4.2.5 Test of Significance

To check whether or not difference between the two means of the experimental group and the control group is statistically significant, t-value should be consulted with the critical value in the t-table. In this experiment, the number of subject of both the experimental group and the control group was 68. The degree of freedom was 66. The critical value with the degree of freedom 66 at the 5 alpha level of significant is 1.67. The t- value is higher than critical value 4.863 1.67. It can be concluded that there is a significant difference of the post-test result between the experimental group and the control one. Therefore, the hypothesis that “there is no significant difference in achievement between students who were taught writing narrative text using animation movies and those who were taught writing narrative text by using conventional method ” was refused. Based on the computation of the students ’ scores, the writer can conclude the fact as stated bellow. In the pre-test, the average scores of the experimental group and the control group were 47.74 and 46.79. From the pre-test, it can be said that the ability of the two groups was relatively the same. After they received the treatment, the average score of the experimental group was higher than the control group. The experimental group got 62.65 and the control group got 53.15. From the scores, it can be concluded that the two groups were homogenous, because there was only slight difference in the pre-test result between the experimental group and the control one. After receiving the different treatments, the score of the experimental group was higher than the score of the control group. In teaching narrative text to the experimental group, the writer used animation movies as a medium, where in the control group, the writer taught the students by using conventional method. The scores of experimental and control groups could prove that teaching written narrative text using animation movies as a medium to the tenth grade students of Senior High School was more effective.
