化学是一门以实验为基础的自然科学,实验是化学的重要组成部分和教学实现途径,化学实验中蕴含着化学原理、化学反应现象和化学探索思考基本点.高中化学新课程标准要求教师优化实验教学方式,使学生在实验的基础上主动完成化学知识体系建构.在当前的教学实践中,化学教学多注重教师讲授,实验仅作为教师讲授的辅助活动,而非学生化学学习的主要途 Chemistry is an experiment-based natural science, experiment is an important part of chemistry and teaching methods, chemistry experiments contain the basic principles of chemical principles, chemical reaction phenomena and chemical exploration and reflection. The new high school chemistry curriculum standard requires teachers to optimize In the current teaching practice, chemistry teaching places more emphasis on teachers ’teaching, and experiments only serve as auxiliary activities taught by teachers, rather than the main way of students’ chemistry learning
