Schnotz et Rasch (2005: 48) consider that the educational character of simulations includes two types of functions
that are based on a decrease in the cognitive load: enabling function and facilitating function. Enabling function: “If
they reduce the cognitive load of tasks in order to allow cognitive processing that would otherwise be impossible,
then animations have an enabling function”. Facilitating function: “If they reduce the cognitive load of tasks that
could otherwise be solved only with high mental effort, then animations have a facilitating function.”
