From that calculation, the mean score of the class in post-test 2 showed the valuably improvement, it is 91.41.
To calculate the percentage of students‟ improvement of pronunciation test score between pre-test and post-test 2, the writer
computes as follows: P= y2-y x 100
y P= 91.41-68.21 x 100
68.21 P= 23.2 x 100
68.21
P= 34.01
From that computation, it can be seen that the students‟ mean score of post-test 2 showed the higher improvement than the comparison of
mean score in post-test 1, the percentage is 34.01.
D. The Interpretation of Test Result
The interpretation of the data results among pre-test, the pos-test of cycle 1
and the post-test of cycle 2 as follows:
In the pre-test, the mean score of students on pronunciation test before using CAR and applying minimal pair drill in teaching pronunciation is 68.21.
This mean score is viewed low because the minimal standard-mean score that the teacher declared is 70 seventy. So, mean score 68.21 is assumed as the low score
achievement. Afterwards, to compare whether CAR succeed or not, it was done post-test that is carried out after implementing CAR for each cycle. The result of
mean score in the post-test cycle 1 is 82.05. This is assumed as good achievement- mean score that the students got because they could pass the minimal standard
score that the teacher declared. It can be said that the students‟ mean score from
the pre-test to post-test improved. The improvement is 82.05-68.21 = 13.84 or the
improvement percentage is 20.29. However, from this percentage, the CAR has
51
been failed. Because the criterion of the action success based on the writer and the teacher‟s agreement is 30.
Furthermore, the mean score of post-test 2 is 91.41. It can be said that the students showed their best achievement. They proved the good improvement for
each cycle. The percentage of mean score improvement between pre-test and post- test 2 is 34.01. From that percentage, it can be concluded that the CAR is
success because the percentage of students‟ mean score of post-test 2 could pass the criterion of CAR success, 30. So, the writer and the teacher agreed that the
cycle of CAR is stopped.
