INTRODUCTION
1. Motivation of the study
Nowadays, the tendency of globalization has raised the important role of English
spectacularly. As a result, more and more people learn English as an international
communicative tool. In Vietnam, English has become an obligatory subject in
schools for many years. Vietnamese students study not only four language skills:
Listening, speaking, reading and writing but also language focuses including
grammar, vocabulary and pronunciation simultaneously in English courses.
However, they find difficult in communicating with native speakers and non-native
speakers as well and many foreigners have made comments that a large number
Vietnamese can speak English, yet a few have intelligible English pronunciation
which help them be understood easily by foreigners. In domain of international
communication, English speaking skill need to be proficient. The core of speaking
is producing sound and meaning intentionally. Mastering pronunciation is the
priority of speaking because “up to a in certain proficiency standard, the fault which
most severely Impairs the communication process in EFL/ESL learners is
pronunciation, rather than vocabulary or grammar, according to Hinofitis and Baily(
1980, pp.124-125).
Vietnamese students in High Schools learn pronunciation at language focus lessons.
In comparison to grammar and vocabulary, it is usually not paid much attention. In
forty-five minute classroom hour, it takes about from five to ten minutes for the
teachers to instruct the focused sounds and help their students practice them because
they need more time to study grammar. In a very short time, the teachers only can
guide the students to pronounce the noticed sounds in words and sentences by
modeling and repeating them, they don’t have enough time to instruct how
articulation the sounds employ and what articulators the sounds use and the learnt
sounds are rarely compared with similar Vietnamese sounds. The students mostly
listen to the teachers’ model, sometimes native speakers’ tape recording; however,
many teachers are not very proficient at pronunciation which leads to wrong input
2
language. As a consequence, the students gradually find hard to take in real English
and perform correct pronunciation.
In term of language transfer, many learners use their mother tongue to help them
create their language system. Hardly can the students tell differences between
English texts and English sounds. They don’t know what sounds represent for what
letters and vice versa because they spend much time on English texts, using their
eyes to adsorb English not their ears. In process of learning pronunciation, English
sound need to be both the ears and the mouths work together and their brain helping
them remember the sounds. Many students borrow Vietnamese texts, as a mean of
storing English pronunciation in their book or note book, to correspondence to
English sound. How their ears and their brains perceive the English sounds is much
more important.
In real contexts, the students love to use most common used words. Thanking
people and replying to thanks, as a vivid example; when someone give them a hand
or receiving compliments, wishes of success, an offer of help, an invitation, they
usually respond as “thanks”, “thank you”. This seems to be simple and easy when
they use the word “thank’’. However, there are a dozen of both sad and happy
situations occurring when “thank” is performed. They often mispronounce “thank”
as “tank” or “sank” or “thanh” of Vietnamese. Imagining that how funny and
embarrassed they are when they say “sank you, my mother”. Pronouncing “mother”
is also a dizzy problem, replacing “mother” as “murder” for example. “Thank you,
my mother” become “Sank you, my murder” which is a horrible respond when their
mothers give praises on them. Speaking words such as “father and brother”, as
another example, are usually not performed beautifully by many students. The
problematic sounds which they are dealing with are /θ/ as in “thank” and /ð/ as in
“mother”, which can create many obstacles in both formal and informal
communication.

