c. Interaction between teaching methods used, Collaborative Writing method and
Direct Instruction method A, and students‟ Creativity B in teaching writing. It means that in teaching writing, the students who have high creativity are
more appropriate taught by using Collaborative Writing method than those are having low creativity. On the contrary, the students who have low creativity are
more appropriate taught by Direct Instruction method than those are having high creativity.

CHAPTER IV THE RESULTS OF THE RESEARCH
This chapter presents the result of the research which is administered to investigate the effectiveness of Collaborative Writing method in teaching writing
skill viewed from students‟ creativity. The discussion includes the implementation of the research, research design, prerequisite test, hypothesis test, discussion of the
result.
A. The Implementation of the Research
In the treatment, two teaching writing methods were implemented. The Collaborative Writing method was implemented on the experimental group, and
the Direct Instruction method was implemented on the control group. At first, the researcher conducted the treatment in ten meetings. Finally, after having
treatment, both groups were post-tested. The lesson plan used for both experimental group and control group were
designed by the researcher. Both groups had the same materials, referring to the catalog used in STAIN Jurai Siwo. In Development the material, the researcher
used some topics in descriptive text attached in the lesson plan, such as: My weekend, My Idol, My favorite food, My favorite place, My Ideal Bedroom, What
Happens to Your Body When You are Nervous, The Shoes that You are Wearing Today, A Pet that You Would Like to Have, Describe Your Family Portrait that
