Session Summary

Learning Trajectories as Boundary Objects for Psychometricians, Learning Scientists, and Practitioners in Mathematics Education

Mon, April 20, 12:25 to 1:55pm, Virtual Room

Session Type: Symposium

Abstract

The development, validation, and use of learning trajectories or progressions have become the focus of systematic research efforts in mathematics education in recent years as educational researchers, curriculum designers and practitioners grapple with the challenge of aligning constructivist instruction with curriculum and assessment. The characterization of learning trajectories as boundary objects reflects both the challenges and potential of working at scale over extended periods of time through the multiple lenses of learning scientists, psychometricians and practitioners. This symposium will draw on four significant bodies of work in this field to consider issues arising in defining, building, and validating learning trajectories, their evolution over time, and their use in practice.
