The model is first defined as an abstract (digital) or concrete (analog) representation of a real system in which the
variables are clearly specified and their behaviour around a phenomenon is similar to that of the system being
modeled. (Arthur, Malone & Nir, 2002). Reality is generally defined as an individual’s perception of a system,
event, person, or object. This perception can vary and be interpreted differently across individuals. Milrad (2002)
states that a model which supports learning has to feign real situations and provide feedback to participants which
will allow for an improved knowledge of reality. Reality can take on several forms but, as for the concept of
simulation, it generally reproduces a dynamic system (Arthur et al, 2002). Moreover, Cioffi et al (2005) noted that
the simulation offers a miniature version of a sphere of concrete activities in real life. Medley et Horne (2005)
findings completely agree with our research when they maintain that simulation is a realistic model that can simulate
real-life scenarios. Therefore, educational simulation is similar to real life (Martin, 2003; Swanson & Ornelas,
2001) and offers a type of controlled reality, where learners can experiment with aspects of reality that otherwise
would be impossible to study outside of real life.
