From the table above it is known the students’ response toward the learning activity that had done shows almost all students agree to the
teacher’s professionalism and performance during the learning activities. They also admitted that they got more interested to use portfolio
assessment technique to improve their achievement in past continuous tense.
C. The Result of Post Test
For the need of the research, the writer had done the trustworthiness of the test using the construct validity. It was done before the students carried out the
tests. The following table presents the result of data including the pre test, post test 1, and post test 2.

The writer used some steps to compare the result between pre test and post test of each cycle. The steps are calculating the students mean score of the test,
calculating the class percentage, and calculating the students’ improvement score from pre test to post test 1 and 2 into percentage.
To analyze the data of pre test, the first step is to get the mean score of the class. The following is the calculation:
= 2210 40
= 55.25 From the computation above, it is known that the mean score of the class
in pre test is 55.25 which mean the students’ score of past continuous tense test
before using portfolio assessment technique or before implementing CAR is 55.25.
Then, to know the percentage of students’ score who achieved the KKM 65 the writer uses the calculation as follow:
P = F x 100 N
P = 14 x 100 40
P = 35 From that calculation, the students’ score percentage in the pre test is 35 that
means there are 14 students who achieved the KKM score ≥ 65 and there are 26
students are below the KKM score ≥ 65.
After calculating the result of post test 1 in the cycle 1 of CAR, the writer calculates the students’ score improvement from the pre test result. There are three
steps to know this improvement. The steps are calculating the students’ mean score of the class, calculating the students’ improvement score into percentage
and calculating the class percentage.
66
The first step is calculating the mean score of post test 1. The following is the calculation:
= 2815 40
= 70.38 Based on the calculation, the students’ mean score of post test is 70.38. It shows
that there are some improvements from the pre test mean score. It can be seen from the pre test mean score 55.25 to the mean score of post test 1 70.38. It
improves 15.13 70.38 – 55.25.
The second step is the calculation to get the percentage of students’
improvement score from pre test to post test 1. The writer uses the computation as follow:
P = 70.38 – 55.25 x 100
55.25 P = 27.38
From that computation, the percentage of the students’ improvement score from pre test to post test 1 is 27.38. It indicates that the score in the cycle 1 has
improved 27.38 from the pre test score. The third step is to know the percentage of students who achieved the
KKM. The following is the calculation: P = x 100
P = 31 x 100 40
= 77.5
67
Based on the calculation, the class percentage which achieved the KKM is 77.5. It means there are 31 students who achieved the KKM and there are 9
students whose score are below the KKM. The class percentage of post test 1 proves that there is a significant improvement of the class percentage in the pre
test 35 . The improvement of the students’ percentage who achieved the KKM
is 42.5 77.5. – 35 . Nevertheless, the improvements of the class percentage
are still below the target of success CAR. Therefore, it is still needed more effort and improvement to achieve the target.
Next in the cycle 2 of CAR, the writer also calculates the result of the post test 2 to know further the score improvement either from the result of pre test or
post test 1. There are three steps in order to know this improvement. The steps are to calculate the mean score of the class, to calculate the percentage of the
stu dents’ improvement score, and to calculate the class percentage which pass the
KKM score ≥ 65.
The first step is to calculate the mean score of the class in post test 2. The following is the calculation:
X = 3250 40
= 81.25 Based on the calculation, the mean score of post test 2 is 81.25 which
means there are some students’ improvement score 10.87 from the mean score of post test 1 70.38.
The second step is to know the calculation of the percentage of students’ improvement score. It uses the calculation as following:
P = 81.25 - 55.25 x 100 55.25
68
P = 47.06 From the calculation above, it could be seen that the post test 2 improves
47.06 from the pre test or 19.68 from the post test 1 47.06 - 27.38. The last step is to know the class percentage whose score achieved the
KKM. Here, the writer computes by using as follows: P = x 100
P = 37 x 100 40
P = 92.5 From the computation above, the class percentage is 92.5 . It means that
in the cycle 2 there are 37 students who achieve the KKM and there are only 3 students are below the KKM. The class percentage of post test 2 proves some
improvements from the previous test. The improvement is 57.5 from the pre test 35 or 15 from the post test 1 77.5. The following chart presents the
improvements of the class percentage.
