In an article in Science and Public Policy, LSC alumni Pete Ladwig (M.S., ’11) and Kajsa E. Dalrymple (Ph.D., ’11), now assistant professor in the School of Journalism and Mass Communication at the University of Iowa, along with LSC faculty members Dominique Brossard and Dietram A. Scheufele, as well as Elizabeth A. Corley, of the Center of Nanotechnology and Society and the School of Public Affairs at Arizona State University, compare operationalizations of scientific understanding.
Using data from the 2007 Public Awareness of Nanotechnology Study, this research compares the concepts of “factual knowledge” and “perceived familiarity,” two commonly used measures to test for scientific understanding. The authors argue that the concepts are distinct and are predicted by different variables. They conclude, “Our analyses show that mass media messages continue to inﬂuence individuals’ underlying knowledge processes differently, which may subsequently inﬂuence levels of science understanding. Speciﬁcally, this study highlights the importance of the internet in disseminating information about nanotechnology and science.”
