科组研讨课











政治科研讨课一:  

201732日下午第一节课,庹青老师在高三四十班上了一节高三二轮复习研讨课。庹青老师作为政治科组最年轻的教师敢于挑战自我、乐于担当重任,主动要求上公开课,这一举动体现了一位年轻教师好学上进、锐意进取的优秀品质。本节公开课,庹青老师复习的内容是经济活动四环节中的“生产”环节。她善于提出问题,激发学生思考。复习资料上的重点知识,她让学生回归课本,找到原出处,培养学生的教材意识。她关注知识间的内在联系,引导学生思考基本概念间的逻辑关系和知识生成的来龙去脉。她注意提取主干知识的关键词,指导学生通过抓关键词迅速而有效地记住所学的知识。她通过课堂练习培养学生的审题解题能力,实现知识与能力的统一。  

完善建议:1、政治科二轮复习,内容多、时间紧、任务重,是老师讲学生听,还是学生主体、老师主导,需要教师认真研究,不能以教师的主导而代替了学生的主体作用,学生应是课堂的主人。  

2、“一切知识都是从感官开始的”。板书可以给学生展示鲜明具体的知识脉络,有助于学生通过形象感知带动理性思考,深入理解把握知识。二轮复习课也应有必要的板书展示教学内容的框架结构和知识体系,便于学生理解巩固知识,加深印象。  

3、解答主观题是高三复习课中的经常性教学工作,尤其是解答图表类主观题,学生失分多,大部分学生回答图表类主观题能力欠缺。在分析图表类主观题时,教师要放手让学生去解读、提炼、整合图表信息,把解决问题的主动权还给学生,在学生回答的同时老师给予必要的点拨。学生通过思考解决问题,可以展现自身的思维过程,找到思维缺陷。教师最后归纳总结、概括此类题的一般解题过程及其答题规律,这样的操作过程,学生参与其中,切身体验解题思路,感受思考的魅力,会在学生思想深处留下深刻印象。在今后的测试中,若碰到此类题目,学生就可以举一反三、融会贯通。
