CHAPTER I
INTRODUCTION
A.        Background of the Problem
Nowadays, English is very important for our lives. This language is used world-widely in sciences, knowledge and technology as well as education, business, transaction, and other activities in the world. In the past time, Indonesian’s students started learning English at junior high school (SLTP) as a compulsory subject. The process continues to senior high school (SLTA). Nowadays, English is taught since Elementary as the local content lesson (Muatan Lokal) and even in some kindergartens, the students are introduced to English vocabulary. 
National Education Department (DIKNAS) has already run the policy and regulation for Elementary School to offer English subject for the students in the classroom. It is one of the concerns of the Indonesian government to encounter the era of information and technology.
English has been taught in Indonesia at elementary school as one of the local content subjects (Muatan Lokal). It is hoped that the students will learn and comprehend English as early as possible and can practice simple conversation. In conversation, students have to master vocabulary as many as possible, because vocabulary is very basic in teaching and learning English. According to Ministry of National Education Aminudin, the aims of teaching English at Elementary School are follows:
(1) "Student can understand vocabulary in English which are often found and used in daily context.
(2) Students can communicate simply in English"[1].
Vocabulary is very important to be mastered, so students need vocabulary which can support them to produce and use meaningful sentences because vocabulary provides organ of sentence. Harmer states that "Then it is vocabulary that provides the vital organs and flesh[2]". For that reason, the students have to develop their vocabulary and master it in order to be able to communicate with others. Vocabulary is not only sign of symbol for ideas but also a part of how to improve language skills in the target language. The more vocabulary students learn, more ideas they should have, so they can communicate by using their ideas more effectively.
In other hand teaching English to the Elementary level is not easy, because difficult to manage them, and their concentration is limited. Therefore, a good English teacher must be able to control, manage the students, make them enjoy, concentrate and focus in studying English. The teacher should choose appropriate technique to make teaching fresh and interest. Teaching technique of English teachers is very important for beginning students. Teaching techniques help teachers to create of student’s motivation in teaching and learning process.
At elementary School, most of teachers usually use conventional technique in teaching English specially vocabulary, like teacher center or total physical response (TPR), the teacher introduces some words to the students and then does the action, the students guess the meaning of  words, based on teacher actions. Teacher Centre, the teacher explain some words to the students and then explain  the meaning of the words, then the students memorize, what the teacher explained.
Based on researcher observation in SDN 13 Guguak Randah at fourth grade students on May 13th 2010, the teacher used conventional technique in teaching English. This technique  has some problems like the students feel bored and difficult to memorize the words which explained by the teacher.  the students have  less motivation in learning English because their assumption that English is difficult and  uninterested to be learned.  
On  the other hand game is an technique that helps students be more active in real life situations, pair and group work activities. It encourages students to practice the language they learn in meaningful ways. In learning process, vocabulary games are one of the activities which are requires students to be active in communicating with their classmates by their own language. Thus the question we begin to examine is, "what is the effect of using game to the students’ vocabulary mastery”?
B.   Identification of the Problem
Based on the background of the problems above, there are some of problems occured in learning process in SDN 13 Guguak Randah can be identified as follow:
1.         The students think English is difficult to be learned
2.         Teachers  use conventional technique in teaching vocabulary
3.         Students have less motivation
C.      Limitation  of the Problem
Based on identification of the problem, the researcher will use games toward students’ vocabulary mastery at the fourth year of SDN 13 Guguak Randah. This limitation is done to avoid the difficulties and using conventional method in teaching vocabulary.
D.      Formulation of the problem 
Based on the limitation of the problem above, the problem of this study is formulated as follows: “ is there the effect of using games in teaching vocabulary toward students’ vocabulary mastery at fourth year of SDN 13 Guguak Randah?”


