Abstract

This research was a quasi experimental design with non-equivalent group post test only design. The purpose of this research was to know whether or not there was a significant effect of using Single Pictures on the eighth grades students’ descriptive text writing ability at SMPN 4 Rogojampi Satu Atap. The population of this research was all of the eighth year students of SMPN 4 Rogojampi Satu Atap in the 2014/2015 academic year. Homogeneity analysis was done to know the homogeneity of the population and determine the research samples. The data analyzed were the results of the previous semester score from the English teacher. They were analyzed by ANOVA formula with SPSS and the result showed that the significant value is 0.000 which is definitely lower than 0.05. It means that the classes were heterogeneous, which also means that the students’ ability was various. Therefore, two classes with similar level of ability were selected based on the nearest mean score as representative of the population in this research. The two classes chosen were 8B with means score 73.13 and 8D with mean score 73.33. Lottery was applied to decide which class between 8B and 8D that became the experimental class or the control class. From the lottery, class 8B was chosen as the control class that was taught writing without using single picture and class 8D as the experimental class that was taught writing by using single picture. The total number of respondents was 60. Both of the respondents of the experimental class and the control class students were 30. The data of this research were collected from the students’ scores of writing achievement test, interview and documentation. The students’ writing achievement was collected from the writing test to make comparison between the two groups after the treatment done. The results of the research were analyzed by using independent sample t-test on SPSS (Statistical Package of Social Science). Based on the computation, the mean score of the experimental group was higher than the control group. It was 70.3333 for experimental group and 51.6667 for the control group. The Significant (2-tailed) column shows 0.000 value, which is lower than 0.05. It means that the null hypothesis “There is no significant effect using single picture on the eighth grade student was rejected. Consequently, the alternative hypothesis, that “there is a significant effect of using Single Picture on the eighth grade student’s descriptive text writing achievement at SMP Negeri 4 Rogojampi Satu Atap” was accepted. The result research proved that there was a significant effect of using Single Pictures on the eighth grades students’ descriptive text writing ability at SMPN 4 Rogojampi Satu Atap in the 2014/2015 academic year.
