: The s tudents’ achievement in writing recount text, who are taught without
using photograph.
The assumption of the hypothesis as follows: 1. If t-test t-table in significant level of 5 and 1, the null hypothesis is
rejected and the alternative hypothesis is accepted. It means that there is significant differen
ce between the students’ score in learning writing recount text by using photograph and the students’ score in learning writing recount
text without using photograph at the eight year students of SMP Nusantara Plus Ciputat

. The use of photograph is effective towards students’
skill in writing recount text. 2. If t-test t-table in significant level of 5 and 1, the null hypothesis is
accepted and the alternative hypothesis is rejected. It means that there is no significant difference
between the students’ score in learning writing recount text by using photograph and the students’ score in learning writing recount
text without using photograph at the eight year students of SMP Nusantara Plus Ciputat

CHAPTER IV RESEARCH FINDING AND INTERPRETATION
A. Research Finding
1. Data Description
Before doing the calculation by using t- test, the data of the students’ pre-test
and post-test score of experimental and control class that had been collected is described as follows:

Based on the table above, it can be seen that the score of the students’ pre-test
and post-test in the experimental class are different . The mean of the students’
score in pre-test is 53.97 with the lowest score is 39 and the highest score is 71. Meanwhile the mean of the students’ score in post-test is 75.64 with the lowest
score is 49 and the highest score is 97.

Based on the table above, it can be seen that the score of the students’ pre-test
and post-test in the control class are different. The mean of the st udents’ score in
pre-test is 51.35 with the lowest score is 34 and the highest score is 75. Meanwhile the mean of the stu
dents’ score in post-test is 57.11 with the lowest score is 34 and the highest score is 73.
According to the data in the tables above, it shows that the students’
achievement in writing recount text by using photograph in experiment class is higher than the students’ in control class without using photograph. It is also
described by the figure of chart as belows:
