一、化学课堂教学的“生活化”问题的提出1.化学是一门密切联系生活的学科众所周知,化学在推动人类文明发展的进程中起到了不可估量的作用。人类社会生活的各个方面,从衣食住行到高科技太空探险,从纸笔墨砚到迅速发展的计算机技术等等,无一不和化学有着密切的关系。能源、环境、材料、食品、药品等社会各界普遍关注的热点问题,其产生、发展乃至最终解决,都离不开化学。当然,从辩证的角度来看,任何事情都有其两面性,化学在推动社会进步的同时,也会对人类社会造成一些负面的影响,如能源的消耗、大气的污染、温室效应等,这些似乎是不可避免的,但运用化学手段可以找到解决问题的方案,如寻找可替代能源——氢能、可再生能源等,并采取相应的净化措施以及限制污染的排放。
First, chemistry classroom teaching “life ” proposed the issue 1. Chemistry is a closely linked life science As we all know, chemistry in promoting the development of human civilization has played an inestimable role. All aspects of human social life, from the basic necessities of life to high-tech space exploration, paper and ink from the ink to the rapid development of computer technology, etc., are all closely related with chemistry. Energy, the environment, materials, food, medicine and other social issues of universal concern, its production, development and eventually resolved, are inseparable from chemistry. Of course, from a dialectical point of view, everything has its two sides. Chemistry, while promoting social progress, will also have some negative impacts on human society, such as energy consumption, air pollution and the greenhouse effect. These seem to be Is inevitable. However, chemical solutions can be used to find a solution to the problem, such as finding alternative sources of energy - hydrogen, renewable energy, etc., and adopting appropriate purification measures to limit pollution emissions.