E.       Purpose of the research
The purpose of this research is to know where the effect of using games toward students’ vocabulary mastery at fourth year of SDN 13 Guguak Randah.
F.       The significance of the research
It is hoped this research will be able to give contribution to:
1.          English teachers, they can encourage/motivate  their students’ vocabulary mastery by using games.  
2.    Students, it can help them to solve their problem in improving their vocabulary and to make them interested in materials.
3.    The researcher,to increase knowledge in teaching vocabulary  it is as the requirement to obtain the Strata One Degree in STAIN Sjech M. Djamil Djambek Bukittinggi.
G.      Definition of The Key Terms
The researcher provides several definitions of key terms bellow:
1.      Vocabulary is the collection of words that an individual knows.[3] Mean while Vocabulary mastery is the ability of the students to acquire many words and their meanings.
2.      Many Games  can be done in teaching vocabulary at elementary School, like an actor game, game cards, treasure hunt, guessing games and many others
H.      Outline of  the Research
The research consists of three chapters. In chapter I the writer presents introduction, which consists of background of the problems, identification of the problems, limitation of the problems, formulation of the problems,, purpose of the research, significance of the research, definition of key terms and outline of the research. Chapter II is about review of related literature which consist of review of the related theory, review of the related studies, conceptual framework and hypothesis. Chapter III deals which research methodology which consists of design of the research, population and sample, instrumentation, technique of data collection, and technique of data analysis.








CHAPTER II
REVIEW OF THE RELATED LITERATURE
A.    Review of  the Related Theory
1.      Vocabulary
a.      The Definition of  Vocabulary
English is a new subject to the students of Elementary School. especially is deal with vocabulary, Vocabulary is the collection of words that an individual knows.[4] It means that vocabulary is basic one which the students should know in learning a new language.
Vocabulary is very important to be mastered because vocabulary plays important role processing of communication. Students need a lot of vocabularies to communicate with others. Without having a vocabulary, students can not have meaningful sentences in communication
“Vocabulary is core component of language proficiency and provides much of the basis for how well learners speak, listen, read, and write.”[5]
It means that vocabulary mastery is important for learning a foreign language since it is a basic for students to listen, speak, read and write something well.
As a beginner in learning foreign language, many difficulties that will be found in learning process. The teachers should bring English interesting to the students, make them enjoy in  learning English and have good motivation to learn. The English teacher should be creative and  imaginative so that they have many ideas to make their students enjoy and interest in their lesson.
b.      Kinds of Vocabulary
English vocabulary is divided into two different parts: active vocabulary and passive vocabulary.
1.    Active Vocabulary
Active vocabulary is the word that you see. It means that vocabulary can be said active if we can use it for speaking and writing every day.
2.         Passive Vocabulary
Passive vocabulary is the words that you understand but do not use. It means that passive vocabulary is the words which we recognize and understand when listening or reading materials. [6]

So to learn new language the students have to increase their astive and passive vocabulary as much as posible.

c.       The Importance of Teaching Vocabulary
Learning process is a process of transformation of knowledge from the teachers to the learners. Teacher’s role in teaching learning process is to facilitate the learners to learn until they can receive and absorb the material as well as possible. Teaching is the teacher’s effort to create situation or teaching behavior in teaching process. There is an interaction between learners and environmental which includes teacher and teaching aids. It conducts to achieve the determined goal in teaching English, especially teaching English to young learners.
Teaching vocabulary is concerned with the basic technique for presenting new word. The teacher has to know the present of new words in all aspect of teaching vocabulary such as pronunciation, spelling and meaning. Teaching vocabulary can help students to understand a language. It can help them improving their ability in other skills. When students want to  be success in a language skill, they should study about the vocabulary first.
d.      Techniques and Ways in Teaching Vocabulary
Generally, as a beginner, to understand the meaning of sentence is not easy as to understand word by word. If it is not practiced often, automatically it will reduce or lose. To help students maintain the capacity of words what has been taught, games can be used as an aid.
Some techniques on teaching vocabulary can be used to explain the meaning of words, and every teacher has to determine the best technique to teach or explain the meaning of words. In determination, a teacher needs to consider whether the technique is able to improve student’s retention.
Here are some techniques for teaching vocabulary, especially new words:
1.      Say the words clearly and write it on the board.
2.      Get the class to repeat the word in chorus.
3.      Translate the word into the students’ own language.
4.      Ask the students to translate the word.
5.      Draw a picture to show what the words mean.
6.      Give an English example to show the word is used.
7.      Ask a question by using the new word.[7]

