The Four-Component Instructional Design model or 4C/ID-model working assumption is that complex learning platforms can be described by four basic components (van Merriënboer, Clark, et al., 2002), which in turn creates a blueprint for the design of the learning platform:
<b>Learning Tasks</b> — concrete, authentic, whole task experiences that are provided to learners in order to promote schema construction for non-recurrent aspects and, to a certain degree, rule automation by compilation for recurrent aspects.
<b>Supportive Information</b> — information that is supportive to the learning and performance
of non-recurrent aspects of learning tasks
<b>JIT Information</b> — information that is prerequisite to the learning and performance of
recurrent aspects of learning tasks
<b>Part-task Practice</b> — practice items that are provided to learners in order to promote rule
automation for selected recurrent aspects of the whole complex skill
