2. Post-test The post-test is given to know the
students’ understanding of the material about the parts of face vocabulary after the writer gives the
explanation using picture and translation method. Is there any significance different between picture and translation method. The writer gives the
same questions for pre-test and post-test. The writer made 20 items divided by two categories: 10 multiple choices the score is 1 for each
item. 5 fill in the blanks the score is 2 for each item. 5 complete these sentences the score is 3 for each items.
To get the final score is 35 x 10 = 100. 3.5
6. The Research Instrument
The technique of data is carried out for getting the objective data of students’ achievement in teaching vocabulary using picture and teaching
vocabulary using translation method. The writer applies two tests namely pre-test and post-test, both of the results used as a data.
There are 20 items divided by two categories: 10 multiple choices the score is 1 for each item. 5 fill in the blanks the score is 2 for each item.
5 complete these sentences the score is 3 for each items. To get the final score is 35 x 10 = 100.
3.5 So if the students can answer all of the questions correctly they will
get 100 score.
7. The Research Variable
In this research, the writer used two variables. Those are independent variable and dependent variable. Independent variable is used
in this research is pictures, whereas dependent variable is teaching vocabulary.
8. The Techniques of Data Analysis
To find out the differences of students score in using picture and translation method in teaching vocabulary the writer used pre-test and
post-test. After getting the data from pre-test and post-test, they are analyzed and processed by using statistic calculation of the t-test formula
with the significance degree 5. The formula is:
t
o
= __
M1 – M2_________
{ ∑x1
2
+ ∑x2
2
{ N1 + N2 }
N1 + N2 − 2 N1 x N2
The procedure of calculation as formula: a. Determining mean Variable X1 with formula:
M1 = ∑X1
N1 b. Determining mean Variable X2 with formula:
M2 = ∑X2
N c. Determining deviations Variable X
1
with formula: X
1
= X1 – M1
d. Determining deviations Variable X
2
with formula: X
2
= X2 – M2
e. Determaining t
o
with the formula : t
o
= __
M1 – M2_________
{ ∑x1
2
+ ∑x2
2
{ N1 + N2 }
N1 + N2 − 2 N1 x N2
f. Determaining t-table in significance level 5 with df: dƒ = N1 + N2 – 2
Where: M1
: Mean of Post-test of the experimental class M2
: Mean of Post-test of control class ∑X
1 2
: Sum of square deviation score in the experiment class ∑X
2 2
: Sum of square deviation score in the control class N1
: Number of students of the experimental class N2
: Number of students of the control class d
� : Degree of Freedom d
� : N1 + N2 − 2
B. THE FINDING OF THE RESEARCH
1. The Data Description
To know the results of the students pre-test and post-test, the writer makes the table of the students score from both classes experiment class
and control class. The test result of the experimental class are tabulated and calculated in the
following table:
