Analogies offer conceptual models for supporting the development of un
derstanding. Contrary to some expectations, there is growing evidence
that young children can reason analogically. Much of this evidence com
es from experiments intended to test psychological theories. This stud
y aimed to gauge the practical potential of analogy in topics often co
nsidered by teachers difficult for young children to understand. Aspec
ts of young children's understanding of current electricity were compa
red in two conditions, namely with and without an analogy (87 and 89 c
hildren, respectively; 6-7 years of age). The results indicated that t
he analogy was of practical value in teaching for understanding. It is
suggested that their bases be carefully prepared prior to teaching th
e target topic and that what is to be understood is modelled directly
and is explicitly related to its equivalent in the topic. Further inve
stigations to determine conditions for the effective use of analogies
when teaching young children, who benefits particularly and in what wa
ys seem warranted.
