1 CHAPTER I INTRODUCTION A. Background of the Study

Writing, listening, speaking, and reading is an essential ability in the English language. Writing also plays a vital role in daily communication. People can communicate their ideas, feelings, and thoughts through written forms, such as messages, letters, or other social media. Like the writers share with the readers through their books or newspaper. So, writing can be said as a language skill used to communicate indirectly, whether people can't face to face each other.

Students can improve their thinking skills and English abilities, such as grammar and vocabulary, by participating in writing activities. As stated by (Raimes, 1983), some functions of writing include: interacting with a reader, expressing ideas without the pressure of face-to-face conversation, researching a subject, recording experience, and being acquainted with written English language norms. As a result, it is essential in our daily lives since it enables us to communicate and convey our thoughts to a reader. We may express ourselves through writing if we have anything, opinions, or ideas in our heads.

Writing is an essential component of any language text because of the close relationship between writing and thinking. Writing allows us to deal with our ideas and thoughts in an attempt to make them make sense. According to Penny (2009), the aim of writing is, in theory, the expression of ideas that convey a message to the reader; the ideas themselves should perhaps be regarded as the essential part of the writing. It indicates that we must pay attention to various areas of writing for the readers to grasp points of thoughts or messages.

Furthermore, writing is a difficult skill to be mastered by students. Writing is undoubtedly the most challenging skill to perfect for second language learners (C. Richards & A. Renandya, 2002). For some students in junior high school, writing is considered a complex skill. They have to arrange words to form a text, a paragraph, or an essay. Many things must be considered when delivering

(14)

2

something in writing. They have to understand the linguistic features and the generic structure of a text so that the writing they make can be arranged neatly.

Dealing with the explanation above, some texts can be written; one of them is descriptive text. Descriptive text is one of the types of English texts in writing that should be learned and mastered by students in high school. As the descriptive text is included in the English curriculum in Indonesia (Kemendikbud, 2013), knowing how the material should be composed in the ideal situation is critical for both the teacher and the students who are expected to master it in the classroom. Because descriptive texts, like other types of texts, are written not just using precise rules in the form of sentences but also by considering the purpose and meaning of each structure, a teacher must have a thorough understanding of how those sentences make sense.

Based on the writer's experience during PPKT or teaching practice at the seventh-grade of Islamic private junior high school in Tangerang, the students face difficulties comprehending or writing descriptive text. Many of the students are hard to finding and developing ideas. Students frequently struggle to grasp the text's main theme and supporting information. They also have trouble recognizing the generic structure and language features of descriptive text. Furthermore, students typically struggled with producing descriptive texts since they must utilize the present tense, which is challenging. They have a limited vocabulary in writing, mainly when writing descriptive texts.

Other researchers found similar research regarding the several problems of writing the descriptive text for students. Firstly, they struggle to grasp writing, particularly for EFL students in Indonesia, because there are structural and grammatical variations between Bahasa and English (Ariyanti, 2016). Secondly, they difficult to express their ideas on paper (Sundana, 2017). Thirdly, some paragraphs in the descriptive text were written in one phrase alone, and the paragraph's topic was still unclear (Fitri, 2017). The following is the most important. Indonesian students experience specific writing challenges, such as trouble formulating ideas, an unenthusiastic student attitude toward the instruction, and grammatical issues (Maisitoh, 2015). Furthermore, some students

(15)

3

could not finish their writing at the end of the time set because of fewer ideas and vocabulary (Yoandita, 2019).

Moreover, it is highly recommended that teachers choose and prepare various media to engage students, encourage active learning, and require them to participate well in the teaching-learning process. Gunning (2000, cited in Maisitoh, 2015) showed that establishing an engaging environment for word acquisition can substantially influence student growth. Furthermore, Burden (2011, cited in Sipayung 2019) said that word wall is adaptable to any subject and grade level and has proven to be a highly effective learning and teaching tool. So the writer tried to overcome the problems above by applying word wall media to increase the students writing ability of descriptive text.

According to Mustafa (2017), the word wall activities play an essential role in studying the meaning of words added to the word wall from diverse disciplines and literature. Word wall is usually located on a bulletin board or wall.

This media is generally used by the teacher in teaching new words to the students.

It is easy for students because some words provide the word wall. It can help the students to find the idea for their writing. Word wall encourages students to work independently by offering quick access to information to finish their reading and writing assignments (Judith, 2003).

Based on the research's background, this study aims to investigate whether there is an effect given by word wall media on students' writing ability of descriptive text. Moreover, the writer wants to measure the impact of word wall media on students' writing ability of descriptive text. This study is anticipated to have significant implications from the theoretical point of view and technically.

The research question driving this investigation is "What was the effect of using word wall media on students' writing ability of descriptive text?"

