B. Research Method
The method applied in this research was an experimental method. Experimental research is a research in which the researcher manipulates the
independent variable, as stated by Johnson and Christensen 2000: 23, the purpose of experimental research is to determine cause-and-effect relationships.
The experimental research method enables us to identify causal relationships because it allows us to observe, under controlled conditions, the effect of
systematically hanging one or more variables. In line with the above elaboration, Nazir 2005: 63 states that an experimental study is a study that is conducted by
manipulating the research object. The purpose of an experimental study is to investigate the effectiveness between a certain treatments to experimental class
and to control class as the comparison. Thus, the independent variable in experimental research is commonly called as experimental variable or treatment
variable. Meanwhile, the dependent variable is known as the outcome variable.

47 Referring to this research, the writer chose the experimental research
method because this research was related to the effectiveness of teaching model used as the independent variables and interest as the attribute variable in teaching
reading skill for the eighth graders of MTs NW Penedagandor This research involved three kinds of variables namely independent variable, dependent
variable, and control variable. The independent variable of this research was the teaching model.
The teaching model were the factors of this study which were manipulated, measured, and selected to know the effect and the relationship to the phenomenon
investigated. The teaching model used in this study were test taking teams and direct instruction model. These two different models were related differently for
the groups of students. In this way, the test taking teams group of students function as experimental group and direct instruction model of students function
as control group. Furthermore, the dependent variable of this research was students’ reading
skill for the eighth graders of MTs NW Penedagandor in the academic year of 20102011. The control variable of this study was students’ interest in learning.
This variable was also assumed as the secondary independent variable to the phenomenon investigated. In this study the writer is interested to investigate the
effect of independent variable X or teaching models on dependent variable Y or reading skill, in which the relationship between X and Y is influenced by the
attribute variable Z or students’ interest.
