Title: Dual Coding Theory

Have you heard about dual coding theory before?

Dual coding theory assumes that humans can process incoming knowledge from both verbal (text / language-based) and non-verbal (visual, smells etc.) channels simultaneouly. This is a powerful idea and can help us design instruction for our learners in alignment with how human brains learn.

Q: What is dual coding theory?
- A theory about coding computer programs
- A theory about how the brain processes and recalls information using two cognitive subsystems (correct)
- A theory about coding language structures

Q: According to dual coding theory, what are the two cognitive subsystems of the brain?
- Logical and emotional
- Short-term and long-term
- Verbal and non-verbal (correct)

Q: How does dual coding theory suggest that verbal and non-verbal systems interact with each other?
- They compete for dominance
- They are completely independent
- They are functionally separate and constantly interact (correct)

Q: What was one of the important predictions from dual coding theory?
- Verbal and non-verbal systems have additive effects on memory (correct)
- a. Verbal and non-verbal systems have conflicting effects on memory
- Dual coding theory has no impact on memory

Q: How can teachers support deeper processing according to dual coding theory?
- By focusing only on verbal representations
- By encouraging learners to create mental images of concepts (correct)
- By neglecting the non-verbal system during teaching because it creates confusion.
