b. Result of Homogeneity Test

Homogeneity test is used to determine whether the data obtained from the sample homogeneous or not. The Hypotheses are : H o = the variance of the data is homogenous H a = the variance of the data is not homogenous The criteria of acceptance are : H o is accepted if F observed is lower than F critical , it means that the variance of the data is homogenous. H o is refused if F observed is lower than F critical , it means that the variance of the data is heterogeneous. To measure the homogeneity test of control class, the researcher used the formula as follows : F observed = the biggest variants the smallest variants The result of homogeneity is : Variance S2 of Pre test control class : 25.1 Variance S2 of Pre test experimental class : 26.72 F observed = 26.72 = 1.06 25.1 Table 7 Homogeneity The Result of Pre-Test and Post-test In the control and Experimental Class Class Variance F observed F critical Conclusion Control 25.1 1,06 1,98 Homogeneous Experimental 26.72 From the data gained homogeneity test for pre-test and post-test was 1.06. From the result of homogeneity was consulted to fisher table, it was found that F critical of 0.05 25,24= 1.98. The data come from homogenous data provided F observed is lower than Fcritical F observed F critical . See Appendix 18

2. Result of Hypothetical Test

The researcher used the following t-test by independent t-test for hypothectical of test. The hypotheses are : H o : There is no significant influence of using dictogloss technique toward students‟s analytical exposition text writing ability at the first semester of eleventh grade of SMA Karya Mataram South Lampung in the academic year of 20162017. H a : There is a significant influence of using dictogloss technique toward students‟s analytical exposition text writing ability at the first semester of eleventh grade of SMA Karya Mataram South Lampung in the academic year of 20162017. The criteria of the test are as follows : H a is accapted if T observed is higher than T critical , or T observed T critical H a is refused if T observed is higher than T critical , or T observed T critical Table 8 T-test of Pre-test and Post-test in Experimental Class and Control Class Pre-test and Post-test N T observed T critical Conclusion 49 5.80 2.02 Significant Difference

E. Discussion

The research result has shown that there is significant influence of using dictogloss technique towards‟ students ability in analytical exposition text. From the result above, it can be seen that the average score of students‟ writing ability in analytical exposition text who are taught by using dictogloss technique is higher than those who are taught using free writing technique. The result showed that the average score control class was 58.3 and the average score of experimental class was 57.7. The normality and homogeneity test were show that the data were homogenous and normal. Therefore, it can be concluded that the two groups, experimental class and control class had the same ability at the beginning of the research. Afterward, the students were taught by using dictogloss technique in the experimental class and using free writing technique in control class. The material was three topics about analytical exposition for three treatments. At the end of the research, post-test was given to measure the improvement of students‟ writing ability in analytical exposition text in both classes after treatments done. The result of post-test showed that two classes got improvement. It was proved by increasing average both classes. The average score of control class was the begining, the pre-test was administer ed to how the students‟ writing ability in analytical exposition text before they were given treatments by the researcher. The result showed that the average score of control class was 70.6 and the average score in the experimental class was 78.4. The way to encourage the students to be more active in teaching and learning process, the teacher should apply a method, a strategy or a technique. Therefore, the teaching writing would be more effective and would be make students be more active in the class if the teacher used helpful and interesting technique. Due to using Dictogloss
