5 pages, Professionals, such as Extension personnel, who communicate with a range of non-specialists about scientific or technical information face particular challenges. A common goal of all such professionals is to effect at least some change in their audiences' understanding and perhaps in their actions. A key challenge for many of these professionals is a lack of familiarity with research relating to communicating and making decisions about scientific and technical topics. Public Science Communication Research and Practice, a series of publications from Oregon State University, is designed to identify, distill, and highlight useful social science research to help professionals communicate more effectively.
