THE EFFECT OF USING COOPERATIVE SCRIPT ON STUDENT’S READING COMPREHENSION AT GRADE ELEVENT OF SMA NEGRI 2 PEMATANGSIANTAR

This study is about the effect of Cooperative Script on students’ reading comprehension. Problem raised in this research was: What is the effect of using Cooperative Script on student’s reading comprehension at Grade eleven of SMA Negeri 2 Pematangsiantar? To answer the question, experimental design was conducted to this research. The population of the study was the 2019/202 academic year firstsemester grade XI students of SMA Negeri 2 Pematangsiantar. The samples were two classes, namely XIPMIA3 and XIPIS 1, with the total was 68 students selected by applying random sampling. The sample was divided into two groups. Experimental group (XI PIS 1) was taught by applying Cooperative Script Method while the control group (XI PMIA 3) was taught by applying explaining method. There were two data used in this research. They were pre-test and post-test. The data were analyzed by using t-test formula to show the effect of applying Cooperative Script Method on students’ reading comprehension. After analyzing the data, the finding indicates that t-observed was higher than t-table (6.263 > 1.668)) with the degree of freedom (df) = 66. It means that applying Cooperative Script Methodhas significantly affected students’ reading comprehension.

English has four basic language skills, they are listening, speaking, writing, and reading. Sandiku (2005:29) defined the four skills as: Listening and Speaking: these two skills are highly interrelated and work simultaneously in a real life situation. So, the integration of the two aims at fostering effective oral communication. Reading and Writing: they form a strong relationship with each other as a skill. They are tools for achieving effective written communication. The researcher can conclude that the four basics of English cannot be separated because they are related to another. Four of them have to be mastered by someone who learns English. Reading is one of the four skills in English that has an important contribution to the success of learning this language. According to Sandiku (2005:30) stated that "Through reading, we learn a lot and it is the most prominent language skill. "Reading is related with daily life because people read many kinds of written materials such as newspaper, magazines, academic book, and so on. Reading can help people to get any information, knowledge, and even problem solution. So reading is very important to the learner.
In this era, students are always using the internet to get information and on the internet often contain the English language in an advertisement or in the information. Furthermore, in this era, all the students only know to read but difficult to comprehend. Moreover reading needs more comprehension, because "Reading" is different with "Reading Comprehension". Reading use eye but Reading Comprehension needs heart. So, reading comprehension can be defined as reading by the eyes of the heart. Reading related to comprehension or understanding. The people get information for reading when they can understand the context of reading. It means that comprehension or understanding something is the main goal of reading. The reading comprehension is very important to a student so the English teacher should make the reading learning process joyful and interest to a student. The English teacher can make the joyful and interest learning process use the strategy that appropriates to student or class atmosphere, use the interest media to make the student more attention and interest with the learning process.
In fact, many students do not master the reading comprehension because of many problems. The problems can appear from students and teacher. The problems that appears from students are less vocabulary, not interest with reading learning process or materials reading. The problem that appear from the teacher like not use media, strategy, technique and material reading that not appropriate to student or class atmosphere.
Based on the researcher's experience in her teaching practice of eleven grade at SMA Negeri 2 Pematangsiantar. The researchers found that the students' reading comprehension was still low. By checking the mean score of the students' reading comprehension was 60. According the data that researcher found while teaching practice in SMA Negeri 2 Pematangsiantar. This score was categories as poor level based on The Dirjen Pendidikan Dasar dan Menengah classification (2005:25), the minimum completeness criteria for students is 75. It was found when the students studied reading in the class. Most of them did not competent to comprehend English text well. Many students could read the word in passage perfectly but were unable to answer the questions. They could say the words, but they were unable to gain the meaning from words. They found hard to comprehend reading materials. The researcher also found that the teacher only asked the students to read, and then they had answered the question without giving explanation about the text first. Therefore the students did not understand what they read. As a result, they could not answer the whole questions correctly. In this case, the students have to read critically, and the teacher must select the suitable technique or strategy to teach it.
To solve the problems above, there are some methods in teaching to make learning process in the classroom become more interesting and even fun. One of them is Cooperative Learning. According to Bolukbas, Keskin, and Polat (2011:331), "Cooperative learning is a learning method in which learners help each other in terms of their learning process by making up small homogenous group to achieve a common goal, and in which group performance is rewarded in several different ways". According to Majid (2014), there are any purpose of implementing cooperative learning It increases students' performance in accomplishing academic assignments. Besides that, it helps the students to understand complex concepts. One method of cooperative learning which is suitable in teaching reading comprehension is cooperative script. According to Slavin (1996:29) as cited by Riska, Marahaeni and Suputra (2018) states "Cooperative scripts is a term for the practice of two students working together to summarize material and support one another's understanding and recall of the important facts and concepts contained in the material read". Based on the explanation above, the researchers raised a question for: What is the effect of using cooperative script on Students' reading comprehension at Grade eleven of SMA Negeri 2 Pematangsiantar."

A.Research Design
This research uses experimental quantitative design. According to Creswell (2011:4) a quantitative research is a mean for testing objective theories by examining the relationship among variables. This research method is used to describe variables, to examine relationships among variables and to determine cause-and-effect interactions between variables (Burns & be measured, typically on instruments so that numbered data can be analyzed using statistical procedures. A quantitative research strives for testable and confirmable theories assumption. It seeks scientific explanation that includes the discovery of laws governing not only the behavior.
The final written report has a set structure consisting of introduction, literature and theory, method, result and discussion.
Furthermore, the data are taken by using the experimental design. According to Cohen& Elizabeth (2007:270) experiment research is to test the impact of a treatment or intervention on an outcome, controlling for all other factors that might influence that outcome. In conducting the experimental research, the sample will be divided into two groups, namely experimental group and control group. It is figured as following:

Population
According to Sihombing (2019:37) stated that sample is the small proportion that is taken from population or analytical needing. Based on the statement it is implied that not all population is necessary involve in the study but only in the certain number of students are selected as representative. Before the sample is collected, the researcher has to determine the population.
According to Ary, Jacobs, and Sorensen (2010:167), Population is defined as all members of any well-defined class of people, events or objects.
The population of this research is grade eleventh students of SMA N 2 Pematangsiantar.
There are eleven parallel classes, seven of them are Science program, and the others are Social program. Each class consists of 30 up to 40 students, total are 385 students. Below is the table of the population of the grade eleven students of SMAN 2 Pematangsiantar. The researcher chooses the second grade students because they are learning some kinds of text in this year and one of them was Report text.

Sample
Creswell (2011:142) defined sample is a subgroup of the target population that the researcher plans to study for the purpose of making generalization about the target population.
The sample of this research is two classes which are XI-IA3 a control class because they are active with better achievement than other class and XI-IA4 as an experimental class because they have lower achievement. It can be proved based on the previous explanation in background that average of score that the students get when the teacher gives the test is 60. Even though the minimum completeness criteria (KKM) determined by the school in English subject is 70.
This class is suitable to applied Cooperative Script to improve their achievement.

1.Test
The instrument of this research is a test. According to Ary, Jacobs and Sorensen (2010:201), a test is a set of stimuli presented to an individual in order to elicit responses on the basis of which a numerical score can be assigned. The test used is fill in the blank test intended to measure writing ability of students. There are two kind of test used to collect the data; pre-test pre-test and post-test. There will be 20 questions.

Scoring the Test
The researcher conduct the test consist of 20 questions, with the score as follows: Students' score = X 100 (Arikunto, 2009:236)

Media
There are some media that researcher using in this research; a) Handphone, the researchers use handphone in this research to takes a picture during the treatment as the research documents.

b)
Video Player by YouTube, the researcher using video to help the students understand about the text more clearly, the video that will be play related with the topic of the text.
c) The other documents as the instrument of the research are the lesson plans, class materials, the paper test and examination paper that collect during the research.

D. Technique of Data Collection
There were some steps in collecting the data for this research. For data collection technique researcher used test. Test is used to measure the competence of a person and also to achieve the objective. The data was collected by giving vocabulary test. The test was conducted twice.

Pre-Test
Pre-test was given to both experiment and control group. This text was conducted to find out whether the two groups are relatively equal in reading comprehension.

Treatment
After the pre-test was conducted, treatment was given to experimental group. They were taught by using Cooperative Script Method while the control group was taught by using explaining method. Both groups were taught the same material. The teaching procedure can be seen as the following:

Post-Test
After the treatment, the same test was given to each group. This post-test was conducted to see the result whether the method is effective or not.

E. Technique of Data Analysis
After the researcher collect the data and then the researcher analyzes the data by The result of T-test is = .
. Testing hypothesis showed that t-test (17.04) is higher than t-  In chart 2 above, Testing hypothesis showed that t-test (17.04) is higher than t-table (1,68) at level of significance 5% for two tailed test. The result get by using manual calculation. (2018)  After conducting the research in SMA Negri 2 Pematangsiantar the researcher found the differences in students' reading coomprehension between both of class which one that applied

Cooperative Script Method and without using Cooperative Script Method. The finding of the research after analyzing the data the researcher finds the answer of the problem to find out what is the effect of using Cooperative Script method in teaching report text to improve students' reading comprehension and as the result the class that applied Cooperative Script Method have better achievement on their test especially in comprehend the text that used in reading comprehension.

CONCLUSION
After analyzing the data presented in the previous chapter, it is found out that using Cooperative Script significantly affects the students' reading comprehension at grade eleven SMA N 2 Pematangsiantar. It can be seen from the result showed that the value of t-test is higher than value of t-table. (6.263 > 1.668)) with the degree of freedom (df) = 66. Based on the data analysis of the study, the result indicates that the alternative hypothesis (Ha) was accepted. It means that there is the significant effect of using Cooperative Script significantly affects the students' reading comprehension at grade eleven SMA N 2 Pematangsiantar. Related to the conclusion, the researchers would like to give a recommendation for English teachers to consider Cooperative Script as a method in teaching reading to their students because it will be possible to make students interesting with the text and to comprehend the information within the text. The use of Cooperative Script is useful to increase students' comprehension in teaching reading. The
