'Motivation' is a significant concept for teachers and students during programmes of learning which lead explicitly to high stakes assessments and examinations. This systematic literature review surveys current research evidence to find out how secondary school teachers use motivational strategies specifically in respect of student academic assessment and performance. Six research studies were identified describing the behaviours secondary school teachers engaged in to improve student performance in assessment. Taken together, the studies presented show the importance of teacher behaviours to students' academic performance, with both positive and negative impacts. The review highlights a need for further research on teacher knowledge of the effects of teacher behaviour upon the motivation of students. The review recommends collaboration between teachers and students specific to the context of learning programmes that lead to high-stakes assessments, in order to provide a locally sensitive knowledge base for teachers' practice.
