A teacher observes a student's behavior in a kindergarten inclusion classroom to see how the student communicates with other children for an entire center time. The teacher makes the observations every 10 minutes for 30 seconds over the two-hour center time. The teacher then documents the behavior on a behavior log. Which of the following best describes the strategy the teacher is using?

A token economy is a behavioral management system in which desired behaviors are reinforced with tokens that can be exchanged for rewards. In this scenario, the teacher is not implementing a system of reinforcement through tokens but rather observing and documenting behavior, which does not align with the principles of a token economy.

Proximity control involves managing student behavior by maintaining physical closeness to the students, allowing the teacher to influence their actions through presence. The teacher's strategy does not include physical management or intervention but focuses solely on observation and documentation of behavior.

Nonverbal cueing refers to using body language or gestures to communicate expectations or reinforce behavior without verbal instructions. The teacher's approach of observing and logging behavior does not involve the use of nonverbal signals, as it is centered around systematic observation rather than direct interaction.
