Abstract
Analogy appears to be one of the most important mechanisms underlying human thought, at
least from the age of about one year. A powerful way of understanding something new is by
analogy with something which is known. The research community has given considerable attention
to analogical reasoning in the learning of science and in general problem solving, particularly as it
enhances transfer of knowledge structures. Little work, however, has been directed towards its role
in children's learning of basic mathematical ideas. This paper examines analogy as a general model
of reasoning and proposes a number of principles for learning by analogy. Examples of analogical
reasoning in children's mathematical learning are presented, including children's ability to recognize
similarity in problem structure which was investigated in.a recent two-year study. The proposed
principles are applied to a critical review of some commonly used concrete analogs and to a brief
analysis of more abstract analogs, namely, established mental models which serve as the source for
the construction of new mathematical ideas.
