THE EFFECT OF MIND MAPPING TECHNIQUE ON STUDENTS WRITING ACHIEVEMENT IN NARRATIVE TEXT

This study aims to discover the effect of Mind Mapping Technique on Student’s Writing Achievement in Narrative Text. It was conducted by using experimental research design. The population of this research was tenth (X) grade students of MAN 2 Model Medan. The samples of the research were two classes divided into two groups, experimental and control group which were chosen by using random sampling technique. The first group is 32 students (X-9) which was the experimental group and the second group is 32 students (X-10) which was the control group. The experimental group was taught by using mind mapping technique the control group was taught by using Lecture Method. The instrument for collecting the data was a writing test which only consist of one item. Inter-rater reliability formula was applied to obtain the reliability of the test. Based on the calculation, it shows that the reliability of the test was 0,98. Then, after analyzing the data, it was found that the value of to was 8,108 with the degree of freedom (df)=62 at the level of significance p(0,05) = 2,000. It means that to is higher than tt (8,108 > 2,000). The result of this study shows that Mind Mapping Technique has a significant effect on students’ writing achievement in narrative text.
