    CHAPTER I

    INTRODUCTION

    A. Background of Study

    Vocabulary is one of language components studied by students at all

    level of schools in Indonesia. It is impossible to be successful English

    learners without mastering the English vocabulary. Vocabulary is a central

    aspect of language and of critical importance of typical language. Without

    having sufficient vocabulary, people can not communicate effectively or

    express his ideas in both oral and written form. To support the speakers

    interaction in communication, vocabulary becomes important because it can

    be used as basic foundation to construct a word into a good se!uence of

    sentence.

    Vocabulary is one of important component in English, so learners

    need to master it well. The learner should comprehend and have high

    confident to use it in front of speaker especially when the learner

    communicate. Vocabulary has important role to use as tool of

    communication. "ince vocabulary is very important for the student who

    study English, higher interest should be given to it.

    #t $Ts% &ute the student have potential to speak or write but the

    student have a problem to support their potential that is the student still low

    on vocabulary skill, it is because the students do not know how the exactly

    way to learn vocabulary and ac!uire it.

    "o to solve the problem the researcher use the metacognive strategy

    in this research to increase the students vocabulary skill. This strategy have

    advantage in teaching vocabulary, that is the student can be control their

    develops higher learning and problem solving skill. "pecifically, this

    research would like to finding out the effect of using metacognitive strategy

    toward students vocabulary achievement at $Ts% &ute.

    E. Scope of t$e "tudy

    )The research is limited to eight grade students of $Ts% &ute, and

    Vocabulary achievement using metacognitive strategy. There are two

    variables in this study0 they are independent variable and dependent

    variable. Independent variable is metacognitive strategy and dependent

    variable is students vocabulary achievement.

    a. $etacognitive strategy is thinking about thinking. #s #nderson states

    the use of metacognitive strategies ignites one1s thinking and can lead to

    higher learning and better performance 2#nderson, 33( -4. Its mean

    using metacognitive strategy the learner will be more think about the

    way how to learn until the learner get the exactly way to learn, so the

    learner will be more easy to learn.

    b. Vocabularry is a core component of language proficiency and provides

    much of the basis for how well learner speaks, listen, read, and write

    #ccording Thornbury 233;(-:4 without grammar very little

    can be conveyed, without vocabulary nothing can be conveyed. This is

    how linguist ?avid Wilkins summed up the importance of vocabulary

    learning. =is view is echoed in this advice to students from a recent

    course book 2?eller = and =ocking ?, Innovation, CT/4( )if you spend

    most of your time studying grammar, your English will not improve

    very much. Dou will see most improvement if you learn more words

    and expression. Dou can say very little with grammar, but you can say

    almost anything with words.

    f all the language skills, it is widely acknowledged that

    vocabulary is a very important part in English language learning, and

    that no one can communicate in any meaningful way without

    vocabulary. +owen et al. 2-786( :4 and $c@arthy 2-773( iix in

    "iriwan $ayuree, 33;4 indicate that the single, biggest component of

    any language course is vocabulary. This is consistent with %ation

    2-773( 4 who affirms that learners also see vocabulary as being a very,

    if not the most, important element in language learning. Cearners feel

    that many of their difficulties, in both receptive and productive

    language use, result from the lack of vocabulary knowledge. &ita

    5eceptive or recognition, vocabulary is that set of words for

    which an individual can assign meanings when listening or

    reading. There are words that are often less well known to students

    and less fre!uent in use. Individual may able assign some short of

    meaning to them, ever though they may not know the full subtleties

    of the distinction. Typically, there are also words that individuals

    do not use spontaneously. =owever, when individuals encounter

    these words, they recogniFe them, even if imperfectly 2=iebert G

    &amil, 336( -A4.

    b. /roductive vocabulary

    /roductive vocabulary is the set of words that an individual

    can use when writing or speaking. They are words that are well H

    known, familiar, and used fre!uently 2=iebert G &amil,336( -A4.

    B. Teac$#ng 'ocau!ary

    Vocabulary is very important for second language learners0 only with

    sufficient vocabulary learners can effectively express their ideas both in oral

    and written form. Thus they should have a good idea of how to expand their

    vocabulary so that they can improve their interest in leaning the language.

    Canguage teachers, therefore, should posses considerable knowledge on how

    to manage an interesting classroom so that the learners can gain a great

    success in their vocabulary learning.

