D. The Result of the Questionnaire
To know the students’ response toward the teaching learning activity during CAR, the writer provided a questionnaire that consists of 25 questions in
four scales answer. The calculation of the result of the questionnaire the writer had done several steps as follow:
a. First, the writer tabulated the frequency of the answer on each question. b. Second, the writer calculated the percentage of the answer using the
formula:
c. After getting the percentage of the answer of each question, the writer tabulated the percentage of the answer based on the indicators.
d. Then, after comparing the tabulation of those answers, the writer analyzed the evaluation of the indicators which is aimed to know the category of the
respondent. Then, the result can be seen as follow: Questionnaire Strength indicator 1
= x 100
= 1527 x 100 1920
= 79.5
Questionnaire Strength indicator 2 =
x 100 = 1638
x 100 2080
= 78.75
Based on the calculation above, it proves that the response of the students toward the teacher professionalism and their interest in learning past continuous
tense by using portfolio assessment technique is 79.5 and 78.75 that means it falls into the strong category.

E. The Interpretation after CAR
The interpretation of the test result and portfolio assessment result is divided into two parts. The first part is the interpretation of the result among the
pre test, the post test on cycle 1 and the post test cycle 2. The second one is the interpretation of the portfolio score
related to the students’ achievement. Here is the explanation:
The mean score of the pre test or the students’ score on the past continuous tense test before carrying out CAR is 55.25
. It is the students’ score on the past continuous tense before using portfolio assessment technique. In the other hand,
the class percentage which achieves the KKM is 35. It means that there are only 14 students who are able to achieve the KKM score
≥ 65 and there are 26 students whose score are below the KKM.
Next, the mean score in the post test of cycle 1 is 70.38. It shows the students’ score improvements from the pre test that is 15.13 70.38 – 55.25 or
27.38. Meanwhile the class percentage which achieves the KKM in post test 1 is 77.5. It indicates there are 31 students who achieved the KKM and there are 9
students are still out of target. Even though the improvement already shown a significant number, it is still under the target which is 80 of the students or at
least 32 students could achieve the KKM score ≥ 65.
In cycle 1, portfolio assignments are not success yet. It proves with the students’ score that cannot achieve the criteria of action success. There is only 1
student who gets the highest score in cycle 1 2.5. Students who get good category are 21 52.5. There are 16 students get medium category 40 and 2
students get bad category 5. The average of students’ achievement is 69.60. It is still under the target which is 90 of students or at least 36 students could
reach the achievement 70 which is showed from final portfolio score. It is needed more efforts and improvement in order to achieve the target of success CAR.
Hence, the teacher and the writer move on the next cycle of CAR. Then, the mean score in the post test of cycle 2 is 81.25 that means there
are some students’ score improvements 10.87 81.25 – 70.38 from the post test 1 or 47.06
students’ improvement in the score percentage from the pre test or
71
27.38 students’ improvement from the post test 1. Furthermore, students’ N gain
score is improving in each cycle in which 0.34 in the cycle 1 to 0.59 in the cycle 2. Otherwise, the class percentage which achieved the KKM is 92.5. It means
there are 37 students whose score achieve the KKM and there are 3 students only whose score still below the KKM. This class percentage indicates some
improvements that is 57.5 from the pre test 35 or 15 from the post test 1 77.5. The post test of cycle 2 has fulfilled the target of CAR success, that is
above 80 students could achieve the KKM. Therefore, in portfolio score, there are 10 students who get very good
category 25. Students who get good category are 30 75 and student who get medium category is 1 2.5. There are no students who get the category bad
and too bad. The average of s tudents’ achievement is 81.5. As a conclusion,
portfolio assignment is done successfully. It proves with the percentage students who get the score above 70 is 97.5. Then, the score proves the successful
indicator can be reached. Therefore, the CAR can be said success and the cycle of CAR is not continued.

CHAPTER V CONCLUSION AND SUGGESTION
A. Conclusion
Based on the result of the study that has been done toward the effectiveness of portfolio assessment technique to improve students’ achievement
in the Past Continuous Tense, the writer concludes some aspects as follows: 1.
The average of students’ final portfolio is improved from cycle 1 to cycle 2, with the score 69.60 medium category in cycle 1 and 81.35 good category
in cycle 2. As stated in the criteria of the action success that portfolio assessment can be a
measurement of students’ achievement. 2. The percentage of students who achieve the portfolio final score
≥ 70 is significant improvement. It improves from 55 or 12 students who achieved
portfolio final score ≥ 70 in cycle 1 to 97.5 or 39 students who achieved
portfolio score ≥ 70 in cycle 2.
3. The average of students’ improvement on understanding Past Continuous
Tense is improved. It proves with the mean score in post test 1 and post test 2 where the score is 70.38 in cycle 1 and 81.25 in cycle 2.
4. The average of N gain score from the pre test, post test 1 and post test 2 is developed from 0.34 in cycle 1 to 0.59 in cycle 2 that fall into medium
category. 5. The percentage
of students’ improvement on understanding Past Continuous Tense is improved from 77.5 to 92.5. It means CAR is successfully done
