There are various types of research methodologies. However, I'm going to focus on experimental research since it is related to my research proposal.
Below is the conceptual framework or the research design for experimental research.
This design is the randomized pretest-posttest control design.
Two groups of subjects are used, with both groups being measured or observed twice. the first measurement serves as pretest, the second as the posttest. For my research purpose, I will randomly select 60 students from the average proficiency level and these students then will be divided into two groups: 1)experimental and 2) control group.
Test-retest method is used in order to secure the reliability of the findings.
In a research, there are possibilities that the dependent variables or the results would be affected by other variables. The variables which may influence the dependent variables are called the extraneous variables. It is very important to eliminate or minimize these extraneous variables in order to ensure the validity and reliability of a study.
Variables, validity and reliability will be further discussed in other entries.
