本研究旨在探究手机依赖对大一新生学习投入的影响机制,聚焦江西省某理工科高校,通过实证分析揭示其内在关联与干预路径。研究发现:大一新生手机使用时间与学习投入呈显著负向影响,使用时间越长,学习投入越低,且学生自我约束力有待加强;课程成绩与学习投入也呈显著负向影响,提高学生时间管理和明确学习动机是提升学习投入水平的关键。基于大一新生在转型过渡期的特殊脆弱性,提出“技术赋能 + 人文关怀”协同干预策略,如智能管理工具引入、课程开发及任务驱动型课堂模式重构,以提升时间管理与学习动机。研究为高校破解手机依赖困境、优化新生适应性教育提供实证依据,助力高等教育高质量发展。This study aims to explore the influence mechanism of mobile phone dependence on the learning engagement of freshmen in a certain science and engineering university in Jiangxi Province. Through empirical analysis, it reveals the internal connection and intervention paths. The research finds that the time freshmen spend on mobile phones has a significant negative impact on their learning engagement. The longer the usage time, the lower the learning engagement, and the self-discipline of students needs to be strengthened. Course grades also have a significant negative impact on learning engagement. Improving students’ time management and clarifying their learning motivation are the keys to enhancing the level of learning engagement. Considering the special vulnerability of freshmen during the transitional period, a collaborative intervention strategy of “technology empowerment + humanistic care” is proposed, such as the introduction of intelligent terminal management tools, the development of “University Learning Methods” courses, and the reconstruction of task-driven classroom models, to enhance time management and learning motivation. The research provides empirical evidence for universities to solve the p
