新课标明确指出化学实验是高中化学教学的基础,通过实验来探究、发现一些最基本的科学规律。同时高中化学实验也是高中学生学习化学、探索化学和体验化学的必要的途径和手段。化学研究的是物质的结构、性质、组成以及变化等。理论性的概念多且抽象,学生理解起来有困难。这时化学实验课就起到了不可替代的作用,它将抽象的化学知识具体化,使学生很容易的接受和理解。其次化学实验课也是培养学生学习化学知识兴趣的重要途径,在实验过程中,学生在老师的细心引导下一步一步地深入,通过化学实验总结出相应的化学知识,这样不但加深了化学知识的印象,更能激发学生积极探索的兴趣,增强了学生学习化学的新动力。
The new curriculum clearly pointed out that the chemical experiment is the basis of high school chemistry teaching, through experiments to explore and discover some of the most basic scientific laws. At the same time, high school chemistry experiments are also the necessary ways and means for senior high school students to learn chemistry, explore chemistry and experience chemistry. Chemical research is the material structure, nature, composition and changes. Theoretical concepts and more abstract, students understand it difficult. At this time, the chemistry experiment class has played an irreplaceable role. It embodies the abstract chemistry knowledge so that the students can easily accept and understand it. Second, the chemistry experiment class is also an important way to cultivate students’ interest in learning chemical knowledge. During the experiment, the students step by step through the careful guidance of the teacher and summed up the corresponding chemical knowledge through chemical experiments. This not only deepens the impression of chemical knowledge , More able to inspire students to actively explore the interest and enhance students new learning chemistry.
