演示实验是高中化学实验教学中的重要组成部分,随着新课程改革的不断深化和提升,笔者对高中化学演示实验进行了不断地反思、创新和优化,充分发挥演示实验的功用,以营造更加和谐、充满活力、简洁高效的课堂氛围,从而有效地激发学生的学习兴趣。一、高中化学演示实验创新的必要性演示实验与探究性验、验证实验在化学实验教学中所起的功用是不同的。演示实验通过教师在课堂上的演示,将化学知识以直观、直接、有效的方式呈现给学 Demonstration experiment is an important part of senior high school chemistry experiment teaching. With the continuous deepening and promotion of new curriculum reform, the author constantly rethinks, innovates and optimizes high school chemistry demonstration experiment and gives full play to the function of demonstration experiment to create more Harmonious, vibrant, simple and efficient classroom atmosphere, so as to effectively stimulate students interest in learning. First, the need for high school chemistry demonstration experiment innovation Demo and exploration Experimental and verification experiments in chemistry experiment teaching played a different role. Demonstration experiment through the teachers in the classroom presentation, the chemical knowledge in an intuitive, direct and effective way to learn
