Engagement in scientific discourse is an essential part of becoming a scientist. In this exploratory study, we aim to examine the scientific discourse (and resulting benefits) between undergraduate biology students and professional scientists. We developed a novel method for engaging in scientific discourse, grounded in the theory of legitimate peripheral participation, where undergraduate biology students participate in communities of practice within their own departments. Students selected a piece of primary scientific literature (PSL) from a professional scientist in their department and, after spending time annotating the PSL, met with the professional scientist to engage in scientific discourse. We analyzed the time students spent speaking and characterized questions students ask professional scientists. In addition, student motivation for reading PSL and students' sense of belonging to their department shifted positively, suggesting that students are integrating into the scientific community of practice being formed between students and professional scientists. We discuss best practices for supporting effective scientific discourse between undergraduates and scientists.
