"I think our whole field of educational research in South Africa is relatively young. There is so much we need to know more about, and from the empirical base of our schools, classrooms and learners. I think the transition years from primary into secondary mathematics what teachers need to know and do to teach across subjects at that level are very poorly understood. This is critical in mathematics where the move to greater abstraction and working with symbolic forms emerges. It is also a critical point where we need to know more about what it means to learn and teach mathematics in a dominant minority but extremely powerful language (English)."
