FINDING AND DISCUSSION

The finding shows the students score before they were taught by using cartoon film, the students’ score after they were taught by using cartoon film and the statistical test result as follows.
The result of the test about the students’ achievement before and after using audio visual media especially cartoon film and percentage score in pre-test and post-test will be presented as follows:

The number of the item test given were 25 questions, 10 multiple choices and 10 items arrange the sentences into good order and 5 items as matching the picture for 25 students. The pre-test had been done before treatment process (teaching vocabulary by using audio visual media cartoon film). This test is given to know the basic competence for all students and to know their earlier knowledge before they get treatment. The table shows the mean of pre-test by dividing all of score in pre-test with students number of class. So, the average of pre-test score is X_^X _ ¹⁸⁷⁹ _ 75.16

The number of the item test given were 25 questions, 10 multiple choices, 10 matching the picture and 5 coloring the picture for 25 students. The post-test had been done after treatment process (teaching vocabulary by using audio visual media cartoon film). These tests are given to know the students’ competence after they were taught by using audio visual media cartoon film, and to know their earlier knowledge after they get treatment. The table shows the mean of post-test by dividing all of scores in post-test with the students’ number of class. So, the average of post-test score is :

Statistical Test Result

It is conducted statistical test using t-test formula to guarantee the effectiveness of audio visual media on students’ vocabulary achievement of MI Al Hidayah 02 Betak. The test results are as follows:

After get the result of t _count, so t _count is consulted to t _table d.b = N – 1 = 25 – 1 = 24
it is found t _table for t _0,05 = 1,71
The result of the-test was 5,20. It was consulted the critical value on the ttable using the 5% (0,05) alpha level of significance and the 24 degree of freedom which was 1,71. Since the obtained t-value was higher than the critical value on the table (5,20 > 1,71), the difference was statistically significant. Seeing the result of the pre test &post test, so the null hypothesis is rejected. It means that there were any significant different between score of pretest and posttest.
