Communication is an integral part of the teaching-learning process. Teaching is a social activity that involves both the teacher and the learners. It is therefore important, that two-way communication exists between them to trigger learning.The classroom is an excellent example of a place of communication in group situations where teachers spend hours communicating with students to share information and knowledge.Types of communication in the classroom:Verbal Communication: Such a type of communication in which the message is conveyed either verbally or in written form is called verbal communication.Verbal communication is the expression of ideas with the help of speech sounds or written symbols combined into words, and words into sentences that could effectively convey meaning. Non-verbal Communication:You might have seen teachers intentionally using their body parts during their lectures. Teachers nod their heads, blink their eyes, stretch their hands, walk throughout the class, point their hands, make eye to eye contact, and so on.While doing such intentional body movements (body language), they do interact and communicate some message with the students. Such communication is known as non-verbal communication.Non-verbal communication involves conveying a message without using words, either spoken or written. Or else the communication between two or more persons using facial expressions, postures, gestures, body language, eye gaze, etc., is called non-verbal communication.Hence, we can conclude that body language, gestures, and eye gaze are examples of nonverbal communication.
