一、问题提出的背景高三化学复习的主要目的是,帮助考生对已基本掌握的零碎的化学知识进行归类、整理、加工,使之规律化、网络化;对知识点、考点、热点进行思考、总结、处理,从而使学生掌握的知识更为扎实,更为系统,更具有实际应用的本领.但随着一节节机械式的知识点的罗列整理和例题讲解,学生逐渐失去了学习知识的新鲜感和主动性,结果教师讲得累,学生也听得累.如何让旧知识发挥新魅力,使学生乐于融入课堂,是高
First, the background of the question raised The main purpose of the high school chemistry review is to help candidates to have the basic grasp of the fragmented chemical knowledge classification, sorting, processing, so that the law and network of knowledge points, test centers, hot spots to think , Summarize, deal with, so that the students to master the knowledge more solid, more systematic, more practical skills.But with a section of mechanical knowledge points listed and examples to explain, students gradually lost their knowledge of learning Freshness and initiative, the result of teachers tired, students also hear tired.How to make the old knowledge of new charm, so that students willing to integrate into the classroom, is high
