This study uses a combination of empirical analysis to conduct a comprehensive analysis of the role of digital media and student management in higher vocational colleges. The results show that the current application status of digital media in student management shows extensive and profound impact. With the rapid development of information technology, digital media has become an important tool for student management in higher vocational colleges, covering many aspects such as course management, attendance management, and student information inquiry, greatly improving management efficiency and convenience. By establishing a digital system, the school has achieved comprehensive coverage of student information management and online education. At the same time, digital media also plays an important role in students' social interaction and has become an indispensable part of students' daily lives. However, digital media applications also bring some problems. Information overload and distraction can make it difficult for students to focus, while security risks threaten student privacy. Solving these problems requires schools to take effective measures, such as improving information literacy and security awareness, and establishing a complete information security system. The impact of digital media on student development is complex and diverse. Its advantage lies in providing a broad learning space and diversified learning methods to promote students' communication and socialization. However, negative effects such as information overload and Internet addiction cannot be ignored. In order to better guide students to use digital media, schools and families need to strengthen digital media literacy education, pay attention to students' mental health, and strengthen network security. In student management, the advantages of digital media are mainly reflected in improving efficiency and interactivity, and promoting management innovation and development. However, the popularization of digital media needs to face issues such as technical and device support, security and privacy protection. By strengthening measures such as construction, training, supervision and management, schools can better leverage the advantages of digital media and improve management efficiency and service quality. Going forward, digital media will play an even more important role in student management. Intelligent management, expanding management fields and promoting student self-management will be the direction of future development. However, the security and popularity of digital media remain challenges that need to be addressed. By strengthening comprehensive measures such as construction, training, supervision and management, schools can better guide the future development of digital media in student management, provide students with more intelligent, personalized and efficient services, and promote their all-round development.
