The Open University has been providing open and flexible education to over 2 million students worldwide since 1969. In response to increasing demand for online learning, the university has been managing tutorials and events at scale using the Adobe Connect platform. Over the past years, the university trained over 4,500 staff and hosted over 40,000 online events annually with up to 5,500 concurrent users. During the COVID-19 pandemic, the use of online rooms tripled to support remote learning and community building. Key considerations for managing online tutorials at scale include ensuring users have proper technical setups, providing training, and adapting delivery methods for different types of virtual events.
