3.6.2 Pre-Test
Pre test was conducted before I gave the treatment. This test has purpose to know the initial ability of the students especially in reading and writing hortatory
exposition text. This test consisted of two forms which were multiple choices and essay. The students would be asked to do the test in a given time 90 minutes.
The students who were asked to do the test were the students of both groups, experimental and control groups.
3.6.3 Treatment
After conducting the pre-test, the next steps in conducting the experimental was giving the treatments. Both groups were given the treatments, but there was a
prominent difference in the treatment itself. The experimental group got the treatment using CIRC method in reading and writing material. On the other hand,
the control group got the treatment using conventional technique.

3.6.4 Post-Test
This is the last steps in conducting the experiment. After administering the pre test and treatments, I must conduct the post test. This test aimed to know the students’
ability in reading and writing hortatory exposition text after getting the treatment.
3.7 Method of Analyzing Data
After getting the data, I had to analyze the data by using several ways. In this research, the method of data analyzing used were scoring technique and
classifying the score.
3.7.1 Scoring Technique
In this research, I would take the score of students in the form of multiple choice and essay. For the multiple choice items, the scoring was only counting the correct
answer discrete point test. In the other hand, in the writing test, I would take the score based on students’ writing production to measure the progress. The aspects
of the scoring writing are grammar, vocabulary, spelling, content, and fluency. There is the scoring technique of writing skills based on Heaton quoted by
Sutirah 2009: 30-2. Items
