Use of teaching aids – UGC NET Question

Statement A is correct because teaching aids help to concretise abstract ideas and make learning more meaningful for students. Statement B is also correct since appropriate aids capture and sustain learners' attention and interest. Statement D is correct as teaching aids should be selected and used in alignment with instructional objectives rather than in isolation. Statement C is incorrect because teaching aids need not always be expensive technologies and can often be improvised from low cost or local materials. Therefore the true statements are A, B and D only, making A, B and D only the correct combination.

Option A:
Option A includes statements A and B, both of which are correct about the value of teaching aids, but it leaves out statement D. Since D is also a true statement regarding the need to link aids with objectives, this option is incomplete. Hence A and B only cannot be accepted as the correct answer.

Option B:
Option B combines B and C and assumes both to be correct, but while B is true, C is a false statement that restricts teaching aids to expensive technological devices. Because teaching aids can be improvised with simple resources, accepting C as correct misrepresents the idea. This mixture of one true and one false statement makes the option unacceptable.

Option C:
Option C selects A, B and D, all of which are correct statements about the purpose and appropriate use of teaching aids. It recognises the role of aids in concreteness, attention and objective based planning while correctly excluding the false statement C. As this set contains only the true statements, A, B and D only is the right combination.

Option D:
Option D includes all four statements A, B, C and D and treats them as correct. By also including C, which is an incorrect statement about the nature of teaching aids, it fails to distinguish between true and false assertions. Therefore A, B, C and D only cannot be the correct response.
