Projected teaching aids – UGC NET Question

Projected teaching aids require a projection device,like an overhead projector or LCD projector,to display images or text on a screen. Devices such as LCD projectors and document cameras belong to this category because they project enlarged visuals to the whole class. These aids combine visual clarity with the teacher’s explanation. Therefore,the stem points to projected teaching aids.

Option A:
Projected aids help enhance visibility,illustrate diagrams and show multimedia content,which matches the use of LCD projectors described in the question.

Option B:
Non projected aids include charts,models and posters that can be seen directly without projection,and thus do not match the devices named.

Option C:
Community-based aids refer to resources drawn from the local community,such as field visits or local experts,not classroom projection equipment.

Option D:
Purely verbal teaching does not involve visual media at all,so it is the opposite of what projectors and document cameras provide.
