CHAPTER III RES EARCH METHODOLOGY
A. Place and Time of the Study
This research has been conducted in Sekolah Tinggi Agama Islam Negeri STAIN Zawiyah Cot Kala Langsa. This college is located on Jl.
M eurandeh - kota Langsa - Nangroe Aceh Darussalam, phone 0641 23129 fax 0641425129. It has 3 faculties, they are: Syari’ah Faculty,
Tarbiyah Faculty , and Da’wah Faculty. There is English Teaching
Department or Tadris Bahasa InggrisTBI in Tarbiyah Faculty. This Department is the biggest class and it has 3-4 classes annually, which
consist of 40 students in every class. This research has been done from January to M arch 2010.
B. Research Method
Experimental study is chosen in conducting this research. The purpose of experimental study is to determine cause-and-effect
relationship. Through experimentations, cause and effect relationship can be identified. Because of this ability to identify caution, the experimental
approach has come to represent the prototype of scientific method for solving problems Johnson and Christensen, 2000: 23.
By experimental study, the researchers find out the effect of at least one independent variable on one or more dependent variable. This study

involves three kinds of variables. The first is independent variable, it is experimental or treatment variable. The independent variable is the
teaching model X, and the term intelligence, as the second independent variable. The second variable is reading skill as dependent variable Y.
The writer supposes that the relationship between X and Y is changed by the level of a third factor Z, or intelligence.
This research uses quasi-experimental research design, quasi- experiments do not use proper random assignment, and typically they
recruit people in a way that can cause bias, such as using ―people on the
street‖. In compensation for this, other methods are used to increase the reliability and validity of the experiment, for example by using a control
group http:changingminds.orgexplanationsresearchdesign experiment types.htm. There are a lot of quasi-experimental designs types; one of
them is factorial design. The most appropriate experimental design of this research is
factorial design. This research design allows a researcher to study the interaction of an independent variable with one or more variables. This
design is possible to assess the effect or interaction Tuckman, 1978: 135. The factorial design is illustrated as follows:
