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极易混淆等矛盾,帮助他们过好基本概念关,实验操作关等,使他们更好地掌握基础知识和基本技能,开发他们的智力,培养他们灵活运用化学知识独立解决问题的能力。下面就自己在多年工作实践中的一些做法,谈点滴体会。
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 learn relevant majors, but also lay a foundation for graduates to participate in work-solving and solve some practical problems. In order to improve the quality of chemistry teaching in a large area, we must start from the middle school, start from cultivating students’ interest in learning and stimulating their curiosity, starting from improving the efficiency of classroom teaching, guiding students to break through junior high school chemistry lesson, less task, content and Some concepts can be easily confused with other contradictions to help them pass the basic concepts and experimental operations so that they can better grasp the basic knowledge and basic skills, develop their intelligence and develop their ability to use chemical knowledge to solve problems independently. The following on their own practice in many years of practice, talk about experience.