Located at Tan Binh commune, Thanh Binh district, Dong Thap province, Thanh
Binh 2 high school is my old warmhearted school. As a future teacher, helping my
future students learn pronunciation well is my ambition. The fricatives /θ/ and /ð/
are really hard sounds which many students cream at, students at Thanh Binh 2 are
not an exception. Introduced at Unit 15 of English 10, the fricatives /θ/ and /ð/ need
to be paid more attention because they are first taught at high school. They will
learn consonant clusters containing fricatives /θ/ and /ð/ next grades. If they are not
guided carefully, many students will suffer from disaster’s /θ/ and /ð/ pronunciation.
“A good beginning makes a good ending”. Indeed, supporting the students at my
old school to get over the problems of pronouncing the two sounds is very
meaningful to me.
Because of these above reasons, I decided to do research on Thanh Binh High
School grade 10th
students’ difficulties in learning two fricatives /θ/ and /ð/,
teachers’ obstacles of teaching the two sounds, entitled: “An investigation into the
pronunciation of the fricatives /θ/ and /ð/ experienced by the students of grade 10th
at Thanh Binh 2 high school – problems and solutions”. The study was conducted to
seek the answers to the question of what difficulties the students and teachers of
grade 10th
at Thanh Binh 2 high school face when they learn and teach the fricatives
/θ/ and /ð/ pronunciation, what phonemes which the replace /θ/ and /ð/ with, what
solutions to the difficulties for both the students and the teachers.
2. Aims of the study
With the mentioned reasons, this study was conducted to gain some following
aims:
-Finding out realities of learning and teaching dental fricative /θ/ and /ð/ at Thanh
Binh 2 high school.
-Discovering what English sounds and Vietnamese sounds, which the students
replace /θ/ and /ð/ with.
-Making some suggestions for both teachers and students to overcome the
difficulties.
4
3. Theory of the study
This study was conducted based on two following theories
- The students have difficulties in distinguishing /θ/ and /ð/ with other English
fricatives and plosives when listening to them in context.
- The students have substituted /θ/ and /ð/ for Vietnamese sounds: /t’/, /d*/ and
/s*/.
4. Research methods
In the process of doing the study, three research methods: classroom observation,
questionnaire, and experiment, were used to secure relevant information. First,
listening experiment was carried out. Then pre recording experiment was
conducted. Next, classroom observations were employed. Coming after that, the
students’ questionnaires delivered. After that, the researcher carried out teaching
experiments. Finally, post-recording experiment was put in action.
5. Scope of the study
The thesis focuses on research learning and teaching /θ/ and /ð/ pronunciation of
students’ grade 10th
and teachers at Thanh Binh 2 High School. Because I have
practiced teaching four classes 10cb1, 10cb2, 10cb3, 10cb4 in my teaching practice
period, my study was only researched on the four classes.
6. Significance of the study
The study, the researcher’s ambition on doing educational scientific research, has
paid the researcher many experiences than before, has contributed certain benefits
for learning and teaching pronunciation. It is a chance for the researcher to do
scientific research, to practice writing skill, to enhance his social skills as well.
Because the thesis focused researching θ/ and /ð/, it helped the researcher
experiment his own methods of teaching /θ/ and /ð/. Consequently, the researcher
could seek good solutions for both teachers and learners when teaching and
5
learning these challenging phonemes. Furthermore, the thesis is about to wake the
students up to see how crucial pronunciation is, and how interesting pronouncing
correctly /θ/ and /ð/ is. Many students will take pride on themselves when they can
pronounce /θ/ of a famous interjection “thank you” correctly, even more, can
speak /ð/ of wonderful words like “mother, father” wonderfully. In addition, it also
highlights difficulties of pronunciation /θ/ and /ð/. Accordingly, teachers will pay
more attention to these hard phonemes. In brief, the study brought advantages for
the researcher, teachers and students.
7. Related previous study
-The effectiveness of using game in teaching and learning pronunciation for grade
11 students at Sa Dec town high school by Do Nguyen Xuan Thao,
-Improving the pronunciation of English final sounds / k/, t ʃ/. / ʃ/,/θ/ and /dʒ/ for
the second- year students of bachelor of English at Dong Thap University by
Nguyen Thi Truc Giang.
Although the two studies have contributed to improving the students’
pronunciation, they are weak at methodologies of study, giving recommendations.
When analyzing the learners’ error pronunciation, Nguyen Thi Truc Giang just
used qualitative methods not quantitative ones. Also, Do Nguyen Xuan Thao did
not make clear pronunciation difficulties of the learners. They didn’t also focus on
researching /θ/ and /ð/.
8. Organization of the thesis
The present study comprises three parts. The first one is the introduction bearing
motivation of the study, aims of the study, scope of the study, the theory of the
study, research methods, and significance of the study, related previous studies,
and organization of the study. The second one is the content of the study which
includes three chapters. Chapter 1 is concerned about literature review, chapter 2
the methodology of the study, and chapter 3 the results and discussion. The last one
6
is the conclusion of the study consisting of overview of the study, limitations of the
study, and suggestions for further research.
CHAPTER 1 LITERATURE REVIEW
This chapter presents some theories related to the study. It is made up of six
sections: introduction of pronunciation in general; introduction to English fricatives;
a brief introduction to Vietnamese consonants; comparison between /θ/, /ð/ and /t’ /,
/d*/, /s*/ of Vietnamese; factors influencing on studying pronunciation;
pronunciation teaching methodologies.
1.1 Pronunciation
1.1.1 Definition of pronunciation
Learning to speak a foreign language, English as an example, means dealing with a
new way of producing a wide range of new sounds. In term of both native and
nonnative speakers’ perception, it takes time to practice and produce them
comprehensibly. Producing sounds of speech with certain meanings refers to
pronunciation. Encarta Dictionary defines pronunciation as “the way in which a
sound, word, or language is articulated, especially in conforming to an accepted
standard’’. Another explanation, “Pronunciation is the act of uttering with
articulation; the act of giving the proper sound and accent; utterance; as the
pronunciation of syllables of words; distinct or indistinct pronunciation”, adapted
from Lac Viet dictionary can be more detail .Far beyond the spoken individual
sounds, pronunciation also conveys the soul of the language such as intonation,
stress words, rhythm and speakers’ unique voice quality. Because of varieties of
English, people can pursuit different English accents which they like. A model of
English pronunciation was used mostly is BBC English (British English); however
American English pronunciation is also popular. What models of English
Pronunciation can be used by the learners; comprehension by both native and non-
7
native speakers is the ambitious goal of most of them.
1.1.2 The important role of pronunciation
Language is a magic communicating tool. People can communicate through spoken
language or written one as well. It is oral communication that people typically use
in not only daily life but also academic cases. Thus, pronunciation plays an
important role of communication. Clear and confident speech can enhance what we
speak even polish our unique characteristics. Kenworthy(1987, p34) stated that
“poor, unintelligible speech will make their attempts at conversing frustrating and
unpleasant both for themselves and for their listeners.”, so the goal of English
pronunciation is to be understood, to be proud of the ways we pronounce English.
Furthermore, good pronunciation can create many interests on listeners in
communication. When the listeners can taste the beauties of the speakers’ spoken
language through their ways of producing English sounds, they can comment that
“you have good English” or “you speak English so well”. What they primarily react
to the speakers is usually their pronunciation. Also, good pronunciation, sub-skill of
speaking skill, can be magic communicating attraction. As an example, in tourism,
both native and non native visitors would rather spend hours on listening to easily-
comprehended spoken English of a tour guide than try to listen deadly choppy and
incomprehensible of a manager in just thirty seconds since they are fell
comfortable and respectful. Therefore, good spoken English often creates much
attractive to listeners, regardless of whom the speakers are.
Pronunciation also plays an important role of both perceptive and productive
language skills. For the most part, speaking skill is the ability to produce the
comprehensible sounds. When learners have good spoken English, they easily
understand others and vise versa. No matter how good grammar and vocabulary the
speakers employ, they can be incomprehensible speaker when they earn much
pidgin pronunciation. In the process of speech, speaking and listening skill work
8
together at the same time. Listening skill is very crucial if the listeners want to
respond the speakers appropriately. Both listeners and speakers can understand
together when their spoken language at a same interchangeable language rate. In
term of bottom up listening, people need to have ability to decode spoken language
based on their phonetic ability. As a sequence, perfect pronunciation is convenient
for both listeners and speakers.
In short, pronunciation is very essential for learners in both foreign communication
and language skill improvement. The better pronunciation they gain the better
speakers they are. When their pronunciation is more proficient, their
communication will be more effective, their listening skills and speaking ones are
good as well.
1.2 The brief introduction to English fricative consonants
Roach, P (1999, p34) defined “fricatives are consonants with characteristics that,
when they are produced, air escapes through a small passage and makes a hissing
sound”. Another explanation by Kennedy, G (2000, p123), “the airflow can be
made turbulent in friction, thus producing fricative consonants”, can be clearer.
Nine fricatives /f/, /v/, /θ/, /ð/, /s/, /z/, /ʃ/, /ʒ/, /h/ are described with terms of place
of articulation, manner of articulation, and degree of noise in the following table
below

In English, combination of two letters t and h is very popular in English. They stand
for one of two different sounds:
-The voiced dental fricative /ð/
-The voiceless dental fricative /θ/
The popularity of /θ/ and /ð/ is shown in the below table, according to Kennedy, G
(2000, p 100).

