Ms. brown always ends group work activities by standing at the front of the room facing students and turning on the overhead projector. ms. brown is using this position and behavior to:

signal appropriate student behavior.

Explanation:

Using nonverbal signals can create a communication that is done swiftly,quietly and discreteely.Signaing means you don't have to shout to the students when you send the message but you just use the body langauge or non verbal communication.
