Keywords: Vocabulary and Demonstration Technique

This research investigated the use of demonstration technique in teaching vocabulary. The use of demonstration technique gives students an opportunity to active and helps each other in teaching learning process in order to master the subject material. The method that used in this research is experimental research. The experiment research design applied in this study was a quasi experiment. It means that the writer as an observer taught English directly in the class. The study was conducted following procedures of the quasi experimental research; there were two classes for the research, namely experiment class and control class. The subjects of the study are 7.F and 7.G, with 7.F is chosen as an experiment class and 7.G as a control class. Before starting the treatment, the writer gave pre-test to

know the students’ competence toward vocabulary especially English vocabulary. After giving the pre-test, in the first meeting the writer taught the vocabulary by using demonstration technique in experiment class and by using conventional technique through rote memorization learning in control class. Then the last meeting, the writer gave post-test to find out whether there was an effectiveness using demonstration technique in teaching vocabulary.

The result of data analysis using t-test showed, the value of thitung is 5.38

with degree of freedom 62 in the significance degree (α) of 5%, tt is 1.67, then in

the significance of 1% = 2.38. It means that, to > tt (thitung is higher than ttabel). So,

the null hypothesis (Ho) is rejected and the alternative hypothesis (Ha) is accepted,

A.

Background of the Study

Language is used by people as written, oral, or action symbol to give

information. Brown defines language as “a system of arbitrary conventionalized vocal, written, or gesture symbols that enable members of given community to

communicate intelligibly with one another.”1

In other words, people using

language as a means to express inner thoughts and emotions, and to interact with

other people. Therefore, language is important aspects in people’s life to communicate.

Because language is important aspect in people’s life, In Indonesia many

people have foreign language mastery to communicate with other people around

the world. That is English language.2 It is as International language that is used

in order can be understood by the people in the world in communicating.3

Therefore, English is important to be learnt by the people in the world.

English is important to be learnt because it is taught from elementary and

up to university level, as compulsory subject. Although for other students,

English is assumed as difficult subject. Based on the writers’ observation when doing Praktik Profesi Keguruan Terpadu (PPKT) in junior high school, the

writer found that the difficulties in learning English is about the English content,

such as grammatical function, pronounce of words, and vocabulary.

From those difficulties, one of basic and main difficulty as a problem for

students is difficulty in learning vocabulary, especially English vocabulary. The

problem is because the students have limitation knowledge of vocabulary. It can

be the major or crucial problem confronting students of English as foreign

language (EFL). According to Saengpakdeejit in his study “limited vocabulary knowledge can be a crucial problem which leads the learners to encounter

difficulties in language learning.”4

In other words, limited vocabulary for

students is a major factor that influences the EFL students in learning English

becomes difficult. It means if the students do not have vocabulary mastery, the

students cannot master English skill comprehension fluently. Richards and

Renandya define that “vocabulary is a core component of language proficiency and provides much of the basis for how well learners speak, listen, read, and

write.”5 However, the vocabulary contributes toward the students’ comprehension when learning English skill.

The problems in vocabulary for the students especially for non-native

students usually it influenced some factors. Based on the writer’s observation when teaching English, the factors are caused by students or by English teacher.

Some factors are faced by students such as some students think English

vocabulary are difficult and complicated in pronunciation of words, and then

some students are lazy and confused because English vocabulary has a lot of

meaning in one word. The possible factor posed by English teacher is when using

teaching technique, which is the students get boring and have low motivation in

learning process because teaching technique which used by English teacher is not

interest. Therefore, from those factors can be changed by the English teacher

primary, because the English teacher has main role in teaching and learning

process for students.

In teaching and learning process, the English teacher’s role is to give solution for students who get difficulty in learning vocabulary. The role is by

using a variety of teaching technique. There are many teaching techniques can be

used by English teacher, such as peer-tutoring, demonstration, games, discussion,

etc. Although there are many techniques, but the teacher needs an alternative way

to help students encourage their anxiety and motivate them to learn better, and

then make the students are interested in learning vocabulary process. In this case,

the writer tries to give alternative ways to overcome the problem in teaching and

learning vocabulary, which is by using demonstration technique.

Demonstration technique maybe can help to enrich the students’ vocabulary. The meaning of words can be communicated or taught includes most

of possibilities is by using demonstration. This technique, the information source

by using an object, a cut-out figure, gesture, action, photographs, blackboard

drawings or diagrams, and pictures.6 Finally, this way can be used by the teacher

to make the lesson more interesting because the students can play the objects with

social interaction and then it will build up the new atmosphere for students in

learning English. Therefore, the English teacher can apply it in teaching

vocabulary.