1.2.1.1 The features and mispronunciation of /θ/
*Place and manner of /θ/ pronunciation
12
The /θ/ sound has been described in term of place of articulation and manner of
articulation, degree of noise, adapted from http://www.learning-english-
online.net/areas/pronunciation/the-english-th/
-Its manner of articulation is fricative. That means the sound is produced by letting
air flow through a narrow channel at the place of articulation. In comparison to the
voiced /ð/, the /θ/ is pronounced by making more air flow.
-Its place of articulation is dental. However, in contrast to /ð/, the sound is
pronounced with the blade of the tongue resting against the lower part of the back
of the upper teeth. The tip of the tongue sticks out of the mouth slightly.
-Its phonation (degree of noise) is voiceless. That means the sound is produced
without vibrations of the vocal cords.
It can be more visual when the /θ/ is described by the picture below, according
Jonathan Marks (pp 38)
Picture 1.2.1.1a Place and manner of articulation of /θ/
When spoken /θ/ is analyzed by speech analyzer program, the sound is much more
graphic.
Picture 1.2.1.1b Waveform and frequency of /θ/
13
**Mispronunciation of /θ/
Many learners have replaced /θ/ with /s/, /t/ because they don’t know how their
articulators work when pronouncing /θ/. Most of the learners have difficult in /θ/ at
beginning and final positions. They tend to substitute /θ/ with /t/ at the beginning
position and /s/ at the ending positions. These pictures, as an example, according to
Lisa Mojsin, (pp44-47) give a comparison /θ/ with /s/, /t/ can be make clear their
problems.
Picture 1.2.1.1c A comparison between /θ/ and /t/ in term of place of articulation
14
The picture shows that /θ/ employs dental articulator (inter-dental) to make the
sound but /t/ earns alveolar one. In addition, /t/ is plosive while /θ is a fricative.
Picture 1.2.1.1d A comparison between /θ/ and /s/ in term of place of articulation
The picture also illustrates that /θ/ is different from /s/ in term of place of
articulation. The /θ/ is pronounced at inter-dental position, but /s/ is pronounced at
alveolar position though the two sounds are fricatives.
15
1.2.1.2 The features and mispronunciation of /ð/
*Place and manner of /ð/ pronunciation
The sound /ð/ has the following features described by http://www.learning-english-
online.net/areas/pronunciation/the-english-th/
-Its manner of articulation is fricative. That means the sound is produced by letting
air flow through a narrow channel at the place of articulation.
-Its place of articulation is dental. That means the sound is articulated with the tip
of the tongue against the back of the upper teeth.
-Its phonation (degree of noise) is voiced. That means the vocal cords vibrate
during the articulation.
It can be more visual when the /ð/ is described by the picture below, according
Jonathan Marks (2000, pp 38)
Picture 1.2.1.2a Place and manner of articulation of /ð/
When spoken /ð/ is analyzed by speech analyzer program, the sound is much
more graphic.
Picture 1.2.1.2.b Waveform and frequency of /ð/
16
**Mispronunciation of /ð/
Majority of learners have replaced /ð/ with /d/ because they don’t know how their
places of articulation work when pronouncing /ð/, and they can hear /ð/ be similar
with /d/. Most of the learners have difficult in /ð/ at all positions, especially the final
position. They usually omit /ð/ at the final position. Furthermore, they tend to
substitute /ð/ with /d/ at the initial position, medial one. Even worse, the final /ð/
position is often omitted. The picture, as an example, according to Lisa Mojsin,
(pp44-47) gives a comparison /ð/ with /d/ can state more explicitly their difficulties.
Picture 1.2.1.2c A comparison between /ð/ and /d/ in term of place of articulation
17
The picture demonstrates the differences from place of articulation of /ð/ and /d/.
The voiced /ð/ is pronounced with tongue placed at inter-dental position whereas
the voiced /d/ is pronounced with tongue placed at alveolar one.
1.3 The brief introduction to Vietnamese consonants
Thien Thuat, D stated that Vietnamese owns 30 consonants, including 22 initial
consonants and 8 final ones. Vietnamese do not have any medial consonants .The
consonants are shown in two tables below

1.3.1 Pronunciation features of /t’ /, /d*/, /s*/ of Vietnamese
1.3.1.1 The features of / t’ / pronunciation
Based on table 1.3a Initial Vietnamese consonants, /t’/ is the voiceless aspirated
flat laminal (alveolar or apico-dental) plosive consonant; it is produced with a
strong aspiration. And phoneme /t’/ is an initial consonant, In Vietnamese, the
combination between letter t and h is ‘th’ corresponded to /t’/, ex: thi: ‘to take an
exam’; thơ : ‘poetry’; thắng : ‘to win’.
1.3.1.2 The features of /d*/ pronunciation
Table 1.3a Initial Vietnamese consonants shows that the phoneme /d*/ is the
obstruent, voiced unaspirated, flat laminal (alveolar) plosive consonant. Phoneme
/d*/ is also an initial consonant. In Vietnamese, the letter “đ” is stood for /d*/, Ex:
đi: ‘to go’; đầu : ‘head’; điếc : ‘dead’.
1.3.1.3 The features of /s*/, /ʂ/ pronunciation
Table 1.3a Initial Vietnamese consonants demonstrates the two similar fricatives
- /s*/ is the voiceless flat laminal (post-dental sibilant) fricative. In Vietnamese the
letter “x” is corresponded phoneme /s*/ E.g.: xé (to tear); xấu (ugly); xin (to ask
for).
-/ ʂ / is a voiceless fricative articulated like the English /s*/ with laminal retro-
flexion of the top of the tongue back further behind the alveolar ridge with weak
friction; In Vietnamese, the letter ‘s’ stands for /ʂ/. E.g.: số (number); sai (wrong);
sướng (happy).
In reality, many southern Vietnamese cannot distinguish /s/ and /ʂ/, so the two
phonemes can be considered the same. They are simply described as voiceless
laminal fricatives. In order to do conduct the thesis easily, the researcher
intentionally equalized /s*/ and /ʂ/ as /s*/.
20
1.4 The comparison between /θ/, /ð/ and /t’ /, /d*/and /s*/ of Vietnamese
The table 1.4 A comparison between /θ/, /ð/ and /t’ /, /d*/ and /s*/ of Vietnamese
The table concerns some basic pronunciation features of English /θ/ and /ð/ and
Vietnamese /t’/ and /d*/, /s*/. From the table, the phoneme /θ/, /ð/ and Vietnamese
/s*/ are fricatives. When /θ/ is pronounced, it makes hissing sound and /s*/ also
shares the same characteristics. However, /θ/, /ð/ employ dental articulator, /s*/
earns laminal blade of tongue. In addition, the /θ/, /ð/ are inter-dental fricatives
whereas /t’/, /d*/ are alveolar plosives. Vietnamese students often confuse /θ/ and
/t’/ because they have the same represented letter ‘th’. They also hardly distinguish
/ð/ and /d*/ as well. The Vietnamese phonemes: /t’/, /d*/, /s*/ are just appeared at
the initial positions in words while /θ/, /ð/ are found at all positions.
1.5 Factors influencing on studying pronunciation
1.5.1 Native language
The mother tongue is the most influential factor effecting learners’ pronunciation.
Because learners are familiar with their own spoken languages, they easily fall back
on their languages to pronounce English. Accordingly, their spoken English have
distinct characteristics of their mother tongues. Vietnamese speakers, as an
example, who have unpronounced final consonants in their language, enviably meet
difficulty in pronouncing final English sounds, commented by Hammer (1991,
English /θ/ and /ð/ Vietnamese /t’ / and /d*/, /s*/

pp183). It is true that the more different sound systems of their languages from
English are, the more difficult they can acquire English pronunciation.
1.5.2 Age
Age deserves to be a concerning factor. According to Kenworthy, age is not the
crucial only factor that affects learning or improving pronunciation abilities of
learners. As many linguistic experts believed that adults acquire English
pronunciation slower than young children. And they usually have foreign accent
while the children often achieve native-like pronunciation. As Krashen (1988; p43)
stated that acquirers who begin to exposure to a second language during childhood
generally achieve higher second language proficiency than those beginning as
adults. However, this does not mean that no adults can achieve native-like
pronunciation. Brown (1992) represented that adults will be able to learn second
language phonology as well as children do, in a direct way, using a traditional listen
and repeat exercises, minimal pairs in the context of the sentences, conversation and
role playing. In short, both young learners and adults can achieve good
pronunciation.
1.5.3 English exposure
The more time English learners can interact with spoken English, the more
determiner of acquisition of good pronunciation they gain. It is very advantageous
to live in an English speaking country in a period of time. When listening to real
English and receiving feedbacks on their pronunciation, they can improve their own
English sound systems. Gradually, they can perform English successfully.
However, not everyone who learns English can luckily live in a real spoken English
country. As compensation, they fulfill their English environment by listening to
native speakers more often. A practical way making up English shortage is listening
to English, chatting with English speakers on internet, as an example. In brief, the
learners can improve their pronunciation if they spend more time on interchanging
spoken English.
22
1.5.4 Phonetic ability
The learners’ phonetic ability pays more success on acquisition of good
pronunciation. Kenworthy (1987) presented that every human being has ability to
imitate sounds, but some people are capable of seeing the difference between them
than other people, which means that they own good phonetic ability than other.
Therefore, they can imitate spoken English more accurately. More interesting, many
learners can speak like famous English speakers, Bill Clinton, as an example. In
short, everyone has phonetic ability but various.
1.6 Pronunciation teaching methodologies
Language teaching methodology has developed dramatically. English now is taught
mainly through communicative approaches. Consequently, many teachers of
English have paid more attention to spoken English not written one and learners
need to spend more time on listening and speaking English than before. In old
grammar translation method, the learners can be considered as deaf and mute
English learners. In matter of English speaking, they were not able to pronounce
English correctly. If the teachers want their students perform good spoken English,
their teaching pronunciation methodology needs more consideration.
Having good teaching pronunciation methodology, the teachers initially need to
perfect their important roles of teaching pronunciation. The most crucial role of the
teachers is to help their learners perceive the sounds because “learners will have
strong tendency to hear the sounds of English in terms of the sounds of their native
language”, according to Joanne Kenworthy (1987, p1). Since the teacher is the
magic powerful controllers in class, they help the learners with enormous things
such as helping those making sounds by explaining the sounds or giving some hints,
providing feedbacks on their pronunciation, pointing out what is going on,
establishing priorities, devising activities, assessing progress. When the teachers can
manage these stuffs successfully, they will be able to help their students a lot.
No matter what methods and approaches the teachers use to teach English
23
pronunciation, they aim that their students can produce intelligible pronunciation,
which means that their students can speak comprehensible English at a given time
in a given situations. As a sequence, the keys of pronunciation teaching is that the
teachers have to be smart to decide when to teach pronunciation, what
pronunciation techniques they employ, what models of pronunciation they follow.
In short, teaching pronunciation is hard task. And teachers are the crucial factor
helping the learners to learn pronunciation. Methodologies of teaching
pronunciation are important but how the teachers use them, which is much more
important.
CHAPTER 2 METHODOLOGY
This chapter provides the general description of how the study has been conducted.
The chapter comprises five sections: research questions, research participants, data
collection instruments, research procedure, and techniques of data analysis.
2.1 Research questions
The study makes great efforts to seek the answers to the three following questions:
(1)What problems can the students and teachers at Thanh Binh 2 high school face
when learning and teaching /θ/ and /ð/?
(2)What phonemes the students replaced /θ/ and /ð/ with?
(3)What solutions to the problems for both teachers and the students?
2.2 Research participants
2.2.1 The researcher
The researcher is Nguyen Van Sang Em, a fourth year student of English
DHSANH08A Class, at Foreign Language Department, Dong Thap University.
2.2.2 The participants of the study
2.2.2.1 The students
24
There are 427 students (320males and 107 females) in Thanh Binh 2 High School.
The teachers all commented that most of the grade 10th
students were not good at
English, particularly at speaking. In fact, there were only 2.35% of the students
getting over 5 marks in English in the school’s entrance exam. This is shown in the
figure below.
Figure 2.2.2.1 The students’ scores of English in the entrance exam in 2011
2.2.2.2 The teacher
There are five teachers of English, who are teaching English 10 at Thanh Binh 2
High School. Two are male, and three female. Their teaching experience ranges
from 2 to 10 years. In general, they are experienced teachers. The five all teachers
are researched.
2.3 Data collect instrument
In the process of doing the study, three research methods: classroom observation,
questionnaire, and experiment, which were used to secure relevant information.
First, listening experiment was carried out to check how well the students perceive
/θ/, /ð/ and distinguish them with other English sounds. Then, pre recording
experiment was carried out to check how well the students can pronounce /θ/, /ð/, to
find out what English sounds and Vietnamese ones they students replace /θ/, /ð/,
with. Next, classroom observations were employed to examine the realities of

