as a sample because at that time there are some students was sick. That was taken from the class of VIII-G and VIII-H, the VIII-G which is
employed 17 students as the control class and VIII-H which is employed 16 students as the experiment class. The sample is taken by using saturated
sampling.
5. Technique of Data Collecting
The technique of collecting data used in this research is: Test, the writer gave the students two test namely pre-test and post-test. Pre-test was given
before she began the teaching learning process in two classes. And the total numbers of the test are 20, which is the pre-test is similar in form to
post-test that was given after two times of the instruction.
6. Technique of Data Analyzing
To find out the differences of students’ score in using the difference of students score in using Audio-Lingual Method and Grammar Translation
Method in teaching the Present Continuous Tense the writer used pre – test
and post – test. After getting the data from the observation, pre – test and
post – test, they are analyzed and processed by the formula of t-test which
was used in this research with the significance degree 5
1
. The formula is:
t = Means that:
: Mean of the Difference of Experiment Class
: Mean of the Difference of Control Class : Standard Error of Experiment Class

d. Determining Standard Deviation score of Variable Y, with formula:
= e. Determining Standard Error of Mean of Variable X, with formula:
= f. Determining Standard Error of Mean of Variable Y, wit formula:
= g. Determining Standard Error of Difference of Mean of Variable X and
Variable Y, with formula:

freedom df: Df = N1 + N2 – 2
Variable X : Experiment Class Teaching the Present
Continuous Tense through ALM Variable Y
: Controlled Class Teaching the Present Continuous Tense through GTM
j. The Hypotheses The statistic hypothesis stated:
Null Hypothesis Ho: There is no effectiveness between teaching the present continuous tense through Audio-Lingual Method ALM and
Grammar Translation Method GTM for the second grade at Al-Binaa of Islamic Boarding School Bekasi.
Alternative Hypothesis Ha: there is effectiveness between teaching the present continuous tense through Audio-Lingual Method ALM and
Grammar Translation Method GTM for the second grade at Al-Binaa of Islamic Boarding School Bekasi.
