CHAPTER IV.FINDINGS AND DISCUSSION
A. Findings
The research findings indicated that teaching vocabulary by using Mnemonic strategy can improve the students’ vocabulary in the terms of adjective and noun. The further interpretations of the data analysis are given below:
1. The improvement of the students’ vocabulary in the term of adjective The application of Mnemonic Strategy in improving the students’
vocabulary in the term of adjective. It is proved by the vocabulary test as indicated by the significant difference between the score of pre-test and post- test. The improvement of the students’ vocabulary in the term of adjective can be seen clearly in the following table:
Table 4.1. The Students’ Vocabulary in the term of Adjective Pre-test Post-test Improvement
42.27 90.45 53.26%
The use of Mnemonic strategy in developing the students’
vocabulary in the term of adjective. In the pre-test the students got low score (42.27 ) because they were still confusedto understand about the vocabulary and they didn’t understand well about the vocabulary.
The table above showthat the students’ improvement of vocabulary in the term of adjective. Before the implementation of mnemonic strategy
indicated that pre test assessment is very poor (42.27) but after the implementation of mnemonic strategy in post test, the assessment of their vocabulary in the term of adjective improve. The assessment of the students’
vocabulary in the term of adjective is 90.45. It was classified as very good which means that there is an improvement of the students’ vocabulary in termof adjective. Therefore, the improvement of the students’ vocabulary in the term of adjective from pre-test to post-test is (53.26%).
Based on the percentages above there is a significant improvement of students’ vocabulary in the term of adjective after taking an action after pre- test by using Mnemonic Strategy.

The graphic above indicates that the mean score of pre test is 42.27.It means that the students’ has the score classified as poor. This also means that the target in pre-test has not been achieved yet. Therefore the researcher decided to

continues treatment by using mnemonic strategy. In the post-test, the students’
mean score is 90.45. It means that the students’ has the score classified as very good and gained improvement, so it can said that there is a significant improvement of the students’ vocabulary especially for adjective that shown clearly in the chart after taking an action in treatment by using Mnemonic Strategy.

Based on the table above shows that in the cycle 1 there were no
students got excellent,very good, good, and fairly good score. There were 6students (27.27%) got fair score,8 students (36.36%) got poor, and there were 7 students got very poor score. After implementation of Mnemonic Strategy, In the post-test there were no students gotvery poor, poor, and fair. But there were9 student(40.90%) got excellent score, there were7 student got very good score ( 31.81%), there were 4 students (18.18%) got good score, only 2 student (9.09%) got fairly good score.
2. The improvement of the students’ vocabulary in the term of noun
The application of Mnemonic Strategy in improving the students’
vocabulary in the term of noun. It is proved by the vocabulary test as indicated by the significant difference between the score of pre-test and post- test. The improvement of the students’ vocabulary in the term of noun can be seen clearly in the following table:
Table 4.3. The Students’ Vocabulary in Noun
Pre-test Post-test Improvement
47.72 87.72 45.59%
The use of Mnemonic strategy in developing the students’
vocabulary in the term of noun. In the pre-test the students got low score (47.27 ) because they were still confusedto understand about the vocabulary and they didn’t understand well about the vocabulary.
The table above showthat the students’ improvement of vocabulary in the term of noun. Before the implementation of mnemonic strategy indicated that pre test assessment is very poor (47.72) but after the implementation of mnemonic strategy in post test, the assessment of their vocabulary in the term of noun improve. The assessment of the students’ vocabulary in the term of noun is 87.72. It was classified as good which means that there is an improvement of the students’ vocabulary in term of noun. Therefore, the improvement of the students’ vocabulary in the term of noun from pre-test to post-test is 45.59%.
Based on the percentages above there is a significant improvement of students’ vocabulary in the term of noun after taking an action after pre-test by using Mnemonic Strategy.

The graphic above indicates that the mean score of pre test is 47.72It means that the students’ has the score classified as poor. This also means that the target in pre-test has not been achieved yet. Therefore the researcher decided to continues treatment by using mnemonic strategy. In the post-test, the students’
mean score is 87.72. It means that the students’ has the score classified as very good and gained improvement.

Based on the table above shows that in the pre-test 1 there were 2
students got excellent score (9.09%), There was1student (4.54%) got very good score,4 students (18.18%) got good, there were 3 students got fairly good score (13.63%), There were2 student (9.09%) got fair score, there were2 students (9.09%) got poor score, and there were 8 students got very poor score(36.36%).After implementation of Mnemonic Strategy, In the post-test there were no students got very poor, poor, and fair. But there were 6 student(27.27%) got excellent score, there were 10students got very good score ( 45.45%), only 1 student (4.54%) got good score, and there were 5 student (22.72%) got fairly good score.
3. The significant of adjective and noun
The researcher was used t-test analysis on the level of the significance (p)= 0,05 with the degree of freedom (df)= N-1, where N = number of subject ( 22 students ) then the value of t-table is 2.080. the t-test statistical, analysis for independent sample was applied. The following table shows the result of t-test calculation :
Table 4.5The t-test of the Students’ Improvement
No Components T-test value T-table value
1. Adjective 2.67 2.080
2. Noun 1.65 2.080
The table 4.3 above shows that t-test value for adjective was greater than t- table (2.67> 2.080), t-test value of noun wassmaller than t-table (1.65<2.080). It means that there was significant difference between the students’ vocabulary before and after using Mnemonic Strategy in vocabulary at the eight grade students of SMP Negeri 33 Bulukumba. It is also said that the null hypothesis ( H0
) was rejected and the alternative hypothesis (H1) was accepted.
