This research focuses on the construction of digital courses for older adults education, aiming to address the “digital divide” and promote high-quality development in older adults education. It analyzes the current status, identifying challenges such as homogeneous course design, insufficient specialized resources, and lagging support systems. The study proposes key construction contents, including a multi-dimensional service system, integration of online-offline learning, integration of information technology, and strengthened digital learning guidance. Optimization paths are suggested, such as improving the “content + technology + service” framework, enhancing platform construction, establishing evaluation-driven management, and boosting teachers’ digital capabilities. The research highlights the importance of user-centered design and interdisciplinary collaboration to create inclusive, intelligent digital education ecosystems for older adults, facilitating their integration into the digital society and lifelong learning.
