Table 4.3 showed the result of the study of the thirty-two students of XII IPS 4. We could see from the table that students‟ speaking achievement in the pre-test
was 6.61, whereas the students‟ speaking achievement in the post-test was 12.20. It means that there was an improvement between mean of pre-test and the post-test. The
improvement score was 5.59. It was taken from the post- test‟s score which was
reduced by the pre- test‟s score. From this calculation, I could conclude that the
increasing score was almost 100. This calculation was also strengthened by the result of the questionnaire given after the post-test in the last cycle.
4.5.3.1 Pronunciation
In this aspect, we can see that the students‟ achievement is increased. It can be seen from the av
erage score of the students‟ pronunciation achievement. The mean score for pre-test is 1.21 and for the post-
test is 2.78. The students‟ pronunciation improved because they have known how to pronounce the words correctly since their
wrong pronunciation were corrected in the first and second cycle.
4.5.3.2 Vocabulary
From the table above, we can conclude that the students‟ vocabulary achievement is improved because they got new vocabularies from the treatment and
the teacher‟s explanation. The mean difference of pre-test and post-test is 1.15. 4.5.3.3 Structure
The students structure achievement is improved. The average score of pre- test is 1.84 and the post-test is 3.06. After the students have treatments, they can use
the appropriate tenses.
4.5.3.4 Fluency
Accor ding to the table above, the students‟ fluency is also increased. The
mean score of the pre-test is 1.28 and the post-test is 2.93. It is influenced by their habit in speaking when they were discussing and reporting their group discussion
result during treatments. Since they had a lot of practice, their fluency achievement in the post-test was increasing than in the pre-
test. It is a good advance in students‟ speaking.
The results of the tests were supported by the diagram below. It was the pre- test and the post-
test‟s scores based on the Clark four-scale scoring system:
Figure 4.1 Chart Diagram of Pre-Test and Post-Test Score The chart diagram above shows us about students‟ pretest-posttest score. The
blue diagram shows the result of pretest while the red diagram shows the result of posttest. Numbers above the pretest-
posttest score are the students‟ number. From the blue diagram, we can see that the lowest score of pretest is 4 whereas the highest one
is 10. While from the red diagram, it can be seen that the lowest score of posttest is 9 whereas the highest one is 14.
