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。 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.