B. Identification of the Problem

Based on the background of the study, there are several problems that can be identified:

1. Most of the students have difficulty to determine their ideas.

(16)

4

2. Most of the students have difficulty to identify the generic structure of descriptive text.

3. Most of the students have difficulty to write the descriptive text because of the limited vocabularies.

4. Most of the students are not active during English learning process.

C. Limitation of the Study

Based on the identification of the problems above, the problem of this research was limited on the effect of using word wall media on students’ writing ability of descriptive text at the seventh grade students in an Islamic private junior high school.

D. Formulation of the Study

The formulation of the study is in the following question: “What was the effect of using word wall media on students’ writing ability of descriptive text?”

E. Objective of the Study

The objective of this study is to obtain empirical evidence about the effectiveness of using word wall media on students’ writing ability at seventh grade students in an Islamic private junior high school.

F. Significance of the Study

The results of this study are expected to give contributions to English teachers, students, and the further researcher.

For English teachers, this research is expected as an additional reference that may be useful for the teacher that using media can be interesting in teaching and learning process. Next, for students, this research is expected to be a useful for students to improve their writing especially in descriptive text. Moreover, for the further researcher, this study can give general knowledge about how to improve students’ writing ability of descriptive text.

CHAPTER III

RESEARCH METHODOLOGY A. Place and Time of the Study

The research took two classes of the seventh grade of Islamic private junior high school that is located on Jl. Pahlawan No. 18 Rempoa Ciputat Tangerang Selatan in academic year 2018/2019. The research conducted in five meetings for both experimental and control classes included pre-test at the first meeting, then the treatment for the experimental class started at the second until forth meeting and the post-test was held at the last meeting.

B. Research Method and Design

The method of this study was quantitative research. This method was chosen because it emphasizes numerical analysis of data gathered through test using statistics (Ary et al., 2010). It involves data collection, which is typically numerical, and as the methodology for data analysis. The quantitative method is only concerned with determining the state of the situation in the field and reporting on what occurred. Frankel and Wallen stated that basic identically experimental research is simple and unpretentious; attempts anything happens (Fraenkel & Wallen, 2009).

The design of this research was a quasi-experimental study. In a quasi- experimental study, groups that are already organized based on instructional subject are used in an experiment rather than randomly selecting subjects to experimental treatments (Ary et al., 2010). Therefore, the researcher did not have to do any random pre-selection processes because the classes were already assigned. The procedure began with the researcher giving a pre-test to both classes, the experimental and control classes.

Below is the experiment design:

* The independent variable is Word Wall while the dependent variable is descriptive text.

C. Population and Sample of the Study

In this research, the seventh grade students of an Islamic private junior school academic year 2018/2019 were the population of the research. This research was used purposive sampling as a sampling technique because the sample is taken based on certain purposes of the research (Cohen et al., 2007).

The sample for this research consisted of two classes, class 7.1 as a control class which was taught without using word wall media and class 7.2 as an experimental class which was taught by using word wall media. There were 50 students participated in this study. Based on the results of the pre-test scores, the researcher assigned the two classes into experimental and control class.

D. Research Instrument

This study used test as an instrument. The test was chosen as the instrument by the researcher because it was a suitable instrument for gathering data in this study. In this test, students were asked to write descriptive text. The aspects presented in this instrument include introduction and description. It was given twice: once as a pre-test and once as a post-test. A pre-test is a test to know and evaluate students’ knowledge before conducting the treatment. Treatment is a process of teaching writing of descriptive text by using word wall media. Post-test is given after the treatment. The purpose is to know whether the word wall media is effective towards the students’ writing of descriptive text. As for the instrument, it can be seen in the appendix.

E. Technique of Data Collection

In this study, the data was gathered using the test technique. The data was collected from the pre-test and post-test results. The procedure started by giving pre-test to both experimental and control class. Then, the experimental class was

(19)

given treatment by implementing the word wall media in learning descriptive text while controlled class was not given word wall media as a treatment.

The writing test is used to gather the data and to determine the difference of the scores from both tests. Pre-test was used to measure the students’

understanding in writing descriptive text before the treatment was given, while post-test was used to measure students’ writing of descriptive text when the treatment had been done. From the result, the writer wants to know whether the word wall media effective or not in students’ writing of descriptive text.

In counting the score of pre-test and post-test, the analytical scoring rubric was used to define some grades for the students’ writing of descriptive text. To assess the writing score of the students’ in the pre-test and post-test, it was counted by analytical scoring rubric (Weigle, 2009).

F. Technique of Data Analysis

After obtaining the students’ writing score of pre-test and post-test, the researcher measure normality and homogeneity of the data were tested by using SPSS. If the data distribution was normal and homogeneous, the analysis would apply the t-test hypothesis testing. The researcher used t-test formula to conduct t- test in manual calculation. T-test is used to compare the significant between experimental class which use word wall media in teaching writing and control class by not using word wall. The formula is shown as below (Sudijono, 1987):

(21)

to= M1 M2 SEM1 M2 to = The value of “t observation”

M1= Mean of the differences of Experiment Class M2= Mean of the differences of Control Class SEM1= Standard Error of Experimental Class SEM2= Standard Error of Control Class The process of t-test was as follows:

1. Determining mean of variable X (experimental class):

Mx = fx N1

x: Sum of the students’ score of experimental class N₁: Number of the experimental class students

2. Determining Mean of Variable Y (control class):

My = fy N : Sum of the students’ score of control class N : Number of the control class’ students

3. Determining standard of deviation score of variable X:

SDx = √ x2 N1

SDx: Standard deviation score of experimental class 4. Determining standard of deviation score of variable Y:

SDy = √ y N SDy: Standard deviation score of control class

(22)

5. Determining standard error of mean of variable X:

SE x = SDx

√N₁ 1 6. Determining standard error of mean of variable Y:

SE y = SDy

√N 1

7. Determining standard error of difference mean of variable X and Y:

SE x – SE y = √SE x SE y 8. Determining t0:

t0 = M – MY SE x – SE y 9. Determining degree freedom (df):

Df = (N₁ N ) – 2 Explanation:

M1 : The mean of gain score of experimental class.

M2 : The mean of gain score of controlled class.

: The total gain score of experimental class.

Y: The total gain score of controlled class.

: The total gain score minus of experimental class.

Y : The total gain score minus of controlled class.

SD1 : The standard deviation of gain score of experimental class.

SD2 : The standard deviation of gain score of controlled class.

SEm1 : The standard error mean of experimental class.

SEm2 : The standard error mean of controlled class.

N1 : The total number of students in experimental class.

N2 : The total number of students in controlled class.

In order to measure whether the effect size of technique was strong, the writer adopted Cohen’s theory with formulation as follows (Cohen et al., 2007) :

(23)

d= mean of group A - mean of group Pooled Standard Deviation

Pooled Standard Deviation=Standard deviation of group 1 standard deviation of group 2 2

After gaining the results, it could be interpreted based on the criteria:

0-0.20 is weak effect, 0.21-0.50 is a modest effect, 0.51-1.00 is a moderate effect, and > 1.00 is a strong effect.

G. Statistical Hypothesis

This research is designed to find out whether there is a significant effect on the writing ability at seventh-grade students at Islamic private junior high school by using word wall media in teaching writing. Hypotheses are used to find the answer to the research question and draw a conclusion for the research. The hypothesis of research can be formulated as follows:

H0 = to < tt

(There was no effect of using word wall media on students’ writing ability of descriptive text at the seventh-grade of an Islamic private junior high school).

Ha = to > tt

(There was an effect of using word wall media on students’ writing ability of descriptive text at the seventh-grade of an Islamic private junior high school).

And then, the criteria used as follows:

1. If to > tt, the alternative hypothesis (Ha) is accepted and the null hypothesis (Ho) is rejected. It means that there is significant difference of students’

writing ability of descriptive text between students who taught by word wall media and students who taught without using word wall media.

2. If to < tt, the alternative hypothesis (Ha) is rejected and the null hypothesis (Ho) is accepted. It means that there is no significant difference of students’ writing ability of descriptive text between students who taught by using word wall media and students who taught without using word wall media.

(24)

12 CHAPTER V

CONCLUSION AND SUGGESTION A. Conclusion

The study observed that using the word wall media in teaching descriptive text writing helped learners learn how to produce descriptive texts and made learning more enjoyable. Based on the initial results, it is possible to infer that the usage of word wall media for teaching seventh-grade students to write a descriptive text substantially influenced students' writing abilities. It could be shown through the statistical analysis in which it was found that the mean score of students' writing achievement in the experimental group was higher than the mean score of the students in the control group. It indicated that the students' writing achievement in the experimental group was better than the mean score of students in the control group.

This research used a quasi-experimental design to gather empirical evidence for the effectiveness of the Word Wall on students' writing ability of descriptive text at Islamic private junior high school in the academic year 2018/2019. According to the previous chapter's data, using the word wall media significantly affects students' writing ability of descriptive text.

In addition, the researcher used Cohen's formula to calculate the effect size. It was also supported by the effect size being classified as a modest effect based on the effect size calculation. In conclusion, this study found that using the word wall media on students' writing ability of descriptive text at seventh-grade had a modest effect size compared to not using it.

B. Suggestion

Based on the conclusion above, the researcher would deliver some suggestions to English teachers, students, and the further researcher.

English Teachers are supposed to give learning strategies for teaching writing in an enjoyable, comfortable, and easy-to-understand way. They can utilize Word Wall media in writing class, and students who employ Word Wall

(25)

13

are more enthusiastic about writing English. Before using Word Wall as a medium, English teachers should ensure that their students understand and have all of the relevant knowledge. Moreover, students need to be more active and optimistic when learning English. They are encouraged to be involved in English class and take an active role in growing their vocabulary. Furthermore, the researcher may find additional relevant research on writing in the future, especially in observing the students' writing ability of descriptive text.
