Abstract
The construction of knowledge by students continues to be a central concern of mathematics education, and research has shown the importance of theoretical approaches for our understanding of construction of knowledge. Tommy Dreyfus has not only made substantial contributions to this field but has forged links between researchers in this area, and encouraged new researchers. This symposium provides an introduction to Tommy’s research for some MERGA members, a chance to reflect further on it for others, and opportunities for everyone to develop new insights by connecting ideas in these papers.
