Phase 1: Prepare
Step 1 Warm-up recall
From M5.L2: what is the order of fading?
Private: nothing you type here is sent or stored.
Step 2 Learning goal
By the end of this lesson you can:
- give a concrete example of an abstract idea (Foundation);
- explain dual coding (Core);
- build and check an example table (Core).
Phase 2: Teach
Step 3 A familiar example
The idea of "average" is abstract. Saying "4, 6 and 8 average 6" gives you something to picture and check.
Step 4 Clear explanation
Abstract statements are compact but hard to hold. A concrete example gives the idea something to attach to. Good practice is to use several examples that differ on the surface but share the same idea, so you notice what stays the same.
| Idea | Abstract statement | Concrete example |
|---|---|---|
| Opportunity cost | Choosing one option gives up the next best | Spending Saturday studying means giving up a day working |
| Average | The sum divided by the count | 4, 6 and 8 give 18 / 3 = 6 |
| Spacing | Gaps between reviews help retention | Reviewing on days 3, 5 and 9, not all on day 3 |
Check the middle row: 4 + 6 + 8 = 18 and 18 / 3 = 6. Dual coding (Paivio) is the idea that words and images are handled in partly separate ways, so an idea stored both ways has two routes back.
You need not draw well: a rough diagram, timeline or table is enough. The drawing is useful because making it forces you to decide how the parts connect. Pictures help when they carry meaning; a decorative picture does not, and may distract. Avoid cramming a picture and a long spoken text on the same item, which can overload working memory; see working memory.
Step 5 Worked example (4 marks)
Give a concrete example of an average of 5 using three numbers, and check it.
- Choose three numbers adding to 15: 3, 5 and 7. (1 mark)
- Add: 3 + 5 + 7 = 15. (1 mark)
- Divide by 3: 15 / 3 = 5. (1 mark)
- Answer: 3, 5 and 7 average 5. (1 mark)
Phase 3: Practise
Step 6 Learner practice (instant-marked)
1. A concrete example helps because it:
It anchors the abstract.
2. Dual coding means storing an idea in:
Two routes in.
3. The average of 4, 6 and 8 is:
18 divided by 3.
4. A good picture for study is:
Meaning matters.
Phase 4: Close
Step 7 Recap
- Concrete examples anchor abstract ideas.
- Use several different examples of one idea.
- Rough diagrams give a second route in.
Step 8 Exit ticket (ungraded)
Give a concrete example of the spacing effect.
Private: nothing you type here is sent or stored.
Step 9 Go further (Extension)
Build a three-row table of idea, abstract statement and concrete example for your course.
Common mistakes
| Mistake | Why it fails |
|---|---|
| Using one example only | Use several that differ. |
| Decorating notes | Draw to show connections. |
| Not checking the example | Work it through. |
Limits. Claims that people have fixed "visual" or "verbal" learning styles are not well supported; dual coding is about how ideas are encoded, not about types of learner.
