初中化学是九年义务教育阶段中一门最基础的自然科学,是化学教育的启蒙和基础阶段,它与工业、农业、国防建设业以及环境保护等方面有着密切的关系。我们必须从初中抓起,从培养学生学习兴趣、激发他们的求知欲入手,通过演示实验法和探究式教学法,提高课堂教学效率,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
Junior high school chemistry is one of the most basic natural sciences in the nine-year compulsory education. It is an enlightenment and basic stage of chemistry education. It has close relations with industry, agriculture, national defense construction and environmental protection. We must start from the middle school, from cultivating students’ interest in learning and stimulating their thirst for knowledge. By demonstrating the experimental method and inquiry-based teaching method, we should improve the efficiency of classroom teaching and guide students to break through the chemistry lesson of junior high school with less task, content and some scattered Confusing concepts and other contradictions to help them pass the basic concepts related to experimental operation so that they can better grasp the basic knowledge and basic skills to develop their intelligence to develop their flexibility to use chemical knowledge to solve problems independently
