ab: Summary: This paper suggests that consistently referring to variables as
placeholders is an effective countermeasure for addressing a number of
the difficulties students’ encounter in learning mathematics. The
suggestion is supported by examples discussing ways in which variables
are used to express unknown quantities, define functions and express
other universal statements, and serve as generic elements in
mathematical discourse. In addition, making greater use of the term
“dummy variable” and phrasing statements both with and without
variables may help students avoid mistakes that result from
misinterpreting the scope of a bound variable.
