化学是一门以实验为基础的自然科学,化学学科的形成和发展,新物质的发现和发明,无不依赖化学实验。在中学化学教学中,实验既是传授化学基础知识的一种手段,又是化学教学的重要目的。因此在新课程改革中,在许多学习内容中增加了实验探究,我们应该充分利用这些探究实验,培养学生科学探究能力,充分发挥学生的主观能动性。 Chemistry is an experiment-based natural science, the formation and development of chemistry disciplines, the discovery and invention of new substances, all rely on chemical experiments. In chemistry teaching in secondary schools, experiments are not only a means of imparting the basic knowledge of chemistry, but also an important purpose of chemistry teaching. Therefore, in the new curriculum reform, experimental exploration has been added to many learning contents. We should make full use of these inquiry experiments to cultivate students 'ability of scientific inquiry and give full play to students' subjective initiative.
