This study was conducted to investigate the effect of the strategy of collaborative writing using scrambled-pictures on narrative writing ability of the Eighth graders of SMPN 4 Balikpapan in the academic year of 2012/2013. 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. The study was conducted for 5 meetings and involved a pre test and a post test. The result of the study suggested that English teachers need to vary the ways and support the students with the appropriate strategies in teaching and learning writing to support the students' ability in producing their good and original writing compositions. ukryj opis
