Reflection Guides 
Guidelines for Professional Development Using Publications

NCTM school journals and other publications are a rich resource for professional development. Reflection Guides are written by members of NCTM's Professional Development Services Committee (PDSC).

Featured Reflection Guide - Representation 

Paper Moon: Simulating a Total Solar Eclipse 

Reflect on practice by exploring:

  • How multiple representations can be used to enhance student learning and understanding of student learning
  • How physical, tabular, graphical, verbal, and symbolic representations can be connected in a lesson
  • Connections across the different strands of the curriculum—algebra, geometry, and trigonometry
  • Connections among different subject areas—mathematics, astronomy, and science
  • Use of spreadsheets/technology to analyze data
  • Appropriate use of concrete models to explore mathematical ideas
  • How instruction can incorporate student interactions and feedback
