This paper attempts to explore and identify the characteristics of an effective teacher who teaches English as a second language to 10 year old students from different ethnics, various social economic background and multi-level language ability, at a private primary school in Malaysia. The study focused on classroom management using a case study methodology where data was collected using both interviews and classroom observations. The findings concur with previous literature reviews on effective teacher models whilst providing in-depth details on what transpires during classroom activities, thus clarifying further the meaning of effective classroom management. The implications of this study suggest the need to include six new classroom management behaviours of an effective teacher. Further research is warranted to help policy makers and school administrators in identifying the significance of these behaviours for the selection and training of future teachers.
