LERMAN, S., 2010. Theories of mathematics education: is plurality a problem? Theories of Mathematics Education: Is Plurality a Problem? New York: Springer-Verlag Berlin Heidelberg, pp.99-109.
In this chapter I examine empirically the diversity of theories in our field, based on a detailed study carried out recently, and I draw on the sociological theories of Basil
Bernstein to relate the developments to the nature of intellectual communities and
their productions. In particular, I suggest that the multiplicity and divergence are not
surprising nor are they necessarily damaging to the field. I end by discussing
concerns about accountability in relation to research in education.
