Feedback

                                                                      Noise

            The response of the receiver can be verbal or non-verbal. In the above example, a smile would be a positive
            feedback to convey ”Yes, understood” whereas rolling your eyes and fidgeting with the objects around will indicate
            “not understood or not interested”. The teacher can also ask a question to know the status of the class and the
            feedback will be the answer conveyed orally or in written form.
            The process of giving a feedback should follow the given steps:
            1. The message should be clear, and interpreted properly by the receiver.

            2. If the message is not clear, then clarify from the sender by asking questions.
            3. Always refers to the original form of message to understand it clearly.
            4. Convey the response in the form of feedback to the sender.


            1.6.2. Types of Feedback
            There are different types of feedback given by the receiver depending on the type of information and the message
            that needs to be conveyed. Each type of feedback has its own features. Let us learn about different types of
            feedback in detail.
            Formal and Informal Feedback

            Formal feedback follows a predefined format or blueprint to construct the structure of the feedback. It is also a
            time-consuming process. For example,

               • “Congratulations! Keep it up.”                     • “Sorry! No entry without a ticket.”
            Informal feedback is most of the times spontaneous oral feedback that does not follow any specific pattern or
            predefined blueprint. For example,
               • “Hi! Your son has done really well this time in exams.”
               • “Listen, You people cannot go inside without a ticket.”

            Descriptive and Non-Descriptive Feedback

            Descriptive feedback is a detailed analysis in written or oral that helps the learner understand strong and weak
            points. Descriptive feedback is a very powerful tool for students in achieving successful learning. It helps a student
            find out strong points in academic and non-academic areas, areas where they need to improve and steps to follow
            to improve their weak points. For example,
               • A Science Teacher giving a descriptive feedback to the students by explaining the mistakes done by a student in
              his paper with detailed analysis and suggestions for each mistakes, “Questions 3 and 4 are not written properly.
              You need to make a diagram along with the answer and elaborate on the points more related to the functions each
              part performs.”
               • An Employer giving a detailed analysis of the project report submitted by its subordinate, “The report needs
              more focus on the marketing areas, data analysis  charts with areas highlighted in terms  of maximum  and
              minimum sales made by you. Also, specify the scope of improvements and inputs required by the management”.
