Data analysis shows that t

Procedure of Collecting Data The procedures were as follows:

1. 
   Pre-Treatment
   

Before giving treatment by using audio visual as media in teaching and learning, the researchers give pre-test. On the result of pre-test, the researchers found that the fourth grade students’ result pre-test was poor. The reason is because the teacher never tries to teach vocabulary by using audio visual media such as cartoon film. The English teachers in MI Al Hidayah 02 Betak teaches the students only use students’ worksheet withouth color and it makes the students difficult to memorize about vocabulary like animals, food, beach, and color.

2. 
   Treatment
   

The treatment in this research is audio visual media especially cartoon film, the researchers taught vocabulary by using audio visual as a media of teaching. The material animals, clothes, and beach are used to teach vocabulary, in order to increase their vocabulary mastery. Audio visual media help the students easier to memorize vocabulary. The students can see and hear by using audio visual media especially video disc (film) with instruction for teacher. It makes the students were enthusiasm, enjoyable and interested in learning English. When teaching and learning process were conducted by using audio visual media especially (cartoon film) is done, the students were very happy and they got new spirit to learn English.

3. 
   Post Treatment
   

After doing treatment, it is given posttest to all students. Posttest is used to know the students vocabulary mastery after teaching by using audio visual media especially cartoon film; how far the students understand and remember about some vocabulary that given after giving treatment process is done. Apparently, the result of the test showed that the students’ vocabulary mastery improved significantly, because their scores after giving treatment is higher than before.The last, after the class has been exposed to the treatment for some period of time, the administering test of the dependent variable (or otherwise measures it). After reducing, classifying, analyzing the data, and then determining whether there is/are any significant different between before using cartoon film and after using cartoon film as media, it is determined whether the treatment made the different or not.
The instruments used by the researchers are as follows:

1. 
   Pre-Test
   

Before teaching the new material by using cartoon film media as media or without using it, a test is given to the students by taking the previously material. A test is a means of measuring a knowledge skill, feeling, intelligence of an individual of group. Test produced numerical score that can be used to identify, classify, or evaluate test takers. There are two tests, pre-test and post-test. Pretest was given to the experimental group and control group by conducting some tests, in other word, it is used to know the ability to the students. The score obtained were analyzed to determine between pre-test and post-test. The respondents were asked to do the twenty five questions of vocabulary. Time allocation of test is 60 minutes. This kinds of test is ten multiple choices, ten questions to arrange the sentence in good order, five items as matching the picture.

2. 
   Treatments The treatments here mean instruction media refers to cartoon film “Dora’s film” and related materials that served instructional function for education treating. Treatment of cartoon film “Dora’s film” also uses the power of teacher, word, and sound to complete attention, to help an audience understand ideas and acquire information to complex for verbal explanation, alone and to help overcame. The limitation of time, size, and space, the researchers conducted treatment in classroom. The treatment, which is used here, is using audio visual media especially cartoon film “Dora’s film”. This study uses a LCD Projector to show the picture and use an active speaker to make sound louder. The class was treated pre-test, treatment by using audio visual especially cartoon film “Dora’s film” as media to teach vocabulary, and post-test.
   
3. 
   Post Test
   

To get the data, a post test was given to the post test group because the design of this study is one group pre test and post test. It was given in order to know the scores of the students after they were taught by using audio visual especially cartoon film “Dora’s film” as media. The respondents were asked to do the twenty five question of vocabulary. Time allocation of test is 60 minutes. This kinds of test is ten multiple choices, ten matching pictures, five coloring the pictures. In order to get the valid data, the researchers conducted: 1) Face validity: a try out was valid in term of face validity because with superficial inspection of the test format. This test was an English test for the fourth grade in MI Al Hidayah 02 Betak. The validity of test is important, a test has good validity if most of the testee will be motivated to try harder and do the test as the result the test seems to be effective; 2) Content validity is a kind of validity which depends on careful analysis of the language being tested and particular test. Trying out test of this study had content validity because the items taken were from the fourth grade students.3) Reliability: reliability is a necessary characteristic of any good test for it to be valid at all and a test must be reliable as measuring instruments. A test was given for 25 students to know the reliability of test. The reliable of whole test can be estimated by using formula (Sumarna,

Where:
r₁₁ = Reliability using equality KR-20
p= proportion of correct answer for an item q= proportion of incorrect answer for an item (q=1-p)
∑pq = total multiplication between p and q
k= total of question S = standart deviation
N = amount of the students
∑x² = Number of Deviation Square
The result of Reliability can be seen in Appedix IV
In experimental design, the technique analysis data that is experimental group and control group pre test post test design. It means that it has two variables investigated in this research are cartoon film media and vocabulary mastery two know there are different before and after being taught by using cartoon film media. The collected data is analyzed by using quantitative data analysis.
Quantitative data analyzing is also called statistical analysis. Usually the data classified into numerical form. In the experimental research by using pre test and post test one group designs, the data are analyzed by using the following formulation of t-test (Arikunto, 2006:86)
Md
t =

N(N  I)

Notes :
Md	= means of differential pre test and post test
Xd	= deviation in every subject (d-Md)
x^2d	= Total of quadrate deviation
N	= Subject of sample
d.b	= Decided by N-1

The formula above is used to count the effectiveness of treatment.
