The Notation in Science Communication (NSC) provides students an opportunity to develop their abilities to effectively communicate technical information to varied audiences using multiple genres and modes. A total of 115 students have earned the NSC as of May 2023. Currently there are just over 100 students in the program, with between 40-50 new students admitted each year. The NSC is similar to a minor that culminates with the development of an ePortfolio capstone. In this article, we focus on the process of creating an NSC ePortfolio and on the scaffolding practices that we have integrated into our pedagogy. We analyze 44 student ePortfolios, feedback from student alumni, and an NSC student conference presentation. Three themes emerge: (a) student ePortfolios articulate an increased understanding of multiple identities, and students explore how these identities make them more effective science communicators; (b) students demonstrate evidence of growth and learning about science communication; and finally, (c) they share their capacity for using science communication to be engaged citizens in their local and global communities. We argue that students graduate from our program with both a deeper understanding of the importance of science communication in responding to the pressing issues facing our world today, and also with a fundamental recognition of their place in the world as effective science communicators.
