score which showed 12 for the highest score and 10 for the lowest score as the result in the gain score, it can be concluded that there was significant influence in teaching
speaking using information gap activities.
2. Controlled Class
In the controlled class the writer also gave the test. The results of the test as follow:

Based on table 4.2 above, it showed that the highest score in controlled class was 66 which is gotten from one student. Then, the lowest score in controlled class was
54 which is gotten by one student. From the differences between table 4.1 and 4.2 above, it showed that the experimental class is higher than the controlled class in the
posttest result, where experimental class has 86 as the highest score and the controlled class has 66 as the highest score. It can be concluded that there was a
positive influence of using information gap activities toward students’ speaking skill.
B. Analysis of the Data
After the writer found the difference between the gain score of experimental class and controlled class, then she make a comparison. Below is the result of comparison
of the experiment class and control class:
