大中小学思政课一体化建设是落实立德树人根本任务的必然要求。当前，大中小学思政课一体化教学仍存在学段衔接不畅、教学内容层次失配、教学方式与学生认知发展不相适应、协同机制不健全等问题。针对上述困境，以唯物辩证法为方法论指导，大中小学思政课一体化并非不同学段课程内容的简单叠加，而是立德树人共同目标统摄下，不同学段教育要素遵循学生成长规律，通过矛盾运动实现纵向贯通、层次递进和整体协同的系统性育人过程。通过系统优化育人生态，推动思政课教学实现循序渐进、纵向贯通和同向协同，促进知识传授、价值引领与能力培养有机统一。

The integrated construction of ideological and political courses across primary, secondary, and higher education is an inevitable requirement for implementing the fundamental task of fostering virtue through education. At present, the integrated teaching of ideological and political courses across different educational stages still suffers from poor connection among stages, mismatched levels of teaching content, incompatibility between teaching methods and students’ cognitive development, and imperfect coordination mechanisms. In response to the above‑mentioned dilemmas, guided by materialist dialectics as the methodological guideline, the integrated teaching of ideological and political courses across primary, secondary, and higher education is not a simple superposition of curriculum content for different educational stages. Instead, under the overarching goal of fostering virtue through education, educational elements of various stages follow the law of students’ growth and form a systematic educational process that realizes vertical connection, hierarchical progression and holistic coordination through the movement of contradictions. By systematically optimizing the educational ecology, we can drive ideological‑political teaching toward gradual progress, vertical coherence and coordinated development in the same direction, and advance the organic unification of knowledge imparting, value guidance and competence cultivation.
