ABSTRACT
Marpaung, Misida Nova Sari Dewi. 2014. 2103321023. The Effect of Applying
Clustering Technique on Students’ Achievement in Writing Analytical
Exposition Text.A Thesis.English Department.Faculty of Languages and
Arts.State University of Medan.
This study aims at investigaing the effect of applying clustering technique on
students’ achievement in writing analytical exposition text. It was conducted by
using experimental research design. The Population of this research was the
eleventh (XI) grade students of SMAN 2Pematangsiantar. The number of the

samples taken was two classes.The first class (XI PMIA 1) which consists of 30
students as the experimental group, while the second class (XI PMIA 2) which
consists of 30 students as the control group. The experimental group was taught
by using clustering technique. The instrument for collecting the data was writing
test. To obtain the reliability of the test, the writer used the Pearsons’ Product
Moment Formula, The resut of the study showed that the reliability of the test was
0,90. The data were analyzed by using t-test formula, the analysis showed that the
score of students in the experimental group was higher than the score of students
in the control group at the level of significance 0, 05 with the degree of freedom
(df) 58; the t-observed is 4, 61 while the t-table is 2, 00. Therefore, the null
hypothesis (Ho) is rejected and the hypothesis alternative (Ha) is accepted.
Keywords: Clustering Technique, Writing Analytical Exposition

CHAPTER I
INTRODUCTION

A. The Background of the Study
English is one of the formal subjects that is included in the curriculum. It
has been taught from the primary up to university level.The Department of
National Education has made English as a compulsory subject and positioned it as
the first foreign language to be taught in school based on the curriculum. In order
to be able to communicate in English, students are expected to master the four
english skills, they are the mastery of the receptive skills (reading and listening)
and the mastery of the productive skills (speaking and writing). One of the
language skills that will be focused in this study is the writing skill.
Writing is a process of discovery and organizingthe ideas, developing the

ideas, conveying them into paper, reshaping and revising them (Coffin et al,
2003:34). It means the students should be able to express their idea that they
discovered into paper in a text form that will be clear to a reader.Furthermore,
writing is a skill to express the ideas in an effective and organized way. Writing is
a skill that can be acquired through practice. It is also state by Grenville (2001:vi)
thatno one’s born knowing how to write – but it is a skill that most people can
learn, and the more you do it, the easier it becomes. Actually, most of the students
find some difficulties in learning writing. They think that writing text is a difficult
task to do. This assumption is wrong because writing is an activity that has a lot of
fun and makes the students more creative.

Based on the researcher’s experiences during the time spent in the Field
Practice Experience (Praktek Pengalaman Lapangan : PPL) at the State Senior
High School (Sekolah Menengah Atas: SMAN) 2 Pematang Siantar, many
students had difficulties in writing. They did not give much attention and
enthusiasm on writing task because they do not have an appropriate direct means

in getting in touch with the ideas. The researcher found the data of the XI grade
students’ writing test in the first semester at 2013/2014 academic year from the
English teacher. The teacher said that many students get the score below Minimal
Completeness Criteria (Kriteria Ketuntasan Minimal) of English lesson for Senior
High School. The score of writing test from the students can be seen in table 1.1.
