ther major issues involve the accepted hethods by which fidelity is measured. here are two major methods described the literature or fidelity measurement. The first is hrough mathematical measurement that alculates the number of identical lements shared between the real orld and the simulation; the reater the number of shared lentical elements, the higher the mulation fidelity. A second method measure fidelity is through a trainees' erformance matrix.

Liu et al$.(2009)$ identified two major methods for measuring fidelity. The first is a mathematical $($objective$)$ method that requires counting "the number of identical elements shared between the real world and the simulation; the greater the number of shared identical elements, the higher the simulation fidelity" $($p$.62).$ The second method involves a performance matrix that compares a human's performance in the simulation with that person's real$-$world performance, producing an indirect measure of fidelity.