Technique is the implementation and strategies done by the teachers to the students in classroom which is suitable with the method that is used. Where as way is steps that teacher done to explain the lessons. Vocabulary mastery should be developed and planned in the teaching program. Some techniques of presenting new words can be applied by using pictures, songs, games, etc. Many techniques which could be used in teaching vocabulary:
1)      Using physical demonstration, using mime and gesture and it will be effective if we create a visual memory for the word.
2)      Using verbal explaination to involve a number of contexts, it will help the learners to find the meaning.
3)      Using the synonym of the word
4)      Using translation, pointing the objects, using visual aids, using the antonyms and using dictionaries.[8]
That techniques above can be applied by using some ways which can help the teacher to transfer the meaning of a new vocabulary. The teachers can use some ways that can be used to explain a new word into the classroom:
a)    Realia
It is one way of presenting words by bringing the things which will be explain into the classroom. Words like Postcard, pen, ball, etc. Can be obviously be presented by using this way. The teacher holds up the objects, says the words and then ask students to repeat it
b)   Picture
Picture can be used to explain the meaning of vocabulary items. The teachers can draw things on the board or bring it that can be taken from magazine pictures, wall pictures and other non-technical visual representation. It is used because  it is impossible to bring the objects that have big sizes into the classroom.
c)    Mime, action and gesture
It can use to explain the concepts like running or activities that done an action, expressions, prepositions and times.
d)   Contrast
It can be used to present the meaning of a new word by contrasting the word. Like the word of ‘empty’ can be contrasted with ‘full’, ‘cold’ with ‘hot’, etc.
e)    Enumeration
It can be used to explain the words by enumerating or listing various items.
f)    Explanation
It can be used to explain the meaning of words by explaining the context of words in conversation.
g)   Translation
Translation is a quick and easy way to present the meaning of words bui it is not without problems. In the first place it is not always easy to translate words, and in the second place, even where translation is possible, it may make a bit too easy for the students by discouraging them from interacting with the words.[9]
 Eventhough there are many techniques and ways that can teachers use, the teachers should choose the most suitable way in teaching learning process. In this research the resercher choose  picture to improve the students’vocabulary mastery.
e.       The Principles of Teaching Vocabulary
The writer has assumption to fit explanation on some principles of teaching vocabulary, there are:
1)        The teaching of vocabulary should be based on the students’ ability.
2)        The teaching of vocabulary should be suitable with student’s capability.
3)        The words are taught from easiest to the difficult.

One of the principles that had been found useful in all methodological decisions is the principles of time effectiveness. The key in all, vocabulary teaching is to keep motivation high while encouraging students to develop strategies that they can continue to use once they leave the classroom.
According to the assumption above, explains that to know a word in a language as well as the native speakers know it needs the ability to:


Recognize it in its spoken or written form.
1.      Recall it will.
2.      Relate it to an appropriate object or concept.
3.      Use it in the appropriate grammatical form.
4.      In speech, pronounce it in a recognizable way.
5.      In writing spell it correctly
6.      Use it with the words it correctly goes with i.e. in the correct collocation.
7.      Use it at the appropriate level of formality.
8.      Aware of its connotations and associations.[10]

f.        Teaching children
Teaching English to young learner is really different from teaching English to teenagers or adult. Teaching English to young learners is the basic foundation on learning something and it will be continued in adolescent age.
Moreover, Wilkins explains that “the young children find the task of learning foreign language easier than older children”.[11] They are able to reproduce sounds in imitation with little difficulty. Activities like imitation and repetition which feel bore to be an inevitable part of language teaching, often a source of pleasure to the young children whereas in the older learner they do little more than cause irritation. The primary age children are usually lack of self-consciousness of the older learner and all together more prepared to submit to the norms of a new language and to perform in it without feeling at risk of making a fool of him self.
For success teaching children the second language requires specific skills and intuition that different with teaching adult. Brown divided five categories that help or give teachers some practical approach in teaching children:
1.    Intellectual development.
Since children are still in an intellectual development, the teachers need to remember their limitation. In teaching children, the teacher should consider the following:
a.    Don’t explain the grammar using term like ‘Simple present’ or ‘Relative clause’. It needs to be noted that using the language terms in the explanation will only teach the children about the  language but not the language it self.
b.    Rules stated in abstract terms should be avoided. For example, ‘To a statement into a question, you should add a do or does’.
c.    Certain more difficult concept requires more repetition. It may be necessary to get the brain and the ear to cooperate.
2.    Attention span
According to dictionary attention span means the length of time for the action of turning one’s mind to something. The short attention span comes up when the teacher present stuff that to them is boring, useless or too difficult.
3.    Sensory input
Children need to have all five senses stimulated. The activities in the classroom should strive to go well beyond the visual and auditory modes, for instance: touch your nose, touch your head, close your eyes, etc
4.  Affective factor
Children are often innovative in language forms but still have a great many inhibition. The teacher should need to help them to laugh with each other at various mistakes that they all make, be patient and supportive to build self-esteem of children, and give them plenty of opportunities for trying things out.
5.  Authentic, meaningful language.
Story lines, familiar situation and characters, real-life conversation, meaningful purpose in using language will improve attention and retention of children.”[12]

