Table 4.3 indicates that the value of the t-test was higher than the value of the t-table. It indicates that there was a significant difference between the result of the students’ pre-test and post-test.
To find out the degree of freedom (df), the researcher used the following formula:
Df = N-1 (N = Number of students)
Df = 20–1
Df = 19
For the level of significance (p) 0.05 and df 19, the value of the t- test 6.67 was higher than t-table 2.093 . It means that H0 was rejected and H1 was accepted. So the researcher concludes there was a significant difference between the result of the students’ pre-test and post-test achievement after giving Improvisation techique.
The statistical analysis from the result of the students’ skills in speaking of this research shows that the students’ mastery before teaching through Improvisation techique was still low.
1. The improvement of the students speaking skills in term of pronunciation

It means that the treatment was given to the students in the class was successful in improving the students speaking skills. The improvement of the students scores in term of pronunciation is (32.13%).
The data described the most of them success to improve their score into speakingpronunciation by using Improvisation techique. This improvement is also followed by the significance. The t-test value (6.67) is greater than t-table (2.093) for the degree of freedom (0.05). It means that the null hypothesis (Ho) was rejected and alternative Hypothesis (H1) was
accepted. Based on the data are shown above, it can be concluded that the students speaking score in term of pronunciation of the second grade of SMA Muhammadiyah disamakan Makassar.
2. The improvement of the students speaking skills in term of vocabulary
In improving the students speaking skills the researcher used Improvisation techique and the percentage improvement of the students’

There were 14 students (70%) got very poor score, 6 students (30%) got average score. In post test there were 5 students (25%) got very poor score, 14 students (70%) got average score, 1 students (5%) got good score . It means that the treatment was given to the students in the class was successful in improving the students speaking skills. The improvement of the students scores in term of vocabulary is (18.79%).
The data described the most of them success to improve their score into speaking in vocabulary by using Improvisation techique. This improvement is also followed by the significance. The t-test value (6.67) is greater than t-table (2.093) for the degree of freedom (0.05). It means that the null hypothesis (Ho) was rejected and alternative Hypothesis (H1) was accepted. Based on the data are shown above, it can be concluded that the
students speaking score in term of vocabulary of the second grade of SMA Muhammadiyah disamakan Makassar.
The result of treatment of students activeness in teaching and learning process toward the implementation of Improvisation techique to enhance speaking skill dealing with pronunciation, and vocabulary at the eleventh grade students of SMA Muhammadiyah disamakan Makassar which is conducted with pre test, treatment and post test during 8 meetings.
3. The significantstudent’s speaking skills in term of pronunciation and vocabulary
Through the result of pre-test and post-test, the result of t-test value of the level of the significant 5 % = 0.05, degree of the freedom (df) = 19 indicated that t-table value was 2.093 and t-test value was 6.67.
Therefore, it can be concluded that statistically hypothesis of HI was accepted and the statistically hypothesis of HOwas rejected. It means that the using of Improvisation techique in teaching speaking skill can enhance the students’speaking skill.
