化学是一门以实验为基础的自然科学。化学实验在学科发展中占据着重要地位,它不仅是科学研究中最重要最基本的手段之一,而且在人才培养方面,化学实验亦是塑造学生综合素质的一个重要环节。而且化学实验是化学教学的载体。它不仅是一种实践活动,还是一种重要的感性认识方法。化学实验具有直观具体、形象生动的特点,而这正符合中学生从感性到理性、从具体到抽象、从简单到复杂的认知特点。实验可以提供精心筛选和简化过的感性材料,它能使学生对化学事实获得直观、具体的认识;在化学教学中运用实验还可以给学生学习化学创造一个良好的情景,使学生主动去探索新知识、获取新知识;通过学生的观察实验,亲身体验化学实验过程,使学生掌握实验的基础知识和基本方法,形成实事求是的科学品质,培养他们的实验技能、分析问题和解决问题的能力。
Chemistry is an experiment-based science. Chemistry experiments occupy an important position in the discipline development. It is not only one of the most important and basic means in scientific research, but also is an important part of shaping the overall quality of students in terms of personnel training. And chemical experiments are the carrier of chemistry teaching. It is not only a practical activity, but also an important perceptual method. Chemistry experiments are intuitive and vivid, which is in line with the cognitive characteristics of middle school students from perceptual to rational, from concrete to abstract, and from simple to complex. Experiments can provide careful screening and simplification of the perceptual material, which enables students to get an intuitive and specific understanding of the chemical facts; the use of experiments in chemistry teaching can also provide a good scenario for students to learn chemistry and enable students to take the initiative to explore new Knowledge, access to new knowledge; through student observation experiment, first-hand experience of chemical experiment process, enable students to master the basic knowledge and basic methods of experiment, to form the scientific quality of seeking truth from facts, to develop their experimental skills, problem analysis and problem-solving skills.
