CHAPTER III THE RESEARCH METHODOLOGY
This chapter comprises the method of the research, the place and time of the research, the object of the research, the instruments, and the technique of data
collecting as well as its analysis.
A. The Method of the Research
The writer applies qualitative method on this research. Several characteristics of qualitative research according to Bogdan and Biklen are,
1 qualitative research has the natural setting as the direct source of data and researcher is the key instrument; 2 qualitative research is descriptive.

P P = Percentage
F = Frequency of error made N = Number of samples which is observed
32
The formula given above is used to count on the percentage of errors for each of the items followed by each student as the sample.
In order to know the average value of the errors committed by the students, the following formula is then applied:
P = P
: Percentage F
: Frequency of wrong answer N
: Number of Sample n
: Number of items
