实验不仅是使学生获取化学知识、认识化学规律、形成化学概念、提高各种能力的重要途径,而且此过程对学生的创新精神和创新能力的培养,是其他学科所不能替代的.因此,化学教学必须立足于实验.一、开拓思维,发掘资源中学化学实验多为验证性实验.验证性实验是用实验来论证已学过的化学知识的正确性,在实验中学生处于被动接受知识的状态,这种实验模式缺乏对学生的思维能力、动手实践能力、创新精神及创新能力的培养.而将教材中的某些验证性实
Experiments are not only an important way for students to acquire chemical knowledge, recognize chemical laws, form chemical concepts and improve various abilities, but also to train students’ innovative spirit and innovative ability, which can not be replaced by other disciplines.Therefore, Teaching must be based on the experiment.First, open up thinking and explore resources High school chemistry experiments are mostly confirmatory experiments.Critical experiments are used to demonstrate the correctness of the chemical knowledge that has been learned, in the experiment students are in a passive state of knowledge, This experimental mode lacks the training of students’ thinking ability, hands-on practical ability, innovative spirit and innovative ability,
