This paper develops a three-tiered argument regarding the collaborative mechanism of the "Grand Ideological and Political Course": first, it explains "why collaboration iecessary" by addressing the impact of AI on public opinion, the imbalance of in-class and out-of-class resources, and the obstruction of bidirectional empowerment between teachers and students; secont elucidates "the value of collaboration" from three dimensions: the changing landscape of the century, the cultivation of souls, and the enhancement of appeal; finally, it proposes four major ies—"teacher-led, tripartite collaboration, multi-party linkage, and quality anchoring"—to provide a systematic solution for "how to collaborate," thereby achieving collaborative education involving all tie and space, all educational stages, and all stakeholders.