teaching and learning /θ/, /ð/. Following that teachers’ questionnaires were
delivered to check realities of teaching /θ/, /ð/, to analyze the textbook the textbook
as well. Coming after that, the students’ questionnaires delivered to check realities
of learning /θ/, /ð/. After that, the researcher performed teaching experiments on
unit 14, lesson E language focus lesson focusing teaching /θ/, /ð/. Finally, post-
recording experiment was carried out to check how proficient the students
pronounce /θ/, /ð/, to compare the students’ proficiency of the classes taught by the
teachers and of the classes taught by the researcher.
2.3.1 The questionnaire
Questionnaires are believed to help researchers save a lot of time since “They are
self-administered and can be given to large groups at the same time” (Salinger &
Elena, 1989). The information can be obtained easily without the researcher’s
presence. Moreover, respondents including teachers and students may feel free to
answer the questions since their anonymity is assured. Because of the above
reasons, the questionnaires were employed in the study.
2.3.1.1 The questionnaire for teachers
The questionnaire (see appendix 2) consisting 22 items was designed for five
teachers of English. The aims of the questionnaire are described as follows:
Items 1, 2 are to find out the teachers’ attitudes towards the teaching pronunciation.
Item 3 is to find out how much time which the teachers use to teach fricatives /θ/
and /ð/ of language focus lesson.
Item 4, 5 are to discover teachers’ opinion about teaching /θ/ and /ð/ in language
focus lesson.
Item 6, 7, 8 are to investigate teachers’ opinions about bettering textbook.
Item 9, 10, 11 are to figure out the teachers’ combination with other lessons to teach
/θ/ and /ð/.
Item 13, 14, 15, 16, 17, 18, 19, 20, 21 are to investigate the teachers’ hints of
teaching /θ/ and /ð/.
26
Item 22 is to survey what pronunciation activities the teachers often used to teach
/θ/ and /ð/.
2.3.1.1 The questionnaire for students
The other questionnaire (see appendix 1) consisting 17 items was designed for
students. To preventing students’ difficulties from misunderstanding the questions,
the students’ questionnaire translated in Vietnamese (see appendix 7). The
questionnaire was handed out to 140 students (82 female, 60 male) of four classes:
10cb1, 10cb2, 10cb3, 10cb4 and only 140 questionnaires were collected. The
questionnaire investigates students’ attitude to English learning in general, English
pronunciation, and realities of students’ study /θ/ and /ð/pronunciation. The aims of
the questionnaire are described as follows:
Item 1, 2, 3 are to investigate the students’ attitude to English learning and English
pronunciation.
Item 4 is to survey the students’ psychology to learning pronunciation with their
teachers.
Item 5 is to investigate the students’ ways of learning English pronunciation.
Item 6, 7, 8, 9, 10, 11, 12 are to investigate realities of English environment to
students.
Item 13 is to survey the students’ interests in lessons teaching /θ/ and
/ð/pronunciation.
Item 14 are to find out what the students take note in lessons teaching /θ/ and
/ð/pronunciation.
Item 15 is to investigate students’ use of IPA to transcribe /θ/ and /ð/ pronunciation.
Item 16, 17 are to discover realities of describing θ/ and /ð/.
2.3.2 The classroom observation
Classroom observation is believed to provide researchers with rich and authentic
data. The purposes of observations are to crosscheck data from the future
questionnaires as well as investigate how pronunciation activities, warm up
activities are applied and how they affect on students’ /θ/ and /ð/ pronunciation. To
27
prevent teachers and students from preparing themselves, the exact objectives of the
observation was not informed to them in advance.
Four forty- five minute classroom hour observations were conducted on language
focus lessons taught by the two different teachers of English 10. Unfortunately, unit
15 Cities teaching /θ/ and /ð/ of English 10 was removed to lighten the course, so
the researcher suggested these teachers taught /θ/ and /ð/ in unit 12 Film and
Cinema, unit 14 The World Cup. In order to observe simply, observation sheets
were designed to record the information (see appendix6).
2.3.3 The experiment
It is believed experimental methods are very helpful ways to evaluate the study if it
is successful. In the process of doing the study, three experiments: listening
experiment, teaching experiment, recording experiments, were carried out.
2.3.3.1 Listening experiment
Many linguistics experts believed that the input language is very important to
acquire good pronunciation. As Stephen Krashen (1992.p234) asserted that
comprehensible input is all that is necessary for second language acquisition.
Spoken English is the most crucial factor effecting the students’ pronunciation.
The listening experiment was employed to check the students’ ability of perceiving
/θ/ and /ð/ and distinguishing with other English consonants. The listening
experiment checks the students’ distinguishing /θ/ with /s/; /θ/ with /t/ /; /θ/ with /f/;
/ð/ with /d/; /ð/ with /z/; /ð/ with /v/ at the initial and final positions in words .The
medial position was not included because there are not many minimal pairs
obtaining the target sound pairs. When the students cannot distinguish /θ/ and /ð/
with the experimental sounds, they have tendency to substitute /θ/ and /ð/ with
them. As a result, the listening experiment predicts the students’ errors of /θ/ and /ð/
pronunciation. It also oriented to redesign recording experimental samples when
conducting recording experiment, to decide suitable pronunciation activities when
running teaching experiment later. The listening sample is shown at appendix 3 (see
appendix 3).
28
Listening experiment was carried out on four classes 10cb1, 10cb2, 10cb3,
10cb4.
2.3.3.2 Teaching experiment
Gu (2003) stated that personalities including language proficiency, gender, and age
are the most important factors that influence one’s success as a language learner.
Therefore, it is essential to consider those factors considerately before teaching
experiment so that the experimental results will be trustworthy. Two classes: 10cb3,
10cb4, taught /θ/ and /ð/ by the researcher, were selected as the experimental
groups. Also two classes: 10cb1, 10cb2, taught /θ/ and /ð/ by two teachers of
English 10, were as the control groups.

