CHAPTER IV RESEARCH FINDINGS AND DISCUSSION
A. Finding
In finding section, the researcher presents finding based on the data collected during the research. The aimed of this study would to find out the significance different between of the students speaking accuracy taught through the use of Quantum Teaching method and those who are taught through the use of Direct method. The explanation can be seen as follows:
1. The results of pretest for experimental group and control group.
a. The results of the students speaking accuracy in pretest for experimental and control.
The pre-test was aimed to discover the equity of the two groups before administering treatments by using t-test procedure. It was conducted on October, 13th 2015 to two classes of the seventh grade students of MTs YASPI Sambung Jawa. The pre-test involved 34 students that divided into two classes. Class VII A was as experimental group and VII B was as control group. Each of group consists of 17 students. In assessing students’ speaking, this study assessed three aspects of speaking namely, pronunciation, vocabulary, and grammar.
The table below would describe the result of students speaking accuracy in pretest for experimental group and control group.

Table. 4.1 the result of students speaking accuracy in pretest for experimental group and control group.
(source: appendix 1.a and 1.b) In pretest, the pronunciation of the students was conducted by using recorder. The result of students’ pronunciation in pretest showed that the mean score students’ pronuciationin experimental group was 4.71. And the mean score in control group was 4.02.
The mean score of the students’s vocabulary in pretest for exprimental group was 4.80. the result of mean score students vocabulary in control group was 4.71.
The result of the students’ grammar in pretest showed that the mean score of the students’ grammar in experimental group was 4.21. The result of mean score students vocabulary in control group was 3.72.
Speaking accuracy Mean score in pretest Experimental group Control group
Pronunciation 4.71 4.02
Vocabulary 4.8 4.71
Grammar 4.21 3.72
b. The mean score students speaking accuracy in pretest for experimental and control group.
The result of mean score students accuracy in pretest was from the total of score students accuracy that have conducted. The mean score result in experimental group was 4.58, and the mean score result of control group was 4.15. The result was described in table below:
Tabel 4.2 the mean score in pretest Mean score
Students Experimental Group Control group
N=17 = 4.58 = 4.15
(source: appendix 1.c) Based on the table above, the mean score of experimental group in pretest was 4.58, and the mean score of control group was 4.15. It means the mean score experimental group was higher than control group before treatment was given.
c. The significant testing of t-tes and t-table in pretest.
Table above show the significance result of t-test and t-table.
table 4.3 the significant result of t-tes and t-table in pretest.
Student Pretest Significance
N= 17 t-test t-table Not significance
1.95 2.042
(source: appendix 1.d)
The result of the calculation of t-test on pre-test (in appendix 1.d) was 1.95. In the t-table (in appendix 3) forα= 0.05 df = 32 t-ratio was 2.042. The data showed from the experimental and control groups were equal with the value of t was lower than t-table (1.95 < 2.042). It indicated that the alternative hypothesis was rejected; there was no significant difference between the data of the two groups. This result implied that the experimental and control group were similar in their initial ability.
2. The results of postest for experimental group and control group.
a. The results of the students speaking accuracy in postest for experimental and control.
The post-test was aimed to discover the equity of the two groups after administering treatments by using t-test procedure. It was conducted on October, 27th 2015 to two classes of the seventh grade students of MTs YASPI Sambung Jawa. The pre-test involved 34 students that divided into two classes. Class VII A was as experimental group and VII B was as control group. Each of group consists of 17 students. In assessing students’ speaking, this study assessed three aspects of speaking namely, pronunciation, vocabulary, and grammar.
The table below would describe the result of students speaking accuracy in pretest for experimental group and control group.
Table. 4.4 the result of students speaking accuracy in postest for experimental group and control group.
(source: appendix 2.a and 2.b) In posttest, the pronunciation of the students was conducted by using recorder. The result of students’ pronunciation in posttest which showed that the mean score students’ pronuciation in experimental was 7.06. The mean score students pronuciation in control group was 4.41.
The result of the students’s pronunciation in posttest which showed that mean score students’vocabulary in exprimental group was 6.28. The mean score students vocabulary in control group was4.8. The result of the students’ grammar in posttest which showed that the mean score of the students’ grammar in experimental group was 5.49. The mean score students grammar in control group was 3.43.
Speaking accuracy Mean score in posttest Experimental group Control group
Pronunciation 7.06 4.41
Vocabulary 6.28 4.8
Grammar 5.49 3.43
b. The mean score in posttest for experimental and control group.
The result of mean score students speaking accuracy in posttest was from the total of score students accuracy that have conducted. The mean score result in experimental group was 5.45, and the mean score result of control group was 4.21. The result was described in table below:
Tabel 4.5 the mean score in postest Mean score
Students Experimental Group Control group
N=17 = 5.45 = 4.21
Based on the table above, the condition of both classes could be seen on the chart below:

Mean Score
The chart above showed that the means of both experimental and control groups were significantly different. Mean of experimental group was higher than mean of control group after conducting treatment.
c. The significant testing of t-tes and t-table in postest.
Table above show the significance result of t-test and t-table.

N= 17 t-test t-table Significance
2.69 2.042
(source: appendix 2.d)
The result of the calculation of t-test on post-test (in appendix 2.d) was 2.69. In the t-table (in appendix 3) for α = 0.05 df =32 t-ratio was 2.042. Based on the calculation, the value of t was higher than the ratio on t table, 2.69 < 2.042. According to the result, it could be concluded that the alternative hypothesis was not rejected. There was a significant difference between students who were assigned Quantum teaching method and students who were not.
3. The significance testing between pretest and posttest who are taught through Quantum Teaching method and who are taugh through Direct Method.
The significance different would be shown with compare the result of t-test and t-table in pretest and post test in experimental and control group by describe table below:
Table 4.7 the significance testing of t-test and t-table
Based on the table above, the value of t-test in pretest was 1.95, it means the value of t-test was lower than t-table, so there was no significance different between two group. But after treatment was given the value of t- test was higher than t-table. So, there was significance difference between two group.