Based on the statement above, the writer is interested in conducting a

research and decides to discuss and consider that there is the effect of teaching

technique through demonstration technique to improve the students’ vocabulary score in teaching and learning English. In this study, the writer decided design a

problem to be researched with the title “THE EFFECT OF DEMONSTRATION TECHNIQUE TOWARD THE STUDENTS’ VOCABULARY”.

B.

Identification of the Problem

The problem in learning English may be started at the process of acquiring the

vocabulary. Generally, the students will get difficulties in learning English at all

aspects because still lack of English vocabulary. The lack of vocabulary is caused

6

(17)

some factors from the students and the teacher. Some factors are involved in this

problem:

1. Some students think that English is difficult and complicated in

pronunciation.

2. Some students are lazy and confused in learning English vocabulary.

3. Some students have low motivation because teaching technique which used

by English teacher is bored and not interest.

C.

Limitation of the Problem

In this research, there are many components that the writer would like to

know and to find out the problem, such as the effectiveness of demonstration

technique toward the students’ vocabulary, demonstration technique can make the students active in the class, and then have high motivation in mastering the

English vocabulary. Those are impossible to talk all problems in this research; so

the writer limits the research and focus on the effectiveness of demonstration

technique toward the students’ at seventh grade students.

D.

Formulation of the Problem

The writer formulates the problem as follow: is Demonstration technique

effective to improvement of students’ vocabulary?

To answer the question, the writer would like to try applying the

demonstration as teaching technique in teaching English vocabulary at seventh

grade students of junior high school.

E.

Objective of the Problem

The objective of this research is to know whether Demonstration technique

CHAPTER II

THEORETICAL FRAMEWORK

A.

Theoretical Description

In this chapter, the writer will discuss the theoretical description. The first is

about vocabulary; there are definition of vocabulary, kinds of vocabulary, constructs

of vocabulary mastery, and how to assess vocabulary. The second is Demonstration

technique with definition of demonstration technique, the advantages of

demonstration technique in teaching, and teaching vocabulary by using demonstration

technique.

1.

Vocabulary

1.1Definition of Vocabulary

In learning a new language, first thing is the students have to master of

vocabulary. It is caused vocabulary as one of the language aspects is supposed to be

learned to be master of new language, beside other language element such as

grammar and pronunciation. The students are going to speak fluently and accurately,

write easily or understand what he/she reads, if he/she has vocabulary mastery. It is

obvious that the vocabulary is very important basic skill in learning English. Richards states, “Vocabulary is one of the most obvious components of language and one of

the first things applied linguists turned their attention to.”1

It means that vocabulary

will make the students to overcome in learning language. If the students have a good

vocabulary mastery, they can speak or listen English clearly and then write or read

the sentences in English.

According to Hornby as cited by Zaenuri says, “If we look up the meaning of

vocabulary in the dictionary, it can be defined as the total number of words that (with

1

(20)

ruler for combining them) make up a language.”2

In line by Linse states that

vocabulary is the collection of words that a person can know.3 From those definitions,

vocabulary is a set of words in language and vocabulary is a component of language

which is needed everyone in mastering language especially to foreign language. To

make the students easy in learning English, the words of vocabulary can be found in

the dictionary because there have a lot of words and meanings. Therefore, the

students understand English through the vocabulary easily.

If the students have mastered of vocabulary, it will help the students to

communicate with everyone, make the students understand all information from other

country, and vocabulary also help the students to can speak and listen English clearly

with native speaker, and then the students understand when they read the English

words from newspaper, book, magazine, etc. National Institute of Child Health and

Human Development (NICHHD) as cited by FLaRE journal points out that, “Vocabulary is stored information about the meanings and pronunciations of words

necessary for communication.”4

In the other word, the vocabulary as one of facilities

to provide and receive the oral or written information in English is needed.

From the statements of all definition above, vocabulary is a central and part of

language, because it cannot be separated from language; it is important part of

language. Vocabulary is also the knowledge toward the number of words which is

used by people to express their information or ideas as necessary to communicate,

especially in using foreign language. Moreover, vocabulary should be taught since

young students who learn English first. The other word that Vocabulary is a key

which the students can understand all about English subject such as the learner can

speak English fluently and can listen or writing or reading the English easily. For this

reason, it is very important for students to build up the skill of English words, which

is vocabulary.

