Abstract
Observations of 104 lessons taught by final-year secondary mathematics student teachers were analysed to identify weaknesses in their pedagogical knowledge. 11 content Pedagogical mathematics weaknesses" were found in the areas of meaning and purpose, accuracy appropriateness, quality and of explanation and quality of language. Six mathematics "pedagogical themes" were identified as in need of particular attention. It is argued that teacher education programs need to include more explicit discussion of the purpose, basic concepts, and pupil learning of such central mathematical themes.
