Feedback is the response of a receiver to a message they get from the sender. The form of feedback varies with the way of communication. Sometimes feedback could be non-verbal like a smile, sigh, or facial gesture. This kind of feedback is immediate and direct. It often appears during a face-to-face conversation. Most of the time, feedback is verbal. Verbal feedback can be oral as when you react to a colleague's talk with questions or comments, or it can be written when you reply to an e-mail or online message, or when you comment on a student's essay. Written feedback is less immediate. Sometimes it may be delayed for days. When people send a message, they wait for feedback. Effective communicators pay close attention to feedback. They want to be sure that the message has got through to the right person and that the receiver has understood the message as it is intended. They also want to know the receiver's reaction to what they share. 1. How essential is feedback? st 2. What form(s) is feedback? 3. Where can you see non-verbal feedback? 4.
