Qualitative data was obtained from observation checklist and field notes during the learning process in the classroom. While quantitative data was obtained from students' reading tests. In this study there were Cycle I and Cycle II, each cycle consisted of 2 sessions. The average reading test score of the students in Cycle I was 72, which was then continued in Cycle II so that there was an increase in the average reading comprehension test score to 89.
