Abstract

Abstract
This study aims to discover the effect of applying Four Square Graphic Organizer
on students’ achievement in writing descriptive text. It was conducted by using
experimental research design. The population of this research was the seventh
(VII) grade students of SMP Sultan Iskandar Muda Medan with four parallel
classes. The samples of the research were two classes divided into two groups,
experimental and control group which were chosen by using random sampling
technique. Fifty students were taken as the samples. The experimental group was
taught by using Four Square Graphic Organizer, while the control group was
taught by using freewriting technique. The instrument for collecting the data was a
writing test. Pearson Product Moment formula was applied to obtain the reliability
of the test. Based on the calculation, it shows that the reliability of the test was
0,84 categorized as high reliability. Then, after analyzing the data, it was found
that the value of tobserved was 3,66 with the degree of freedom (df)=48 at the level
of significance p(0,05) = 2,01. It means that tobserved is higher than ttable (3,66 >
2,01). The result of this study shows that Four Square Graphic Organizer has a
significant effect on students’ achievement in writing descriptive text.
