Initial teacher education programmes such as the Postgraduate Certificate in Education (PGCE) in South Africa are undergoing significant changes with the introduction of a new policy regime. This paper briefly outlines the policy changes advanced for teacher education programmes in South Africa. It examines productive pedagogies as a conceptual framework to underpin such a restructured programme. It then proposes that multiple representations can serve as a productive pedagogy of enactment in the science classroom because it engages the student with higher-order thinking skills, connects them with the world beyond the classroom in a supportive environment, and values difference by affording students multiple opportunities to develop a deep understanding of concepts. Some examples are given and the broader implications for classroom practice are discussed.
