This report presents the initial findings from an ARC Linkage Grant, titled ‘Punish them or engage them? Identifying and addressing productive and unproductive student behaviours in South Australian schools’ (LP110100317), more commonly referred to as the Behaviour at School Study (BaSS). This phase of the study was conducted in 2011. We used the Behaviour at School Study Teacher Survey (BaSS Teacher Survey) to investigate the views of teachers about student behaviour in South Australian schools. This initial report summarises teachers’ views on student behaviour in the classroom.
