The National Council of Teachers of Mathematics identified technology as a feature of high-quality mathematics education. The purposes of this study are to: (1) observe and describe how pre-service mathematics teachers subsequently incorporated technology-generated representations into
their student teaching; and (2) understand and expound on their rationales for using such representations. The authors found that these pre-service teachers appropriately utilized the provided technology to generate representations for the purpose of helping their pupils to develop conceptual understanding and reasoning.
