Also explored the perceptions of the eighth graders of SMPN 4 Balikpapan toward the strategy of collaborative writing and the using of scrambled-pictures as aids in their narrative writing. The study involved two intake classes which consisted of 37 students each. One class was considered as experimental group and the second one was as control group. In the control group, the students did the writing activity using scrambled-pictures as aid but without collaborative writing. In the experimental group, the students were supported by the strategy of collaborative writing using scrambled pictures.
