化学是一门以实验为基础的科学,中学化学演示实验教学在激发学生的创新意识方面具有不可替代的作用。因此,提高化学演示实验教学质量,已成中学化学教学中的重中之重。为改变长期以来化学教学一直停留在对化学实验进行理论上的分析,教师必须强调化学演示实验教学的重要性,充分发挥化学实验在培养学生能力方面的创新作用。
Chemistry is an experiment-based science. Experimental teaching of chemistry demonstrations in secondary schools plays an irreplaceable role in stimulating students’ innovative awareness. Therefore, to improve the quality of chemical demonstration experiment teaching has become the top priority in chemistry teaching in middle schools. In order to change the long-term chemical teaching has been to stay in the theoretical analysis of chemical experiments, teachers must emphasize the importance of experimental teaching of chemical demonstration, give full play to the innovative role of chemical experiments in the cultivation of students’ abilities.
