The correct answer is observation of cues.
Observation of cues refers to a communication strategy used by co-teachers, wherein they communicate with each other non-verbally. Co-teachers might come up with communication signals, such as hand gestures, facial expressions, code words, etc., to quickly convey short messages to each other. Non-verbal communication between co-teachers is important, since it is not always appropriate or possible to discuss students' performance during classroom hours. In this instance, when the circulating teacher holds up one finger when a student's work illustrates comprehension of the skill and two fingers up when a student's work does not illustrate comprehension, she is using observation of cues.
Ms. Grayson and Mr. Pullman co-teach in a 10th grade biology class. When students enter the room, they immediately begin work on an entrance ticket. While one teacher prepares the day's activity, the other teacher circulates the room while students work. The circulating teacher holds up one finger when a student's work illustrates comprehension of the skill and two fingers up when a student's work does not illustrate comprehension. It illustrates a observation of cues.
