一、问题的提出 化学是一门以实验为基础的理论科学。 化学实验是化学理论知识产生和发展的源泉,又是检验理论的最高法庭,离开化学实验,化学理论就无从产生、证实和发展;离开化学理论对实验的指导,化学实验也不能更有效地向广度和深度进军。实验和理论都是化学教学的基本内容。为此,提高化学教学质量的努力,不仅要反映在理论知识的提高上,也要落实到实验水平的提高中。
First, the question put forward Chemistry is an experimental theory-based science. Chemical experiments are the source of the production and development of chemical theory knowledge and the supreme court of test theory. Chemical experiments can not be produced, confirmed and developed after leaving chemical experiments. Chemical experiments can not be conducted more efficiently and efficiently Breadth and depth into. Experiments and theories are the basic contents of chemistry teaching. Therefore, efforts to improve the quality of chemistry teaching should not only be reflected in the improvement of theoretical knowledge but also in the improvement of experimental standards.
