Read the following statements and choose the correct option :

Assertion (A) : Teachers should ask students to identify their own examples and non-examples of the concept for strengthening the concept.
Reason (R) : Thinking of examples leads to strengthening of the concept while non-examples tend to confuse the students.

  • A.(A) is true, but (R) is false.
  • B.Both (A) and (R) are true, but (R) is not the correct explanation of (A).
  • C.Both (A) and (R) are false.
  • D.Both (A) and (R) are true and (R) is the correct explanation of (A).

Answer: A

(A) is true, but (R) is false.

Asking students to generate their own examples and non-examples is a well-established way to strengthen a concept. Examples show which features a concept must have; non-examples show its boundaries. To understand 'mammal', a child should see why a whale is one and why a penguin is not.

The Reason is wrong because non-examples do not confuse students. Properly chosen, they sharpen the concept by making its defining attributes clear. Since the Reason misstates the value of non-examples, the options calling it true are incorrect.
