A MAJOR GOAL of graduate education is the development of students as "stewards of the discipline," scholars who can create and preserve knowledge and responsibly translate it through writing, teaching, and practical applications (5). These qualities are consistent with the American Physiological Society's list of professional skills for physiologists and trainees (3). Key competencies on this list include building core biomedical knowledge, research/analytical abilities, and communication skills. By default, core knowledge and research aptitude are a central focus of most graduate physiology programs. As a result, there is significant interest in teaching strategies like active and problem-based learning (PBL) that enhance the development of these competencies (9, 14). However, communication skills often receive less emphasis, leaving many graduate students underequipped to effectively share their knowledge with the wider community (7, 13). Most opportunities graduate students do have to learn and practice communication skills involve scientific audiences. However, for most students, effective public communication skills may be just as important (7, 13). Students planning to pursue academic careers, for example, will be expected to contribute to the research missions of their institutions, most of which emphasize the dissemination of scientific knowledge for the good of society. Indeed, public outreach is often a key component of institutional service expectations. This requires scientists to clearly and succinctly explain complex ideas to nonexpert audiences. Successful scientists also need these skills to effectively explain their work to peers in other disciplines (e.g., as guest lecturers in other departments) or staff officials at the National Institutes of Health or other health/ research organizations, and to describe the importance of their research to nonexperts in industry, foundations, and potential donor/philanthropic groups to obtain funding. Similarly, and perhaps even more importantly, a significant percentage of graduate students studying physiology are bound for nonresearch careers in health care, public health, teaching, industry, and other fields. Without a doubt, these students will need to clearly and effectively explain science to patients, students, colleagues, and other nonscientific groups. Nevertheless, most graduate students receive little or no training in communicating with such general audiences. A general lack of training in public communication skills is a particular concern in the context of key public health problems, pressing issues that require research attention and broader public action (2). One such issue is population aging.
