有关“过负”问题的研究，浩瀚无穷，但它是一个概念，还是一个判断，则始终没有提出过。这个缺失，直接制约了减负研究的深入，对减负政策及其实践都带来不利影响。本文认为，“过负”是概念与判断的复合体，但首先应作为一个概念来揭示，因为它应对着一种独立的社会现象和教育现象，它不是能在“课业”“学业”或“课程”范畴中，可加以揭示和刻画的现象或问题。“过负”内涵，可以归结为四点：外驱化、高压化、片面化和高耗化。相应地，减负直接目的或目标由此归结三个：保护或维护好儿童的身心材质这一民族的最根本的天赋资源；保障和落实儿童权利和权益；给儿童或学生留出自我发展或自主发展的必要时空。减负的这三大目的或目标，同时也体现为向“建设现代社会和现代教育”这一最终目标的努力和驱近。
