Since word cluster is one of the brainstorming techniques, it is called as the natural way in developing the writing. Word cluster is the surface of technique in
teaching writing that is consisted of word or phrase so word cluster also have the disadvantages that have been mentioned above.
2.9 Theoretical Assumptions
In teaching writing, there are many techniques that can be used by the teachers to
reach the goal of teaching learning process. As has already been stated that writing is counted as the most difficult skill, students need to consider the five
aspects of writing namely content, grammar, organization, vocabulary, and mechanic. Besides some cases showed that it is hard to students are facilitated to
plan their ideas in systematical way. Word cluster is a technique that can be used to teach descriptive text writing. It is
also a tool that helps the students to express their ideas in writing descriptive text. In the teaching process, the teacher guided the students to organize and write
descriptive text including the five aspects of writing; content, grammar, organization, vocabulary, and mechanic.
The researcher assumed that word cluster enables the students to write descriptive
text writing more easily because it helps them to develop the ideas that they will put in their descriptive text writing. In other words, it will help the students to
make the content of their writing relate with the topic that have given.
2.10 Hypothesis Based on the theoretical assumption above, the writer formulated the hypothesis:
“There is improvement of students’ descriptive text writing ability after being taught through word cluster.
”
III. RESEARCH METHODS
In research methods, research design, population and sample, data collecting
technique, instrument of the research, research procedure, data analysis, and table of specification in writing test are presented. It is presented to clarify research
question “is there any improvement of students’ descriptive text writing ability after being taught through word cluster
?”.
3.1 Research Design
This research was a quantitative research. It applied an experimental method. It
aimed to find out whe ther there is any improvement of students’ descriptive text
writing ability taught by using word cluster. This research would involve one group of students with pre-test and post-test design.
The design of this research could be represented as follows:
T1 X T2
Hence, it could be said that the illustration above classifies that it was a true experimental design. The experimental class was selected purposively. To add,
pretest would be given to see the initial ability of the experimental class.
