As Table 4 shows that in pre-test (matching test) exam there were 10 questions and comprehension questions were also 10. Experimental group’s mean of the scores for the first matching test was 7.6 out of 10 and control group’s was 7.2. In the next part(comprehension questions) EG shows again 7.6 while CG shows 7 point. In both tests experimental group gained more scores than CG (7,2<7,6; 7<7,6). The difference between mean indicates 0,4 and 0,6 points. The difference is obvious from the beginning part.



Figure 1. Reflection of pre-test results

As Figure 1 shows, Experimental group’s results of pre-test were lower (4%) than CG results. In this step, the rating score raised.

As tables 5 ad 6 demonstrate that there is no difference between dispersions (individual), however in central tendency EG shows a higher result. (mode, median: 8>7) .


In the following diagram we will show the comparison of both groups.
Figure 2. Reflection of central tendency

The scoring of filling the gaps exercise was also done by giving one point to each correct answer as previous tasks. Since there were 10 questions, total score was 10. For this task, the means, mode, range of each group were calculated. Then, two groups were compared to see if there were differences among them.


Table 7. contains the means and the standard deviations of the immediate multiple-choice tests.

Figure 3. The reflection of results (gap-filling exercise)

As Figure 3 shows the difference of mean in both groups is visible. EG’s mean is 7,4 and CG’s mean is 6,9. (7,4>6,9). This data indicates the rating position of Experimental group’s results since in previous tasks the score of difference was 0,4 and this time it indicates 0,5 (5%). (0,4<0,5).


The next step was 1 post test-multiple choice test and it includes 20 questions and scores were calculated by giving one point in each answer (20 points). The 2 post was definition sentence test and it also includes 20 questions by giving one point to each correct answer. In the following tables, reader can get information about the results of post-tests (multiple-choice and definition sentence test) and the comparison of them in both groups.
