Abstract
Two major developments in mathematics curricula have been the 'New Maths' of the 1960s and
the recent changes of the 1990s. A framework developed by Howson (1979) is used to
compare and contrast these two periods of mathematics curriculum change. What are the
influences which shape curriculum development and to what extent are these changes under the
influence of anything or anyone? It is suggested that mathematics educators have made a
difference in curriculum development through placing constructivism on the curriculum
agenda, countering the effects of current reforms in education. From this comparison, further
research agendas are proposed.
