在高中化学教学中引入手持技术,不仅使某些在当前条件下无法实现的实验成为可能,还能促使学生了解先进的科学技术,获得科学的学习方法,形成正确的学习态度。文章以金属的电化学腐蚀为例,借助于手持技术捕捉化学反应过程中的细微变化,从而帮助学生理解析氢腐蚀与吸氧腐蚀。一、手持技术在高中化学实验教学中的应用意义1.使实验更加现代化、简易化、综合化手持技术使得实验教学与国际接轨,化学实验不仅在实验室进行,还可以在户外等场所
The introduction of hand-held technology in high school chemistry teaching not only makes certain experiments that can not be achieved in the current conditions, but also enables students to understand advanced science and technology, obtain scientific learning methods and form a correct learning attitude. The article takes the electrochemical corrosion of metal as an example, with the help of hand-held technology to capture the subtle changes in the chemical reaction process to help students understand the hydrogen evolution and oxygen corrosion. First, the application of hand-held technology in high school chemistry experiment teaching Significance 1. To make the experiment more modern, simple and comprehensive Hand-held technology makes the experiment teaching and international standards, chemical experiments not only in the laboratory, but also in outdoor places
