     DYNAMIC MATHEMATICS VISUALIZATION FOR YOUNG LEARNERS
                    Sketchpad in Grades 3-8

         http://www.kcptech.com/dgylconf/proceedings/

  Researchers, curriculum developers, and educators have begun
  creating a curriculum and software structure around
  Geometer's Sketchpad technology in support of dynamic
  geometry visualization for all young learners.

  From a working conference, held at the University of
  Illinois at Chicago in February, 2003:

    - presentation summaries or abstracts
    - GSP sketches
    - Powerpoint presentations
    - other contributed material relating to each presentation
