实验是科学的基础,理论的源泉。著名化学家傅鹰教授曾指出:“化学是实验的科学,只有实验才是最高法庭”。化学实验在整个化学教学中,对培养学生实是求是的科学作风,对观察、分析和解决问题的能力的培养和理解化学基本概念,基本知识都起着重要作用。但是,在传统的实验教学中,无机化学实验内容的很大份量是试管试验,仅起着验证理论的作用,在实验教学方法上又往往使学生处于“照方抓药”的被动地位,束缚了学生的主动性。如何改变这种状况,是当前必须改进的重要的问题。另外,由于我校学生大多数来自农村,中学实验条件较差,很少动手实践,他们不会观察反应现象,不知记录哪些问题,更谈不上分析归纳实验事实。因此我们选择了在卤族元素实验后,组织了 Experiment is the foundation of science and the source of theory. Well-known chemist Professor Fu Ying once pointed out: “Chemistry is the science of experiment, only the experiment is the supreme court.” Chemistry Experiments In the whole chemistry teaching, it is a scientific style of seeking truth from facts for the cultivation of students and plays an important role in cultivating and understanding the basic concepts and basic knowledge of chemistry in the ability to observe, analyze and solve problems. However, in the traditional experimental teaching, a large part of the content of inorganic chemistry experiment is a test tube test, which only plays the role of verification theory. In the experimental teaching method, students often stay in the passive position of “taking prescription medicine” Student’s initiative. How to change this situation is an important issue that must be improved at present. In addition, because most of our students come from rural areas, the experimental conditions in secondary schools are poor and rarely used. They do not observe the reaction phenomenon and do not know what problems are recorded, let alone analysis and summing up experimental facts. So we chose to organize after the Halogen element experiment
