Disruptive student behavior is a significant challenge in schools and a predictor of student failure. Effective classroom management is a crucial skill that middle level teachers must acquire to foster student engagement and learning. This qualitative study explored the experiences and perceptions of 35 middle level teachers in both general education and special education settings regarding effective classroom management techniques. Eight focus group interviews were conducted with 25 general education teachers and 10 special education teachers at one of five middle schools in Kansas, Missouri, or Utah. Focus group transcripts were analyzed using iterative qualitative content analysis to identify themes and subthemes. Findings revealed that effective classroom management includes teachers' use of appropriate positive and negative reinforcement, student buy-in to reward systems, positive immediate feedback to students, teachers' consistent follow-through with consequences, and positive teacher-student relationships. We also report similarities and differences between middle level general education and special education teachers' perceptions. Limitations and areas for future research are addressed.
