化学是以实验为基础的学科,实验能力也是学生综合能力中真正最具有“综合”意义的一种能力,在化学学科教学中起着重要作用。在化学学科中,任何理论(或假设)的提出,发展和完善,都有一定的实验事实做依据,许多理论的形成都是要经过“实验事实—理论的建立—再实验—理论的发展和完善”这样的一个过程,而且新课标高中化学第一章讲的便是从实验到化学。由此可以看出实 Chemistry is an experiment-based discipline. Experimental ability is also one of the most comprehensive “comprehensive ” capabilities in students’ comprehensive abilities. It plays an important role in chemistry teaching. In the field of chemistry, any theory (or hypothesis) put forward, develop and improve, there is a certain experimental basis for the fact that many theories are formed to go through “experimental facts - the establishment of theory - re-experimental - the development of the theory And improve ”This process, and the new curriculum standard high school chemistry is about the first chapter from the experiment to chemistry. It can be seen from the real
