Abstract: Although most children in the US are vaccinated against potentially deadly diseases, such as polio, measles, and tetanus, many adults dismiss the usefulness of vaccines, or simply don't bother to get vaccinated. What are the beliefs that influence these important decisions? What do people believe about how viruses work? To investigate this issue, we surveyed 8th and 10th grade students, and conducted in-depth interviews with a smaller group of students and teachers. The questions included, (a) what is a virus?, (b) how do viruses infect living things?, (c) how does the body respond to infection?, and (d) how can viruses be prevented and treated? The survey and interview data was used to identify several distinct mental models of how viruses work. We will report findings on how students' and teachers' mental models are similar and different, how they compare to an expert model, and what sorts of misconceptions are held.
