CHAPTER 3: METHODOLOGY

This chapter introduces a description of the procedures of the study in

terms of the research design, the population, the participants, the study

instruments and the study procedures.

3.1. Research methods

The researcher followed the quasi-experimental research design with a

paired sample in which the researcher suggested four hypotheses and

tested them using pre- and post-test. The quasi-experimental design is

usually used to evaluate the impact of an ongoing program on one or

more indicators of output or outcome.

The statistical analysis of the collected data and the findings of the

research were tackled according to the research questions and

hypotheses by using the Statistical Package for Social Sciences (SPSS).

The data was statistically analyzed using the following statistical

analyzing tools:

a. Cronbach’s Alpha was used to measure the reliability of the test.

b. Cooper coefficient formula was used to calculate the coefficient

reliability between the observers.

c. Paired sample t-test was used to answer the questions and to test

the hypotheses.

Regarding the number of students in the test group is 30 students and the

control group is 30 students from 2 classes at Can Tho University.
