Harris 1969: 69 states that “there are two kinds of test instrument used to measure the four-language skills of the students, namely the objective test and
the essay test.” For collecting the data I decided to use an essay test in the form of specific topic to be explored into hortatory exposition text because in this test
students can freely express their ideas in a written form. The instrument was interesting topics that can be explored becoming
hortatory exposition text. I chose the topics which were related to students‟ surroundings and their daily life. I also made the test based on the curriculum.
Thus, the content of the test offered in the research was valid enough.
3.7 Method of Collecting Data
There are some methods of collecting data used in a research. Here, in my research there were three methods of collecting data I used. The first was
documentation method, the second was experimental method through testing, and the last was questionnaire.
3.7.1 Documentation Method
This kind of method was used in order to gather data which had been provided. The data was called based data, taken from students‟ achievement or mark of
English subject. This data would be used to measure normality and homogeneity of research sample. By knowing the results, I could apply Purposive Random
Sampling as the suitable sampling technique because the population was homogeneous. Therefore in whatever class I applied my strategy, the result would
not change significantly.
3.7.2 Experimental Method
Experimental method here means that the data is gathered by doing experiment through test. There were two steps in gathering the data. The first was pre-test,
which the data was taken before giving treatments. The pre-test result was used as baseline data. Then the next was post-test. This test was done after treatments
given. Both these tests then would be analyzed through statistical design I would be explained later.
For the detail procedure of collecting these data, I would like to expose as follows:
1 Chose the eleventh grade students of Science Program of SMA Negeri 1
Sukoharjo in the academic year of 20102011 as the research population. 2
Decided the research sample as the experimental group through sampling technique that was XI-IA 4 Science Program of SMA Negeri 1
Sukoharjo. 3
Gave pre-test to the experimental group. 4
Mentioned the result of pre-test by applying analytic scale for rating composition tasks from Brown Bailey 1984 as quoted by Brown
2004: 244-245. I will explain this analytic scale later. 5
Applied the treatments of using One Stay Three Stay strategy toward the experimental group.
6 Conducted post-test toward the experimental group.
7 Gave the result of post-test based on the same step mentioned in number
4.
Besides data from pre-test and post-test, I also collected the data from students‟ ideas that had been written on a piece paper. The paper consists of list of
students‟ ideas after applying One Stay Three Stray strategy.
