ABSTRACT
Yusuf, Muhammad. 2101121031. The Effect of Applying Clustering Technique
on the Students’ Achievement in Writing Descriptive Paragraph. A Thesis.
English and Literature Department. Faculty of Languages and Arts. State
University of Medan. 2014
This study attempts to investigate the effect of applying clustering technique on the
students’ achievement in writing descriptive paragraph. The research design of this

study was an experimental one. The population of this study was grade VII of MTSs
Al Abraar totaling to 60 students of two parallel classes. The data were obtained from
random sampling technique through lottery. The class VII-A became the
experimental group and was given the treatment by using clustering technique while
class VII-B became control group and was given treatment without using clustering
technique. The instrument of collecting data was writing test and inter-rater was used
to obtain the reliability of the test. The data were analyzed by using t-test formula. It
was also obtained that tobserved is higher than ttable (1.760 > 1.673) at the level of
significance (α = 0.05) and degree of freedom (df) = 58. It means that null hypothesis
was successfully rejected and alternative hypothesis was accepted. As the conclusion,
there is a significant effect of applying clustering technique on the students’
achievement in writing descriptive paragraph.

CHAPTER I
INTRODUCTION

A. The Background of the Study
Learning English has four integrated skills namely listening, speaking,
reading, and writing. They must be taught and applied in teaching-learning
process. They are also divided into two groups; receptive skills and productive
skills. Receptive skills consist of listening and reading. Meanwhile, Productive
skills consist of speaking and writing.
Writing as one of the four skills that should be mastered by students has
always formed part of the syllabus in the teaching of English (Harmer, 2004:31).
Writing is taught after listening, speaking, and reading. Moreover, the real fact
faced by student is writing is the hardest skill to be mastered. Oshima and Hogue
(1999:3) claim that writing specifically academic writing is not easy. It takes
study and practice to develop this skill. For both native speakers and new learners
of English, it is important to note that writing is a process, not a “product”. It
means that writing is not only a process of linking words into sentences or
paragraphs, but also it is a sequence or steps of ideas, organized thoughts and
feeling in the form of words and combined into sentence into form of paragraphs
in which every sentence is closely related one another. And writing integrates
many aspects of language such as: vocabulary mastery, words-arrangement,
grammar proficiency, and constructing paragraph.

The capability of writing as the most super power tool in communication should
be owned by students. Everyone can convey their feelings, ideas, and thoughts to
others. Tabatabaei and Assefi (2012:138) claim that writing has received a great
degree of attention not only because it plays a significant role in transforming
knowledge and learning but also in fostering creativity. Writing also needs more
knowledge. Due to the writing is the process of transforming ideas, and thoughts,
learning is important to improve writing. In addition, writing is chosen to be more
effective and efficient to convey information such as in posting letters, business
card, leaflet, poster, and much information for marketing a company’s product.
In the Curriculum of Educational Stratified Level or Kurikulum Satuan
Tingkat Pendidikan (KTSP) and written in the standard competence in the
syllabus of the first year students of junior high school, students are expected to
be able to write some genres in writing namely descriptive, and procedure. The
curriculum highlights that students have to be able to write various types of the
text genres.
One of the genres that should be mastered by students in the process of
learning English is descriptive paragraph or text. Saragih (2010:20) claims that
descriptive is used to describe a particular person, thing, or place. Kalandadze
(2007:8) states that a paragraph is a group of sentences that support and develop a
single idea or one aspect of a large and more complex topic. So, descriptive
paragraph is a paragraph that contains descriptions of a particular topic such as
person, thing, or place.

3

Based on the preliminary observation conducted in junior high school
namely Madrasah Tsanawiyah Al Abraar Tandem Hilir Grade VII, it is commonly
found that students’ performance poorly in writing.more than 71.9% students had
problems in writing. Their mean of score are still under the Minimum Criteria
Mastery or Kriteria Ketuntasan Minimal (KKM) applied by the school. The KKM
applied is 75. The mean of students’ score from class VII-A are 54.3 and 56.5 for
1st and 2nd session in 2012/2013 while another class VII-B are 53.6 and 55.8.
From the interview with the teacher, there are some problems are faced by
teacher and students in writing descriptive paragraph. First problem, students
don’t have motivation to write. The second problem is teaching method applied
by the teacher. The teacher still uses lecturing method in teaching writing.
Students are asked to pay attention to the example of one paragraph or text. Next,
they are asked to write independently.
From the conditions illustrated in advance, students’ ability in writing
descriptive paragraph tends to be very less because of the learning method applied
by teacher of English language is unsuitable anymore in the recent time. The
implication of the method applied is students felt bored and lost their interest and
they avoided continuing learning process as they had to do. The students’ also felt
that writing is a difficult activity because they need to express, transfer, and
associate their ideas into written form.
The revolution of teaching-learning process runs very fast at this present
time. Teacher is not the center of the learning process anymore and sometime it is
called as “Teacher Centered Learning or TCL”. The approach has been changed

