3. The Students’ Scores
In this research, the students’ writing skills were scored from pre-test, progress test, and post-test to analyse their improvement. The researcher used
intra-rater reliability. So, the scoring was done by the researcher herself. Although it was just conducted by the researcher herself, it did not cut down the concept of
objectivity. In conducting the scoring using intra-rater reliability, the researcher first
read al l the students’ works, and then she scored it. To make the result more
reliable, the researcher made a rank on the student’s works and re-read it again. When the researcher felt that one’s work was better than the other, she will re-read
it carefully and might change the score. To get the time triangulation, the data were collected at three different
points of time; in the beginning, in the middle, and in the end of the research. In the beginning known as the pre-test, in the middle was the progress test, and in the
end was the post-test.
a. Task Weight
After the scores were obtained, a comparison of mean was held. There were three tasks in the test. The detail of the scoring is presented in the table
below.

Task Weight
1 30
2 30
3 40
TOTAL 100
Task 1 and Task 2’s weight are 30 each because in those tasks, the students are given guidance. For the Task 3, the researcher gives 40 because
there is no guidance. The comparison of the mean’s value of the pre-test, progress test, and post-test are presented below.
b. Mean Value Comparison
Mean value comparison is comparing the mean value of each tasks’ final score. By analysing this score, the improvement of each cycle will be seen.

Progress Test

To sum up, CF using direct feedback was successful used in Cycle I. The students’ mean value in pre-test from 26.74 improved to 45.89 in the progress test
which mean it increases 19.15 point. Furthermore, Cycle II was held. The score in the Post test are being
compared with the mean value of the progress test as explained below.

10.02 After the Cycle II was conducted, although the students’ mean value
increased, the improvement was not as many as after the Cycle I . The students’
mean value in progress test was 45.89 points and 55.91 in the post-test. So that, the students’ mean’s improvement in post-test is 10.02 points.
c. Mean Value Comparison on Five Components
There are also a mean value comparison on five components. It is comparing the average score of each component in every cycle. The table below
shows the comparison between the students’ mean score on five components in
pre-test and progress test.

Components in Pre-Test and Progress Test

The table above shows the improvement in the students’ score after the Cycle I was held. The biggest improvement is the organisation with 4.84 points,
followed by mechanics 3.90 points, style 3.60 points, grammar 3.58 points and the smallest is content with 2.50 points.
84 After that, an analysis of the five writing components after Cycle II is also
held. It is presented in the table below.

Different with after the first cycle, grammar gets the biggest score with 2.26 points followed by organisation with 2.24 points, style 2.09 points, content
2.04 points and the smallest is mechanics, 1.26 points.