In this case teacher should create the real situation, which is near by students environment in teaching english so that is easy to understand by students.
 2.  Games
Learning a foreign language is a hard work, one must make an effort to understand and to repeat words accurately. English teacher has to have a good plan to motivate the children, to enrich vocabulary mastery by using drills and exercise. But, in reality the children fell bored with these techniques because the process is monotonous. If  teacher still using these techniques, the children cannot improve their English to solve this problem, the English teacher has to create his teaching with certain technique that enables him to avoid the technique which is boring.
Since English subject in elementary school is still new, English teacher needs to find out good techniques that can make the children interested in learning English. In this case Julia Khan states:
“Children play and children want to play. Children learn through playing. In playing together, children interact and in interacting they develop language skills. Games provide context for play, reasons for playing and routine for playing.”[13]
Through games children are stimulated to know more vocabulary in order to win the game. If they do not understand the meaning of the words, even only a word, they will loose a chance. By this technique the children will learn as many words as they can. The teacher has to plan some activities that make their children enjoy learning the foreign language by using games. This technique makes teaching learning foreign language more creative, active, relaxed and fun.
a.    The Meaning of Games
What expected by every language teacher in the whole world is making the transfer of knowledge become easier and more comfortable for the students by using any kinds of teaching aids, including games.
In oxford advance learner’s dictionary of current English, game is form of play, especially with rules, e.g. tennis, football cards.[14]
According to Jeremy Harmer, “games are a vital part of a teacher’s equipment, not only for the language practice they provide, but also for the therapeutic effect they have. They can be used at any stage of a class to provide an amusing and challenging respite from other classroom activity about their English class”.[15] Stephen Mark Silvers said that:
“Most of you who have experimented with language games as a teaching device will be, I am sure, as enthusiastic about their use as I am. Unfortunately, many teachers still feel that game is only for a short time, to give a class break from the monotony of drilling, and some teacher consider games merely frivolous activity”[16]
Sandra J.Savignon has three reasons why games have to be used in learning foreign language, they are:
a.    The very structure of games provides an opportunity for learners to practice vocabulary and grammar, specific functions, and other language art skills. The task orientation of the games requires that the students “use rather than merely practice language for real and immediate communicative goals” on the other hands require constant, meaningful interaction among the players.
b.    They created relaxed atmosphere. This lower the anxiety level or “effective filter” that often keeps students from learning. Games accomplish this in two ways. First, games focus the learners attention on the immediate goal, that is, succeeding at the same itself, rather than in the responsibility of language learning (Stoic, 182). Second, whether the game is competitive or not, it requires cooperation. This contributes to the development of a sense group that led in turn to feeling of support and security among the group members. As the result, the learners are less anxious and more open and able to communicate.
c.    Games offer strategy for dealing with problems that may arise from code implication. Teacher to provide communication at a level the learners can understand often uses code implication.[17]

And according to Rebecca L. Oxford and David Crookal  game can encourage good strategy in learning foreign language. They are:
a.    Games embody the communicative approach; they provide active involvement of the whole person (intellectual, physical, social and emotional).
b.    Games change the roles and relations of learners to take more active role in their own learning process. This has two effects:
1)   It gives learners much more opportunity to communicate in the language.
2)   It places more responsibility on learning to direct their own learning.
3)   Game provide language quantities of input, which can be understood because of meaningful, and engaging context f the activity.
4)   Game allows attention to be given to language form as well as to content.
5)   Game has additional effective advantages, such as education of anxiety increase in positive feelings and improve self confidence.
6)   Game can make the participant encouraged to communicative even when their knowledge and competence in the language is less than they would wish.
7)   Games have the learners to identify more closely with the target culture.
8)   Game encourages adolescents and adult to once a gain. Play with symbols.[18]

