2. Second step The teacher reads a text or dialogue to students and asks them to listen what teacher reads.
And then, they are asked to find the difficult words, from the text or the dialogue and write them in their books.
3. Third step After they write the difficult words in their books, ask for volunteers to write them on the
white board, and check their spelling and pronunciation.
D. Data Collection
The data used in this study are information about the kind of visual media and their effectiveness. Collecting data is one important thing in the research, that can be determined the result
of the research such as:
1. Observation
Observation is held to collect data about the use and development of visual media. The writer did three times of observation. This observation is done to know the students’ attitude in learning
English by using visual media and how the teacher teaches English.
2. Interview
Interview is done to collect data from teachers. The data, which is gotten through interview, are information about the use of visual media by the English teachers and their response about the visual media that is developed by the
writer.
D. Test
The test is made by the writer. He takes the question from two books. First, “Competency based English 1” by Tony Rogers and second “Speak English First 1” by Chabib Basirun.
The test is given to the students in the last of the semester. It is given to the students in two times. First, the writer gives “pre-test” to know about their competency in English before they are
taught by using visual media. Second, he gives “post-test” which is held in the last of the semester.
Both of tests are held to know their mastery of the materials at first semester. The test consists of two kinds, multiple choice and essay.
The writer gives the test to 40 students, 20 students from controlled class and 20 students from experiment class, the test consist of 15 items that related to the English themes, it is divided in
two forms, and they are multiple choice and essay. Multiple choice consists of 15 items, from number 1 to number fifteen, its score in one item is
4 four, it means, if the students can answer the question correctly, he will get 4 scores, and if he can choose the answer of 15 items correctly, he will get 60 scores.
Essay consists of 5 items, its score in one item is 8 eight, it means if the students can answer one item correctly, they will get 8 scores, and if they can answer 5 items correctly, they will get 40
scores. From the description of each test above, we can see that the highest score of this test is 100
scores.
E. Data Analysis
After getting the data either from control class and experiment class, the writer analyzes it by using statistic calculation of the t-test formula with the degree of significance 5 and 1.
Before using t-test formula, the writer has to seek the differences of mean variables by using formula as follows: And after getting the mean variables, the writer has to seek the standard of deviation of variable and standard error mean of
variables by using formula as follows:
∑ ∑

The next step is seeking the standard error mean difference of variables by using formula as follows:

CHAPTER IV RESEARCH FINDINGS
This chapter presents and discusses findings of the research based on data gathered during the investigation. In line with the research findings, it discusses: 1 description of data, 2 the analysis of
data, and 4 the interpretation of data.
A. RESEARCH FINDINGS
1. Description of Data
To know the result of the experiment, the writer calculate the result of post-test of both classes, where variable X is the post-test result of the experiment class through teaching English using
visual media and variable Y is the post-test of the controlled class through teaching English without using visual media.
