Addressing issues such as outdated curricula, disconnection of practical training, and static evaluation systems in traditional teaching models, this study constructs a “Three-Stage Four-Dimension” project-based curriculum reform model centered on industry-education integration. The model integrates a progressive competency development path (“foundational cognition - specialized breakthrough - comprehensive innovation”) with four-dimensional objectives (disciplinary knowledge, engineering practice, innovative thinking, and professional literacy), forming a closed-loop collaborative system between academia and industry. Empirical data demonstrate that post-reform improvements include a great increase in students’ ability to solve complex engineering problems. The study identifies common challenges such as uneven resource coordination and interdisciplinary integration barriers, proposing optimization strategies like regional industry-education alliances and digital twin platforms. This research provides a theoretically grounded and practically validated paradigm for engineering education reform in the new energy sector.展开更多
