目前中学教学仍以分科教学为主。学生获取的知识绝大部分是孤立的,怎样帮助他们综合多学科思维方法,解决疑难问题,跨过这些看似不可逾越的鸿沟呢?那就要寻找跨学科知识的结合点。在长期的化学教学中我发现,学生在解决化学学科的一些问题时没有找到好的方法,使问题解决复杂化。对于这些问题,如果用相关的数学知识来解决,既达到事半功倍的目的,又能使教学中的难点深入浅出,使学生受益匪 At present, secondary education is still based on sub-teaching. The vast majority of students acquire knowledge is isolated, how to help them integrate multidisciplinary thinking methods to solve difficult problems, across these seemingly insurmountable gap? It is necessary to find a combination of interdisciplinary knowledge. In the long-term chemistry teaching, I found that students did not find a good solution to some of the problems in chemistry and made the problem solving complicated. For these problems, if the relevant mathematical knowledge to solve, both to achieve a multiplier purpose, but also make teaching difficult in simple terms, so that students benefit bandit
