· Review the data provided in the articles by Ciftci, H. D., & Temel, Z. F. (2010) and Evmenova, A. S., Graff, H. J., Jerome, M. K., & Behrmann, M. M. (2010). Note the use of A-B-A-B and multiple baselines approaches in these studies and how you might defend the use of these approaches.

· Review the course text readings for this module, as well as the media. Think about the concepts and ideas present in these Learning Resources and how they might inform your interpretation of the data in the research studies.

Compose a 4–5 page paper in which you:

· Defend the use of A-B-A-B and multiple baselines designs in the Ciftci, H.D., et. al. (2010) and Evmenova, A.S., et. al. (2010) studies. In your response, provide a rationale for using a different approach to each study.

· Based upon the graphics, analyze the data presented in each study. Explain what the data tells you, your interpretation of the results, and the interventions the data suggest.

In this media program, Dr. Terry Falcomata explains Single-Subject Design.

Focus on single-subject design as a quantitative research approach that allows researchers, clinicians, and educators to establish experimental control in answering a question of some clinical or educational relevance. Reflect on how the use of single-subject design can demonstrate that an intervention or program reliably produces positive changes in important behaviors or skills.

Note: The approximate length of this media piece is 4 minutes.

In this media program, Dr. Terry Falcomata explains the A-B-A-B Single-Subject Design.

Focus on the example of the experiment that uses an A-B-A-B single-subject design. Note that it is sometimes referred to as a withdraw or reversal design. Consider how it uses repeated measures of a behavior strategically across baseline and intervention conditions.
