化学是一门基础的自然科学,它同农业、能源、材料、资源开发、国防建设以及环境保护等方面有着密切的关系,它对实现我国“四化”建设起着重要的作用。中学化学教学是化学教育的启蒙和基础阶段。它不仅能为学生升入高一级学校学习有关专业奠定基础,也能为毕业生参加工作解决处理一些实际问题打下基础,要想大面积提高化学教学质量,必须从初中抓起,从培养学生学习兴趣,激发他们的求知欲入手,从提高课堂教学效率做起,引导学生突破初中化学课时少、任务重、内容分散及有些概念
Chemistry is a basic natural science. It has close relations with agriculture, energy, materials, resources development, national defense construction and environmental protection. It plays an important role in the realization of China’s “four modernizations”. Chemistry teaching in middle school is the enlightenment and basic stage of chemistry education. It can not only lay the foundation for students to go to higher level schools to study relevant majors, but also lay a solid foundation for graduates to take part in work and solve some practical problems. In order to improve chemistry teaching in a large area, it is necessary to start from middle school, Learn interest, stimulate their curiosity to start, from improving classroom teaching efficiency, and guide students to break through junior high school chemistry Less hours, heavy tasks, content and some scattered concepts
