We review literature relevant to using technology in the teaching/learning of mathematics to highlight four roles of effective technology use: (a) promoting cycles of proof; (b) presenting and connecting multiple representations; (c) supporting case-based reasoning; and (d) serving as a tutee. We then discuss how they intersect with good instruction. Finally, we provide specific examples to illustrate how these roles of technology can be used to maintain the focus of a technology course on mathematics.
