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
redundancy principle
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
redundancy principle 2
Redundancy Principle #2
  • Consider narration in special circumstances
  • Such as…
    • ________________________
    • ________________________
    • ________________________

No pictures

Time to process narration

Learner has difficulty processing

coherence
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

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
summary
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)
