Understanding Geometry for a Changing World, 71st Yearbook (2009)
By Timothy Craine, Rheta Rubenstein
Geometry is currently enjoying a revival, partly as a result of the emergence of interactive geometry software. Articles in this yearbook examine expanding visions of geometry, the latest thinking about the development of students' geometric learning, and new perspectives on effective practices for teaching geometry in elementary through high school. The yearbook includes a CD with lessons, activity sheets, application files, video clips, and Web links.