The teaching experiment was carried out on Microsoft PowerPoint to the two
classes 10CB1, 10CB2. The researcher taught 10cb3 /θ/ and /ð/ in lesson speaking
of unit 12 Music. The class 10cb4 was taught /θ/ and /ð/ in language focus lesson 14
The World Cup.
It took fifteen minutes for the researcher to teach /θ/ and /ð/ in the two lessons. The
warm up activities were combined with pronunciation activities. The warm up and
pronunciation activities of unit 12 Music and unit 14 The World were shown in CD
accompanied with the thesis (watch attached CD).
29
2.3.3.3 Recording experiment
The recording method is a very useful tool to evaluate students’ pronunciation.
It also helped the researcher compare the pronunciation of 10cb1, 10cb2 with
10cb3, 10cb4.
2.3.3.3.1 Pre recording
The four classes 10cb1, 10cb2, 10cb3, 10cb4 was chosen to carry out the
experiment. The pre recording was carried out to check how well the students
pronounced /θ/ and /ð/, to evidence the students’ error pronunciation, to confirm the
listening experiment as well. It was carried out with a recording sample formed in
two parts: reading individual words containing /θ/ and /ð/, reading sentences using
words comprising /θ/ and /ð/. There are carefully-selected 18 words which are very
popular. The words are shown at the below table

Moreover, the researcher used four sentences (1, 2, 3) using minimal pairs of /θ/ and
/ð/ to check the distinguish /θ/ with /t/, /θ/ with /s/, /ð/ with /d/. Those minimal pairs
were employed based on predictions of the listening experiment. Intentionally, the
number of words using /θ/ and /ð/ are equalized by the researcher so as to collect
and analyze the data easily later. The full pre recording sample was added in
appendix 4(see appendix 4).
2.3.3.3.2 Post recording (see appendix 5)
The post recording is to compare the pronunciation of experimental 10cb1, 10cb2
group and control 10cb3, 10cb4 group. The format is like pre recording.
2.4 Research procedure
The data collection was conducted in the following basic steps taken at different
period to ensure the progress of the research.
Step 1: Writing the thesis proposal (1/11/2011 – 31/12/2011)

CHAPTER 3 RESULTS AND DISCUSSIONS
3.1 Results
3.1.1 Result of listening experiment
The researcher let the students listen to spoken minimal pairs made by natural
reader program. The result is shown below
Table 3.1.1 The students’ ability of distinguishing minimal pairs of /θ/, /ð/
No Minimal pairs Options, number and percentage
Same Different
1 Face- faith 128 91.4% 12 8.6%
2 Thing –Sing 2 1.4% 138 98.6%
3 Thought- Taught 130 92.9% 10 7.1%

8 Clothe- close 10 7.1% 130 92.9%
9 That – Vat 0 0% 140 100%
The table evidences that students had difficulties in distinguishing phonemes: /s/ vs.
/θ/; /t/ vs. /θ/; /d/ vs. /ð/. Initially, the students could not recognize the difference
between face and faith (128-91.4%). Although they met difficulties in final /s/ vs.
/θ/, they could tell the difference of thing-sing (138-98.6%).The minimal pair
34
thought-taught was another problem. There were 130 students out of 140 (130-92,
9%) ticking same. In contrast, the students could figure out difference of bat and
bath (138-98.6%).Then, the experimental minimal pair: dare-there was also hard to
the students. There were 139 students (139-99.3%) choosing the same scale.
Finally, the students could pick the rest minimal pairs out. In brief, the students got
stuck at making clear minimal pairs bearing /s/ vs. /θ/; /t/ vs. /θ/; /d/ vs. /ð/ at the
both initial and final position of words.
3.1.2 Result of pre-recording experiment
The pre recording was carried out with 140 students. The students read 18 words
containing / θ/, /ð/ and 14 sentences using words containing /θ/, /ð/. The results are
shown below

The figure shows that students replaced /θ/ with both English and Vietnamese
consonants, omitted /θ/. With English consonants, the students replaced /θ/ with /t/
and /s/ but a few students mispronounced (3 out of 140 (2.1%) students substitute
/θ/ with /t/ at the initial of a word; 5-3.6% students exchanged /s/ for /θ/ at the
final).With Vietnamese consonants, they substituted /t’/ and /s*/ for /θ/. Majority of
the students replaced /t’/ for /θ/ at the both initial and medial position (137-97.9%)
students obtained initial, 140(100%) students obtained medial).They also replaced
/s*/ for /θ/ at the final (19-13.5% students). The final /θ/ is really tricky because the
students did not only replace it with /s/, /s*/ but also omitted it. There are 116-
(82.9%) students left /θ/ out. Generally speaking, the students got deep influence on
Vietnamese when pronouncing /θ/.

The figure illustrates that students replaced /ð/ with both English and Vietnamese
consonants, omitted /ð/. With English consonants, a few students replaced /ð/ with
/d/ at initial and medial positions. (4 out of 140( 2.9%) students substituted /ð/ for
/d/ at the initial, 7 out of 140(5%) students exchanged /ð/ for /d/ at the final).With
Vietnamese consonants, they substituted /d*/ for /ð/. A large number of the students
replaced /ð/ for /d*/ at the both initial and medial position (136 students (97.1%)
obtained initial, 133 students (95%) obtained medial. Like final /θ/, the final /ð/ is
extremely hard phoneme because all the students omitted it. Generally speaking, the
students got deep influence on Vietnamese when pronouncing /ð/.

The table shows that no students could pronounce /θ/, /ð/ in experimental minimal
pairs in sentences correctly. As a tendency, they did not only mispronounce /θ/, /ð/
but also replaced /t /, /s/, /d/ of experimental minimal pairs for /t’/, /s*/ /d*/

/, /s/, /d/ of experimental minimal pairs for /t’/, /s*/ /d*/. The students mostly
replaced /d/ for /d*/ (140-100%); /s/ for /s/ (140-100%).They also substituted initial
/t/ for /t’/ (110-78.6%). In brief, the student mainly used Vietnamese /t’/, /s*/ /d*/ to
pronounce experimental minimal pairs in sentences.

3.1.3 Result of observation analysis
Two forty- five minute classroom hour observations were conducted on language
focus lessons taught by the two teachers. Those lessons were Unit 12, Lesson E and
Unit14, Lesson E. A large number of results were obtained. Because of the main
purpose of the study, the target results were presented only. Below are the results
from the observation sheets

The table shows that the teachers’ pronunciation activities were not very various.
Most of them loved to use sound bingo (both 2 teachers) and odd one out was used
by only one teacher. Other activities were not used by the two teachers. In general,
those teachers liked simple pronunciation activities taking less time.

