Then the teacher asked the students to read those examples. After that the teacher explained and gave the pattern or rules of comparative and
superlative degree. After that, the teacher asked the students to make other examples and some exercises of comparative and superlative degree.
B. Research Findings
1. Data Description
To know the result o the test, the writer makes the table of students’ score for each follow:
M
pre-test
= X
o
=
2340 = 57.07 N 41
M
post test
= X
1
=
3145 = 76.70 N 41

o
=
2220 = 54.14 N 41
M
post test
= X
2
=
2895 = 70.60 N 41
After making the table of the test score of the experiment class and controlled class, the writer calculated the frequency of the score by using
the following steps:

3. The Test of Hypothesis
The writer states the hypothesis as follow: 1.
Alternative hypothesis H
a
=There is significant difference between students’ achievement in learning degrees of comparison
using visual media and without using visual media. 2.
Null hypothesis H
o
= There is no significant difference between students’ achievement in learning degrees of comparison using
visual media and without using visual media. According to Sudijono if the result of calculation t
o
t observation is higher than t
t
t table, t
o
t
t
; the null hypothesis Ha is rejected. It means that there are significant differences
between students’ achievement in learning degrees of comparison using visual media and without using visual media. If the result of
calculation t
o
t observation is lower than t
t
t table, t
o
t
t
; the null hypothesis H
o
is accepted.

media. Based on the calculation indicates that the value of t
o
is is 2.577 and the value of df 80 on degree of significance of 5 is
1.99. Comparing the t
o
with value of degree of significance, the result is t
o
t
t
2.577 1.99. Since t
o
which is obtained from the result of calculation is
higher than tt, so the alternative hypothesis H
a
is accepted and the null hypothesis is rejected. It means there are significant differences
between students’ achievement in learning degrees of comparison using visual media and without visual media. So, using visual media
is more effective and applicable in teaching degrees of comparison at Second Year of SMP PGRI I Ciputat.