From the explanation above, we know that game is form of play and can be used as a vital part of a teacher’s equipment in English teaching.

b.   The sample of Games in teaching vocabulary
Even though many games can be used in teaching vocabulary, that is depend on the material for example:
1.    An actor game
Lee explained game is an enjoyable activity which has important virtues. Games banish boredom and give stimulation  and entertainment to the learner. If talking about game, Rini and Ayu  propose one kind of a game namely An Actor Game, “An Actor Game is a movement game that can ask the students to guess the meaning of the words based on acting of an actor.”[19]
This game can be done in elementary school, age 6-12 years old. By applying An Actor game, children are physically active in the class and increase the student’s motivation in learning English especially in learning vocabulary.
Beside that, by using this game, children easier in learning vocabulary by looking  to what an actor acted in several time and doing an action too. Students can enlarge their vocabulary easily, such as; When the teacher writes “singing” on the whiteboard and the teacher sing a song directly, so the students will understand the meaning of “singing” by looking what the teacher did.
In An Actor Game, the children should compete in guessing the meaning of the word acted by an actor. The student who can guess the meaning of the words many times, so she/he will be the winner in that game.
An Actor Game can be used by the teacher in the fourth years, fifth years, and also in the sixth years, especialy in listening copetency for example: standar kompetensi “merespon dengan melakukan tindakan sesuai dengan instruksisecara berterima dalam kontek kelas dalam berbagai permainan, merespon indikasi sederhana secara verbal,  bercakap-cakap untuk meminta dan memberi jasa”, and etc.



