This study investigates the impact of rebranding office hours to "happy hours" on student engagement at Florida International University, where class sizes often exceed 100 students and can be as large as 400. The initiative aimed to address the challenge of low student attendance during traditional office hours, a critical time for student-professor interaction. Implemented in summer 2021 during COVID-19, "happy hours" were held in lab spaces to allow for social distancing and create a more inviting atmosphere. A focus group of 36 students across four semesters provided feedback, revealing increased attendance and positive perceptions. Students appreciated the informal and welcoming environment, which reduced intimidation and fostered a sense of community. The study highlights that "happy hours" promoted not only academic support but also peer connections, enhancing the overall learning experience. This flexible approach improved student participation and academic performance, emphasizing the importance of an inclusive and supportive educational environment.
