Reliability deals with the issue of fairness to all candidates. The researcher should consider if the research procedures used by Researcher A are exactly followed by
Researcher B, the results will be the same each time?Wallace, 1998: 36. Reliability is important for any test. A test will be reliable if it is held many times
approximately the same result will be obtained. To measure the reliability, the formula which is used is as follows:
1 1
∑
2
Where : = The reliability of the instrument
= The number of valid item
B. The Technique of Data Analysis
There are qualitative and quantitative ways in analyzing data: 1.
Qualitative In analyzing the data in the form of qualitative, the writer will use Constant
Comparative Method as suggested by Strauss and Glasser in Moleong 2004: 288- 289. They state that in general, the data analysis process includes data reduction,
data classification, and data synthesis. They are as follows:
commit to user a. Data Reduction
1 Unit identification. First, the smallest unit that is found in the data is identified. It must have close relationship with the research problems.
2 Having got the unit, the next step is making codification. It means that we have to code every unit in order to know where the data come from.
b. Data Classification 1 Categorization arrangement. It is aimed at choosing every unit that has the
same characteristics. 2 Every category must be labeled.
c. Data Synthesis 1 To synthesis means to look for the relationship between one category to the
others. 2 Then related one category to the others must be given a label again.
2. Quantitative
To analyze the test quantitative data, the writer compares the mean score of the pre test and post test.The mean of the pre test and post test can be
calculated with the formulas as follows:
N X

Y Y

In which:
X
= Means of pre-test scores

Y

Furchan 2004:158 Finally, by analyzing the observation and the test result, the researcher
can make the conclusion whether word webs can improve the students’ vocabulary mastery or not.

CHAPTER IV RESEARCH FINDING AND DISCUSSION
This chapter discusses the result of research. Here, the researcher describes some findings and discussions about the implementation of the use of word webs to
improve student’s vocabulary mastery. There are some objectives of the research. They are as follows:
1. To identify the improvement of students’ vocabulary mastery in the third grade students of SDN Sidorejo Lor 1 Salatiga after implementing word webs in
teaching vocabulary. 2. To find the phenomenon that takes place when the teacher teaches vocabulary
through word webs. 3. To evaluate the strengths and weaknesses of implementing word webs in teaching
vocabulary. Before conducting the research, the researcher does pre-research to identify
the problem faced by the students. The research is conducted in two cycles. Every cycle in this research consists of series of steps, namely identifying the problems,
planning the action, implementing the action, observing or monitoring the action, reflecting the result of the observation, and revising the plan.