2.    Game card
Most of students like play card, so the card cand be used to motivate students in teaching learning especialy in teaching vocabulary this game cosist of pictures and words, the students should match the picture and word corecly to be the winner. It will grow up students vocabulary mastery. That games can be aply in many material like clothes, fruits, colour animal and many others.
a.    The rule of games
Lay the cards face down on the table or on the floor, the cards can be place in row or randomly,each player in turn, turn over two cards, if the cards match the player keeps them and is awarded one point, then continue to the next player’s turn, if the card do not match the player returns them to the same place and forfeits their turn to the next player, each set of cards is enough for six player, point more sets of each level for more player, laminate the card for many years of use.
b.   Level and language learning
The cards only have pictures on them to make them esier to remember. Show each the card as if they were flashcards to the students state the word assosciated with the cards, ask the students to repeat the word. Play for fun but encourage the player to say the word associated with each picture on the card, if the students not sure of the word ask the others or tell the students the word.
 One card has the picture and the other matching picture has the word, show the picture card as if flash card and ask the students to repeate the word, repeat with the word card, if the student flips the word card the teacher can help them  with the word  in the first few round.
Both card have only the words, this game should be played after the students are familiar with the level before, show the cards as if flash card and ask responses, devide the students in teams, each with captain, the captain flips the card and must read the word, the team may help, the team with the most fairs at the and win, This game sugested by advanced teacher trining inc    
3.    Game Star
Providing explicit and direct instruction is one sure way to help students increase their vocabularies. “The STAR  model of Select, Teach, Activate, and Revisit provides a framework for teachers as they plan vocabulary instruction.”[20]
a.    Select
1)   Choose appropriate content words.
2)   Focus on words essential to understanding of the text.
3)   Draw a story or text map. Using the map as the basis, select four to six words fundamental to retelling or summarizing the text.
4)   Look for other important words that students are likely to encounter in additional readings, even though these words may not be essential to this particular text.
b.    Teach
1)   Consider the processes you will use before, during, and after reading.
2)   Before assigning the reading, make sure you access prior knowledge and bring to the forefront concepts that will not be clearly explained in the text.
3)   Use definitional, contextual, and usage information when teaching vocabulary. For example, present the word in context, discuss possible meanings, ask for a definition (provide one if students are unable to provide an accurate definition), ask students to use the words in a personal way.
c.    Activate
1)   This step focuses on the work you want students to do in order to gain understanding.
2)   Use writing assignments and other activities to make sure students repeatedly hear, read, write, and use the targeted words.
3)   Give students the opportunity to connect new words with other words they already know (word maps or synonym webs).
4)   Have students act out words or demonstrate meaning.
4.    Guessing Games
Guessing games can be painless ways to develop or reinforce any number of concepts. “Guess What I am” or “Guess Who I am” for example, can be used to teach about animals, professions, or people in different age groups (baby, child, teenagers, young adult, middle-age adult, elderly person). “Guess What I’m doing” can be used to teach recognition in the target language of activities such as taking a bath, go finishing, doing homework, and so forth.[21]  Various sources for game ideas are mentioned, but teachers are reminded that one of the best sources is the students themselves.
c.    The Ways of Using games in Teaching Process
Teachers can apply the games in their teaching process by using several activities that it can help their students to master a news vocabulary. There are several activities that teachers can use to improve the student’s vocabulary.
1)   Study vocabulary in context. Teachers should inform the students what the context of the lesson that will discuss so that the students did not misunderstanding about the meaning of the words.
2)   Using the suitable media to identify vocabulary words. The teachers can stimulate their students’ understanding by guessing the word by using media, likes: pictures, real objects, songs, card, and dictionaries.
3)   Using the creative tests to evaluate the student’s ability. The teacher should use the suitable tests that will be given to their students. They can use games or cross word puzzle and many kind of tests that make the students be interest and are not bored to finished the tests.
4)   Ask the students to use the words in their daily activities. It can improve their ability in memorizing the words. But in this case, their environment should support them in learning process.
In using game , there are some  simple activities that can be done. Firstly, prepare a game to be discussed, then explain rule of games to the students and ask them to play the game. Secondly, repeat the activity until all of the students able to play it using their own words. Thirdly, the teacher would repeat the word in the correct pronunciation if the students made mistakes in pronouncing their words. Fourthly, demonstrate the game with random and ask the students to name of this, it done to measure their understanding the words.
B.     Review of the Related Studies
This research is not the first research that discuss about game. There were some studies had generally brought positive effect of using games that had been conducted by some researches, they are;
Noris nenny maullida, “Improving student motivation in learning English by using  modified guessing games” (study of the sixth year student of SDN 05 Batipuh)  said that the percentage of students motivation in learning English by using modified guessing games technique in this study was improved.  it’s conclude that teaching vocabulary by using modified guessing games technique could improve student motivation in learning vocabulary 1st 2010 until 29th 2010[22]
Diah Sri Lestari 2007 Technique For Motivating  The Student In Learning English.  She found that indirect motivation technique is more interesting student Learning English The effectiveness of teaching vocabulary by using word puzzle (study at the fourth grade student of SDN 5 Baum ) said that teaching vocabulary by using game word puzzle was more effective than that by Using Total Physical Response. 2010[23]



C.    Conceptual Framework
Teaching English to the Elementary level is not easy, because it is difficult to manage  students, and their concentrate are limited. Therefore, a good English teacher must be able to control, manage the students, make them enjoy, concentrate and be interested in studying English.
The teacher should choose appropriate methods and techniques to make teaching be fresh and interesting. Teaching technique  is very important for beginning students. Teaching techniques can help teachers to create of  motivation  and  interested of students in English studying. Thus, an English teacher should find an interesting technique in dealing with this situation. One of the techniques that can be used games. In teaching vocabulary to make the students enjoyable. This research is intended to see the effect of using games technique  on student to mastery of vocabulary. The research can be shown in a diagram as follows.

The scheme above shows that the students are divided into two classes, they are experimental and control class. The experiment class students are taught by using games and control class are taught by using conventional method, such as total physical response. In addition, the experiment and control class students are given pre and post test at the same time.
At the end of study, the researcher will see the effect of using game which is given at experiment class. The result of test of the two classes will be compared to see the effect of using the games
D.    HYPOTHESIS
Based on the background, formulation and purposes of the problem above, the hypothesis of this research are:
Ha: There is effect of using games in improving students’ vocabulary.
Ho: There is no effect of using game in improving students’ vocabulary.
In conclusion, Ha means there is effect of using games in improving students’ vocabulary of fourth grade students of SDN 13 Guguak Randah. On the other hands, H0 means there is no effect of using games in improving students’ vocabulary fourth grade students of SDN 13 Guguak Randah.







