The overall aim of this study is to understand the impact of negative emotions on student behavior, and how students manage these emotions.The general hypothesis is that the upsurge in violence in schools is linked to the lack of genuine mechanisms for managing negative emotions. The study was based on Daniel Goleman's theory of emotional intelligence. The study was carried out on a sample of 400 students, using probability sampling.We collected data on this school population and sent them a questionnaire. The results of this study show that controlling negative emotions can prevent violence in the school environment. The present study argues in favor of raising students' awareness of their involvement in the process of eradicating violence in the school environment.
