CHAPTER III
RESEARCH METHODOLOGY
The writer elaborates the methodology of the research in this chapter mainly to put forward the rationale of using certain instrument as well as its
validity and reliability. It also provides the type of the research, data gathering procedure and data analysis procedure. Related literatures are reviewed as the
basis of the methodology to disclose accurate and reliable data.
A. Research Method
The method which was used in this research was a survey. Wiersma 1995:169 states that surveys are used to measure attitudes, opinions, or
achievements–any number of variables in natural setting. In line with Wiersma, Sprinthall, Schmutte and Sirois 1991: 93 add that survey research may be used
to investigate virtually anything that people do or think. Furthermore, one of the uses of survey information is to generalise the results to the population from
which the sample has been selected. In this research, survey was employed to measure the performance of the sixth semester students of English Language
Education of Sanata Dharma University on analysing the adjective clauses using X schema. The results of the research were used to generalise the students’
performance and to classify their mistakes on analysing the adjective clauses using the X schema. Seeing the nature of the survey and the objective of the
research it was appropriate to select survey as the method of the investigations.

B. Research Respondent
The population of the research was the students of the English Language Education of Sanata Dharma University academic year 20072008. The sample of
this research was the sixth semester students of English Language Education of Sanata Dharma University academic year of 20072008 class A. The writer chose
the sixth semester students because they had learned adjective clause in their previous structure courses before the research was conducted and they were
learning English Morpho-Syntax at the time the research was conducted. There were two Morpho-Syntax classes, class A and class B, in the
academic year 20072008. However, the writer conducted the research only in class A because of two reasons. First, considering the time and the affordability,
the writer could not investigate all of the population. Secondly, class A had finished discussing the topic of adjective clauses whereas class B had not. Seeing,
the conditions, class A was appropriate to be the sample of the research. In choosing the sample, the writer used cluster sampling procedure. As
stated by Wiersma 1999: 292, the cluster sampling is a procedure to choose the sample which involves the random selection of clusters from the bigger
population of clusters. This sampling method was chosen because of two reasons. The first was that this sampling method was easier to conduct since the writer did
not need to make new clusters. The second reason was that the sixth semester students of the English Language Education Study Program were supposed to
share the same level of performance on adjective clauses and syntax at the time the research was conducted. Therefore, the outcome of sample would yield similar

result. As a result, the writer conducted the research to the 45 students of Morpho- Syntax class A academic year 20072008.
