Simulation as aneducation tool has been used for at least 45 years 1. Using numerical simulation also has theadvantage of setting the student's attitude to understand the difficulties of the associated inverseproblems, which usually are the problems that demand attention in the upper division courses aswell as in the workplace. For a technology student, the transition from technical physics toengineering calculus physics is the crucial required paradigm shift in that student’s mindset.

The General Control Volume Approach With the introduction of the control volume at the very beginning of the class the instructor has to assume that students do not yet have a grasp of energy, work, mass flow heat etc. in a thermodynamics context. This can be a good thing as what is important, at this stage, is the generality of the general control volume approach. It will be used for various different properties throughout the course and to this end the “property” (B), of interest in our control volume analysis is initially chosen as something that students can readily associate with.

To achieve a diversity ofachievement levels in our interview subjects, we contacted students who had taken these coursesduring the Spring 2005 semester and received course grades of “C and lower” and “B/B-” in thesecond and third solicitations, respectively.

The gaming aspect ofthe project generates a high level of fun which enhances the learning process.
