Based on the output of Independent sample T-test by using SPSS, the degree of freedom df of post test was 42,948. T
he value of Lavene’s Test of Equality variances is 0.000 or we can say that it is less than 0,05. If the value of
Sig. 2 tailed is less than 0,05, it indicated that the null hypothesis H was
rejected. That is why the alternative hypothesis H
a
with 95 confidence interval of the difference was accepted.
4.4 Discussion
The result of data analysis reported that using picture series as media in teaching learning process gave significant effect on writing achievement of the
eleventh grade students of MAN 2 Jember in the 20142015 academic year. It was proved by the results of the output of Independent sample T-test by using SPSS on
previous section, the significant column value of t-test was 0.000 and it was less than 0.05. It indicated that the result of t-test analysis was significant. From table
scores of post test, it can be seen that the experimental group who was taught writing by using picture series as media in teaching learning process got better
score compared to the control group who was taught writingwithout using picture series.
The observation result that was conducted by the researcher in the teaching learning process during the research supported the result of data analysis of
Independent sample T-test by using SPSS. Based on the observation result, the students in the experimental group were more active than the students in the
control class. It happened because the students in the experimental group were so interested in writing a narrative text using picture series. It helped them memorize
the plot of the story easily. Besides, the teaching learning process in the experimental group was more conducive than the teaching learning process in the
control group. It happened because in the experimental group the students could study writing by using attractive and colorfull picture series. It was a fun activity.
That situation helped the students learn writing a narrative text well. The result of this research is in line with Yunus 1981:53 who also states
that pictures can provide stimulus for using language in productive skills; that is
speaking and writing. Based on Yunus’ idea, one of the reasons why the use of
picture series in teaching learning process is effective is because pictures is provide stimulus to the studets to memorize the plot of the story.
The result of this research is also in line with Erlys 2012 who reported that picture series
could improve the students’ reading achievement. In other words, the result of this research supported Wibowo
’s research. Besides, the result of this research is also in line with the previous research conducted by Mirza
2013 who stated that there was a significant effect of using picture series on the eleventh grade students’ speaking achievement in story telling at SMAN Arjasa in
the 20122013 academic year. It could also be said that the results of Erlys research, Wibowo
’s research and Mirza’s research supported the result of this research in using picture series as media.
From the explanation above, it could be said that using picture series could help the students to improve their writing achivement. In conclusion, based on the
result of this research and the discussion above, picture series as media in teaching writing gave a significant effect on writing achievement of the eleventh grade
students at MAN 2 Jember in the 20142015 academic year.