1.2Kinds of Vocabulary

To know English vocabulary not only tells about the definition, but there are

several kinds of vocabulary. The students in learning vocabulary should know kinds

of vocabulary in order to the students understand the content of vocabulary. The

writer have found about it from some books and journals. The kinds of vocabulary have own meaning to describe the words. In Hiebert’s and Kamil’s book, they describe the kinds of vocabulary into some classes.

What complicates the definition of vocabulary is the fact that words come in at least two forms: oral and print. Oral vocabulary is the set of words for which we know the meanings when we speak or read orally, and Print vocabulary consists of those words for which the meaning is known when we write and read silently. And then they continue, that knowledge of words also comes in at least two forms: receptive and productive. Receptive vocabulary or recognition is set of words for which an individual can assign meanings when listening or reading. Productive vocabulary is the set of words that an individual can use when writing or speaking.5

Based on the statement above, vocabulary is distinguished into some classes such as

oral vocabulary, print vocabulary, receptive, and productive vocabulary. Oral

vocabulary is focused in speaking or reading orally and print vocabulary is focused in

writing or reading silently. Furthermore, receptive vocabulary can assign meanings

when listening or reading, and productive vocabulary is used when writing and

speaking. The writer think that the kinds of vocabulary above have the same meaning

where it is related into English skill in learning such as listening, speaking, reading,

and writing.

5

(22)

The kinds of vocabulary in FlaRe paper journal, according to International

Reading Association (IRA) explains has delineated various types of vocabulary into

listening vocabulary, speaking vocabulary, reading, writing, and sight vocabulary.

Listening vocabulary is the words needed to understand what is heard, speaking

vocabulary is the words used when speaking, reading vocabulary is the words needed

to understand what is read, writing vocabulary is the words used in writing, and sight

vocabulary is those words that can be identified without explicit decoding during

reading.6 It means that vocabulary has portions based on the purpose of skill needed

such as listening focus to heard, speaking to tell or speech, reading is needed to

understand the reading material, and writing is used in written.

Meanwhile, Aebersold and Field as cited by Zaenuri classify the kinds of

vocabulary into active and passive:7

a. Active vocabulary; it is also called as productive vocabulary, which the learner can use appropriately in speaking and writing. To use the productive vocabulary, the students must know how to pronounce it well, they must know and be able to use grammar of the target language, they also must be familiar with collocation and understand the connotation meaning of the words, because in fact it is more difficult to practice

b. Passive vocabulary; it is also called as receptive vocabulary, which that can be recognized and understood in reading or listening.

The statements above almost same with the previous statement, that active

vocabulary as same as productive vocabulary, it is focused appropriately in speaking

and writing. Then, passive vocabulary as same as receptive vocabulary, which is

recognized in reading and listening.

To sum up the statements about kinds of vocabulary that it has relate with

English skill such as listening, speaking, reading, and writing, and then there are

International Reading Association (IRA) as cited by FlaRe Paper, Evidence-based Reading Instruction: Putting the National Reading Panel Report Into Practice, (Newark, DE: International Reading Association, 2002), p. 112

7

(23)

10

passive and active. It makes the students know that the English skill have difference

vocabulary use and usage. But, those all are very useful to be learned by students in

learning foreign language, which is English.

1.3Constructs of Vocabulary Mastery

There are many teachers especially English teachers try to develop students’ vocabulary in order the students’ vocabulary improve to be better. In teaching process, the teacher usually gives activity that can improve the students’ vocabulary such as exercises at school, give homework, and give test which is related to

vocabulary materials. The purpose is the students mastering vocabulary in learning

English.

The material of vocabulary is given by teacher supposed to be adjusted what

students need to know in learning vocabulary. The teacher looks at words in more

detail that there is far more to a vocabulary item than just one meaning. Harmer

points out that for a start teacher must look at what ‘meaning’ really is:8 a) Meaning

The first thing to realize about vocabulary items is that they frequently have

more than one meaning. It is caused one word in English have more than one

meaning. Sometimes the words have meanings in relation to other words.

When we come across a word, then, and try to decipher its meanings we will

have to look at the context in which it is used. There is, synonym and

antonym include in it. As far as meaning goes, then, students need to know

about meaning in context and they need to know about sense relations.

b) Word Use

Word meaning is frequently stretched through the use of metaphor and idiom.

Word meaning is also governed by collocation, which is the words go with

each other. The people often use words only in certain social and topical

8

(24)

contexts. What we say is specified by the style and register we are in.

