Variables in Mathematics Education

2011
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 ...

Constrained mathematics analysis of uncertain variables

SMC'98 Conference Proceedings. 1998 IEEE International Conference on Systems, Man, and Cybernetics (Cat. No.98CH36218), 2002
Analyses (e.g., safety analyses and reliability analyses) that are based on variable or uncertain inputs need to reflect the ranges of potential output variability or uncertainty. A challenging problem in mathematically processing the operands is that constraints inherent in the problem definition can require computations that are difficult to ...

On Problems in Mathematical Physics with Variable Parameter

Journal of Mathematical Sciences, 2017
Summary: We consider evolution equations with variable parameters. We obtain new representations of solutions and indicate their applications to inverse problems in mathematical physics.

A Mathematical Type for Physical Variables

2008
In identifying the requirements of a markup language for describing the mathematical semantics of physics-based models, we pose the question: "Is there a mathematical type for physical variables?" While this question has no a priori answer, since physics is fundamentally empirical, it appears that a large body of physics may be described with a single ...

Variables in Elementary Mathematics Education

The Elementary School Journal, 2016
AbstractIn this article, I analyze episodes from two third-grade classrooms drawn from a larger classroom teaching experiment to explore how these students began to incorporate nonnumerical symbols in their mathematical expressions when asked to represent indeterminate quantities.
