THE EFFECT OF CONCEPT MAPPING STRATEGY ON STUDENTS’ READING COMPREHENSION ACHIEVEMENT IN DESCRIPTIVE TEXT

This study deals with the effect of Concept Mapping strategy on students’ reading comprehension achievement in descriptive text. This study is inspired by the problem that students’ faced at the school in terms of reading skill. This study was conducted by using experimental design to examine the effect of Concept Mapping strategy on students’ reading comprehension achievement in descriptive text. The subject of the study was the eighth grader in the first semester at SMP SWASTA Al- Washliyah Medan. They were chosen as the sample by applying random sampling. They were 64 students which is divided into two groups. Experimental group was taught by applying Concept Mapping strategy while the control group was taught by applying KWL chart strategy. The data of this research were taken from the students’ score of reading test. Based on the calculation showed that the coefficient of the test was 0.9, it shows that the test is highly reliable. There were two data used in this research. They were pre-test and post-test. The data were analyzed by using t-test formula to show the effect of Concept Mapping strategy on students’ reading comprehension achievement in descriptive text. After analyzing the data, the finding indicates that t-observed was higher than t-table (2.8 > 2.000) at the level significant 0.05 with the degree of freedom (df) 58.
