Our team developed flipped classroom, asynchronous information literacy tutorials for first-year students at the University of Arkansas to address challenges in delivering personalized instruction to high-enrollment courses. Collaborating with freshman program directors, we created tutorials embedded with assessments, collecting nearly 2,000 student responses. We also surveyed instructors to gauge the tutorials' impact on student learning. Our presentation will cover the entire process, from creation to deployment and evaluation, sharing insights on how assessment shaped the final product and what we learned about effective techniques for gathering feedback to improve future iterations of the tutorials.
