3.4.2 Pre-test
Pre-test was conducted in the beginning of the research. In this research, I gave a pre-test for both two classes. I gave the pre-test to know the stude
nts‟ ability in writing recount text before implementing the treatment. During this
session, the students had to write a recount story. I gave them a short explanation about recount text and after that the students had to make a recount text based on
their experiences. Then, I collected the score as the data for the research.
3.4.3 Post-test
Post-test was conducted after the treatment. The post-test was given after conducting all the activities. I gave the same type of the test as pre-test. Post-test
wa s used to measure the students‟ achievement after the treatment was given.

3.4.4 Questionnaires
Questionnaire was given to the students after they finished doing the post- test. There were five questions used to analyze
the students‟ interest, advantage, achievement, relevancy, and difficulty in teaching and learning process by using
guided writing technique. According to Nunan 1992:143 questionnaire items can be closed or open
ended. A closed item is the researcher provide the possible responses. Meanwhile, an open item is the subject decide what to say by themselves. Responding a closed
item is easier than an open item. In addition, the researcher can easily compare and analyse the answer easier when using closed items. In this research, I used a
closed items that had five questions with three possible answers for each questions. Each option was given a score that showed the quality of each
indicator. The score range was from 1 to 3 as shown in table bellow:
Table 3.1 The Score Range Options

A 1
B 2
C 3
To see the mean of the questionnaire results, this formula was used:

M = mean
∑x = the sum of the item score
N = the number of the students
