UGC NET Questions (Paper – 1)

Multi channel communication refers to the use of more than one channel or mode to transmit the same or related messages. A teacher who combines oral explanation with slides and videos engages both auditory and visual channels. The stem explicitly highlights this simultaneous use of different channels,so multi channel is the correct choice.

Option A:
Using multiple channels can improve comprehension and retention because learners receive reinforcing cues through different senses. This is especially useful for complex topics,which is why such teaching is encouraged in UGC NET pedagogy.

Option B:
Linear describes a direction of flow from sender to receiver but does not indicate how many channels are used.

Option C:
One way highlights absence of feedback and says nothing about diversity of channels. A multi channel presentation can still invite questions and two way interaction.

Option D:
Grapevine refers to informal organisational networks and is unrelated to planned classroom multimodal instruction.
