Grandparent University is a three-day experience for OSU alumni and their grandchildren to experience "college life" by living in a residence hall, choosing a "major," and attending "classes" and social events. In summer 2023, the OSU Libraries hosted a major, "Exploring the Modern Academic Library." As part of the major, a graduate student in Learning Design and Technology and former K-12 teacher teamed up with a librarian to present a session on information literacy. They faced the challenge of having to teach multiple demographics at the same time: grandparents, who ages varied widely, and grandchildren ages 10-13. This presentation will share how the session was designed and taught, as well as lessons learned through the experience.
