学科 01 · AI
AI 素养与应用
从“什么是 AI、什么不是 AI”到亲手构建 LLM 驱动的工具。下面的资源在动手实践与“安全 + 怀疑”的批判视角之间取得了平衡。

学科 02 · 编程
编程
先积木式编程，再上真正的 Python。每一项推荐都因其教授“用代码思考”而入选—不仅仅是死记语法。
探索者 · 小学到初中

学科 03 · 机器人
机器人
机器人教会的是完整的回路—感知、决策、行动。从第一次可编程的搭建到竞赛级工程，背后都有经过验证的课程体系。

学科 04 · 3D 与 CAD
3D 建模与 CAD
初学者从浏览器 CAD 入门，建造者上手专业参数化工具。两条路径走的是同一条流水线：想法 → CAD → STL → 切片 → 拿在手里的打印件。
探索者 · 小学到初中

- FreeCAD Fully open source — no license games. Rougher UI but maturing fast.
学科 05 · 创新
创新项目
把真实问题从草图推到上线的方法论。Stanford d.school 提供方法、IDEO 提供工作册、现实世界的先例可供参考。
探索者 · 小学到初中
