著名化学家傅鹰先生曾说过:“化学是实验的科学,只有实验才是最高的法庭。”著名化学家戴安邦教授生前反复强调:“加强实验,无论如何都不过分。”教化学的同行都明白,讲实验不如给学生演示实验,演示实验不如让学生亲自动手做实验,因为仅仅通过演示实验,甚至只讲而不做实验,学生只运用了眼和脑,在理解上存在较大困难;而动手实验则不同,它使学生具有身临其境的感受,体会到知识生成的全过程。因此,实验教学常被作为一种重要的教学 The famous chemist Mr. Fu Ying once said: “Chemistry is the science of experiment, and only the experiment is the highest court.” Professor Dai Anbang, a famous chemist, repeatedly stressed in his lifetime that “to strengthen the experiment is by no means excessive.” " Teach chemistry colleagues understand that the experiment is not as good as the experiment to the students to demonstrate the experiment is not as good as giving students hands-on experiments, because only through demonstration experiments, and even speak without experiment, students only use the eyes and brain, in understanding There is greater difficulty; and hands-on experiment is different, it enables students to have immersive feelings, experience the whole process of knowledge generation. Therefore, the experimental teaching is often used as an important teaching
