In this research, it is aimed to explore the beliefs and the views of preschool teachers about discipline, classroom management, and dealing with disruptive behaviors in their classrooms. The study was done through case study methods as one of qualitative research methods. It was conducted in 2012-2013 educational years and with 3 preschool education teachers who were selected from a preschool dependent on the Ministry of National Education. The data was gathered through unstructured in-class observations, semi-structured interviews with the teachers, and document analysis of teachers' plans related to daily routines. After transcription, the data were transferred to NVIVO 8 program, which is a qualitative data analysis tool, and its analysis was made through content analysis. As a result of study, it was found out that there are clear distinctions with teachers' classroom practices and their classroom management discourses although there were some similarities between their beliefs and practices. In contrast to their beliefs, the teachers were observed to use more traditional classroom management strategies for the disruptive behaviors.
