In the era of new engineering, data literacy has become an indispensable novel skill for people to participate in social activities as well as to improve their lives. As a critical way to cultivate data literacy of undergraduates in the big data era, data literacy education has attracted attention from the government, universities, and social enterprises, and has become an important part of training in higher education. Recently, the courses, projects and achievements of data literacy education in China are increasing, but they are still relatively weak. This paper, from the perspective of data literacy education theory, explores the current situation of data literacy education of undergraduates and its challenges, proposes a general strategy framework for undergraduate data literacy education, namely AAARS-ECFDA, and conducts experiments as well as corresponding implementation mechanisms, so as to provide a new way for domestic data literacy education on undergraduates.
