From the data gained the homogeneity test for post-test was
1.51
. From the result of homogeneity was consulted to
fisher
table, it was found that F
critical
of 0.05 30,30 = 1.84. The data come from homogeneous data provided F
observed
is lower than F
critical
F

F
critical
it means that the variance of the data of post-test in both control class and experimental class is homogenous. see Appendix 21-23
3. Result of Hypothetical Test
The hypotheses are: H
o
= There is no influence of using audio visual media towards students‟
pronunciation mastery of the eighth grade at the second semester of SMPN 01 Rebang Tangkas Way Kanan in academic year of 20152016.
H
a
= There is influence of using audio visual media towards students‟ pronunciation
mastery of the eighth grade at the second semester of SMPN 01 Rebang
Tangkas Way Kanan in academic year of 20152016. The criteria of the test as follows:
H
a
is accepted if t
observed
is higher than t
critical
, or t
observed
t
critical
H
o
is rejected if t
observed
is lower than t
critical
, or t
observed
t
critical
In this case, the writer used the level of significant α = 0.05.
Based on the calculation was obtained t-test is 7.695, and the result of level of significant 0.05 is 1.671see appendix 24-26 and 38. From this it can be seen that the
result of t
test
is t
observed
t
critical
, H
a
is accepted because 7.695 1.671. Then it can be assumed that there is significant
influence of using English movie towards students‟ pronunciation mastery at the second semester at the eighth grade of SMPN 1 Rebang
Tangkas Way Kananin the academic year of 20152016.
D. Discussion
Based on the finding of the research, it was found that the students who were taught by using audio visual media video had increased their pronunciation mastery. It
might be due to in using that media the students were highly involved in understanding a lot of pronunciation mastery.
Audio visual media video is a tool or media and can be a good medium in teaching learning process. Its function as media is not just for learn about pronunciation, but it
can develop English skills, like as listening, speaking, reading and writing. Since the students in experimental class learnt to increase their pronunciation mastery with that
media, they exactly had many vocabularies. They did not feel bored and undress pressured like as the students in control class which learnt with only visual media.
Based on the result of the pre-test before English movie was implemented, the students‟ pronunciation mastery was lower than after English movie was
implemented. After getting the treatments and post-test was conducted, it was found that there was significant difference between the experimental class and the control
class where the post-test score of the experimental class was higher. It could be seen from the mean in pre-test score of control class was 69.6 and in the post-test was
