美国高中理科课程设置顺序调整研究及启示

The Study and Inspiration on the Adjustment of Science Curriculum Sequence in American High Schools

美国高中理科课程设置长时间一直延续生物-化学-物理（B-C-P）的顺序。为了提高全体公民的科学素养，目前正努力实现物理-化学-生物（P-C-B）的课程设置顺序的改变。这种基于科学素养提高的课程顺序调整，对我国新课程改革中理科课程实施具有重要启示意义。

The science curriculum sequence of biology-chemistry-physics (B-C-P) has existed for a long time in American high schools. In order to enhance all the citizens' scientific literacy， curriculum sequence is shifted to physics-chemistry- biology (P-C-B). This adjustment of curriculum sequence is based on the improvement of scientific literacy， and it is a very important inspiration to our new curriculum reform.
