The field of educational technology evolves rapidly, increasing in complexity and sophistication; educators struggle to keep up to date.

This innovative system is an "open educational resource" for professional development. [For the complete volume, "Educational Media and Technology Yearbook, Volume 36, 2011," see ED597737.]
