hypothesized that if the principles of the Natural Method are the same as of the principles to acquire vocabulary, the Natural Method can improve vocabulary
mastery. The study of this research is intended to find evidence to support the hypothesis. The next part states some hypotheses of this research.
C. Hypotheses
There are three hypotheses in this study, namely conceptual hypothesis, operational hypothesis, and statistical hypothesis. They are stated as follow:
1. Conceptual Hypothesis There are two conceptual hypotheses:
1. The Natural Method improves vocabulary mastery of kindergarten students. 2. Natural Method gives contribution in providing comprehensible input,
optimal memorization and practice for real communication. 2. Operational Hypothesis
There is a positive significant difference between the t-value of the students taught using the Natural Method and that of students taught using traditional
method. 3. Statistical Hypothesis
Ho: e =c
Hi: e c
Note Ho = There is no significant difference between the t-value of the students
taught using the Natural Method and that of students taught using traditional method.
Hi = There is a positive significant difference between the t-value of the students taught using the Natural Method and that of students taught using
traditional method. e = the t-value of the experimental group
c = the t-value of the control group If there is a positive significant difference, it implies that the Natural Method
improves the students’ vocabulary mastery.

CHAPTER III RESEARCH METHODOLOGY
This chapter talks about the research implementation. The discussion includes research method, setting, subject, time allocation, research instrument,
research procedure, and technique of analyzing data.
A. Research Method
Experimental research was applied in this study to answer the problems as stated in the problem formulation. In this research, the writer used two groups,
one as the experimental group and the other as the control group. The students in the experimental group were taught using the experimental method which was in
this case using the Natural Method while in the control group, the students were taught using traditional method which usually used translation and memorization
drilling. The control group was taken as the comparison to the experimental group to see the effectiveness of the Natural Method.
In this research, there were two variables. Those variables were independent variable and dependent variable. Independent variable was the
treatment or manipulated variable that was presumed to have an effect on another variable while dependent variable referred to the variable that might be affected
by independent variable. In this research, the independent variable was the Natural Method and the traditional method that was applied in the experimental group and
the control group respectively. The dependent variable for the two groups was the same that was the students’ vocabulary achievement.
To answer the first problem, the writer conducted pre test before applying the treatment to see the level of the students’ ability of both groups. After the
treatment had been done, post test was conducted to see the improvement of the students’ vocabulary achievement. Meanwhile, to answer the second problem, the
writer used observation check list during the treatment for both groups to see the contributions of the methods to improve vocabulary acquisition. Further
explanation of this analysis will be discussed further in Chapter IV.
B. Setting
In order to see whether or not the Natural Method improves the children’s vocabulary mastery, the experimental research in this study was conducted at TK
Indriyasana Baciro. The writer chose the school as the place for doing the research because the school had two classes in the same number of students with equal age;
therefore the class was expected to have almost equal ability. Furthermore, the students were introduced English only from their class teacher in limited topic and
vocabulary.
C. Subject
The subjects of this research were the first grade students of TK Indriyasana Baciro. In this research, the writer needed two presumably equivalent
groups. Since there were two classes with the same range of age in the Kindergarten which were expected to have similar ability, the writer chose the
classes to be the subjects of this research. Pre-test was conducted to see the language proficiency of the students. The total number of the students was 56; 28