Therefore, the students need to recognize metaphorical language use and they

need to know how words collocate. The students also need to understand what

stylistic and topical contexts words and expressions occur in.

c) Word Formation

Words can change their shape and their grammatical value, too. Students need

to know facts about word formation and how to twist words to fit different

grammatical contexts. The students also need to know how suffixes and

prefixes work. Here, students need to know how words are spelt and how they

sound. It make the students are to be able to understand and use words in

speech.

d) Word Grammar

Here, students make a distinction between countable and uncountable nouns.

The former can be both singular and plural. There are many other areas of

grammatical behavior that students need to know about adjectives and

adverbs.

From the explanations above, this section is that knowing a word means far

more than just understanding (one of) its meanings. The teacher has to help the

students to understand in learning vocabulary to a language, because the teacher has

important role in teaching and learning process which the teacher know what students

should learn or what do students need to know. Therefore, the teacher has known

various kinds of material in teaching and learning vocabulary. Those can summarize

‘Knowing a word’ in the following way:9

Sense relations

Metaphor and Idiom

Collocation

Style and Register

Prefixes and Suffixes

1.4How to Assess Vocabulary

In teaching and learning vocabulary, English teacher almost gives many ways

in practicing the vocabulary for students in mastering vocabulary. But, those

exercises do not show that the students have master of vocabulary. Therefore, to

construct and find out the students’ vocabulary size by scoring accurately, the teacher can use a test. It is one of ways to assess the students’ vocabulary mastery which students have. According to Madsen says the goal of vocabulary tests is to measure

students’ comprehension and production of word used.10

Vocabulary test has various kinds to evaluate vocabulary mastery for students.

There are four general kinds of vocabulary tests are presented based on Madsen:11

11

MEANING

WORD USE

WORD FORMATION

(26)

a) Limited Response

It is a test which emphasize to children or beginning level students and this

activity use physical responses and visual directly. The students do not

focused to master of speaking, writing, or reading. This test can be presented

individual or group testing.

b) Multiple-choice Completion

It is a test in which a sentence and make the students focused on context clues

and sentence meaning. The test is with a missing word is presented, and then

the students choose one of four vocabulary items are given. This test has

alternate ways toward the vocabulary materials to prepare vocabulary

multiple-choice completion items, following about definition, phrase

completion (idioms/appropriateness), phrasal context (not sentence

completion), and multiple-choice cloze.

c) Multiple-choice Paraphrase

It is a test in which as sentence with the word is underlined and then the

students choose close answer or has similar meaning with the underlined

word. It is called to find the best synonym or related word. This test has

alternate forms of testing vocabulary. Following ways to write paraphrase

items, there are idiom and other phrases, phrasal context, reading passage

context, related-word identification, and unrelated-word identification.

d) Simple Completion (Words)

It is a test emphasizes word-formation which the students write in the missing

parts of words that appear in sentences. The missing parts are usually focused

on prefixes and suffixes, for example un- in untie and –ful in thankful. Here are four additional ways to prepare simple completion questions, there are

stem-first procedure (changes when suffixes are added), phrasal context

(27)

14

Those statements above, the English teacher can use those tests to measure the

comprehension of students’ vocabulary. The teacher should be able combine the vocabulary test in examining, in order the students more pay attention to understand

in learning vocabulary, especially English vocabulary. Therefore, the students are not

restricted just to multiple-choices questions.

A careful selection, or sampling, of lexical items for inclusion in a test is

generally a most exacting task. The first task for the constructor of test is to determine

the degree to which he or she wishes to concentrate on testing the students’ active or passive vocabulary. Heaton points out that it can be thought into following the four

major language skills. If the test constructor concentrates to passive vocabulary, he or

she should be taken listening and reading. Then if he or she concentrates to active

vocabulary, test constructor should be taken speaking and writing.12 There are in

testing vocabulary almost same the type of test, based on Heaton classify into some

classes such as Multiple-choice Items (A), Multiple-choice Item (B) Completion, Sets

(Associated Words), Matching Items, More Objective Items, and Completion Items.13

In here, the writer thinks the explanation of test items more clearly and simple to be

applied by English teacher in testing vocabulary.

To sum up, there are some tests items can be used by test constructor or

teacher in testing vocabulary. The test can be given through multiple-choice question,

matching item, or completion items, etc. Those tests can be chosen and used based on

the teacher’s and students’ need in testing vocabulary.

2.

