ABSTRACT In teaching vocabulary in general and ESP vocabulary in particular, teachers employ many
techniques and activities in order to help their students retain learned lexical items.
Therefore, this thesis is carried out with the aim to: (1) investigates the difficulties
encountered by the second year students at AETD, SDU when learning ESP vocabulary,
(2) to find out the techniques/ activities that teachers at SDU used in teaching ESP
vocabulary, and (3) to find out how far the use of simulation tasks improve ESP
vocabulary for the second year students at AETD, SDU.
To achieve the given aim of the study, a pre – task survey questionnaire and a post – task
questionnaire have been designed to gather information from 170 students. The findings
show that pronunciation and retention of word meaning are factors prevent students from
mastering vocabulary and among various techniques employed by the teachers at SDU,
simulation tasks prove its effectiveness in the ESP vocabulary improvement of the
students.

LIST OF ABBREVIATIONS


vocabulary, particularly specialist vocabulary (or terminology), is a key element of ESP.
At Sao Do University, ESP is offered to both English majors and non – English majors.
However, ESP vocabulary teaching and learning have not been paid enough attention and
still far from satisfactory due to many reasons such as course book, mixed – level students,
large class, low learner motivation and poor participation. Thus, it is necessary for teachers
to create an active and motivated learning environment to get students to involve in
learning vocabulary.
Among various kinds of techniques, simulation is defined as “reality of function in a
simulated and structured environment” (Jones, K. 1982). Simulation with its
characteristics and advantages is considered one of the most useful activities that can help
students enlarge their vocabulary. Moreover, up to now, there has been little research on
the application of simulation tasks in improving ESP vocabulary for foreign language
learners.

2
For the above reasons, the author would like to carry out this research entitled, “Using
simulation tasks to improve ESP vocabulary for the second – year students of
Automotive Engineering Technology Department at Sao Do University”. The author does
hope that this study will help the teachers in some ways to find appropriate teaching
method to improve vocabulary for their students.

2. Aims of the study
The study aims at investigating the use of simulation tasks to improve vocabulary among
the second year students at Automotive Engineering Technology Department (AETD),
SDU. The main purposes of the study are summarized below:
1. To investigate the difficulties encountered by the second year students at AETD,
SDU when learning ESP vocabulary.
2. To find out the techniques that teachers at SDU used in teaching ESP vocabulary.

PART B: DEVELOPMENT

CHAPTER 1: LITERATURE REVIEW

As mentioned above, vocabulary plays an important role in learning and teaching a
language. Many techniques and activities are employed to enlarge learners’ vocabulary.

However, Dougill (1987) in “Drama Activities for Language Teaching” states that
“Simulation can be defined as a structured set of circumstances that mirror real life and
participants act as instructed”. Meanwhile, in “Simulations in Language Teaching” it is
defined as “reality of function in a simulated and structured environment” Jones, K (1982,
p5). This definition shows three essential elements in simulations: reality of function,
simulated environment, and structure. The researcher further states that reality of function
is the key concept in simulation.
The two definitions agree in that simulation “mirror real life” and “reality of function in a
simulated and structured environment”, which means that simulation is not real life, it is
only a type of simulating real life in a simulated environment.

1.1.2. Characteristics of simulation
Jones (1989) draws the characteristics of simulation as follows:

1.1.2.1 Reality of functions
This covers not only what the participants say and do, but also what they think. They must
mentally accept the function the simulation requires of them. They must stop thinking of
themselves as students, and avoid standing one step away from their own activities. They
must step inside the function mentally and behaviorally, and do the best they can to carry
out their duties and responsibilities in the situation in which they find themselves.
The most important part of simulations is having participants accept the reality of function
(role and duties) fully, not thinking as students but taking the role; otherwise the simulation
simply will not work. Acceptance of the reality of function means that a participant who
has the function of doctor must examine the patient, communicating effectively to do the
job. The role of students in simulations, therefore, is (1) taking the functional roles such as
reporter, survivor, or customer as a participant, (2) stepping into the event, and (3) shaping
the event, carrying out their duties and responsibilities. (as citied on Lyu, Y, 2006, p13)
1.1.2.2 Simulated environment
The environment must be simulated; otherwise it is not a simulation. A learner - driver
under instruction on the roads, or a student-teacher involved in classroom practice, or a

situations. In this sense, they bridge the gap between the classroom and the world outside
the classroom.
c) They can be used for assessment and feedback purposes at the end of a textbook unit.
d) They can consolidate learning and allow students the opportunity to discover their own
level of mastery over specific language content.

