Redundancy and Coherence Principles

1. Redundancy and Coherence Principles EDIT 235 Lecture 12

2. Objectives • After completing this lecture you will be able to: • Describe the redundancy and coherence principles • Know when to use, or not use, audio in TBT/SPL • Know when to use, or not use, narration in TBT/SBL

3. Redundancy Principle • Is this an appropriate way to use audio? • Captivate (Interactive Simulations) • Inspired Learning • Why/Why not? • Redundancy Principle #1 • Avoid words as narration and identical text with graphics

4. Redundancy Principle #2 • Consider narration in special circumstances • Such as… • ________________________ • ________________________ • ________________________ No pictures Time to process narration Learner has difficulty processing

5. Coherence • Is this an appropriate way to use audio? • Excel • Why/Why not? • Coherence Principle #1: Avoid lessons with extraneous sounds • Such as… • ________________ • ________________ Music Sound Effects

6. Coherence • Coherence Principle #2: Avoid lessons with extraneous pictures • NexLearn Demo • ABB Totalflow NGC 8206 Simulation • Coherence Principle #3: Avoid lessons with extraneous words/text • NexLearn Demo • Pharmacy Tech Certification Preparation

7. Summary • Redundancy • Describe graphics with audio or text– not both • Use both to meet the learners needs • Coherence • Do not include unrelated music or sounds • Do not use unrelated graphics or animation • Use concise narrative (keep word count and complexity low)
