The American Physiological Society (APS) Archive of Teaching Resources is a digital library of peer-reviewed science teaching resources that contains over 2,200 lesson plans, teaching journal articles, and audiovisual materials. A range of learned societies contribute materials to the archive, including the APS itself and the International Union of Physiological Societies. On the homepage, visitors can click on the Featured area for a nice introduction to some of the most popular materials on the site. Here they can look over the Top 100 resources for use with K-12 students, undergrads, graduate students, and those in continuing education. Moving along, the Research Bytes area contains links to recent news items that cover everything from brain fatigue to exercise strategies that successfully combat Type 2 diabetes. Visitors are encouraged to sign up for their own account on the site, which will allow them to save and categorize resources for their own use.