7
e) By simulating reality, they allow beginning students and EFL students to feel that they
are really using the language for a communicative purpose.
f) They heighten students’ self-esteem and improve their ability to work cooperatively.
g) They allow students to experiment with language they have learned.
h) They allow students to express who they are, their sense of humor, and their own
personal communication style.
i) They offer good listening practice.
j) They provide an opportunity for practicing the rules of social behavior and the various
sociolinguistic elements of communication.
k) They engage the learner physically. This involves the learner more fully and can be an
aid in language retention.
l) They can be liberating for many students who may enjoy expressing themselves through
a role or a mask but may be inhibited about expressing themselves otherwise during the
class.
m) They provide a context for understanding attitudes, expectations, and behaviors related
to the target culture.
n) They may be used as a stimulus to discussion and problem solving.
o) They can be extensions of more controlled practice using dialogues.
Furthermore, Sam (2008) has drawn the advantages of using simulation as the teaching
technique in ELT as follows:
a) Stimulates authentic conversations
b) The fluency activities.
c) Suitable for consolidation.

3) Activity: This is when the actual simulation activity takes place. During this time, we
play the roles of discussion, coach and referee. At times, students may not grasp the point
of the simulation. We may find it necessary to stop the action for a moment to help pupils
think about their decisions and to explain the purpose of the activity.
It is common for disputes to arise during simulation activities. Often there are situations for
which the rules fail to provide a specific action guideline. When this happens, we need to
intervene and make a ruling that will allow the simulation to continue.
4) Debriefing: This is a critical important part of any simulation activity. During
debriefing, we lead a discussion highlighting various events that occurred during the
activity. The discussion help students recall things that might have escape their notice
during the fast pace of the activity itself. Debriefing discussions sometimes focus on
specific decisions made and their desirability relative to alternatives. Sometimes,

9
debriefing concerns the design of the simulation. Often, individuals will want to critique
their own performances and suggest ways they might act differently were they to do the
exercise another time.
Jones (1989) particularly emphasizes that the procedure of simulation should include the
following steps:
1) Decide on the priority of aims – icebreakers, assessment and so on
2) Estimate the interactive language competence of the students
3) Search a wide area, including simulation literature
4) If the language level is suitable, then examine the mechanics of the simulation: time,
numbers, hardware, space, organization and so on
5) If it seems suitable, then participate in it personally
6) Consider whether it needs adapting, but bear in mind that over adaptation can kill a
good simulation by removing or altering elements which help the simulation to run
smoothly in practice.

1.2 Vocabulary

Grammatically, vocabulary items are classified into different parts of speech such as
nouns, verbs, adjectives, adverbs, prepositions, pronouns, etc. Each part of speech has it
own position complying with certain grammatical rules and relating to others.
Morphologically, vocabulary is separated into simple words, derived words and compound
words. Simple words consist of a root morpheme; derived words comprise of a root and
one or more derivational morpheme and compound words have at least two roots with or
without derivational morphemes.
However, methodologically, vocabulary is categorized into active and passive vocabulary
or productive or receptive vocabulary. The words which learner can understand, pronounce
correctly, use effectively in speaking and writing are active words. The words which
learner can recognize and understand when they occur in a context, but which he cannot
produce or use correctly himself even when he wants to are passive words.
A foreign language teacher should understand these classifications in order to choose the
most relevant words that suit the learners’ level of proficiency so that they can enlarge
their vocabulary actively and productively.
1.2.3 The role of vocabulary in language learning
Regarding the function of vocabulary in language teaching and learning, Wilkins (1972,
p.11) stresses that “vocabulary is one of the three dimensions of a language (phonetic,
grammar, vocabulary). Without grammar, very little can be conveyed, without vocabulary,
nothing can be conveyed”. To talk about the importance of vocabulary McCarthy (1990:

11
viii) also states that no matter how well the student learns grammar, no matter how
successfully the sounds of L2 are mastered, without words to express a wider range of
meanings, communication in an L2 just cannot happen in any meaningful way. It can be
seen that one can use grammar correctly, but he cannot express himself properly because
word source is inadequate. Reed (2000, p. 1) agree that words are the basic building blocks
of language, the units of meaning from which larger structures such as sentences,
paragraphs and whole texts are formed. Thus, to become a successful communicator in a
foreign language, it is important to master the meaning as well as the use of a word.

irregularity in the word.
1.1.4.2 Meaning
According to Nations (2001, cited in Milton, 2009, p.14) word meaning can be divided into
three parts. The first sub-division, form and meaning, is the part most of us will think of in
terms of knowing a word. It involves being able to link the form, however it occurs, to a
meaning, and often in a foreign language this involves forming a link between a foreign
language word and its translation in the native language. Languages are not exactly parallel
to each other in the way they use their vocabulary, however. The other sub-divisions,
concepts and referents and associations, indicate, therefore, that a word in one language
might require several translations or carry subtly different meanings and associations in
another language. A word such as “fat” carries very negative connotations in English when
describing a person, and native speakers should use this word with some care.
It should be noted that meaning of words is closely related to each others. There are
various such relationships as synonyms, antonyms, hyponym, chunks of language, etc.
Thus, the teacher is required to select and decide on which meaning and how many
meanings of a word to teach in a given class time to help learners avoid confusion.
1.1.4.3 Usage
Knowing how to use a word appropriately and effectively is considered one of primary
aspects that both learners and teachers have to pay attention to. Nations (2001, cited in
Milton, 2009, p.15) also categorizes knowledge of word use is also divided into three parts.
Grammatical functions concerns knowing what part of speech a word is and how it will
link with other words as a consequence. If you know the word young, for example, and
know that it functions as an adjective, then in English it should be placed before the noun it
qualifies and not after: a young woman is right, therefore, but a woman young is not. The
collocations sub-section refers to the company words like to keep. Some words occur very
frequently alongside certain others and these words are said to collocate with each other. A
frequent English verb such as do forms many phrasal verbs with prepositions (do up, do in,
do away with), and links with nouns and noun phases (do homework). Some words are