    Teaching vocabulary plays an important role in language ac!uisition

    because the mastery of vocabulary will help students to master all the

    language skills0 speaking0 listening0 writing0 and reading. The vocabulary will

    make the students practice life and will strengthen belief that English can be

    6

    used to express the same ideas or feeling they express in their native

    language.

    'urthermore2'inochiaro, -7;A(:8 in "ofika @handra %ilawati, 3384 in

    teaching vocabulary the teacher can introduce the list of vocabulary that is

    taken from the book. The teacher uses and adds other vocabulary which is

    relevant to the students. Teacher needs a good knowledge on their teaching

    materials. When they have to teach the students about vocabulary, teachers

    should know the general knowledge of vocabulary, words and also the

    meaning. The words or vocabulary can be spoken and written.

    Wallace 2-78(3; in "ofika @handra %ilawati, 3384 explainsteaching

    vocabulary should consider as follows(

    a. #ims

    The aim of teaching vocabulary is to make the teacher easy to

    formulate thematerials, which will be taught to the students.

    b. uantity

    The teacher has to decide the number of vocabulary items to be

    learned. Thelearners will get confuse or discouraged if they get many new

    words.Therefore, the teacher should select new words, which can easy to

    understandby the learners.

    c. %eed

    In teaching vocabulary, the teacher has to choose the words really

    needed bythe students in communication.

    d. 're!uent exposure and repetition

    7

  • 7/25/2019 Proposal Abenk

    8/29

    're!uent exposure and repetition here means that the teacher should

    givemuch practice on repetition so that the students master the target

    words well.They also give opportunity to the students to use words in

    writing orspeaking.

    e. $eaningful presentation

    In teaching vocabulary the teacher should present target words in such

    a way. That the meaning of the target words is perfectly clear and

    unambiguous.

    f. "ituation and presentation

    The teachers tell the students that they have to use the words

    appropriately.The use of words depends on the situation in which they are

    used anddepends on the person to whom they are speaking. 'rom the

    expalnation above the researcher conclude that the teachers must know the

    different kinds of vocabulary. In addition, understanding the above factors

    is very important for the teacher before teaching vocabulary to elementary

    school.

    In teaching vocabulary, a teacher also should be aware on some

    principles. =armer 2-77-( -6A4 states )ne of the problems of teaching

    vocabulary is how to select what words to teach. 'urthermore, he says

    )other criteria which are rather more scientific have been used0 two of the

    more important are fre!uency and coverage.

    +ased on the statements, in teaching vocabulary, a teacher is expected

    to select words which are fre!uently used by the speakers of the language

    and are covered in many other words.

    8

  • 7/25/2019 Proposal Abenk

    9/29

    +. Ind#cator" of 'ocau!ary

    #ccording to Thornbury 233;( ;4 there are four indicators of

    vocabulary follow as(

    a. /ronunciation5esearch shows that words that are difficult to pronounce are

    more difficult to learn. /otentially difficult words will typically be

    those that contain sounds that unfamiliar to same groups of learners

    such as 5egular and Corry for >apanese speakers. $any learners find

    that words with clusters of consonants, such as strength or scrip or

    breakfast, are also problematic.. "pelling

    "ound H spelling mismatches are likely to be the coused of

    errors, either of pronunciation or of spelling, and can contribute to a

    words difficulty. While most English spelling is fairly law H abiding,

    there are also some glaring irregularities. Words that contain silent

    letters are particularly problematic( foreign, listen, headache,

    climbing, bored, honest, cupboard, muscle, etc.

    c. $eaning

    When two words overlap in meaning, learners are likely to

    confuse them. $ake and here are a case in points( you make breakfast

    an make an appointment, but you the housework and do a

    !uestionnaire. Words with multiple meaning, such as since and still. It

    also can be troublefor some learners. =eaving learned one meaning of

    the word, they may be reluctant to accepts a second, totally different

    meaning. Jnfamiliar concepts may make a word difficult to learn.

    Thus, culture specific items such as word and expressions associated

    with the game cricket 2a sticky wicket, a hat trick, a good innings4

    9

  • 7/25/2019 Proposal Abenk

    10/29

    will seem fairly opa!ue to most learners and are unlikely to be easily

    learned.

    d. Jsing word

    The letter is the most authentic, but even that talk is

    constrained by a contrived situation in which the test taker, usually in

    matter of second has to come up with an appropriate sentence, which

    may or may not indicate that the test taker )known the word.

