化学是一门以实验为基础的学科,在化学教学中,实验的作用是其他教育无法替代的。化学实验对学生学习兴趣、观察能力、动手操作能力、思维能力和科学探究能力等的培养发挥着重要作用。因此,在化学教学中,如何选好、用好、做好实验,充分发挥实验的各项功能,培养学生的各种能力,应是化学教师教学研究的重要课题。一实验可激发学生的学习兴趣在上课前,可以设计一两个富有启发性的实验,利用实验中的奇妙现象,引导学生思考,使学生产生激奋、高昂的 Chemistry is an experiment-based discipline, in chemistry teaching, the role of the experiment is that other education can not be replaced. Chemistry experiments play an important role in the cultivation of students’ interest in learning, observation, hands-on ability, thinking ability and scientific inquiry ability. Therefore, in chemistry teaching, how to select, use, experiment well, give full play to all the functions of experiment, and cultivate various abilities of students should be an important subject of chemistry teachers’ teaching research. An experiment can stimulate students’ interest in learning Pre-class, you can design one or two inspiring experiments, the use of the wonderful phenomena in the experiment, to guide students to think, so that students produce exciting, high
