Older adults are underrepresented in computing education; broadening participation in computing has remain predominantly at K-12 and college settings. Yet, the population of older adults is increasing across many regions. Strategies for broadening participation in computing education for adult learners have been under-explored. This poster reports our effort towards broadening participation in computing for adult learners by exploring how computational thinking problem-oriented unplugged activities might help to gently introduce older adults into computing education. Being an exploratory study, data was collected using mixed method approach. This report presents preliminary findings that suggest the potential benefits of computing education for older adults, including social collaboration and demonstration of computational thinking practices that could help them to remain active while aging. Moreover, future research direction in this regard is also discussed.
