Discussion: experimental, quasi-experimental, and correlation | EDSD 7072 – Research Methodology for Special Education | Walden University

For this Discussion you will examine the use of each quantitative approach to research for a special education problem.
To prepare:
ú Reflect on this module?s media and the reading from the Rumrill, et. al. (2011) course text. Consider the various quantitative research designs and the implications of each on special education research.
ú Think about a special education problem that you would address, if it were ethical, using an experimental design. Consider how you might also use a quasi-experimental or correlational design to study the problem.
An explanation of the special education problem you would choose to study using an experimental design if it were ethical and why. Then, explain how you would study the same problem using a quasi-experimental or correlational research approach. Finally, provide a rationale for the method you believe to be the best choice.
Support your response with specific reference to at least two peer-reviewed outside resources as well as the Learning Resources and/or personal experience.

Chapter 6, ?Quantitative Research Designs? ÿÿÿÿÿ(pp.136?152)
Focus on the spectrum of relationship and descriptive studies. ÿÿÿÿÿNote correlational designs and causal comparative studies. Develop an ÿÿÿÿÿunderstanding of surveys, case studies, program evaluation, archival ÿÿÿÿÿresearch, longitudinal studies, empirical literature reviews, and ÿÿÿÿÿmeta-analysis.
