Which behavior is least likely to be classified as a disruptive behavior in a classroom?

The behavior described as consistently completing homework is the least likely to be classified as a disruptive behavior in a classroom setting. Completing homework demonstrates a commitment to learning and engagement with the material being taught. It typically indicates that a student is prepared and taking their education seriously, fostering a positive classroom environment.

In contrast, talking out of turn, making loud noises, and refusing to follow directions all disrupt the flow of instruction and can negatively impact both the teacher's ability to teach and other students' ability to learn. These behaviors draw attention away from instructional activities and can create an atmosphere of chaos or disrespect in the classroom, making them clearly disruptive.
