Abstract
The assumption that mathematics is learnt by the individual construction of ideas,
processes and understanding rather than through the transmission of pre -formed
knowledge from teacher to student is now a commonly held belief among
mathematics educators. An essential feature of this view is that existing
conceptions, whether gained from everyday experiences or previous learning, guide
the understanding and interpretation of any new information or situation that is
met. As a result, there is often a resistance to adopt new forms of knowledge or to
give up or adapt previously successful thinking, and the intuitive conceptions of
children may appear very different to accepted mathematical practice. While much
of the early support for constructivism has come from observations of situations
where new knowledge has arisen from concrete situations, constructivism also
, needs to account for the more complex mathematics which has been formed by the
processes of abstraction and generalisation of earlier ideas. The conventions that
have emerged cannot simply be replaced by the idiosyncratic building of a host of
<" individual learners; they need to be acquired in the same social context from which
the mathematical concepts are to be drawn. This paper reports research which set
out to establish a constructivist approach to the learning of initial fraction ideas,
focussing on the social setting and activities which could lead to the negotiation
and reconciliation of mathematics formed from historically and culturally
determined generalisations.
