What is cognitive load theory?
How we learn is constrained by our biology. Knowing what this entails is an enormous help in designing effective teaching. Cognitive load theory spills the beans on what our limits are and how teachers can get reduce their impact.
This free poster sets out nine important components of cognitive load theory. These include:
- Working memory limits – our working memory comprises the attention we use to think. It is very limited and gets jammed as we attempt to get new information organised and into long-term memory.
- Novices and experts – novices and experts think in different ways. Experts easily and fluidly use elaborate schema in their long-term memory to overcome the limits of working memory. Novices, alas, can’t.
- Borrwed knowledge – borrowed knowledge refers to already existing organisation of information held by experts. There is little sense in hoping that novices can succeed in duplicating this achivement.
Other points covered include:
- Intrinsic vs extrinsic load
- Transient information effect
- Split attention
- Modaility effect
- Worked example
- Guidance fading effect
