The effect of using collaborative writing technique on the 8th grade students' writing achievement

This research concerns the effect on using Collaborative Writing Technique and Individual Writing Technique to the 8th graders’ writing achievement. This research was implemented in a private junior high school in Surabaya. The researcher used quasi-experimental research using non-randomized pre-test and post-test as the design. With the level of significance at 5%, the researcher found that the t-observation (to) of the experimental group and the control group was 3.08. Since to (3.08) was greater than ttable (2.01), so Ho is rejected and Ha is accepted. It means that there is a significant difference between the writing achievement of students taught using Collaborative Writing Tecnique and students taught using Individual Writing Technique
