Abstract:
The objective of this research was to find out the significant effect of RAFT
strategy assisted by graphic images on the students‟ achievement in writing. The
Research used in this study was an experimental research. This research design
was conducted at SMA Al-ULUM Medan, located on Jalan Tuasan No.35,
Kecamatan Medan Tembung. The population of this research was the eleven
grade classes in academic year 2016/2017 which consisted of 2 classes, 51
students. The researcher took two classes by using total random sampling, XI-IPS
was as the control class that consisted of 22 students and XI IPA was as the
experimental class which involved 29 students. Each class was given a pre-test,
treatment, and post-test. The control class was taught by using lecture method
meanwhile the experimental class was treated by using RAFT strategy. The
instrument of this research was written test. The data were analyzed by using t-test
formula. Then, the result showed that tobserve (1.76) was higher than ttable (1.67)
with the degree of freedom (df = 49) for two-tailed test (1.76 >1.67). It meant that
the null hypothesis (Ho) was rejected and alternative hypothesis (Ha) was
accepted. In conclusion, there was the significant effect on the students‟
achievement in writing by using RAFT Strategy Assisted by Graphic Images
