实验教学在化学教学中具有举足轻重的作用,是学好化学的重要途径,不但课本上的实验要做,而且还要想方设法在教学过程中多设计一些补充实验,突破教学的重点和难点,培养学生的形象思维能力.一、演示实验让学生得以全面发展实验教学能够给学生以直观的感觉,因此没有实验的化学课堂,就会是淡而无味的课堂.著名化学家戴安邦教授曾作过这样的阐述:“无论从何种角度分析,化学实验课都应该是实施 Experimental teaching plays an important role in chemistry teaching. It is an important way to learn chemistry. Not only the experiments on textbooks but also the ways to design more supplementary experiments in the course of teaching, to break through the key and difficult points of teaching and to train students’ First, the demonstration experiment allows students to develop in an all-round way Experimental teaching can give students a visual feeling, so there is no experimental chemistry classroom, it will be a light and tasteless classroom.A famous chemist Professor Dai Anbang made such an elaboration: ”Regardless of the point of view, chemistry lab classes should be implemented
