Four-Component Instructional Design

Four-component instructional design, commonly known as the 4C/ID model, is an instructional design framework developed by educational researcher Jeroen van Merrienboer from the early 1990s onward, most fully set out in his 1997 book Training Complex Cognitive Skills, intended for training complex, real-world professional skills that integrate many subskills at once, such as those required of pilots, surgeons or engineers, rather than simple, isolated tasks. The model organizes a course around four interconnected components: learning tasks, whole, meaningful, real-life tasks presented in a sequence of increasing difficulty; supportive information, the background knowledge needed to perform the non-routine parts of a task; procedural information, the step-by-step guidance needed for a task's more routine parts; and part-task practice, additional focused practice on subskills that need a very high level of automaticity. Van Merrienboer developed the framework partly as a response to instructional approaches that teach complex skills only as a collection of separate part-tasks, arguing this produces students who can perform individual pieces but struggle to integrate them into fluent whole-task performance, and 4C/ID has been applied extensively in vocational, medical and corporate training design.
