 Education and training play an important role in the development process of the country. In the current period, the country is on the path of reform, opening-up policy relations with the countries of the world increased significantly. Extensive communication with the countries in the world in English , the international language , has become more more and common and attention.

 In teaching English I have noticed that practicing English pronunciation is the misery of our students, especially students in grade 6 whether they have been studying for 3 years at the elementary level, . and in the end they still do not get the standard English pronunciation. Is learning to pronounce so difficult that can not be learned? or inappropriate teaching methods? Is textbook structure irrational? or Don’t they know how to learn?

 According to the old textbook program, the students did not learn about pronunciation so their spelling good or bad depends on the teachers.They leant Enlish pronounciation without rules and methods. That is why after 7 or 10 years learning English, they still find difficulties in speaking and communicating even they can speak fluently, Others can’t understand what they are expressing beacause of the mistakes. Besides, the pilot program presents the vocabulary, the grammar items tobe leaned and practised through the skills and activities of the unit, it also focuses on pronunciation. Two or three sounds,which frequently appear in the unit are targeted and practised in isolation and in context of “ A closer look 1”.

To help students participate in the English pilot program and overcome this obstacle, I choose content " Improving grade 6 students’ combination vowel sounds of English pilot program at Tran Phu Secondary School".

PART I. INTRODUCTION
I. REASONS FOR CHOOSING THE TOPIC.
	 Education and training play an important role in the development process of the country. In the current period, the country is on the path of reform, opening-up policy relations with the countries of the world increased significantly. Extensive communication with the countries in the world in English , the international language , has become more more and common and attention.
	In teaching English I have noticed that practicing English pronunciation is the misery of our students, especially students in grade 6 whether they have been studying for 3 years at the elementary level, ... and in the end they still do not get the standard English pronunciation. Is learning to pronounce so difficult that can not be learned? or inappropriate teaching methods? Is textbook structure irrational? or Don’t they know how to learn? 
 According to the old textbook program, the students did not learn about pronunciation so their spelling good or bad depends on the teachers.They leant Enlish pronounciation without rules and methods. That is why after 7 or 10 years learning English, they still find difficulties in speaking and communicating even they can speak fluently, Others can’t understand what they are expressing beacause of the mistakes. Besides, the pilot program presents the vocabulary, the grammar items tobe leaned and practised through the skills and activities of the unit, it also focuses on pronunciation. Two or three sounds,which frequently appear in the unit are targeted and practised in isolation and in context of “ A closer look 1”.
To help students participate in the English pilot program and overcome this obstacle, I choose content " Improving grade 6 students’ combination vowel sounds of English pilot program at Tran Phu Secondary School".
II. AIMS AND REQUIREMENTS OF THE STUDY.
 1. Aims.
 In order to help students in grade 6 of pilot program at Tran Phu Secondary School, Nong Cong District, Thanh Hoa Province understand the sound system in English, especially combination vowel sounds ( diphthongs) are enrolled at the second semester in the textbook 6. Thereby, the students have aware of the importance of phonetics in learning English in general and in particular to communicate in English so they can understand what other people say and what they say that others can understand.
2. Requirements.
 To success in the study, the requirement for the topic is that the teacher has to help students know how to pronounce dipthongs /eә /; /iә /; / әu/; /ai/; /aʊ /; /ɔi/ and do exercises correctly. Teacher provides them with the best way to assist them how to pronounce these dipthongs correctly through the illusions and examples. Students have to attend regularly and obey their teacher's requirements.
III. SCOPES AND OBJECTIVES OF THE STUDY.
1. Scopes
 As far as we know, teaching how to pronounce and how to do phonetics exercises is a complicating and difficulf area specially 6 dipthongs /eә /; /iә /; / әu/; /ai/; /aʊ /; /ɔi/ with students in grade 6. There are a lot of things to mention but in this study I only focus on the following fields: 
- Giving definition and how to pronounce these dipthongs.
- Collect exercises containing these dipthongs to help students practise listening and speaking at home. 
- How to do exercises relating to these dipthongs.
2. Objectives.
 As I have said my study is aimed at improving my students' pronounciation of dipthongs and help tgem to solve some difficulties in doing phonetics exercises so my objectives if the study are: 
- Students in class 6B : 27 Studensts, and 6C: 25 students. Total: 52 students
School: Tran Phu secondary school.
- The combination vowel sounds system in the lessons of the second semester textbook 6 of the pilot program, including sounds:

