Disruptive behavior in the classroom can negatively impact the learning environment. Some types of disruptive behaviors include monopolizing class discussions, excessive talking with other students, challenging the teacher's authority, lateness, sleeping in class, and using electronic devices. This behavior interferes with the teacher's ability to teach and the students' ability to learn. It requires the teacher's time and attention to address the disruptions, taking away from instructional time. Disruptive behavior by one student can encourage similar behavior from others and compromise the teacher's authority. It can also result in lower grades for students and require schools to dedicate resources to stopping disruptions instead of improving education for all.
