I first promoted the use of Internet-based listservs within classes in 1994. I have subsequently promoted wikipedia, blogs, facebook, youtube and whatever tools can assist in preparing students for future careers.
I have taught hundreds of professional workshops on risk analysis beginning in 1994 in Guelph, and 1996 at the IAMFES conference in Seattle (International Association for Milk, Food and Environmental Sanitarians, the predecessor organization to the International Association for Food Protection, IAFP).
Through bites.ksu.edu and barfblog.com, I provide research, educational and journalistic opportunities for secondary, undergraduate and graduate students in a multi-media electronic environment. As such, I have a number of students constantly moving through the lab from a variety of backgrounds – food science, nutrition, psychology, sociology, journalism, etc.
I have recently begun to further emphasize and explore the role of electronic-mediated distance education and instruction. Although I gave my first video presentation to IAFP in Atlanta in 2000 as my Ivan Parkin award lecture, I am now using pre-recorded and live video to deliver interactive instructional material to public health professionals, elementary and secondary teachers, and to food safety professionals around the world. My laboratory is operated on this basis, so I can provide advising and collaboration with students and colleagues throughout Kansas and throughout the world.
K-State media relations provided a brief, Jun, 2010, summary of such activities, available at http://www.k-state.edu/media/k-statement/vol32/60910powell.html, and summarized below.
Powell has broadcasted more than 20 keynote speeches and presentations via programs such as Skype and iChat since 2000. Using a combination of live video feeds and pre-recorded video, Powell has presented on various food safety topics to audiences ranging in size from five to 800 people. “I actually find it forces me to be more creative,” he said. “If you’re giving a talk in person, you can tell when people are sort of zoning out or falling asleep and you can modify it. You don’t get that on video because you’re talking to a camera.”
I have also extensively used food safety blogs, infosheets and other new media tools in food safety extension, research and education, and am using graduate students to critically evaluate effectiveness.
