Classroom discipline is a topic of international interest and teachers are bombarded with advice regarding how to and why they should manage children's behaviour in their classrooms. This paper draws on data related to classroom discipline gathered from a detailed classroom observation schedule, teacher interviews, and field notes with four purposively selected kindergarten teachers working in Hong Kong with children aged 5-6 years. The findings of this qualitative case study show that the teachers were concerned about disciplining children to ensure good behaviour. They expected all children to follow the rules and used characteristic discipline strategies such as stating expectations and "praising the opposite" to maintain good behaviour. The paper discusses these findings in light of the Westernisation of kindergarten teaching practices in Hong Kong.