Demonstration Technique

2.1Definition of Demonstration

In teaching and learning process, the teachers should make a classroom

situation become enjoy and interest for the students when the teacher conveys English

12

J. B. Heaton, Writing English Language Tests, (Nwe York: Longman Group UK Limited, 1988), p. 51

13

(28)

materials. To teach vocabulary can be showed in many different ways. There are

various ways through the teaching techniques in presenting the vocabulary; one of

them is by using demonstration technique. It is belong into the categories of

controlled technique in taxonomy of techniques. Demonstration technique is also

called role-play in processing, because the students are emphasized to play an

illustration to be showed to other people. Crookes and Chaudron as cited by Brown

states, “Role-play demonstration is selected students or teacher illustrates the

procedure (s) to be applied in the lesson segment to follow. It includes brief

illustration of language or other content to be incorporated.”14

It means that the

activity of demonstration technique is through role-play and it can be used to identify

or to illustrate the words in many situations based on the materials.

According to Petty that a demonstration is showing something (‘how’) by example and the teacher also can using in any subjects.15 In other words,

demonstration technique belong an action concept by showing something. Here, the

students doing how to do something and it can be applied in all subjects. Harmer points out, “It is often impossible explain the meaning of words and grammar either through use of realia or in pictures. Actions, in particular, are probably better

explained by mime.”16

Therefore, the writer thinks that learning vocabulary can be

presented through the action concept to explain the meaning or to introduce the new

vocabulary by using mime with the object. It means will make easy for students

understand the meaning of words that they remember when using the action or mime

in presenting.

In teaching English, the teacher can perform the material of vocabulary by

using demonstration that is each student showing the gesture or action to introduce the vocabulary. McNeill says, “Gesture in initial, Action, part highlights the other approach, which of gesture as part of the social interaction in which the person

14

H. Douglas Brown, Teaching by Principles: An Interactive Approach to Language

Pedagody, (New York: Pearson Education Inc, 2007), p. 185

15

Geoffrey Petty, Teaching Today, ( United Kingdom: Nelson Thornes Ltd, 2004), p. 173

16

(29)

16

participates. Part of the story of gesture is the role that it performs in interaction:

gesture as something engaged in our social lives.”17

It means that gesture or action is

part of approaches the social interaction and the students can perform to show or to

introduce the vocabulary. Therefore, each student can be corporate and active in

teaching and learning process in the class.

From all statements above, demonstration technique is called an action, a

mime and gesture to show or to introduce the vocabulary, which is how to do

something. It will become new experience for students in learning English vocabulary

and it will help the students remember the English words through hand or body

movement. It is also teach the students to have social interaction and corporate to

other students or other people. By teacher is it will help the teacher to present the

vocabulary clearly for students, where it is focused the students are active during

learning process. Therefore, demonstration technique is one of good ways can be

used to make easy in teaching and learning vocabulary.

2.2Advantages of Demonstration Technique in Teaching

Many times an effective demonstration is an excellent way to introduce new

moves. In order the students feel enjoy and active when learning vocabulary, the

teacher can apply by using demonstration as one of techniques in teaching and

learning process. There are advantages or strength of demonstration technique in

teaching vocabulary. Wehrli and Nyquist said that the advantages of demonstration

technique follow, “Helps people who learn well by modeling others, promotes

self-confidence, provides opportunity for targeted questions and answers, allows attention

to be focused on specific details rather than general theories.”18

It means that

demonstration is a tool that can help the English teacher in teaching vocabulary, and

18

Disadvantages/Cautions, Keys to Success, Journal of Teacher and Educational Development. 2003, p.

(30)

then help the students get self confidence and focus on specific details to the material

especially material of vocabulary.

In other opinion according to Newby, et al as cited by Journal of Purdue

University Cooperative Extension points out that advantages of demonstrations

include the students can see, hear, have experiences an actual event directly, get good

stimulus, they can present ideas and concepts clearly, and also demonstration

technique can reinforce learning for students.19 It means that demonstration technique

gives good impact toward students’ response in teaching and learning vocabulary which is students become interested. The students present their ideas clearly and

provide direct experiences. Therefore, it will make the students are interested and

active when they learn vocabulary in the class.

Cohen and Manion point out that the motivational advantages of

demonstration through simulation in learning process include:20

a. A heightened interest and excitement in learning.

b. A sustained level of freshness and novelty arising out of the dynamic nature of simulation tasks.

c. A transformation in the traditional pupil-teacher subordinate-superordinate relationship.

d. The fact that simulation is a universal behavioral mode.

