新课程标准改革要求学生在学习过程中能够具备动手能力以及观察能力,而化学演示实验是锻炼和提高学生观察能力以及接受能力的有效教学模式.化学演示实验本身也是高中化学教学内容中较为重点和重要的部分,在教师的化学演示实验过程中学生能够直观的对化学实验现象进行观察,对化学实验规律进行掌握和了解.在充分体现自然界规律与物质反应原理的同时使学生对化学实验本身以及化学教学内容产生浓厚的兴趣.同时在学习以及亲自操作化学实验的过程中掌握实验操 The new curriculum standards reform requires students to have hands-on ability and observation ability in the learning process, and chemical demonstration experiment is an effective teaching mode to exercise and improve students’ observation ability and ability to accept.Chemical demonstration experiment itself is also a high school chemistry teaching content is more focused and An important part of the teacher in the process of chemical demonstration experiment students can intuitively observe the phenomenon of chemical experiments to grasp and understand the rules of chemical experiments in fully reflect the laws of nature and the principle of the material reaction to the students on the chemical experiment itself and the chemistry Teaching content have a strong interest in the same time learning and operating the chemical experiment in the process of master experiment
