With the increase in data being produced and made available to researchers and the general public, there is a growing need to build awareness about how to evaluate and work with data in the context of an evolving and more diverse workplace. As a part of this shift, employers often expect new graduates to have skills in data literacy and data analytics. However, classroom instruction often focuses on specific tools and methods rather than on general data literacy skills, such as how to critically evaluate and interpret data. While the latter set of skills can be gained through involvement in research projects, many students (particularly undergraduate students) do not conduct research during their academic career. This presents a unique opportunity for academic libraries to fill in the gap via data literacy instruction and data services for undergraduate students. This presentation will describe the creation of a data fellowship program for STEM undergraduate students at Florida State University (FSU). The program provides undergraduate "data fellows" at FSU with the opportunity to teach, collaborate, and engage in open conversations with their peers and library colleagues on projects related to data literacy, data science, data ethics, and open data. These opportunities position the fellows to serve as advocates for critical data literacy on campus and provide them with skills that position them for post-graduation success. Current projects and initiatives will be discussed, along with insights and perspectives from the initial phases of the program. The presentation will conclude with a brief overview of future plans and goals.