The writer think that advantages of demonstration in learning process provide

a lot of changes for the students to be better such as the students are interest and

excitement, and then make students have fresh atmosphere and have super ordinate

relationship in learning process.

From statements above that demonstration technique give good effects for

students especially, which is the students are interest and enjoy in learning vocabulary

and it bring out new atmosphere in the class. Therefore, it will help the teacher in

teaching vocabulary and will have good social relationship for students from this

way.

2.3 Teaching Vocabulary by Using Demonstration Technique

Teaching vocabulary is not easy to be increased without a proper way of how

to build it up. Teaching vocabulary by using demonstration technique is one the

alternative ways to students of elementary up to university for independent learning

in or out of the class. Demonstration technique can be used by using action, gesture,

or mime in learning process. Harmer describes, “Action, in particular, is probably better explained by mime. Concepts like running or smoking are easy to present it in this way; so are ways of walking, expressions, prepositions (‘to’, ‘toward’, etc) and times (a hand jerked back over the shoulder to represent the past, for example).”21

From explanation above, the teacher can present the vocabulary by using

demonstration technique through mime, action, role play, or gesture because that is

more effective and easy to be understood for learners. But, the materials have to be

adapted when using demonstration technique such as about verb, adjectives, or nouns.

Several ways that writer does to present the vocabulary by using

demonstration based on the writer’s observation as the following:

a. Divides students for some groups with each group has five to ten students. b. The materials/objects already in the classroom

c. Materials/objects that can easily be brought such as picture card, cartoon, realia, students, etc)

d. Stationery by teachers or students, if necessary to make picture or sentences or anything before demonstrated

e. Next, demonstrate to show by actions or gestures based on the sentences or pictures.

f. After all students demonstrate, the teacher gives points or reward to the best group. In order the students have passion in learning process.

21

(32)

Other ways of teaching vocabulary through demonstration, Petty points out as

illustrate: 22

The teacher mimes a simple story. The students then take turns to describe the story as it is mimed, for example:

“He was eating a meal. He dropped some food. He called the dog. The dog ate the dropped food. He patted the dog.”

The whole class repeats the story at the end. The teacher claps once if the class is to repeat only the last line; twice if he or she wants the whole story repeated from the start, with students taking a sentence each.

The activities, teaching vocabulary by using role-play in demonstration technique

which the teacher gives a role in each of group of students, then they act out. For

example, one student in each pair could be a hotel receptionist, with their partner

playing a speaker of the target language who wants to make a booking. The students can take turns to play each role. It helps to provide scenarios such as ‘You want a quiet double room for a week’.23 It is the students practice the vocabulary based on situational in learning process which the students as actor or actress who play an

action in the classroom. The writer’s hypothesis thinks that demonstration technique in teaching and learning vocabulary is an alternative ways with teaching aids because

almost students like to do activity that interactive and fun, which is by using mime,

gesture, action, or role-play in learning process.

B.

Previous Study

Some students of university had conducted similar research about teaching

technique or teaching method in teaching vocabulary. The writer has found some

researches that related the title, which is using teaching technique. One of the

researches had written by Rachmad Setiawan with the title “The Influence of Using

Active Learning Method in Improving Students’ Vocabulary”. The purpose of this

research was to find out whether the use of active learning can develop students’

22

Geoffrey Petty, op. cit, p. 250.

23

(33)

20

vocabulary. The population of the research was the second year students of SLTP

Negeri 128 Halim Perdana Kusuma. The number of students was 80 students. The

result of the research by using active learning in learning vocabulary and from the

tests is does not have significance influence in improving students’ vocabulary.

The writer also found another research not only from students’ research of university, but the writer has found some articles and electronic books related with

the theory. Some journals as references there are by Reinhardt H. Ruhnke with the

title “Improvement of Teaching Technique through the Demonstration Lesson”, by

Rakchanok Saengpakdeejit with the title “Awareness of Vocabulary Learning

Strategies among EFL Students in Khon Kaen University”, by Y.M. Adekoya and

R.A. Olatoye with the title “Effect of Demonstration, Peer-Tutoring, and Lecture Teaching Strategies on Senior High School Students’ Achievement in an Aspect of

Agricultural Science”, and many more. Then, one of electronical books that writer

used to reference this research is by Steven J. Molinsky and Bill Bliss with the title

“Handbook of Vocabulary Teaching Strategies”. Actually, there is having some

journals and E-books as previous study to this research.

