Conceptual change is the creation and modification of concepts through
development and experience, resulting in new concepts that are often
qualitatively very different.  The topic is being studied from a variety
of perspectives.  Cognitive development has been concerned with the
nature of children's concepts, how they differ from adult concepts, and
how the former develop into the latter.  Research in scientific
conceptual change has investigated how new conceptual structures in a
scientific community come to replace existing ones through scientific
revolutions or through long-term scientific enterprise.  Research in
education has been concerned with the nature of students' concepts and
misunderstandings and their development through learning processes in
and out of the classroom.  Artificial intelligence researchers have
created computational models of conceptual and representational change.

This special issue will bring together a diverse set of approaches to
the common fundamental problems of conceptual change: what it is, how it
occurs, and how to facilitate it.  Papers on all aspects of conceptual
change are invited.  Discussion of psychological, philosophical,
educational, and computational studies of conceptual change are
appropriate; of particular interest are the implications of the results
of such studies towards understanding the fundamental nature of
conceptual change.
