Abstract
Student transition from arithmetic to algebraic reasoning has been acknowledged as an essential but problematical process. Previous research has highlighted the difficulties in shifting students towards relational thinking when solving equivalence problems. This paper reports on an investigation into students? use of relational thinking to solve equivalence problems after they have been in classrooms where specific focus has been on developing
flexible, efficient computational strategies. The results reveal that most students used computational strategies to solve the equivalence problems rather than relational strategies. Many of the common errors, students made reflected a lack of understanding of the equal sign.