II. PRACTICAL BASES OF THE STUDY.
1. Real states of the problem.
 For students in grade 6 at Tran Phu Secondary School, Nong Cong district, they have learned English pilot program for 3 years but their pronunciation still has many difficulties. The pronunciation of the children are forced, many students are not willing to speak for fear of making errors that always leads to false in reading, speaking and recognizing the sound of the words when making phonetic exercises. 
 Through the survey to identify exercises sound /əi/ and /aʊ/ ( English 6, page 60) 
Exercise: Listen and put the word in the correct column.
voice down around house boy toy noisy flower shout boil
Key:
/ əi /
/aʊ/

The above results inspired me to do something to help them improve this difficulty, or at least help them not to feel afraid, find it less difficult to learn pronounciation.
2. Solutions .
Through many years of teaching I see that:
Most of the students pronounced these sounds in the words inaccurately. They also confuses with monopthongs. They didn’t also do the phonetics exercises relating to these sounds effectively. Why?
The reasons are that these sounds are difficult sounds. They are similar to each other.
The students didn’t give their whole mind to learn these sounds. The time and the exercises for the students to practise are limited. 
Besides that many of us – the teachers of English didn’t attach special importance to teaching phonetics in general and these consonant sounds in particular. We didn’t also have a suitable method to teach these sounds. Some of us only read and asked their students to repeat when teaching these sounds so we didn’t achieve the good result as we expected. 
My solution to these is " Improving grade 6 students’ combination vowel sounds of English pilot program at Tran Phu Secondary School".
2.1.The steps of teaching these sounds.
These six dipthongs are taught in pairs in three unit 8,9 and 13 in English 6. 
To teach these pairs of dipthongs I often follow the foolowing steps:
- First, I divide board into 2 parts,I write two dipthongs on the board and pronounce them clearly twice.Ask students to listen and observe.
 - Second, I show the mouth diagram of the sounds and explain how to make these sounds.
- Third, I pronounce these sounds again and sak students to repeat.
- Next,I have students distinguish the sounds with the other dipthong or monopthong. Students listen and compare the differences between two dipthongs.
Example : Distinguish sound / i:/ and / iә/
/i:/
/ iә/
e /i:/
pea /pi:/
tea /ti:/
bead /bi:d/
ear / iә/
pier/ piә/
tear / tiә/
beard/ biәd/
Distinguish / eə/ and / iə/ sound.
/eə/
/ iə/
air
bear
chair
hair
ear
beer
cheer
here
- Then, I read the couples of words and ask students to repeat.
- After that I ask students to look at the sounds in some words and read them loudly
Example: Look at the /iә/ sound in some words.
ear /ɪər/
hear /hɪər/
really /ˈrɪəli/
cheerful /ˈtʃɪəfl/
career /kəˈrɪər/
- Finally, I give some sentences that contain these sounds, read and sak students to repeat.
Example : Listen / iә/ sound in some sentences.
- We're here.
/wɪər hɪər/
- Have a beer, cheer!
/ hæv ə bɪər tʃɪər/
- Is there a bank near here? 
/ɪz ðeər ə bæŋk nɪər hɪər/
- The meaning isn't really clear.
/ðə ˈmiːnɪŋ ˈɪznt ˈrɪəli klɪər/
2.2. Some experiences help students do phonetics exercises relating to the dipthongs /eә /; /iә /; / әu/; /ai/; /aʊ /;/ɔi/.
 There are some letters transcribed in two different sounds that make students confuse easily. For example "hear"/ hiә/ and hair / heә/. Some experiences help students do phonetics exercises relating to the dipthongs /eә /; /iә /; / әu/; /ai/; /aʊ /; /ɔi/ . So in this study I also give out some of my experiences when doing phonetics exercises – find out the word that has the underlined part pronounced differently from the others- relating to the sounds . I often teach this part in revisions or in extra-lessons because the time in class is not enough. In this part, I often give out some signals to help students do this kind of exercises better.
