The concept of “critical science literacy” advanced by Susanna Priest is significant to how citizens approach scientific knowledge, but the concept is also relevant to undergraduate students majoring in the sciences, who are not necessarily becoming “critically literate” in their own disciplines. That is, future scientists are not learning how arguments are structured, meaning is made, and facts are agreed upon—specifically through communicative practices—both within and outside of the scientific community. This gap in the curriculum can be addressed through collaborative (...) efforts between rhetoricians and sociologists of science. Drawing from three major disciplinary traditions—writing studies, the rhetoric of science, and science communication—this article posits that a pedagogical intervention is necessary to improve science communication with nonexpert publics. A science writing and communication course that is grounded in the rhetoric of science and that also has sociological, philosophical, and historical components can provide science students with a critical awareness of how their discipline operates in society and teach them how to become more responsible and effective communicators.
