Annenberg Learner's mission is to "Advance Excellent Teaching in American Schools." We have pursued this mission for more than three decades by funding and distributing multimedia resources for teachers (K-12 and college levels) to teach their subjects and to stay up-to-date in their fields. As our name Annenberg Learner implies, we focus on the teacher as a learner, as well as the student as a learner. In fact, all adults who are lifelong learners have enjoyed and benefited from using our resources...."
