This article describes a specific effort to create a multimedia training technology (A Child Protective Service Investigation Simulator or CPS Simulator) for a representative group of street-level public servants--child protective service (CPS) workers. The article first provides some background on why bias in this area is a significant problem, then the basic features of the technology are outlined and a rationale for the development of the software within the current environment for developing educational technology is presented. The bulk of the article discusses the research on which the initial design of the CPS Simulator was based, and how the ultimate design of technology incorporates characteristics of situated learning environments and constructivist approaches to learning.
