Issues in modelling terms involving subtraction in a manipulative environment for linear equations—and a possible solution
Résumé
In this paper, we present and utilize theories about interface design and didactical models to evaluate how existing manipulatives models for linear equations represent terms involving subtraction. We then outline a redesign of subtraction zones for algebra tiles that can be implemented on a screen. The presented work is intended to serve as an example case for theory-guided design of digital or digitally enhanced didactical models, anticipating the all-important learning activities with the resulting models.
