"WatchKnowLearn has indexed over 33,000+ educational videos, placing them
into a directory of over 3,000 categories. The videos are available without any
registration or fees to teachers in the classroom and to students at home 24/7.
Users can dive into our innovative directory or search for videos by subject and
age level. Video titles, descriptions, age level information, and ratings are
all edited for usefulness. Our Web site invites broad participation in a new
kind of wiki system, guided by teachers. We have had a tremendously positive
response from educators to the website. If we continue to work together, we can
create an incredible, free, educational resource for students across the
world." - taken fro
