CHAPTER IV RESEARCH RESULTS AND DISCUSSION
In this chapter the researcher would like to present and elaborate the research findings in details. The researcher started by choosing the subjects of the
research to be the eighth graders of SMP Negeri 15 Yogyakarta. The research data were collected using two tests, pretest and posttest which was conducted at the
beginning of the meetings and at the end of the process of experimentation consecutively, and the questionnaire which was filled out by the students after the
research subjects got the experimentation of learning the nature of the guessing meaning from context procedure. While the observation was filled out by the
observer during the learning process. The researcher used these data to answer the research questions stated in the first chapter of this research. This chapter is
divided into two parts. In the first part the researcher discusses how effective is guessing meaning from context procedure if implemented in vocabulary learning
to the eighth graders of SMP Negeri 15 Yogyakarta after having experimentation during specific time periods. In the second part of the chapter, the researcher

A. The Implementation of Guessing Meaning from Context Procedure for
Vocabulary Learning in Class 8A of SMP Negeri 15 Yogyakarta
In this research the researcher began the study by choosing the subjects, who were the students of class 8A of SMP Negeri 15 Yogyakarta. According to Johnson‟s
1992 procedure for experimental research especially for a one group pretest- posttest design, there was no need to assign the subjects to groups because the
research required only one group of subjects. The researcher took class 8A as the research study in six meetings. There were some reasons during the process for
choosing the subjects. First, class 8A is one of classes that consists of students who have a higher degree of capability than the other class of eighth graders of
SMP Negeri 15 Yogyakarta. The second reason was about the limitation of time, which was six meetings with a pretest, treatment and posttest. As the school
schedule permitted, there were only those limited times which were available. As a result, the researcher used the time effectively.
Before having pretest and posttest, the researcher administered pilot test. This pilot test is for examining whether the pretest and posttest questions was not
difficult and appropriate for them. The researcher took five students from different class, they are students from class 8 B. From the result of the pretest and posttest
showed that three out of five students‟ score was above six for the pretest and six
in the posttest. As well as the researcher also had observer during the process. The researcher used naturalistic observation so that the behavior can be observed in
naturalistic situations Ary, Jacobs, Sorensen, 2010, p. 433 PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI
