B. Purpose of Research
This research is aimed to: a.
Find out whether learning the present perfect trough games is effective or not.
b. Know the difference
of the students’ achievement results in using games and without games in teaching and learning the present
perfect tense.
C. Place and Time of Research
The study was carried out at Madrasah ‘Aliyah Islamic Senior
High School Jam’iyyah Islamiyyah Pondok Aren South - Tangerang
which is located on Jl Pesantren, Jurang Mangu Timur Pondok Aren, Tangerang. The writer conducted the research about five weeks. It was
begun by observation and finished by giving the test of understanding the present perfect through games. From March, 11th 2013 up to April, 13th
2013, the writer did the research for six meetings. It consists of giving pre- test, presenting lesson and giving post-test.
D. Population and Sample
The population of the study is 50 students from the tenth year students of Madrasah
‘Aliyah Islamic Senior High School Jam’iyyah Islamiyyah Pondok Aren South - Tangerang which consists of 6 classes.
The writer only took two classes that are X-A and X-B and taught these two classes the present perfect tense using games for experimental class
and without games for control class. The writer took 50 students where 25 students are from experimental class using games and the rest are
control class without games. The sample was taken by using purposive cluster sampling technique because this sampling technique is economy
and feasibility cost efficiency.
E. Technique of Data Collecting
The test was used to collect data. The pre-test and post-test were administered to experimental and control classes. The pre-test was done
before the teaching learning process and the post-test was done after teaching learning process. The pre-test was done in order to know the
homogeneity of two classes and student’s knowledge of the present perfect tense. While, the post-test was done in order to know the influence and the
effectiveness of using games in teaching the present perfect tense.
F. Technique of Data Analysis
Data analysis is the last step in the procedure of research. In analyzing the data of the pre-test and post-test, the writer used the statistical calculation
of T-test. T-test is used in order to find out the differences of the result or score of
student’s achievement in teaching the present perfect through games and without games.
After getting the data, they are preceded and analyzed through the following:
a. Seeking gained score from student’s test of the present perfect items
and describing it in the table. The gained scores of experimental class are variable I that symbolized by X and the gained scores of control
class are variable II that symbolized by Y b.
Determining mean of variable of experimental class with formula MX=
∑X N
c. Determining mean of variable of control class with formula
MY= ∑Y
N d.
Determining Standard of Deviation Score of Variable X SD1, with formula:

e. Determining Standard of Deviation Score of Variable Y SD2, with
formula: =

f. Determining Standard Error of Mean of Variable X, with formula:
SEM
1 =
√
g. Determining Standard Error of Mean of Variable Y, with formula:

h. Determining Standard Error of Difference of Mean of Variable X and
Variable Y, with formula: SE
M1-M2
