’ errors in the use of adjectives Here are some suggested exercises types Find and underline the adjectives in the given sentences Choose the correct form of words: adverb or adjective Choose the correct answer to complete each sentence Change the form of the words using suitable form of adjectives As for the first exercise type, the students have to find the adjectives in each sentence This exercise is designed to consolidate what students have learnt about adjectives in terms of positions, uses and the meaning It required students to understand the uses of adjectives The second exercise type is designed to help students to distinguish between the use of adjectives and adverb By doing this exercise, students can minimize error in the use of adverb instead of adjective The third exercise type is aimed at helping student master the order of adjectives By practicing this exercise, students can minimize the errors in ordering adjective As for the last exercise type, students have to distinguish between the use of adjectival participles ending in “-ed” and “-ing” It requires students to understand the use of adjectival participles ending in “-ed” and “-ing” Therefore, they can minimize errors To sum up, these exercises are hoped to improve students’ understanding of adjectives, and minimize their errors 36 PART THREE CONCLUSION Grammar plays a center role in the language system In other words, it is the foundation on which all learners have to base themselves to master a new language It is undeniable that adjective is one of the essential parts to form a sentence in English However, English adjectives are diversified in many forms, meanings as well as usages Therefore, students often face difficulties and make mistakes when dealing with them For this reason, the study has focused on errors in the uses of adjectives among the students in grade 11 at Hoang Quoc Viet High School The analysis has shown that most students cannot grasp all types of adjectives Many students admitted that they often feel confused in the uses of adjectival participles ending in “-ed” and “-ing” It is difficult for them to remember the order of adjectives The thesis gives an understandable picture of the adjectives such as definition, classification, positions and uses Hopefully, the students will have a full look at the adjectives Then a survey was conducted with the aim of testing the students’ understanding of the adjectives, and finding the common errors in the use of adjectives The survey was well prepared with the effort from the author as well as the consultancy from reliable sources of material Diversified exercises were included in the survey with the hope that the students would feel more interested in doing them The outcome of the survey has proved the eleventh-grade students at Hoang Quoc Viet High School often make mistakes in the use of adjectives The survey shows that the highest percentage of errors is in ordering adjectives, which account for 63.50% The second commonest are the errors in the placing adjectives before indefinite pronouns, which stand 62.15% The errors related to placing adjectives before adverbs are fewest, only 31.53 % From the result the survey, it can be seen that the major causes are students’ limited understanding of the adjectives That makes students confused in the uses of adjectives 37 Based on the analysis, the following notes are useful: To teachers: Lecture on the importance of adjectives Present the uses of adjectives with clear examples Provide students with sufficient knowledge of adjectives Introduce the ways and techniques to memorize and use adjectives Introduce adequate exercises related to adjectives To students: Be aware of the importance and usefulness of adjectives Grasp the theory of adjectives and their uses Do as many exercise related to adjectives as possible Read the instructions and analyze the sentences carefully when dealing with exercises Apply the rules when dealing with exercises It is hoped that study has made certain contributions to the English teaching and learning practice in Vietnam Although I have made efforts, mistakes and shortcomings are avoidable I would be much grateful to welcome all possible comments from readers to accomplish the work 38 REFERENCES Alexander, L.G (1988) Longman English Grammar New York: Longman Publishing Aik,
