Inductive instruction is an instruction in which the teachers give the examples at the first presentation and guide their student to identify the rule
in example of sentence that their teacher gave, or students can identify the rule by themselves.
Based on the explanation above, it was believed that using inductive instruction in teaching simple present tense can give the stude
nts’ improvement. Therefore, it would be conducted a study of using inductive
instruction in teaching simple present tense. F.

CHAPTER III RESEARCH METHODOLGY
A. Place and Time of the Research
This study was conducted at SMP Islam Bait Al-Rahman that is located on Jl. Duren Tiga Selatan VII, Pancoran Jakarta-Selatan. The time
of this research was from February 2013 up to April 2014.
B. Method and Research Design
The method of the research is a quantitative research. The design of the research is a quasi-experimental research to take two classes in
conducting the research; control class and experimental class. The control class was taught simple present tense using deductive instruction and the
experimental class was taught simple present tense by giving treatment of inductive instruction.
C. Population and Sample
The population of this research was the seventh grade students of SMP Islam Bait Al-Rahman. The sample of the research was taken
purposively by giving simple present tense test to get two classes who have the equal ability.

Based on the tes t’s result, it was chosen VII-A as
the control class and VII-C as the experimental class.
D. Technique of Data Collection
The data of this research was collected by giving tests. The tests were pre-test and post-test. But, it was conducted validity test in MTs. N.
23 Jakarta before giving test to the seventh grade students of SMP Islam Bait Al-Rahman. It was used Anates Software in analyzing the questions in
validity test that can be used in pretest. After that, pre-test was conducted in the first meeting at the two classes in which the purpose is to decide

control class and experimental class. Next, the two classes were given the different treatment
– control class was taught simple present tense by deductive instruction and experimental class by inductive instruction
– in four meetings. Then, post-test was given at the last meeting at control class
and experimental class.
E. Techniques of Data Analysis
The data of this research were analyzed by using t-test formula which is adapted by SuharsimiArikunto, as follows:

=
∑
=mean of gained score of control class ∑ = gained score of control class
= number of students of control class
=
∑
=mean of gained score of experimental class ∑ = gained score of experimental class
= number of students of experimental class
∑ =
∑ –
∑
∑ = deviation of control class
∑ = squared of control class’ gained score
∑ = gained score of control class = number of students of control class
