化学是一门基础性学科,又是一门以实验为基础的学科.化学新课标指出:教师要注意改进传统的实验教学,精心设计各种探究性实验,促使学生主动学习,逐步学会探究.新课标提出了化学实验探究的重要性.但在应试教育的影响下,有些教师为了省时间,忽视了化学实验操作,化学实验成为讲实验、背实验,学生机械的记忆实验步骤、内容、现象等,这不利于学生学习兴趣的激发,不利于培养学生分析问题、解决问题的能力,
Chemistry is a basic discipline and an experiment-based subject.New chemistry standard indicates that teachers should pay attention to improving the traditional experimental teaching, elaborately design various exploratory experiments, encourage students to take the initiative to learn, and gradually learn to explore The new curriculum proposed the importance of exploring chemical experiments.But under the influence of examination-oriented education, some teachers neglected the operation of chemical experiment in order to save time, and chemical experiment became the experimental steps of experiment in memory of experiment, back experiment and student machinery , Phenomenon, which is not conducive to the excitement of students interested in learning, is not conducive to students’ ability to analyze and solve problems,
