CPI Multimedia & Visual Learning Aids 2 — Questions and Answers
Question 1: When designing a slide presentation for adult learners, the 6x6 rule recommends limiting slides to:
- 6 slides per topic and 6 topics per session
- 6 bullet points per slide and 6 words per bullet (Correct answer)
- 6 images per slide and 6 slides per hour
- 6 fonts per presentation and 6 colors per slide
Correct answer: 6 bullet points per slide and 6 words per bullet
The 6x6 rule states each slide should have no more than 6 bullet points with no more than 6 words each to maintain clarity.
Question 2: Which principle explains why learners retain more from words and pictures together than from words alone?
- Cognitive load theory
- Multimedia learning principle
- Dual coding theory (Correct answer)
- Elaborative interrogation principle
Correct answer: Dual coding theory
Dual coding theory, proposed by Allan Paivio, holds that combining verbal and visual information creates two memory traces, enhancing retention.
Question 3: A CPI instructor wants to reduce extraneous cognitive load in a video tutorial. The BEST approach is to:
- Add background music to maintain engagement
- Include decorative animations between each step
- Remove irrelevant graphics and keep narration focused (Correct answer)
- Display all steps simultaneously on screen
Correct answer: Remove irrelevant graphics and keep narration focused
Removing irrelevant visuals and keeping narration on-topic eliminates extraneous cognitive load that competes with learning.
Question 4: In multimedia instruction, the coherence principle states that learning is improved when:
- Background music matches the lesson theme
- Interesting but irrelevant material is excluded (Correct answer)
- Graphics are placed adjacent to related text
- Narration and on-screen text are presented simultaneously
Correct answer: Interesting but irrelevant material is excluded
The coherence principle (Mayer) holds that seductive details—interesting but irrelevant content—hurt learning by diverting attention.
Question 5: An instructor is choosing between an animation and a series of static diagrams to explain a mechanical process. Research suggests:
- Animations always outperform static diagrams for procedural content
- Static diagrams are always superior because learners control pacing
- Animations are only beneficial when the process is too fast to observe in reality (Correct answer)
- The choice has no measurable effect on comprehension
Correct answer: Animations are only beneficial when the process is too fast to observe in reality
Research shows animations offer the greatest advantage for processes that occur too rapidly or too slowly for real-world observation.
Question 6: Which color contrast ratio is recommended by WCAG 2.1 AA standards for normal-sized text in instructional materials?
- 2:1
- 3:1
- 4.5:1 (Correct answer)
- 7:1
Correct answer: 4.5:1
WCAG 2.1 AA requires a minimum contrast ratio of 4.5:1 for normal text to ensure readability for users with low vision.
Question 7: When embedding video into an instructor-led training session, the recommended maximum clip length to maintain learner attention is:
- 30 seconds
- 2–3 minutes
- 6–9 minutes (Correct answer)
- 15 minutes
Correct answer: 6–9 minutes
Research on video engagement, including MIT studies, indicates cognitive attention peaks in the 6–9 minute window before significant drop-off occurs.
