Originally designed for K-12 teachers, the Understanding Evolution (UE) Web site ("www.understandingevolution.org") is a one-stop shop for all of a teacher's evolution education needs, with lesson plans, teaching tips, lists of common evolution misconceptions, and much more. However, during the past five years, the UE project team learned that another group of educators uses it, too. With additional funding from the National Science Foundation, the UE project team sent out a call for applicants to form a Teacher Advisory Board (TAB) that would help expand the UE Web site for undergraduate educators. After a year of hard work, the team unveiled an expanded and enhanced UE Web site in early 2011. Faculty can find a wide variety of teaching materials for many types of undergraduate settings and audiences. Visitors can now post a review, rate resources, connect content within the site, and access new guides and teaching tips for using original UE materials in the classroom.