Generally speaking, the pronunciation activities the teachers organized brought
certain benefits to the students, but the benefits were not very noticeable. The
teachers’ pronunciation activities capturing their students ‘interest was rather
suitable. However, the student did not receive enough explanation of place and
manner of articulation of the target sounds, native English input language as well;
so, they could not perform the target sounds well.
3.1.4 Result of questionnaire analysis
3.1.4.1 Questionnaire for the teachers
45
The questionnaire was delivered to five teachers who are teaching English 10. It
investigated teachers’ attitude to teaching pronunciation, realities of teaching /θ/, /ð/
pronunciation as well. It also employed textbook analysis which mainly collects
teachers’ opinions.
Figure 3.1.4.1a Teachers’ attitude to the importance of teaching pronunciation
The figure shows that all teachers agreed with necessity in teaching pronunciation
(1 teacher thought it was very important, 3 teachers assumed it is important, the rest
believed it was rather important). No one thought that teaching pronunciation was
unimportant. In general, the teachers highly evaluated the importance of teaching
pronunciation.

As can be seen from the figure, the teachers’ attitude to correction of their students’
pronunciation errors was at neutral rate of frequency. There were 3 teachers usually
correcting their students’ pronunciation error (60%). And 2 teachers obtained
sometimes option (40%). In general, the teachers’ frequency to correction of their
students’ pronunciation errors was not so high.
Figure 3.1.4.1c Teachers’ time of teaching pronunciation
The figure evidences that teachers’ time of teaching pronunciation was not much. It
took from ten to five minutes for the teachers to teach pronunciation in language
focus lessons. Three teachers got hold of ten minutes and two teachers obtained five
minutes. In brief, teachers spent less time on teaching pronunciation.

Figure 3.1.4.1d The teachers’ combination with other lessons to teach
pronunciation
The figure demonstrates teachers’ frequency of pronunciation teaching combination
with other lessons. As we can see, they mainly taught pronunciation in language
focus lessons (4 out of 5 teachers (80%) obtained always, 1(20%) took usually).
They also combined pronunciation teaching with speaking and listening lessons,
which took less frequency than language focus. (1-20% teacher sometimes jointed
pronunciation teaching with listening lesson; 1-20% teacher sometimes combined it
with speaking). They rarely taught pronunciation in reading lesson (5 teachers
(100%)) In general, the teachers mainly taught pronunciation in language focus
lessons.

As we can see, there were 2 teachers judged teaching pronunciation in speaking
lessons, 2 teachers agreeing teaching pronunciation in language focus. Only one
teacher chose pronunciation teaching in listening lessons. No one chose teaching
pronunciation in reading lessons. In summary, numerous teachers considered that
pronunciation should be taught in speaking and language focus lessons.

As we can see, many teachers thought that adding articulative pictures and tables
textbook was necessary. There are 3 teachers (60%) agreed that adding extra
articulative pictures was very necessary and the rests reflected that it was necessary
and rather necessary. Most of teachers believed that adding articulative tables was
necessary, but they did not think that adding articulative tests was necessary. In
brief, the teachers supported adding articulative pictures and tables into textbook.

20% got hold of sometimes option) However, they rarely compared English
consonants with other easily-mistaken English consonants.( 80% choose rarely

to pay attention to the students ‘ways to transcribe the fricatives /θ/ and /ð/). The
teacher rarely used shocking and funny words and sentences containing the
fricatives /θ/ and /ð/ for students to practice (80%). The teachers did not pay much
attention using pictures and videos to teach pronunciation. (100% of teachers rarely
used videos, 40% sometimes used pictures and 20% obtains rarely).The students’
input language mainly was taken from their teachers (80% self modeled the target
sounds to their students). In general, the teachers used few hints of teaching
pronunciation and input language was not ideal.

3.1.4.2 Questionnaire for the students
The questionnaire was handed out to 140 students (82 female, 60 male) and 140
questionnaires were collected. The questionnaire is to investigate students’ attitude
to English learning in general, English pronunciation, and realities of students’
study pronunciation /θ/ and /ð/.

differently-pronounced word from the others. There were not many students learned
pronunciation from their teacher model or native speaker. The student just learnt
English pronunciation in theory not real practical English. In brief, they learnt
English pronunciation with English texts not real sound.

classroom (73.6%).Never did the students speak English with foreigners (98.6%).
The other sources of real English which the student rarely used, 75.5% of the
students rarely watched movies teaching pronunciation on internet, as an example.
In brief, the students learnt English passively and unproductively.

