现代科学已经淡化了学科间的界线,在高中设置的学科中,生物和化学是存在交叉渗透点最多的两门学科。新课改主张学科间相互交叉渗透,给学生一个较大的知识接触面和较大的思维发展空间,在教材的编写中也力图做到学科间的渗透。但是我们在教学实践中却发现,由于两学科出现教学进度上的不协调,从而给学生 Modern science has played down the boundaries between disciplines. Among the subjects set in high schools, biology and chemistry are the two disciplines that have the most cross-penetration points. The new curriculum reform advocates interdisciplinary cross-penetration between disciplines, giving students a greater knowledge of the contact surface and a larger space for thinking in the preparation of teaching materials and strive to achieve interdisciplinary penetration. However, in our teaching practice, however, we find that due to the incompatibility of teaching progress between the two disciplines,
