Prior research suggests that the structuring or modeling of information
has both cognitive effects
(allows a complex set of information to be dealt with as one element)
and motivational effects
(improves the meaningfulness of the information and related task)
(van Merrienboer and Sweller 2005).
Models that emerge from the structuring
of information also serve
as useful sources for explaining
and justifying decisions and actions
(Sweller 1994).
