Internal Noise: The student isn't paying attention.
This class is so boring...wait what did the teacher just say?
I didn't hear what she said
Channel: Face to face
Could you please go over the products of photosynthesis?
Feedback: The student responds to the question.
The teacher is the sender and is sending the message through a face to face channel. She is encoding that she wants students to ask questions if they have any. A barrier to communication is the external noise coming from the classroom next door.
The products of photosynthesis are glucose and oxygen.
Next I have an important announcement.
The students are the receivers. One of the students is decoding the message while another student has internal noise because he is not paying attention and didn't hear the question.
I should listen since she said it's important.
The student gives feedback by responding to the question. She sends the message through a face to face channel.
Today's Lesson: Photosynthesis
Coming up soon you will have a test over everything we've learned so far this year. This test isn't difficult, but you will need to study if you want to get a good grade. It will count for 50% of your grade so it is very important.
Does everyone understand?
Encoding: This announcement is important so everyone should listen.
The teacher responds to the student's question and sends out another message. She encodes that everyone should listen.
The student decodes that she should listen and pay attention to what the teacher is saying.
The teacher demonstrates ethical responsibility by conveying honest information about the test, informing the students in advance, and telling them that they need to prepare for the test.
