在数智技术驱动下，高校思政教育空间发生深刻变化。从马克思主义认识论和教育生态学相结合的跨学科视角审视，高校思政教育亟须改变“单向”“单线”“单元”的物理空间，向“多向”“多线”“多元”的立体化场域方向发展。北京交通大学通过课堂空间拓展——课内与课外贯通，主体多元共生——校内与校外联动，数智技术赋能——线上与线下融合，形成“师—生—AI”交互共同体，以促进数智时代思政教育场域立体化发展，实现从“知识传授”到“价值认同”再到“行为践行”的实质性跃升。这种探索为深化高校思政教育教学改革提供了可资借鉴的经验。

Driven by digital‑intelligent technologies， the space of ideological and political education in colleges and universities has undergone profound changes. From an interdisciplinary perspective integrating Marxist epistemology with educational ecology， university ideological and political education urgently needs to transform its unidirectional， linear and unit‑based physical space into a multi‑directional， multi‑linear and multi‑faceted three‑dimensional field. By expanding classroom space to integrate in‑class and out‑of‑class scenarios， enabling diverse subjects to co‑exist through university‑external linkage， empowering education with digital‑intelligent technologies to realize online‑offline integration， and building a teacher‑student‑AI interactive community， Beijing Jiaotong University has greatly advanced the three‑dimensional development of the ideological and political education field in the digital‑intelligent era. It has achieved a substantive leap from “knowledge impartation” to “value identification” and further to “behavioral practice”， offering referential experience for relevant reforms.
