This paper explores the needs to enhance digital literacy and skills among university students in the digital age. It centers on the concept of quality control in process management and designs a Double Helix Structure model for improving the quality of digital literacy education. On the teaching content side, it enriches and enhances the quality through selection, supervision, and evaluation. On the student learning side, it encourages students to enhance their self-awareness, independent planning, and personalized learning by holding annual digital literacy competitions, thereby addressing personal shortcomings and achieving continuous improvement. The model has been piloted at multiple universities, yielding significant results in areas such as teaching awards, online courses, teaching materials, question banks, and certifications.
