Briefly describe to the class the project you and your team are working on for your RFP.

The RFP my team is doing is about anti-bullying. The Olweus Bullying Prevention Program (OBPP) has been implemented in Redford Public School System for a full calendar year. They are wanting an evaluation to determine the effectiveness of the program and if it is meeting objectives of the program. The programs objective validity will be a six-month evaluation process and will allow for individuals to make any necessary alterations and improvements. The program presents a very ideal anti-bullying prevention and intervention based on the elements of a well-established model with OBPP (Olweus & Limber, 2010). With this RFP, it situates an evaluation team in the posttest state which could potentially threaten internal validity.

Describe a situation for which a single-group design might be considered for an evaluation of the general program situation of your RFP (e.g., school anti-bullying program). Why might it be appropriate in this situation? Explain.

Given your example, explain the strengths and limitations of a single-group design for use in this evaluation.

Would you choose a posttest only or pretest-posttest design? Why?

How would you try to deal with threats to internal validity as part of your planning?
