    3/29

    In experimental class, the students had given the treatment for 4 meatings

    about speaking by using pair work before they practice conversation to prove the

    hypothesis accepted or not.

    a. The First Meeting

    The cycle was conducted on October 12th, 2011. To open the activities of

    the teaching and learning process, the researcher spent ten minutes to lead

    students to English speaking by asking who was absent on that day. Moreover, the

    researcher asked to practice speaking in front of the class to know how are their

    ability in speaking

    In the meeting, it was found that the students have many difficulties in

    learning speaking and use it in their communication. After that, he began to teach

    speaking by using pair work. He taughth about introducing by asked them to be

    in pair. By pair work, the students become interested and want to speak about the

    topic because they did not feel shy. Uncounsiously, they practice and use

    vocabulary together at the same time and become more interactive.

    After the teaching learning process had done, the researcher concluded the

    point of study and tell them that the study would be held again on october 14th,

    2011. Then, the researcher gave his gratitude for the corporation during the

    research conducted.

    b. The Second Meeting

    4/29

    In this meeting, the teacher began the class with greeting and checking the

    students attendance. Then, brainstorming the students knowledge about the

    topic, there is introducing. But here, the study did widely about introduce your

    friend. The researcher introduced the speaking skill by asked them to be in pair.

    Then teacher gave the students a passage of speaking that was the researcher

    wants to tell to them. The teacher began to tell the dialogue with his own word

    based on the text given. And the students listened the teacher spoken. In the

    second step, the teacher explained and spoke in front of the class how to produced

    word into short dialogue. In the third step, the teacher gave a passage of dialogue

    to students and they worked in pair with their friends and practiced the

    conversation into their own word based on the explanation that teacher has given.

    While the students practicing the task, the teacher controlled and helped them,

    also gave them motivation. After they finished with the task, the students needed

    to practice the task for several times, and asking their teacher whatever they had

    problems on speaking.

    Next, after the teacher felt that the students have no more problems during

    practicing, the researcher and students agreed to present the pair work in front of

    the class, the researcher gave a chance for students to perform their action in turn.

    The students were given ten minutes for presentation. However, the researcher

    gave the model first.

    The students were actively involved in speaking although they made noise.

    After the first pairs were ready to perform the action in front of the class. The

    other students paid attention as well. They were waiting for their turn. The

    24

  • 7/30/2019 Chapter III Nuraina

    5/29

    researcher asked the other students to keep on paying attention toward their

    friends performance. It would become their additional input. Due to five minutes

    left and it is impossible to finish the students presentation all. So, the teacher

    stopped. The rest of them would be presented at the third meeting. Finally, the

    researcher asked them to practice at home and after the bell rang; the teacher

    ended the class by saying good-bye and good-luck.

    c. The Third Meeting

    In third meeting (October 19th, 2011), the researcher prepared the class for

    the English subject, checking the students attendance, and asking them whether

    they practiced the dialogue at home. After that the researcher asked the rest of

    students to present their turn as the previous conversation. After the students

    finishing their action, the researcher began the study with new topic. It is about

    hobbies. The researcher divided the students into pair work again. The

    researcher asked each pair work to arrange conversations that entitled hobbies.

    During the pair working the task, the teacher rounded the class and helped them

    while they had problems with grammar, fluency, comprehension and

    pronunciation. They finished the task and the researcher gave them ten minutes to

    practice it.

    Next, without wasting any time, the teacher asked them to present their

    dialogue in front of class. Some students seem satisfied with their work because

    they are happy to perform the dialogue. However, many of them still speak very

    slowly when presentation by using pair work in front of class so that the teacher

    has to come closer to listen what they were talking about.

    25

    D. Data Analysis

    The data of this thesis ware collected through experimental teaching. It

    was conducted to the first year students of SMA Negeri 1 Baktiya, Kab. Aceh

    Utara. The research was held on September 6 th, 2011. In the activities of the

    research the writer tried to find the data about the students capability of the first

    year students in learning speaking. In addition, the researcher wanted to know the

    difficulties faced by the students in learning speaking.

    The data about the students capability in learning speaking ware collected

    through post-test. The data about the difficulties faced by the students ware

    collected by giving questionnaires. Futhermore, the writer also did the interview

    with Headmaster and English teachers to collect additional data about the school

    and teaching learning process.

    The writer was going to analyze the the data which were colleted by

    giving test. In line with this, the writer would like to use the statistical procedures,

    32

  • 7/30/2019 Chapter III Nuraina

    13/29

    such as range, interval, mean, standart deviation, and t-score. To avoid

    misunderstanding of terms, the writer would like to explain them briefly as in the

    followings:

    1. Range is the difference of the highest score with the lowest score.

    The formula is:

    R = Hs-Ls

    Where:

    R = Range score

    Hs = Highest score

    Ls = Lowest score

    2. Interval is amount of class.

    The formula is:

    I = I + 3,3 log N

    Where:

    I +3,3 log N = Available score

    Logn = Logarithm

    N = Number of students

    3. Class interval is the number of score that has been grouped based

    on the expected interval.

    The formula is:

    33

  • 7/30/2019 Chapter III Nuraina

    14/29

    P =I

    R

    Where:

    P = Length of the interval

    R = Range of the score

    I = The amount of interval class2

    1. Analyzing the Pre-Test of Experimental Class

    Furthermore, the writer analyzes the data by using the formula above. To

    make it easy to analyze. The writerfirstly arranges the data from the highest score

    to the lowest score.

    56 61 67 67 78

    After arranging the test score, the writer then analyzes the available data

    by following the procedures:

    1) For the first step, the writer measure the ranger score, where the highest

    score was 78 and the lowest score was 17. And the results was:

  • 7/30/2019 Chapter III Nuraina

    15/29

    R = Hs Ls

    = 78-17

    = 61

    2) The second step was to find out amount of interval. The results was:

    I = 1 + 3,3 Log N

    = 1 + 3,3 Log 30

    = 1 + 3,3 (1,477)

    = 1 + 4,8741

    = 5,8741

    = 6

    3) The next step was to find out the class interval score. The results was:

    P =I

    R

    = 6

    61

    = 10,16

    = 10

    After getting score of range, interval and class interval, the writer nade the

    frequency distribution of the post-test score in order to out the mean. So, it could

    be seen in the following table

    E. The Analysis of Interview

    The interview for the teacher have done to analyze whether the teacher

    have some problems or difficulty in teaching speaking. Learning speaking is a

    very important part of learning a language. Here some reasons why speaking is so

    difficult to study

    1. Verb Tenses

    English has a relatively large number of verb tenses, the correct mastering of

    which is important for communicating shades of meaning in English. To

    complicate the difficulty, English uses many auxiliary words, instead of verbal

    inflection, to create its tenses.

    2. Writing System

    28/29

    There is often little connection between the way a word is written and the way

    it is pronounced. Consider cough vs. through and flood vs. door. Other

    inconsistencies include heteronyms, words that are spelled the same but

    pronounced differently, such as wound (wrapped up) and wound (an injury),

    and row (a fight) and row (a line of something).

    3. Plural nouns

    Though most nouns in English simply add "s" to their singular form to create

    the plural, there are many exceptions to this rule. These include words ending

    in "f" or "fe" (wife/wives, knife/knives), words ending in "y" (spy/spies,

    fly/flies), words that change interior vowel sounds (man/men; mouse/mice),

    and Old English plurals, such as child/children and ox/oxen.

    To answer these problems, the teacher gives some ways or strategies in

    learning vocabulary. There are:

    - The students asked to learn the words that are important to the

    subjects of study

    - The students asked to learn the words that read or hear again and

    again

    - The students asked to speak aloud as often as possible and be sure

    to let them know it is fine if they feel the need to repeat things over and over,

    as well.

    - The teacher uses picture and create a learning game for the

    students. Many pictures of common items such as fruits, animals and places

    are prepared in teaching speaking.

    F. Examining Hypothesis

    Based on the result above, the writer examined his hypothesis. There was

    only one hypothesis, there is Using pair work can improve speaking skill of the

    first year students of SMA Negeri 1 Baktiya..

    The researcher could understand that it is easy for the students to study

    speaking by using pair work and they could improve their speaking easily. The

    students was interested in following the lesson until the end of experimental

    teaching. So, it could be said that pair work was very effective in improving the

    students English vocabulary.

    It can proved by looking the comparison before and after the treatment

    done on t-score. At pre-test, the students get t-score -2,34; while at post-test, the

    students get t-score 6,74. it means t-score of post-test (6,74) > pre-test (-2,34).

    Based on the explanation above, it can be concluded that the writers

    hypothesis can be proved or it can be accepted, or it can be said the hypothesis is

    well-accepted.
