化学是一门以实验为基础的学科。化学实验教学的首要任务是如何激发学生对学习化学的兴趣,提高他们学习化学的主动性和积极性。在实验教学中要引导学生学会观察,能够采用多种实验方法进行自主探究,通过实验活跃学生思维,提高课堂效率。 Chemistry is an experiment-based discipline. The first task of chemistry experiment teaching is how to stimulate students' interest in learning chemistry and improve their initiative and enthusiasm to learn chemistry. In experimental teaching, we should guide students to learn to observe, to use a variety of experimental methods for independent exploration, through the experimental active student thinking, improve classroom efficiency.
