Units Construction and Coordination: Past, Present, and Future.

Boyce, Steven; MacDonald, Beth Loveday; Hackenberg, Amy J.

This document titled "Units Construction and Coordination: Past, Present, and Future" provides an in-depth exploration of the concept of units construction and coordination in mathematics learning. It discusses the historical contributions of Jean Piaget and Ernst von Glasersfeld to the field and emphasizes the importance of units construction and coordination in understanding mathematical reasoning. The document offers various interpretations of units coordination, including place value operations and relationships between measurement units. It also examines the stages of units coordination and its relationship to other mathematical concepts such as fractions and algebra. The document includes summaries of five articles that further investigate units coordination in different contexts, such as algebraic reasoning, fractions knowledge, and teacher education. Overall, this document provides valuable insights into the complex nature of units construction and coordination in mathematics education.
