The Effect of Discovery Learning Model on Students’ Explanatory Text Writing Skills

This study aims to investigate the effect of discovery learning model to develop students’ writing ability of explanatory text of seventh grade students. This research used quasi experimental method with non-equivalent control group design. It consisted of experimental class and control class. The population in this study is class VII with a total of 256 students. In this study, the classes that were used as VII-1 as the experimental class and VII-2 as the control class. The results of the post-test calculation are the average of the experimental class and the control class, the normality test shows that the data is normally distributed and the homogeneity test results show that the data variance is homogeneous. Based on the results the experimental class post-test has an average value of 76.34 and the control class 70,15. The t test of the post-test data shows that αα = 0.05, t-count= 2,02>> t-table = 1,9989 meaning that H0 is rejected, meaning that there is a difference in the writing skills of explanatory texts students who are taught using the discovery learning model and students who are taught using conventional learning method.
