Method
Research Design
Design and development research (Richey & Klein, 2007) was used in this study to address the va-lidity of the Jeffries framework. According to Richey and Klein (2007) “model validation is an empirical process that demonstrates the effectiveness of a model’s use in the workplace or provides support for the various components of the model itself” (p. 12). The study of a design model can be accomplished through “validation of the impact of the products of model use” (Richey, 2005, p. 174). The current study focused on documenting the Jeffries model during simulation design, implementation, and evaluation
