美国研究理事会（NRc）新近发布的K-12（科学教育框架（草案）》采用“核心学科理念”、“跨学科要素”和“科学与工程实践”三个维度重构美国科学教育标准，这标志着国际科学教育思想的发展进入了一个新阶段。考虑中美科学教育的历史文化与现实情况的差异，我们需要在认真研究的基础上借鉴这一最新进展。“,”In order to reconstruct the National Science Education Standard, the National Research Council of USA has recently issued its A Framework for Science Education-Preliminary Public Draft which is structured in three dimensions： core disciplinary ideas, cross-cutting elements, and scientific and engineering practices. This may denote that a new stage of science education has come into being. Considering the disparity between China and USA in terms of the history and present situation of science education, we need to conduct sincere research on this new development and draw some valuable references.
