The teaching of mathematics in Australian schools has received considerable attention over the past decade. States and territories have designed and implemented new mathematics syllabi, and education sectors have supported teachers through sustained professional learning initiatives. Whereas the major focus of these initiatives has been on students constructing mathematical knowledge from a range of learning activities and quality instruction, the education of students with difficulties in learning mathematics has been given little direct attention. This analysis of current syllabus developments and professional learning initiatives highlights the risk of exposing students with learning difficulties to fragile program designs and classroom instruction. The research literature is also examined to propose ways in which these fragilities can be addressed.
