III. RESEARCH METHOD
This research is intended to find out whether Three-Step Interview can be used to increase
students’ speaking achievement or not. This chapter includes the research design, the population and sample, data collecting technique, research
procedure, criteria for evaluating students’ speaking, reliability, and validity of
the instrument, speaking test, data analysis, and hypothesis testing.
3.1 Research Design
This research is quantitative research. It was carried out to see and find out the result of implementing three-step interview in increasing students
speaking achievement. In conducting the research, the researcher used time series design by giving different topics in every treatment and every test. The
researcher used one class where the students gave three times treatment and three times post-test. The research design can be represented as follows :
