4.5 Discussion of the Research Findings
The aim of the tests, pre test and post test,were to investigate whether there is any signific
ance difference of the students‟ achievement in writing descriptive text taught by using flashcards in control group and BBC Nature videos in
experimental group as media at the eight year students of SMP Negeri 3 Sawangan, Magelang in the academic year of 20122013.
In the pre-test, the average scores of the control and the experimental groups were 65.07 and 65.47. From the pre-test, it can be said that the ability of
the two groups was relatively the same. From the scores, it can be concluded that the two groups were homogenous, because there was only slight difference in the
pre-test result between the control group and the other one experimental group.After they received the treatment, the average score of the experimental
group was higher than the control group. The experimental group got 84.00 and the control group got 76.67.
Providing students with BBC Nature videos made an upgrading in their writing ability more than giving them flashcards. It can be seen in the average of
each aspect both in the pre-test and the post-test section below.

From both of the tables above, it can be seen that the students writing ability in describing a particular animal based on the flashcards and the BBC
Nature videos was increasing, but the posttest score of the experimental group of each aspects was higher than the score of the control group. The increasing ability
involved the whole aspects of the components of writing: form, grammar, style, content, mechanic, as explained below :
1 Students‟ Form in Writing
Talking about form, the students‟ ability in organizing sentences into a good paragraph was so poor. They still produced simple and rather unorganized
sentences. After being given the treatment by using BBC Nature videos, the
ability of the experimental group in organizing sentences was getting better comparing to the control group after being given treatment by using flashcards.
In the post- test, the students‟ form in writing showed an improvement. The
following table shows the results.

The control group students‟ writing form improved. It can be proved by the pre-test score, 72.67, and the post-test score, 84.67. It meant the students
had made 12points improvement.
Meanwhile, t he experimental group students‟ writing form also improved.

meant the students had made 18.67points of improvement. Therefore, the
experimental group had made higher improvement than the control group. 2
Students‟ Grammar in Writing Moreover, the student‟s ability of both the control and the experimental groups
in comprehending grammar aspect was weak. The students in those groups showed that they had poor ability in producing good structure. The given
treatment influenced their grammar ability and gave contribution to improving their grammar comprehension. The result of the experimental group who was
taught by using BBC Nature videos was higher than the control group. In the post-
test, the students‟ grammar in writing showed an improvement. The following table shows the results.

Many of the students in both experimental and control group were poor in grammar. In the post- test, there was an improvement and the experimental
group got higher score than the control group.The pre-test score of control group was 62 and the post-test was 70.00. It meant the students improved
8 points. The pre test score of the experimental group was 62 and the post test
was 76.67. It meant the students of the experimental group improved14.67 points.
3 Students‟ Style in Writing
The students‟ ability in mastering vocabulary was also poor. They did not use appropriate words in showing their ideas on the written products of their pre-
test. In the post- test, the students‟ style in writing showed an improvement. The
following table shows the results.
