Librarians in the UC Davis Library’s Student Services Department dedicate a significant portion of their work to classroom-based information literacy and research instruction. Because of the limited face-time and interaction allowed in the one-shot instruction format, it is crucial to assess our instruction's content and efficacy to ensure we support student learning without placing an undue burden on undergraduates through overly complicated assessment mechanisms. This presentation will outline the development of departmental assessment tools for information literacy research instruction and how those tools were updated to streamline student input and librarian assessment processes. We will also share how the initial coding of student feedback illuminated key areas of impact in library instruction, resulting in the creation of supplemental instructional materials that directly address student needs while freeing the librarian’s time to teach more in-depth research instruction.
