The Physiology Educational Research Consortium (PERC) is a collaborative research and development effort among 13 physiologists and physiology educators representing 12 post-secondary institutions, ranging from community colleges to medical schools. PERC develops materials and techniques that can help students build "better mental models of physiological systems" and, in order to create more productive learning environments, educates teachers on how to incorporate these techniques into a classroom setting. The site offers research papers, abstracts, workshop and course information, and network support for those needing ideas on how to approach a topic or set of topics in physiology.
