Open peer commentary on the article “Examining the Role of Re-Presentation in Mathematical Problem Solving: An Application of Ernst von Glasersfeld’s Conceptual Analysis” by Victor V. Cifarelli & Volkan Sevim. Upshot: Cifarelli & Sevim outline the distinction between “representation” and “re-presentation” in von Glasersfeld’s thinking. After making this distinction, they identify how a student’s problem solving activity initially involved recognition, then re-presentation, and finally reflective abstraction. I use my commentary about the Cifarelli & Sevim article to identify two ways they could extend their current line of research.
