THE EFFECT OF USING THE CLUSTERING TECHNIQUE ON THE EIGHTH YEAR STUDENTS’ WRITING ACHIEVEMENT AT SMPN 2 CLURING BANYUWANGI IN THE 2011/2012 ACADEMIC YEAR
Abstract
Indonesian students, as EFL learners, often experience problems in  English 
writing especially the difficulties  to generate  the ideas. They have to do the 
prewriting activity before doing the writing process to make it easier to be done. To 
help the students’ problem in generating the ideas, the teacher needs to give a 
prewriting technique. 
Based on the above reason, the researcher used  the  clustering technique in 
teaching writing to the students.  It  is one of the prewriting techniques that can help 
the students to find the ideas by drawing some words by using balloons and 
connecting each word by using lines. By using the clustering technique, the students 
can know the relation of each word,  so they can generate the ideas easily.  The 
clustering technique can help the students to solve their problems  in generating the 
ideas. By using it, the students can find some words related to their writing, so they 
can prepare the vocabularies before doing the writing process. The students are asked 
to do the prewriting first. They had to find the words related to the topics  by using 
clustering technique.  
This research was conducted to investigate whether or not there was a 
significant effect of using clustering technique on the writing achievement of the 
eighth year students at SMPN 2 Cluring Banyuwangi. The respondents of this 
research were the eighth year students of SMPN 2 Cluring Banyuwangi in the 
2011/2012 academic year. The researcher determined the two classes by using lottery. 
The total number of the respondent was 78 students, divided into  the  experimental 
group and the control group. The experimental group consisted of 39 students and the control group consisted of 39 students. After determining the experimental and 
control class, then the researcher gave the same pretest to both classes. After that, the 
experimental class was taught writing by using clustering technique as the prewriting 
technique, while the control class was taught writing without the clustering technique. 
After the students were taught for 3 meetings, they were given the same posttest  of 
writing. 
The primary data of this research were collected from the post test of writing 
test.  The main data of this research were  analyzed by using ANCOVA (Analysis of 
Covariance). The result of this research showed that there was a significant effect of 
using the clustering technique on the eighth year  students’  writing achievement. It 
was proven by the value of significant column of ANCOVA by  using SPSS, the 
result was 0.003. It was lower than 0.05. Based on the explanation above, it could be 
concluded that there was a significant effect of using the clustering technique on the 
eight year students’ writing achievement at SMPN 2 Cluring Banyuwangi. Based on 
the result of this research, it is recommended to the English teacher to  use  the 
clustering technique in teaching writing because it can help the students to generate 
the ideas for developing them into a recount paragraph.
