edited multimedia resources and lesson plans, most of which are derived from
WGBH broadcast programming such as Evolution, NOVA, A Science Odyssey,
Frontline, American Experience, ZOOM, and Building Big, and some of which
have been produced in response to demand from teachers exclusively for the Teachers' Domain library. The first phase of the site development focused on the Life Sciences with subsequent phases turning to the creation of additional resource areas, both in the sciences as well as other disciplines. WGBH commissioned the Center for Children and Technology (CCT) to study its online service, and the findings from the study are available at the Mirror URL.
