experimental class using the communicative approach and controlled class using audio- lingual method.
The research was done for ten meetings. The writer gave the pre-test in the first meeting. Then, after ten meetings the writer gave post test to both of the class. The test was
same in quality and quantity to keep the reliability of the test. It was given to know which class got better learning achievement.
E. Instrument of Research
The instrument of the research, the writer used the English grammar test to know students’ score in learning the simple present tense. And to know ‘is effective using
communicative approach in teaching the simple present tense?’ The test had been given twice, those are pre-test and post-test. The test consists of 30 questions. In instrument of
research include the specification as follow:

F. Research Procedure
Before doing research, the writer observed the location and population of SMP Islam Al-Fajar. The research was done in two classes, namely in experiment class and control class.
The next step was treatment, where the experiment class would be taught using communicative approach and the control class would be taught using Audio-lingual method.
The writer gave the English grammar test before and after ten meetings in teaching the simple present tense of two classes using communicative approach and another using
audio-lingual method. The test consists of 30 items. There is no different question or format of question that was given to the students.
G. The Technique of Data Analysis
To analyze the data, the writer uses t-test. The writer compared the score between experimental class and controlled class. This technique is useful to prove statistically is more
effective using communicative approach than using audio-lingual method. To find out the differences of students’ score in using communicative approach
compared to the students’ score that used audio-lingual method, so the writer uses t-test formula.
Before using t-test formula, the writer has to find out the mean differences of variables by using formula as follows:
M
1
= M
’
+ i
N fx
and M
2
= M
’
+ i
N fy
And after getting mean differences of variables, the writer has to find out the standard of deviation of variable and standard error mean of variable by using formula as follows:
1. SD

= i
N fx

The next step is found out the standard error mean difference of variables by using formula as follows:

Then the last step is determining t-test by using formula:
