Abstract: The integrated construction of ideological and political courses across secondary vocational, higher vocational, and undergraduate vocational education represents a refined and advanced extension of the integrated development in primary, secondary, and tertiary education. It serves to facilitate the synergy between the ideological and political education system and the talent cultivation system within vocational education. However, constrained by the inertial barriers of disjointed articulation between different stages of vocational education, the integrated development of secondary-higher-undergraduate vocational ideological and political courses is beset by multiple challenges: the overall weakness and insufficient inter-stage communication of teaching faculty; the misalignment between the consistent overarching course objectives and the disordered vertical articulation of curriculum content; the structural imbalance and limited sharing of teaching resources; and the laggardness of teaching methodologies coupled with a lack of stage-specific characteristics. To address these issues, a systematic and collaborative mindset should be adopted, with targeted efforts directed at ecological system construction, dynamic incentive activation, institutional mechanism standardization, and educational effect extension, thereby breaking through the bottlenecks in the integrated advancement of secondary-higher-undergraduate vocational ideological and political courses.
