Educational reform centres on changing teacher behaviour, as it is teachers who filter through the curriculum to learners. Educational reform could therefore be viewed as reforming or changing teacher behaviour. This article investigates some of the factors influencing teachers' behaviour namely knowledge, attitude and views and beliefs. The complexity of research on teaching and teacher education is addressed by focusing on the elements of three factors as well as the relationship between these influencing factors. A research framework on teacher behaviour is presented, in an effort to expand the theoretical understanding of the factors influencing teacher behaviour and to guide future teacher education.
