ab: Summary: In this chapter I discuss studentsâ€™ difficulties in algebra,
considering in particular those students affected by developmental
dyscalculia (DD). Focusing on algebraic notions such as unknown,
variable, algebraic expression, equation and solution of an equation, I
will describe possible processes of meaning making in students with low
achievement in mathematics, or even diagnosed with DD including adult
learners. This involves considering algebra not only in its syntactic
aspects but also in its semantic ones. The assumption on which the work
is based, is that some difficulties in learning algebra could be due to
the lack of meaning attributed by the students to the algebraic
notions. Basing the analyses on studies both in the domain of cognitive
psychology and in the domain of mathematics education, I will show how
students with DD can make sense of the algebraic notions considered
above, thanks to tasks designed within AlNuSet exploiting its semiotic
multi-representations based on visual, non-verbal and
kinaesthetic-tactile systems. AlNuSet (Algebra of Numerical Sets) is a
digital artifact for dynamic algebra, designed for students of lower
and upper secondary school.
