Classroom Reform stands as a pivotal initiative for implementing the Action Plan for Enhancing Quality and Excellence in Vocational Education and deepening the “Three-Education Reform” (targeting teachers, teaching materials, and teaching methods). Using Fundamentals and Applications of Finance as a representative case, this study addresses prevailing pain points and systemic bottlenecks in specialized foundational course instruction. It proposes a “Five-in-One Integration, Three-Dimensional Drive, Six-Step Interaction” implementation pathway for Classroom Reform, providing actionable guidance for Higher Vocational Colleges to advance pedagogical transformation. Key innovations include:‌ Integrated curriculum-politics system:‌ A finance-oriented ideological and political education framework is holistically constructed through coordinated development of curriculum design, pedagogical models, resource development, assessment systems, and faculty capacity building, thereby fulfilling the fundamental mission of fostering virtue through education.‌ Three-dimensional content reconstruction:‌ Teaching content is restructured across work tasks, application scenarios, and learning outcomes dimensions, driving deep convergence of “industry requirements, curricular standards, skill competitions, and professional certifications” (Gang-Ke-Sai-Zheng).‌ Interactive pedagogical architecture:‌ A six-step interactive teaching cycle (“Clarify, Analyze, Explore, Practice, Evaluate, Extend”) is implemented, establishing a closed-loop smart classroom ecosystem featuring pre-class intelligent diagnostics, in-class interactive engagement, and post-course digital competency profiling. This comprehensive approach reconstructs a dynamic educational ecology, demonstrating a replicable model for vocational education reform.
