CHAPTER III METHOD OF INVESTIGATION
This chapter presents the description of the methodology used in conducting the research. Which includes: research design, subject of the study, instrument of the
study, the steps of the research, stastical design, method of analyzing data, and method of reporting the result.
3.1. Research Design
In achieving the objective of the study, the writer used experimental research to obtain the required data and information. The approach used is quantitative
method which means the method and instrument involve numerical measurements and the statistical quantification was conducted.
3.1.1. The Experimental Design
Nunan 1992: 25 states that “Experiments are carried out in order to explore the strength of relationships between variables.” From the definition above it can be
said that experimental research is the research which compares two variables or more in order to get the valid conclusion.

3.1.2. Procedure of Experimental Design
This study used “pretest – post test” design. This design can be describe as follows:
E 01
x 02
C 03
y 04
Arikunto, 2002: 79 Where:
E: Experimental group C: Control Group
01: Pre-test for the experimental group 02: Post-test for the experimental group
03: Pre-test for the control group 04: Post-test for the control group
x: Treatment using old and new information y: Treatment using jumbled sentences.
It can be explained that subject were assigned to the experimental group E and the control group C. The quality of the subjects was first checked by pre-
testing them 01 and 03, and the experimental treatments were given. The experimental group was taught news item by using old and new information. On
the other hand, the control group was taught news item by using jumbled sentences. After finishing the treatments, the post-test was given to both
experimental and control group 02 and 04. This post-test was conducted in order
30
to measure the students‟ achievement after getting the treatment. The effectiveness of the treatment was shown by the differences between the control
group‟s score 04 - 03 and experiment group‟s score 02 – 01 were then computed statistically.
3.1.3. Procedure of the Experiment
The procedure of this experiment was as follows: 1
Choosing the grade X students of SMA N 1 Slawi as the population. 2
Taking two groups of the students as the samples, one as the experimental group and the other as the control group.
3 Conducting real experiment and collecting data then the last one is
analyzing data.