4

into the needs of the students rather than those of others which are involved in the
educational process and system. This approach is theoretically said as “Student
Centered Learning (SCL)”. The teacher is functioned as a facilitator and no longer
positioned as the main source of knowledge and information in the teachinglearning process. And the main core of the teaching-learning process is moved to
the students’ activeness. If the students have difficulty in learning, that is the time
for the teacher to play the role as the facilitator to guide the students and to tell
them what they don’t know and what they don’t understand.
A paragraph is a distinct unit of thought which may contain a topic
sentence (Chitravelu, et.al., 2005:165).

Another source, Muschla (2011:113)

states that the paragraph contains a topic sentence that states the main idea of the
paragraph and other sentences support the main idea with details and examples.
As the conclusion, paragraph is a group of sentences that contains a single main
idea and supported by details and examples which is related each other. Writing a
descriptive paragraph is not easy. It needs the way to associate the thoughts and
ideas.
Coffin, et al. (2005:37) says that Clustering is a helpful technique to see a
visual representation of ideas. Kalandadze (2007:6) states that clustering is a
technique used to see a visual map of our ideas and able to make us think more
creatively in making new association. This technique will lead the students to
create and think more creatively in writing. This method is also one of the
applications of students centered learning because the students will be led to be
more active rather than the teacher in writing.

5

In addition, previous researcher, Hariani (2013) states clustering technique
helps students to improve their achievement in writing recount texts in SMPN 05
Kota Jambi. By considering the different sample, technique, and the genre, the
researcher wants to know the effect of using clustering technique in teaching
descriptive paragraph in MTsS Al Abraar. Recount genre has communicative
purpose to retell events for the purpose of informing or entertaining to the readers
while descriptive genre has communicative purpose to describe a particular
person, place or thing. Moreover, recount has generic structure namely;
orientation-record of event-reorientation while descriptive has generic structure
namely; identification and description.

B. The Problem of the Study
In accordance with the background of the study, the problem of the study
is formulated as follows;
“Is there any significant effect on students’ achievement in writing
descriptive paragraph by applying clustering technique?”

C. The Objective of the Study
In line with the problem, the objective is to investigate if there is a
significant effect of applying clustering technique on the students’ achievement in
writing descriptive paragraph.

D. The Scope of the Study
As written in syllabus of Junior High School, there are some types of
paragraph that should be mastered by students. This study is focused on the

6

students’ achievement in writing descriptive paragraph specifically on describing
personality by applying one technique that is, clustering technique.

E. The Significance of the Study
The findings of this study are expected to be relevant and useful
theoretically and practically. Theoretically, the findings of this study are expected
to be useful for the readers to broaden and to enrich their horizon in theory of
learning English and can be reference for further studies.
Practically, the findings of this study are expected to be useful for:
1) English teachers, as an alternative teaching resource to give more
information about another technique which can be applied in teaching
writing in order to enhance their competence in teaching
2) English learners, to motivate and to enable them to improve their
writing achievement
3) Decision maker, as one of source of information in making a decision in
education

CHAPTER V
CONCLUSIONS AND SUGGESTIONS

A. Conclusions
After analyzing the data, the conclusions are drawn as the following.
(1) Because of the tobserved is higher than ttable (1.760 > 1.673), null hypothesis is
rejected and alternative hypothesis is accepted
(2) The reliability of the test administered to student is 0.63 and it is categorized
as “high”
(3) And it is proven that there is a significant effect of applying clustering
technique on the students’ achievement in writing descriptive paragraph
because the students’ score results is higher after the treatment.

B. Suggestions
In relation to the conclusions, suggestions are staged as the following:
(1) The English teacher is suggested to choose and apply clustering technique
to improve students’ achievement in writing so that the students can be
helped in expressing their ideas and thoughts
(2) The English learners are suggested to be more active, creative, and enjoy in
exploring their ability in writing by applying clustering technique in order to
ease them to associate, connect, and express their thought in writing.

42

43

(3) The readers are suggested to read the findings to widen and broaden their
horizon in the theory of learning English and the decision makers are
suggested to read the findings of this study as one of the considerations in
making the decision for the policy of the teaching-learning process.
