ab: This paper focuses on the introduction of the concept of limit at secondary
school level. Drawing on research on the role of metaphors, movement
and perception in the construction of mathematical concepts, we
developed an approach to the concept of limit which considers
perceptive elements as a starting point. The students are required to
construct and manipulate representations of functions in a graphic
calculator environment (namely, the TI89). The transition from the
register of graphical representations to the symbolic one takes place
in two ways: through the re-elaboration of the language used by the
students to describe their graphic manipulation of the functions and
through the introduction of symbols which will support the algebraic
manipulation to be done later on.