    +ased on the explanations above, it can concluded that

    vocabulary is a list of words or total numbers of words that make up

    language and often prhases usually arranged alphabetically and

    defined or translated as a lexicon or glossary, that it come in at least

    two forms( oral and written and one of the important elements in

    language learning besides sound, structure and grammar in which

    consists of some indicators such as pronunciation, spelling, meaning

    and how to using the word. Vocabulary can be defined as the stock of

    words used by person, class or profession and it can make the basic

    words in English necessary for communication with another persons.

    ,. Te"t#ng 'ocau!ary

    =arold 2-78:(-4 states the purpose of vocabulary tests is to

    measure the comprehensionand production of words.

    To know directly the progress of vocabulary teaching or

    thestudents achievements, the writer should test the students. The writer

    inthis section present only with thedescription of what to test and thetypes

    of test that could be developed.

    =arold 2-78:(-4 states there are four general kinds of vocabulary

    test. They are (

    10

  • 7/25/2019 Proposal Abenk

    11/29

    a. Cimited 5esponse.These test items re!uire either a simple physical

    action like pointing at something or a very simple verbal answer such

    as KyesK or Kno.K .In testing children and beginningBlevel adults, we often use

    directed physical responsesand visuals.We do this to avoid language

    skillsthat have not been mastered yet. 'or these tests,students don1t

    have to knowhow to read or write. In fact, they don1t even have to

    know how to speak.

    b. $ultipleBchoice completion. It is a test in which a sentence with a

    missing word is presented0 students choose one of four vocabulary

    items given to complete the sentence.

    # good vocabulary test type for students who can read in the

    foreign language is multipleBchoice completion. It makes the student

    depend on context clues and sentence meaning. This kind of item is

    constructed by deleting a word from a sentence.

    c. $ultiplechoice paraphrase. It is a test in which a sentence with one

    word underlined is given. "tudents choose which of four words is the

    closest in meaning to the underlined item.

    $ultipleBchoice paraphrase tests of vocabulary items offer much

    of the same advantage that multipleBchoice completion tests do, and

    the contexts are much easier to prepare. Jnderstanding is checked by

    the student1s having to choose the best synonym or paraphrase of the

    vocabulary item. # sentence context is still used. =owever, choosing

    the right word depends more on knowing the key vocabulary item

    11

  • 7/25/2019 Proposal Abenk

    12/29

    than on finding meaning in the sentence. In 1fact, the context may

    simply show that the item is a noun.

    d. "imple completion 2words4 has students write in the missing part of

    words that appear in sentences.

    WordBformation items re!uire students to fill in missing parts of

    words that appear in sentences. These missing parts are usually

    prefixes and suffixes, for example, the unB in untie or the Bful in

    thankful. # related task is to use words like the following in a sentence

    and have students supply missing syllables of any kind, such as the

    reiB in relative or the Bate in deliberate. We can see, then, that there is a

    different emphasis in simpleBcompletion tests than in those we have

    words in a sentence context, or words in whole context.

    In this research, the researcher will be applying the one of

    mnemonics strategies that is linkword or keyword method also known as

    the keyword mnemonic. The researcher use this method in this research

    because this methodit is one of the most powerful methods for learning

    the meaning of foreign language vocabulary, and can also be used for

    In learning English vocabulary for the second language and foreign

    language teachers and students will find out many difficulties and

    problems. The researcher found many problems based on the teaching

    practice done by the researcher in the school some students lacked in

    vocabulary and the students still not understand if the teacher asked them

    in English. "tudents did not know what they would say to respond the

    teacher because the students lack vocabulary. "tudents were confused to

    choose the words to make sentences. To solve these problems, the

    researcher must have a good method in teaching English vocabulary for

    the students.

    ne of the teaching strategies in teaching English vocabulary is

    using $etacognitive "trategy. $etacognitive "trategy is able to help the

    student to choose the correct strategy in learning vocabulary and to help

    the students to increase their capability in mastering English vocabulary.

    $etacognitive "trategy can be used with students at all levels it is most

    experimental is a means to show the corellation cause and effect between

    two factors that intentional surface by the researher with eliminate or reduce

    another factors that disturb.

    This research concludes as !uasiBexperimental that the researcher

    needs to establish regular instruction into two groups. %amely experimental

    group and control group. +oth groups were treated by using same test 2preB

    test and postBtest4 and the researcher given treatment for both groups with

    different stategies. The experimental group is treated by using linkword or
