This study set out to examine student misbehaviors confronted in preschool classrooms, intervention types to these misbehaviors, and the problematic areas that pre-service teachers experienced in preschool classroom management during teaching practice based on senior preservice preschool teachers' observation and experiences during teaching practice course. To this end, in this case study, data were collected from six pre-service preschool teachers through a semi-structured form and weekly meetings. The data were analyzed through descriptive analysis. Some of the basic findings of the study indicate that: peer violence, bad language, not participating to activities and constant yelling/crying are the most prevalent misbehaviors at preschool level; relaxing/punishment corner, one-to-one talking/forcing to apology, and raising voice are the most frequent intervention types. The number of students and catering to children's levels are the most frequent problems the pre-service teachers experience in teaching practice. The problems are related to intrinsic and extrinsic factors. The results are discussed with the literature and recommendations are made.