C.

Thinking Framework

Everyone really knows about vocabulary. The vocabulary can be defined as

total of number or the collection of words has meaning, which is contributed to give

information for the people. Vocabulary is also the basic skill and one of the important

factors in learning foreign language especially English, because it will help the

students more comfortable when they are reading, speaking, writing, or listening in

learning process. Therefore, vocabulary is used as facility in developing language.

Learning vocabulary not only knows the meaning of word, but the students

have to know that the vocabulary is distinguished into some classes. It seems that

vocabulary has various kinds based on the purpose such as kinds of vocabulary into

oral vocabulary and print vocabulary, or receptive and productive vocabulary, there is

(34)

vocabulary, and then many more. However, there are lots kinds of vocabulary to be

learned and to be known for students in learning process toward their English skill.

In here, the teacher has important role for students in teaching and learning

vocabulary. The teacher not only teaches and presents the vocabulary, but the teacher

should train the students through drilling in teaching vocabulary. It will make the

students remember the English vocabulary continuously and make the students

become accustomed. When the students learn the target language especially English,

they are emphasized to learn the vocabulary primary and it is very important because

it will give good impact for students in developing the foreign language. Mastery of

vocabulary influence the students to read or speak English fluently, to express

yourself effectively by using English, give self confidence with other people or a

community from other country, can help the learners when doing English assignment

or examination, etc. Therefore, that is the reasons why vocabulary is important for

students in learning English.

Those all statements above must be thought by the teacher especially English

teacher, by students, and by government of education department. It seems at some

schools in Indonesia still has the students who cannot be able in mastering English

because they have lack of the vocabulary. It is a crucial problem for teacher and

students in learning foreign language. Lack of vocabulary mastery may be caused

some factors from the students or teacher. But, the problems can be minimized

through cooperate with teachers’ role. The teacher has important role toward

students’ vocabulary in learning language, because the teacher is one of ways to help

the students increasing the students’ vocabulary. To increase the students’ vocabulary, the teacher can use teaching technique creatively. The teaching technique

that is used should be interest for students and make them active in the class when

learn vocabulary. The writer thinks, the teaching technique that will makes the

students feel interest and enjoy in learning process is by using demonstration

(35)

22

Demonstration technique emphasize toward learning visually. In learning

vocabulary through it, the students and teacher can use by mime, gesture, or action. In

one of books tell about demonstration technique by mime, action, and gesture is one

of examples of vocabulary teaching technique because the vocabulary becomes easy

if presented in this way. According to Harmer in previous explain, “Action, in particular, is probably better explained by mime. Concepts like running or smoking

are easy to present in this way; so are ways of walking, expressions, prepositions, and

times.” It is teaching vocabulary by using demonstration technique through mime,

action, or action, which is will help the teacher or students explain the vocabulary

with hand or body movement. Another resource from one of journals, demonstration

technique involves the teacher and the students showing, which is how to do

something. Demonstration can be done to be effective with both large and small

groups. The other words that teaching vocabulary through demonstration technique

will help the teacher or students to introduce new words easily and it make the

students active in the classroom. It is caused this way more effective which is the

teacher just as facilitator and the students doing social interaction in learning process,

than other conventional techniques.

To sum up based on all descriptions above, the writer assumes basically

vocabulary is knowledge of word mean and it is important part of in learning foreign

language. Mastery of vocabulary will help the students’ problem who cannot be able in English fluently. Therefore, learning vocabulary in English is very important

factor. But remember that the teacher has to make the students become interest and

make them enjoy and easy when learn English vocabulary. So, the teacher has to be

creative in using teaching technique. One of the teaching techniques is by using

demonstration technique. In here, the teacher and students can do something in

introducing the English words by mime, action, or gesture. Therefore, demonstration

(36)

It differences with other techniques that usually just emphasize students’ memorize individually in learning vocabulary.

D.

Research Hypothesis

The statistic hypothesis states:

1. Alternative Hypothesis (Ha) :

“There is a significance difference of students’ vocabulary achievement between students who are taught by demonstration technique and students

who are taught without by using demonstration technique.” 2. Null Hypothesis (Ho) :

“There is no significance difference of students’ vocabulary achievement between students who are taught by demonstration technique and students

RESEARCH METHODOLOGY

A.

Place and Time of the Research

The writer held this research at Madrasah Tsanawiyah Negeri 13 of Jakarta. It

was focused in the classroom process at seventh grade students’ of academic

2013/2014. The research was held during the second term and the writer did the

research from March 28, 2014 until April 11, 2014.