CHAPTER III
RESEARCH METHODOLOGY

A.  Research Design
The design of this research is true experimental research by using quantitative approach because the researcher will compare between the using of  games and conventional technique. In this case, there are two groups involved. One group is the experimental group, and another is control group. The experimental group will get treatment, taught by using games, while another  use conventional technique. Related to experimental and control, Gay states, ”The experimental group usually gets new treatment or treatment under investigation, while the control group gets different treatment or treated like usual”.[24] Moreover, he adds that the control group is needed to know whether the new treatment or treatment under investigation is more effective than the usual one.
Experimental research has both pre- and post-test. There test has experimental and control classes. In this research the writer will use the  existing classes. The class A will use games in teaching vocabulary and the class B still use (conventional technique). After giving treatment to experimental class, the two classes will be   given pre- and post-test.
Gay says that an experimental research involves two variables; the independent variable and the dependent variable.[25] In this research, the independent variable is the games and the dependent variable is the students’ vocabulary mastery. The design can be shown as follows:
Name
Pre-test
Treatment
Post-test
Experimental Group
T1E
X
T2E
Control Group
T1C
-
T2C
            Where:
T1E      = the pre-test for the experimental group
T2E      = the post-test for the experimental group
X         = the treatment that is given to the experimental group by using games
T1C      = the pre-test for the control group
T2C      = the post-test for the control group
B.  Population and Sample

The population in this research is all of fourth grade students in SDN 13 Guguak Randah, consist of two classes. According to Gay, ”Population is the group of interest to the research”.[26] The population is 46 students. Each of classes consists of twenty three students.



2.    Sample
Sample is simply a subset of the population. In order to take the sample, the writer will use total sampling technique. As stated by suharsimi arikunto, If the amount of population is less than a hundred, so it is better to take all of the population as the sample of the research in order to make accurate generalization. Thus, one of two classes is chosen to be control class and one class to be experimental class.
To choose the experiment and control class between these two classes, the researcher will follow the steps below:
a.    Collect the mark of  fourth  grade student mid test in SDN 13 Guguak Randah 2011/2012 academic years.
b.    Test the normality of the data.
The purpose of testing the normality of the data is to know whether the data spreads out normally or not. Normality of the data is tested by using Liliefors test. It can be done in these steps below:
1)   Arrange the data from the lower to the higher one
2)   Find the mean score (x) and the standard deviation (s)
3)   Find the score of Zi  by using the formula: Zi  =  Xi – x   s
4)   Find the score of P (Zi) by consulting the score of Zi with Z table
5)   Find S (Zi)
6)   Find the absolute score of P (Zi) – S (Zi)
7)   Determine the higher score of absolute mark P (Zi) – S (Zi). It is named as Lo ( Liliefors)
8)   Test the Lo score with Liliefors table with the certain degree of freedom (α): 0,01 or 0,05
9)   Take the conclusion, if the Ltab > Lo, it can be concluded that the data is distributed normally with the degree of freedom in (α) 5 %.[27]
c.    Test the homogeneity of the data
The purpose of homogeneity test is to know whether the population is homogeneous or not. This test is done by using F test. The homogeneity test by using F test is done by following steps:
The homogeneity test by using F test was done by following steps:
1)   Use the formula :
       Fhit = S12       
                            S22       
2)   Consult with table F which α (0.05)
Ftab right = fα (V1,V2)
          Ftab left   =         1
                          Fα (V2,V1)
3)      If the range of score of Fhit located between Ftab Left and Ftab Right, it can be concluded that both of the classes are homogeny.[28]


C.  Instrumentation
In this research the instrument that will be used is the tests of students’ vocabulary mastery by using multiple choice test. There are two tests that will be used, pretest and posttest. The test is set based on the goal of teaching and learning that will be achieved. Pretest is used to know the students’ vocabulary at the beginning and posttest is used to know the development of the students’ vocabulary in the end after given the treatment.
The test is made by considering the validity and reliability of the test. The validity is concerned with what a test measures and for whom it is appropriate. The reliability refers to the consistency with which a test measures whatever it measures. Here are the brief explanation about validity and reliability of test.
1.    Validity
Gay says “Validity is the degree to which a test measures what it is supposed to measures”.[29] The validity of the test depends on particular purpose and particular group. In other word, the test is valid if it is appropriate for what and for whom.
There are content validity and construct validity; content validity is the degree to which a test measures an intended content area. Construct validity is the degree to which a test measures and intended hypothetical construct. A construct is a non observable trait such as speaking ability. So, in oral test, the construct validity cannot be seen because it depends on students’ performance.     

