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.

The correct option is (A) is true, but (R) is false.

Analysis of Assertion (A):
Assertion (A) states that teachers should ask students to identify their own examples and non-examples of a concept for strengthening that concept. This statement is true. Encouraging students to generate both examples (instances that belong to the concept category) and non-examples (instances that do not belong to the category but share similar attributes) helps deepen their understanding, clarify boundaries, and prevent misconceptions about the concept.

Analysis of Reason (R):
Reason (R) states that thinking of examples leads to strengthening of the concept while non-examples tend to confuse the students. This statement is false. Non-examples do not confuse students; rather, they serve a vital pedagogical purpose by contrasting what a concept is with what it is not, thereby highlighting essential defining characteristics and removing ambiguity.

Therefore, Assertion (A) is true, but Reason (R) is false.
