Module 5 E-Learning

Worked examples are instructional tools that provide a step-by-step demonstration of how to perform a task or solve a problem. They are designed to facilitate learning transfer, whether it be far transfer, which involves teaching broader strategies, or near transfer, which allows learners to understand a task based on their knowledge of a similar one.

How to Create Worked Examples

Provide clear and concise descriptions of each step
Show each step in the process of solving the problem
Use fully representative problems

Unknowns in Worked Examples

How can active observation be used in workplace learning
How to design and use modeling examples
How does multi-media get worked into the example
Do modeling examples benefit from fading or other strategies
When to use fading rather than self-explananation questions
Used together they seem to cause cognitive stress
Both are effective alone

Worked Examples Definition

A step-by-step demonstration of how to perform a task or solve a problem

Design Guidelines for Worked Examples

Require active comparisons using the varied types of examples
Helps foster abstraction skills
Leads students in understanding similarities
Include self-explanation questions for better results
Helps internalize knowledge
Aids in abstraction skills
Promotes understanding by expecting students to explain the answer
Use varied types of examples to provide additional context
Illustrate the same guidelines in different ways
Helps develop abstraction skills

Principles of Worked Examples

Fade from worked examples to problems
Promote self-explanations
Encourage active observations
Add self-explanation questions to worked examples
Include instructional explanation of worked examples as needed
Mathematical content
When there are no self-explanation questions
Conceptual understanding more important than problem solving
Apply multimedia to examples
Give learners control of the pacing
Present steps in meaningful groups
Present steps with integrated text
Present steps with audio only rather than audio and text
Illustrate worked examples with appropriate visuals
Support learning transfer
far transfer - teaching strategies rather than tactics
Near transfer - the ability to understand how to perform a task based on knowledge of a similar task.

Benefits of Worked Examples

Helps learners develop strategic skills
Help learners build procedural skills such as performing tasks