B.

Method of the Research

In collecting data, the writer used experimental research. The writer took to

use quasi-experiment in this research. There were involved two classes for the

research, namely experiment class and control class. Before starting the treatment,

the writer gave pre-test (see appendix 6) to know the students’ competence

toward their vocabulary. After the writer gave the pre-test, in first meeting the

writer taught the vocabulary by using demonstration technique in experiment

class and without using demonstration in control class. Then in last meeting, the

writer gave post-test (see appendix 8) to find out whether there was an

effectiveness using demonstration technique toward the students’ vocabulary.

Both of pre-test and post-test are multiple-choice question because in order to

take easy find out the result of the data.

C.

Population and Sample

The population of this research is seventh grade students at MTs. Negeri 13 of

Jakarta. The seventh grade students of this school consist of four classes with

about 30-38 students in each class. In selecting sample, the writer got

recommendation class from the English teacher for the sample in this research.

(38)

technique of sample by take the subject not based on the stratum, random or area

but based on the specific purpose. Commonly, this technique will take with some

consideration, such as time limit, personnel, and donation”.1

Then, the writer

divided into two classes; they are VII-F class and VII-G class. VII-F is used as

experiment class which consists of 32 students, and then VII-G is used to control

class which consists of 32 students too. The total is 64 (sixty four) students to be

sample of taken data and they are selected purposively as sample of the study.

D.

Technique of Data Collection

Collecting the data is one of the important things in this research. To make

data accurately, the writer collected the data by using the test to students’

vocabulary. The test was given to get the objectives data of students’ vocabulary

by using the treatments. The writer applied into two tests, those are pre-test and

post-test. Pre-test was given in the beginning of attending class; before doing the

treatment, and then post-test was given at the end of treatment meeting or in the

last meeting after doing the treatment.

Before administering the pre-test, the writer analyzes the validity of pre-test

instrument in order to find out whether the test is valid or good to be used. The

writer used software A ATEST to calculate the instruments’ validity. In this research, the writer implemented content validity to analyze validity of test. It

depends on a careful analysis of the language being tested and of the particular

course objective. There is strong tendency, especially multiple-choice testing, to

test only those areas of the language which lend themselves readily to testing. To

make the instrument test, the writer consulted it with English teacher, which is

about descriptive and procedure text based on English material at seventh grade.

Based on the result of instrument’s validity that was examined in SMP egeri

89 of Jakarta, it was gotten the data from 45 (forty five) questions multiple

1

(39)

26

choices that was examined there are 32 (thirty two) questions that was valid

(siginifikan/sangat signifikan) through ANATES software. Instrument that was

valid are 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 15, 18, 20, 22, 23, 24, 25, 27, 28, 30,

31, 32, 33, 36, 37, 38, 40, 41, 44, and 45. While the instrument that was not valid

(NAN/minus) are 1, 13, 16, 17, 19, 21, 26, 29, 33, 34, 39, 42, and 43.

After the writer found out the valid questions, then the writer gave pre-test.

The test is objective test which contains 30 (thirty) multiple choices questions for

students in experiment and control class. Then, the writer gave post-test; it was

given after the writer taught English vocabulary by using demonstration technique

in experiment class and without using demonstration in control class. The

post-test was also given that contains 30 (thirty) multiple choices questions to both of

class. The writer gave all questions of multiple choices based on material of

vocabulary at seventh grade and the result of pre-test and post-test were collected

and compared. The tests were used as a data, to find out the effectiveness

demonstration techniques toward the students’ vocabulary at experiment class.

E.

Technique of Data Analysis

The technique of data was conducted to analyze the validity and then pretest

and posttest of the questions. This research was focused for seventh grade

students at MTs. Negeri 13 of Jakarta. After the writer collected the data, then the

writer analyzed the result of data from pre-test and post-test and then related both

of them through the formulas of validity and reliability. The writer used the

formula that is independent sample T-test. The formula used as follow according

to Anas Sudijono:2

B.

Analysis of Data

The writer analyzes the data using T-test formula. This technique is useful to

prove statistically whether there is any significant difference between students’

vocabulary in experiment and control class. The experiment class was X variable

and the control class was Y variable.

Before calculate t-test, the writer needs to make the calculation table, to gain

[image:45.595.129.512.110.348.2]

the value of Mean, Standard Deviation and Standard Error from each variable.