 Scales – if students know 'big' and 'small', for example, other steps could be to
teach 'short' and 'long' etc.
 Examples of the type – give examples of words you want to introduce.
 Translation – it has been the most widespread activity used for presenting the
meaning of a word in classes.

15
 Guessing from the context, matching/labelling – learners match words to words
or sentences or pictures. It belongs to so called discovery techniques: they
activate the learner’s previous knowledge of a language and initiate the work with
the new vocabulary. Discovery techniques demand the autonomous students with
higher knowledge of English.
Taking into consideration the specific factors of ESP vocabulary teaching, we can see
“many of the techniques traditionally used in ELT work can be exploited in ESP
vocabulary teaching especially at the early stages when both subject and linguistic content
are at an elementary level” (Kennedy and Bolitho, 1984, p.59). Consequently, presenting
ESP vocabulary can be fully realised by methods and techniques mentioned above. Often
even translation may be useful, necessary and appropriate because of the level of students
at the vocational secondary schools and to avoid the fatal misunderstanding. During
presentation vocabulary, teachers have a great opportunity to explain the purposeful
meaning of a word in the context of the real life and work at the school workshops.
However, this kind of presentation should be simple, interesting and amusing to motivate
and encourage students’ interest.
1.3.1.2 Practising techniques
Presenting a word in the class does not secure that it will be remembered for a long time.
There are many practice activities that include repeating the new vocabulary to fix the new
words in the learners´ memory. The practice activities are divided into two main groups:
receptive and productive.
According to Thornbury (2002, p.94-99) receptive practice (the learner does not really
produce the target words) includes these following types:

Redman (1986, p.137) warn against “a certain degree of stress involved in productive
practice”. According to them, practice should be challenging, but not frustrating or
stressful for the learner. They give several arguments in favour of productive practice of
vocabulary in the classroom; above all, it promotes fluency and improves pronunciation, it
helps the memory to store words, and retrieve them later, conversation in English is very
motivating and it builds learner’s confidence. Learners expect to get the opportunity to
practise new language.
Another division includes spoken and written practice. Many vocabulary activities used in
the class are based on discussions, dialogues, descriptions, role-play activities, or different
written tasks. 17
1.3.2 Vocabulary teaching in ESP
Most learners acknowledge the importance of vocabulary acquisition. According to
Thornbury(1) “the acquisition of new words is the process which never stops”. To build a
good storage of vocabulary is the first and one of the most important steps when starting to
learn a new language. People learn new words permanently and identify their meaning.
Vocabulary learning does not officially belong to the language skills (listening, speaking,
reading and writing) but there is no way of making advance in language without building
vocabulary that can be applied into grammar structures and make meaningful utterances. It
is difficult for students to communicate without creating and developing their own lexicon.
English for Specific Purposes (ESP) represents a specific reason for learning a foreign
language. There are distinguishedly two types of ESP: English for Specific Purposes and
English for Academic Purposes (EAP). At present these streams include a lot of other
fields, e.g. English for Technicians. According to Hatch and Brown (1995, p.312), “special
lexical items are present in nearly all professions, and each branch has special vocabulary
to cover abstract concepts”. Kennedy and Bolitho (1984, p.56 - 58) distinguish these word
categories for teaching technical vocabulary:
• Technical Abbreviations, Symbols and Formulae: they partly cause the problems.

areas that they are interested in.
ESP vocabulary can be practised and consolidated by similar methods and techniques used
for practising and consolidation of general vocabulary. Writing tasks can include reports
and different instructions for car processing, making summaries from technical journals,
describing processes and techniques, labelling diagrams and pictures, describing graphs
and comments on charts etc.

1.3.3 Simulation tasks in ESP vocabulary teaching
1.3.3.1 Simulation tasks
Methodologically, tasks are often the central part of the practical learning activity.
According to Oxford (2006, p.97), in second language teaching and learning, task is now
often viewed as an outcome oriented instructional segment or as a behavioral framework
for research or classroom learning.
The main idea of task-based learning is that students study more effectively when their
brain is occupied with a specific task or topic offering, besides concentration on language,
its grammar or vocabulary, also another practical experience, e.g. solving problems or
making decisions. In this way, students are forced to communicate in the target language
and therefore they use a wider range of language items, not only a particular pattern or
vocabulary group. Tasks may include projects for producing pictures, presentations,
