Cognitive Load Theory

Supports 2 learning goals :The acquisition of Schema

- Memory / Storage Organizer- Reducer of Working Memory Load

Automization

- Movement from Controlled (Conscious)- Processing to Automatic Processing

Working Memory

Cognitive Load

As Total Cognitive Load increases the burden on Working Memory increases

Learning Task

Cognitive Load Theory

Working Memory

= Total Cognitive Load

Learning Task

Intrinsic Cognitive Load +Extraneous Cognitive Load + Germane Cognitive Load

Cognitive Load TheoryTypes of Cognitive Load

Intrinsic Cognitive Load

Element Interactivity

-the extent to which elements of tasks must be learned in relation to the elements’ relation between other elements

Low Interactivity: Elements can be learned independently of other elements

High Interactivity: Tasks cannot be learned without simultaneously learning its connections with large numbers of elements

-Learner’s degree of task automation effects the number of elements to be learned thereby effecting degree of interactivity

Cognitive Load Theory

Germane Cognitive Load

Effort that contributes to the construction of schemas

- Worked Examples

- Goal Free Learning

Increasing the germane load increases learning, but only when…

1) Total cognitive load is within capacity of Working Memory

2) Intrinsic Cognitive load (element interactivity) is high

The Goal-Free Design

Increases Germane Cognitive Load Increases Extraneous Cognitive Load

ie Solve for Xi.e. Calculate as many variables as you can

Only problem state held in WM All Goals & Sub goals held in WM

Effective for Problem Solving/ Not learning

Effective for Learning/Schema Creation

Sub-Goal: Angle DEA

Sub-Goal: Angle DBG

Learners make a higher number of errors on the sub-goal stage, when more elements are in working memory, than in the goal stage.

Since no sub-goals, only goals, the number of the elements simultaneously in WM is limited. Learners make less errors during goal-free problem solving due to the minimized element interactivity.
