化学是一门以实验为基础的科学。实验教学既是化学知识教学的基础,又是提高学生学习化学兴趣的有效手段。但是实验教学不是教师只按书本上的实验方法、步骤与同学一块学习,而是要求教师配合中学化学教材不断地研究探索、精心去创设一些情趣的实验,才能提高学生学习化学的兴趣。可见在化学教学中特 Chemistry is an experiment-based science. Experimental teaching is not only the basis of chemical knowledge teaching, but also to improve students' interest in learning chemistry. However, experimental teaching is not just a book by teachers on the experimental methods and steps to learn together with their classmates, but requires teachers to cooperate with the middle school chemistry textbooks continue to explore and elaborate to create some fun experiments, in order to enhance students interest in learning chemistry.
