(i) Pushing a table

(ii) A box on the table

(iii) Stopping a rolling ball

Identify the positive exemplars.

• A. (i) and (iii)
• B. (i) and (ii)
• C. (ii) and (iii)
• D. (i), (ii) and (iii)

Answer 1

Answer:

A. (i) and (iii)

• Concept Attainment: Teaching a concept (like "force") using examples.

• Exemplars: Good examples of the concept.

• Pushing Table: Force makes it move (from rest).

• Stopping Ball: Force makes it stop (changes motion).

• Relatable: Students understand these real-world examples.

• Contrast: Teacher would also show non-examples to clarify the concept further.
