化学实验是化学科学的灵魂,是学生认识化学世界的窗口,是学习化学知识的主要手段.因为实验有助于学生理解和巩固知识,培养实验能力,掌握科学方法.由于通过实验能使学生受到从形象思维跨越到逻辑思维的训练,并促进发散思维与聚合思维的相互统一.因此,实验教学已成为培养学生创造性思维的重要环节.在实验教学中,教师不仅要圆满完成规定的演示实验,更为重要的是要在已有实验的基础上,根据教学需要和学生在学习过程中出现的实际情况,善于改造已有的演示实验,进行实验探索研究.这样做不仅使学生更有效更容易掌握有关化学知 Chemistry experiment is the soul of chemistry, it is a window for students to know the chemistry world and is the main method to learn chemistry knowledge, because it helps students to understand and consolidate knowledge, develop experimental ability and master scientific methods. From the thinking of the image to the training of logical thinking and promote the divergence of thinking and the unity of thinking.Therefore, experimental teaching has become an important part of cultivating students’ creative thinking.In the experimental teaching, teachers not only need to successfully complete the prescribed demonstration experiment, More important is based on the existing experiment, based on the teaching needs and students in the learning process of the actual situation, be good at rebuilding the existing demonstration experiments, experimental exploration and research.This will not only make students more effective and easier Know about chemistry
