化学是一门研究物质反应过程、现象及本质的学科,而中学化学是化学学科中的基础部分,这与中学其他科目理论性强的特点形成鲜明对比。利用实验进行教学在化学教学中有极其重要的作用。课堂实验不仅能够帮助学生了解最基础的化学知识,分清化学概念,了解整个的化学反应过程,培养学生的动手操作能力。所以,在实际的课堂教学 Chemistry is a discipline that studies the process, phenomenon and essence of matter, while chemistry in middle school is a fundamental part of chemistry, in stark contrast to the theoretical features of other subjects in high school. The use of experimental teaching in chemistry teaching has an extremely important role. Classroom experiments can not only help students understand the most basic chemical knowledge, distinguish chemical concepts, understand the entire chemical reaction process, and develop students’ hands-on ability. So, in the actual classroom teaching
