Outline of Presentation
Cognitive Load Theory Goal Free Learning Goal Free Learning in Multimedia Conclusion
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
Cognitive Load Theory
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

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

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.
