An analysis of visual representations of linear algebraic expressions constructed by selected Grade 9 learners: a case study in an after-school mathematics club.



This study has the following aims:

  • to describe learners' visual representations of algebra;
  • to develop a taxonomy with which to describe these representations and the understanding they represent;
  • to analyse whether and to what extent learners' visual representations developed over the period of study.
  • to loosely determine the extent to which development in learners' visual representations indicated a development in their understanding (that is, their objectification) of the underlying mathematical relationships with which they were working.



Research questions

  • How can participants' visual representations of algebra be classified in a way that preserves the understanding behind the representations?
  • In what ways did these representations develop over the course of the club?
