This document describes a study that investigated misbehaved students' perceptions of non-verbal communication used in secondary school classrooms. The study utilized questionnaires to survey 30 misbehaved students about their perceptions of effective facial expressions and body movements for teachers to use. Results showed that maintaining eye contact and sitting beside students while teaching were the most effective non-verbal techniques perceived by misbehaved students. The study aimed to provide guidance for teachers on managing misbehavior through non-verbal communication.