The researcher gives try out to another elementary school. To measure the validity of the test, the researcher uses product moment with the deviation formula.
                rxy  =

             Where :
rxy     =    Correlation coefficient between X variable and Y variable, these        two variables are correlated
N      = Number of items
ΣXY =   Multiplying the number of x with y
X2     =   Square of X
Y2     =    Square of Y
2.    Reliability
   Reliability refers to the consistency of a measure. A test is considered reliable if we get the same result repeatedly. Technically, reliability shows the extent to which test scores are free from errors of measurement. Gay says that reliability is the degree to which a test consistently measures whatever it measure.[30]
The reliability of items use K-R 20 suggested by Arikunto as follows:

           
           



Where :
          rii            = Reliability
          n = Number of items
          p = Proportions of the number of students answer correctly
          q = Proportions of the number of students answer incorrectly (q=1-p)
              = Total number of p times to q
          S            = Standard-deviation
            General description of coefficient correlation as follows:
   0.80 < rii 1.00              : Very high
   0.60 < rii 0.80              : High
   0.40 < rii 0.60              : Moderate
   0.20 < rii 0.40              : Low
   0.00 < rii 0.20              : Very low

3.    Item Difficulty
            The researcher uses formula suggested by Arikunto to know item difficulty which is presented as follows.[31]
P = B 
       S
Where:
P          = Item difficulty
B         = The number of students answer correctly
JS        = The number of students who are tested
The classification of item difficulty is as follow:
Item with P 0.00 until 0.30 is difficult
Item with P 0.30 until 0.70 is moderate
Item with P 0.70 until 1.00 is easy
4.        Item Discrimination
            Item discrimination is the ability of item to differenciate between student who has high achievement and student who has low achievement. For that, the researcher uses formula to determine the item discrimination suggested by Arikunto which are presented as follows.[32]
                D = BA _ BB
                   JA     JB


            Where:
            D         = Item Discrimination
            BA      = The number of high score students who answer correctly
            JA        = The number of high score students
            BB       = The number of low score students who answer correctly
            JB        = The number of low score students
            Arikunto takes 27 % students of the highest score as JA and 27 % of the lowest score as JB.
            The classification of item discrimination is as follows:
            D: 0.00 – 0.20 : Poor
            D: 0.20 – 0.40 : Satisfactory
            D: 0.40 – 0.70 : Good
            D: 0.70 – 1.00 : Excellent      
D. Technique of the Data Collection
In line with the research design above, the data is taken from the students’ vocabulary tests. The pretest is given to the experiment and the control class before given the treatment. The pretest is used to know the students’ vocabulary at the beginning. The researcher takes the students’ vocabulary performance scores based on scoring and measuring guidance for vocabulary test.
The posttest is given to the experiment and the control class after giving the treatment. The posttest is used to know the development of the students’ vocabulary at the end. The researcher takes the students’ vocabulary scores based on scoring and measuring guidance for vocabulary test. The scores of the students on these tests are collected in order to be used as the data.
E.   Technique of the Data Analysis
This research will use the t – test in analyzing the data. There will be four formulas that use to analyze the data in this research. The first will use to find the average score of each group. The second will be the sum of square. The third calculate standard deviation. The last calculate t-test formulate. Gay says that it uses to see significance of the different mean square between the two groups.[33]
The formulas are as follows:
1.      
2.    SS =
3.    SD =
4.   
Where:
t= the value of t-calculated (observed)
= Mean Score of the Experiment Class
= Mean Score of the Control Class
SS = The sum of squares
SS1= The Sums of squares of experiment class
SS2 = The Sums of Squares of Control Class
N  = Number of sample
 = Number of Experiment Class
= Number Of Control Class
SD = Standard deviation
To find out whether the value of t obtained indicates a significant difference between mean score of two groups, it will be compared to the value of t in the table at the degree of freedom α = 0,05. The condition is the descriptive hypothesis (Ha) will be accepted if – ta < t hit < t½a. It means that the descriptive hypotheses (Ha) will be accepted if t obtained locates between – t table and + t table.
