The Effect of Clustering Technique on Students’ Achievement in Writing Analytical Exposition.

Abstract

This study was attempted to investigate the effect of clustering technique on students’ achievement in writing analytical exposition. The method used in this study was experimental research design. This research had been conducted at MAN 1 Medan Jalan William Iskandar No. 7B, Bantan Tim, Medan Tembung, Kota Medan, Sumatera Utara. The population of this research were the second grade in academic 2017/2018 which consisted of thirteen classes, the reseacher took 2 classes by using cluster random sampling, XI MIA I was as the experimental class that consisted of 46 students and XI MIA II was as the control class which involved 46 students. Each class was given a pre-test, treatment, and post-test. The control class was taught by using conventional method meanwhile the experimental class was treated by using Clustering Technique. The instrument of this research was written test. The data were analyzed by using t-test formula. Then, the result showed that tobserve (3.22) was higher than ttable (1.99) with the degree of freedom (df=90). It meant that the null hypothesis (Ho) was rejected and alternative hypothesis (Ha) was accepted. In conclusion, there was the significant effect on students’ achievement in writing analytical exposition by using clustering technique.
