美国《K-12科学教育框架》描绘了美国科学教育的图景并构建了"学习进阶"模型,以使学生在科学工程实践、跨学科概念和核心概念3个维度掌握"精而深"的知识,以及形成解决实际问题的能力.化学核心概念是化学学科教学的灵魂,探讨美国《K-12科学教育框架》化学核心概念对我国化学学科教学具有一定的启示.

American K-12 depict the picture of the science education in the United States and the construction of the ＂learning progression＂ model in order to make the students in scientific and engineering practice, crosscut- ting concepts and core ideas of three dimensions master fine and deep knowledge and solving practical problems ability. Core ideas of chemistry is the soul of chemical instruction. The discussion on core ideas of chemistry in K- 12 has some enlightenment to the instruction of chemistry.