pronunciation at Thanh Binh 2 High School. The following points are the most
remarkable.
Learning and teaching pronunciation of /θ/ and /ð/ in Thanh Binh 2 high school was
facing many problems. Even though most of the students liked to learning English
pronunciation and the teachers highly evaluated the important role of it (see figure
3.1.4.1a and figure 3.1.4.2 a), the students’ pronunciation was still at less
proficiency. Initially, the teachers did not have much time to teach pronunciation
(see figure 3.1.4.1c), as a result, both teachers and students did not have many
pronunciation activities (see table 3.1.3a, table 3.1.4.1a). Then the students did not
get clear explanation of the target sound. The teachers rarely used pictures and
videos to teach pronunciation. When teaching the target sounds, they themselves
modeled the target sounds. No native English pronunciation sample was carried out
in class (see table 3.1.3b, table 3.1.4.1b and table3.1.4.2b), and the students
gradually fell back on Vietnamese when they pronounce English, even used
Vietnamese scripts not IPA to transcribe English.( see figure 3.1.4.2e and figure
3.1.4.2 g).The students rarely took note in pronunciation teaching hour. They just
wrote the headline “/θ/ and /ð/ pronunciation”. (see table 3.1.4.2c). Next, they
mainly used their own dictionaries to learn pronunciation and most of the students
were shy to learn pronunciation by imitating teachers’ mouth movements. (see figure
3.1.4.2c and figure 3.1.4.2d). It was able to be a real disaster of pronunciation when
the students just learnt pronunciation in theoretical not practical. Finally, the
students’ English environment was not perfect. Rarely did the students practice
English with foreigners. They also were lazy to learn English pronunciation online
(see figure 3.1.4.2h). In conclusion, both the students and teachers were suffering
from English pronunciation of /θ/ and /ð/.
3.2.2 Research question 2:
63
(2) What phonemes the students replaced /θ/ and /ð/ with?
The data analyzed from the listening and pre-recording experiments of the students
evidenced both English and Vietnamese phonemes which the students replaced /θ/
and /ð/ with. The following points are the most remarkable.
The listening experiment’s results show that students had difficulties in
distinguishing phonemes: /s/ vs. /θ/; /t/ vs. /θ/; /d/ vs. /ð/ (see table 3.1.1). As a
result, they had great tendency to substitute /θ/ for /s/; /t/ for /θ/; /d/ for /ð/ when
they read the pre-recording sample. However, a few students replaced /θ/ and /ð/ for
English phonemes /t/, /s/, /d/ because they mostly substituted /θ/ and /ð/ for
Vietnamese phonemes: /t’/, /d*/ or omitted /θ/ and /ð/ at final position of words.
(see figure 3.1.2a, figure 3.1.2h). In addition, they did not only mispronounce /θ/,
/ð/ but also replaced /t /, /s/, /d/ of experimental minimal pairs for /t’/, /s*/ /d*/ (see
figure 3.2.1l). In brief, the students replaced mostly /t’/, /d*/ for /θ/ and /ð/ or
omitted final /θ/ and /ð/.
3.2.3 Recommendations (Research question 3: )
(3)What solutions to the problems for both teachers and the students?
General speaking, learning and teaching /θ/ and /ð/ pronunciation in high school
were short of sufficient drills and practice. Despite having some knowledge about
pronunciation of these the target sounds, the teachers did not have many
opportunities to teach their students. The students’ wrong pronunciation were ,
therefore, inevitable for the students who are learning English as a foreign
language in a tricky environment. Due to the study was conducted in a short time,
the research only a few suggestion solutions for teachers and students.
*For the teachers:
Bettering textbook
The teachers should prepare the picture describing places and manners of
articulation of /θ/ and /ð/ and photo them in advance. When the teachers teach the
64
two sounds, they deliver the pictures to the students. Then, they ask their students
stick the pictures to their notebooks (the pictures should be small enough to fit with
their notebooks).
Dealing with shortage of time
The teachers should use warm up activities whose products are words bearing /θ/
and /ð/ sounds. The activities can be Blackboard Bingo, Brainstorm round a word,
Jumbled words, Crosswords, Feel the object, Guessing, Thought bubble Dictation,
Kim’s game, Who, where, what, etc. The activities’ answers from the students
should be spoken English, so they have to speak out the warm up’s answers. Then
the teachers use these words to teach /θ/ and /ð/.
Adapting to other lessons
The teachers should teach pronunciation in speaking lessons if the lessons requiring
many reviewing vocabularies. Intentionally, the teachers initially use many words
containing the target sound in warm up activities. Use the words to carry out
pronunciation activities like, Odd one out, Minimal pairs, Bilingual minimal pairs,
Whisper, Sound Bingo, Silent speech. And teacher gives the meaning of these
words. Pronunciation activities now are similar to pre-speaking because the students
are guided both pronunciation and meaning.
Dealing with students’ taking note
Ask the student to write description of place and manner of articulation of the /θ/
and /ð/ into their note book “place the tongue between teeth when pronouncing /θ/
and /ð/, /θ/ is unvibrated but /ð/ is vibrated, /θ/ and /ð/ are not the same as
Vietnamese consonants /t’/, /d*/”
Creating positive atmosphere for classroom
The teachers lightly punish the students if they pronounce the /θ/ and /ð/ incorrectly
by asking them stick their tongues out of their mouth in thirty seconds. This
65
punishment just helps the students practice their tongues; place their tongue at the
medial upper teeth and lower teeth.
The teachers should deliver each of their students a small piece chewing gum, at
the end of classroom hour. At that time, the teachers told their students use their
tongue to push the chewing gums out of their mouths, releasing the air. This small
activity just reminds the students of placing their tongues between their tongues.
Bettering pronunciation activities
Let the students practice /θ/ and /ð/ from simple to complex. First, ask the students
add vowels to form simple syllables: “the, the, the”, “tho, tho, tho”, “thu, thu, thu”,
and try changing the position of the sounds as well, such as in “eeth, eeth, eeth” or
“ath, ath, ath”. Then, acknowledge that the students feel comfortable with
producing /θ/ and /ð/ in simple syllables, ask the students add more consonants
vowels to make complete words. The- there; tho- thought; thu- though, for instance.
** For the students:
- The students should use mirrors to practice /θ/ and /ð/ at home, place their figures
against their lips and try to touch their figurers by their tongues
- The students need to practice their mouths more often by moving their tongues up
and down, backward and forward.
- The students need to record their /θ/ and /ð/ pronunciation, and ask their teachers
to evaluate their performances.
- Practice minimal pairs: thought- taught; mouth- mouse; they-day, etc.
- Practice the sentence: Theirs mothers thinks about this thing, that thing, and those
things.
- Practice sayings:
+A bird in the hand is worth two in the bush.
66
+Don't look a gift horse in the mouth.
+Truth is stranger than fiction.
+You must do the things you think you cannot do
+ Early to bed and early to rise,
Makes a man healthy, wealthy, and wise.
***For the High School
- The High School needs to equip more projectors to help the teachers use Microsoft
PowerPoint to teach /θ/ and /ð/, let the students can watch movies teaching /θ/ and
/ð/ as well .
- The High School needs to provide more English lab to help the students to have
good English environment.
CONCLUSION
1. Overview of the study
Generally, this part presents the conclusion of the study about /θ/ and /ð/
pronunciation of the students at Thanh Binh 2 students. It investigated realities of
teaching and learning /θ/ and /ð/, found out what sounds which the students
replaced /θ/ and /ð/ with. As the questionnaires and observation’s results evidenced,
pronunciation teaching /θ/ and /ð/ was carried out fast and carelessly. It took
teachers about five minutes to deliver the target sounds and got students to practice
them. The teachers rarely organized numerous pronunciation activities; prepared
pictures describing place and manners of the target sound articulation as well.
Furthermore, the thesis’s experiments also demonstrated that the students’ error
pronunciation mainly caused by influences of Vietnamese. The students mostly
replaced /θ/ and /ð/ for /t’/, /d/. With the thesis’s findings, the researcher hope that
they will help the students and teachers improving learning and teaching /θ/ and /ð/,
sharpening the students’ pronunciation of /θ/ and /ð/.
67
2. Limitations of the study
Although the study was conducted with the researcher’s great efforts, it still has
limitations. Because the researcher spent only two months on researching both
teachers and the students, the study is limited with researching time. The
researchers just managed to deliver only two experimental classroom hour.
Moreover, the thesis was researched with not ideally many participants. As a result,
the students’ recording and listening experiments just were carried out with four
classes. Those are limitations of the study.
3. Suggestions for further research
It is essential to consider the following suggestions for further research that is
