实验是探究自然学科的法宝,对于初中生来说化学现象和概念都比较抽象、难懂,如果教师借助实验让学生亲自动手操作和体验化学知识生成和发展的过程,就能产生形象认知,利于知识到能力的迁移。结合一线教学实践对怎样用实验引导学生认知化学知识进行分析。
Experiments are a magic weapon to explore natural sciences. For junior high school students, chemical phenomena and concepts are rather abstract and difficult to understand. If teachers experiment with them to manipulate and experience the process of generating and developing chemical knowledge, Conducive to the transfer of knowledge to ability. Combined with first-line teaching practice on how to use experimental guide students to understand the cognitive chemistry.
