This paper establishes a framework and guidelines for determining the right fidelity for positive learning transfer within serious gaming environments. We characterize types of activities found in several video gaming environments that lend themselves to promote skills for high cognitive functioning in complex domains and then analyze what type and level of fidelity would be required for successful learning transfer. To inform the discussion we draw from several research and methodological sources. The work in Cognitive Task Analysis (Crandall, Klein, Hoffman 2006, Klinger 2003) informs our definitions of what it means to perform at a high level of proficiency. The work of Goettl, Ashworth and Chaiken (2007) establishes the differences between high cognitive and high physical fidelity; the research and practice in developing simulation Intelligent Tutoring Systems (Chandler, Owens 2003, Anthony, Ashworth 2006) highlights cases when the type and level of fidelity enhances or inhibits learning transfer. The paper introduces a framework to establish standards and guidelines for optimal learning transfer within gaming environments spanning a variety of types and levels of fidelity.
