CHAPTER IV DATA ANALYSIS AND DISCUSSION
This chapter discusses the results of the study based on data analysis and the discussion of the research findings.
4.1 Activities of Experiment
In this research, there were four main activities. These were the activities of constructing instrument, pre-test, treatments, and also post-test. These activities
were done in different time.
4.1.1 Constructing instrument
Before the test was used to gain the data of evaluation, there were some stages that should be done in constructing the instrument in order to get good instrument.
The stages as follows: a Limitation of Material learning
The material of learning that will be tested in this research was limited only in simple past tense especially regular and irregular verbs.
b Constructing Lattice Work The lattice work of the instrument could be seen on Appendix 8.
c Test Time Allocation The tryout test instrument used in this study was non-standardized in the form
of multiple choices. The time allocation needed to finish the tryout was 90 minutes with the number of the test items were 50 items.

4.1.2 Try out
Before the instrument given to the experiment group and the control group as a measurement students‟ achievement, it was firstly done the try-out tes
t to
know whether the test goo to be tested or not
.
The try-out test consisted of Pre-Test and Post-test. The try-out was conducted on March 2
nd
, 2011. The try-out test of Pre- test was done to XI IPS 3, and the try-out of post-test was done to XI IPS 1 of
SMA N 1 Subah in the academic year 20102011. The complete analysis of pre- test and post-test try-out could be seen in appendix 9. The following were the data
interpretation of the try-out test to find out the whether the instrument fulfils the requirement of good or not.
The instrument that will be used in measuring try-out test analysis involves validity, reliability, difficulty level, and discriminating
power.
4.1.3 Pre-test
Pre-test was given before doing the treatment of this experiment research. The pre-
test was given to the students‟ grade eleventh IPS 2 and IPS 4 of SMA N 1 Subah at Friday, March 11th 2011. In IPS 2 which as control group held at 07.00
o‟clock while in IPS 4 which as experiment group held at 10.00 o‟clock. In pre- test, the test was 40 items of simple past tense especially regular and irregular
verbs. The time allocation of the test was 60 minutes. Pre-test was used to know how far the students‟ mastery of simple past tense before the treatments were
given the pre-test can be seen on appendix 10.
