4. Test
This study uses pre-test and post-test for collecting the data. The pre-test is conducted before the implementation of transformation drill in teaching verb I in
simple present and verb II in simple past forms. Meanwhile, the post-test will be conduct after the implementation of each cycle. Because of in this research the
CAR consists of 2 cycles so the post-test already deliver in the final action of each cycle. Furthermore, the tests are done in form of multiple choices and fill in
the blank type.
L. The Technique of Data Analysis
In data analysis, the data is derived from observation and interviews will be conducted by researcher to make her easier in reporting the research report. Then
those data will be used to answer the second research question. Meanwhile, to answer the first research question the writer will be analyzed
the data from the test and questioner. After knowing the student’s individual score the writer will be analyzed the average of students’ score per action within one cycle, the
writer uses the formula:
36
=
Σ
: mean x : individual score
n : number of students Then, to get the class percentage which passes the KKM 60, the writer uses
the formula:
37
P =
F N
X 100

P : the class percentage
F : total percentage score
N : number of students
The last, to get the improvement score from the pre-test up to post-test score in cycle 1 and cycle 2, it uses the formula:
38
P = 100
P : percentage of students’ improvement
y1 : post-test 1 result
y : pre-test result
P = 2
−
100
P : percentage of students’ improvement
y2 : post-test 2
y : pre-test result
M. The Trustworthiness of Study
In trustworthiness, the researcher will discuss about data collection in every observation from performing action research cycles are analyzed descriptively by
using percentage to see tendency that happened in learning activity. In analyzed the test item, the writer uses two ways to know the trustworthiness
of the data as follow:
