Abstract

This study looked at how a group of South African secondary school mathematics teachers regarded the concept of gradient (slope). Results are reported from nine free-response items on a paper-and-pencil test administered to practising teachers who were pursuing qualifications to teach Grades 10-12 mathematics through an Advanced Certificate in Education (ACE) programme. The findings suggest that teachers' understanding of gradient varies greatly. A number of teachers in the study demonstrated very little to no understanding of this important concept, whilst others demonstrated a strong understanding of gradient and were able to conceptualise it in many different ways. Implications for teacher professional development are considered.
