Natural Editing of Algebraic Expressions
Abstract:
We call “natural editing of algebraic expressions” the editing of
algebraic expressions in their natural representation, the one that is
used on paper and blackboard. This is an issue we have investigated in
the Aplusix project, a project which develops a system aiming at
helping students to learn algebra. The paper summarises first the
Aplusix project. Second it presents a notion of algebraic expressions,
of representations of algebraic expressions. The last section develops
ideas about natural editing of algebraic expressions (insertion,
deletion, selection, cut, copy, paste, drag and drop) and presents the
choices made in the Aplusix system.
