3.5 Pilot Study
Pilot study was implemented in this research in order to measure the validity and reliability of the instruments.
A pilot study can be used as “a small scale version or trial run in preparation for a major study” Polit, Beck, and Hungler,
2001 as cited in Simon, 2011. In this research, the pilot study was conducted by involving three students. They were the students of English Language Studies of
Sanata Dharma University. It aimed to to check whether the instruments were comprehensible and usable.
The three instruments were pilot-tested before they were given to the sample of the research. The results of conducting the pilot study were two revisions on
the instruments. First, the total number of reading comprehension tests was decreased from 50 items became 25 items in order to make the sample easier and
faster to do the test. Second, several inappropriate words were changed to be better and more comprehensible.
