The COVID-19 pandemic led to a marked increase in the number of online courses in adult education. However, such courses are viewed ambivalently because, on one hand, they are associated with digitalisation processes and an increased accessibility, reach, and flexibility of learning opportunities, whereas, on the other hand, there are concerns about acceptance issues and participation barriers. Given this context, the present study examines whether new online courses for adults have supplemented or replaced existing on-site courses by conducting a program analysis of online courses at public adult education centres (Volkshochschulen, VHS) in Germany. VHS are the largest providers of adult education in the country. A comparison of programs from the years 2018, 2019 (pre-pandemic), and 2024 (post-pandemic) shows that most online courses supplement the existing program, and that the content of approximately every second online course can also be learned on-site at the educational centre. In contrast, 29 per cent of online courses have replaced an earlier on-site course. Hybrid courses, which enable both online and offline learning, are rare. Results are discussed along with their implications for adult education centres and adult learners.
