Abstract
This paper is in three parts. In the first part, I compare and contrast three typical methods of
teaching generalisations in mathematics. In the second, I describe the theory of generalisation
expounded by the Soviet psychologist Vasily Davidov. In the third part, I re-examine the
three methods of teaching mathematical generalisations in the light of Davidov's theory, and
make some general conclusions.
