Low cost teaching aids – UGC NET Question

Option D – low-cost teaching aids Low-cost teaching aids are materials that can be prepared or obtained cheaply using locally available resources. Charts, flashcards and simple models are often produced with paper, card and other inexpensive items by teachers or students. They make lessons more concrete and interesting without requiring advanced technology or large budgets. Hence, the aids listed in the stem are correctly classified as low-cost teaching aids.

Option A:
Virtual teaching aids are digital or computer-based tools such as simulations or interactive software, which are not mentioned in the question. Although they can be effective, they usually require electronic equipment and infrastructure, so this option does not fit the examples given.

Option B:
Sophisticated teaching aids typically involve advanced technology or specialized equipment, for instance multimedia projectors or virtual reality systems. Charts and flashcards are simple devices and do not fall into the category of sophisticated aids, so this option is inaccurate.

Option C:
Psychological teaching aids is not a standard category; psychological principles may inform how aids are used, but the term does not describe physical materials like charts and models. Therefore, it does not accurately label the examples in the stem.

Option D:
Low-cost teaching aids can be very powerful in resource-constrained classrooms because they are easy to make, repair and adapt. They promote creativity in teachers and can be tailored to local contexts. Since charts, flashcards and homemade models match these characteristics, this option names them correctly.
