“思维导图”——数学复习教学的“利剑”八坼中学课题研究课展示
数学思维导图有什么优势?
提高数学的记忆问题














数学思维导图是记忆数学最好的方式
第一:熟知所学知识后,通过回忆绘制思维结构图;
第二:抓住关键知识点进行二次学习;
第三:思维导图与大脑建立链接,每次回顾即对知识的再次巩固。
想想再想想

为了实现学生的自主复习,提升学生的解题能力,6月10日,八坼中学数学组、课题组全体成员一起进行了课例研究活动。






活动首先由教科室马勤良老师开设示范课,马老师从一堂因式分解的数学课入手,先让学生自我寻找问题,初步尝试小组合作解决问题,通过基础题目去发现因式分解的有效方法,在此基础上构建思维导图。接着马老师补充讲解部分非常规因式分解题,同时穿插介绍一些新方法,如:整体思想、拆项或者添项、换元等,让学生补全思维导图,最后学生集思广益,将各种有效的因式分解方法大串联,选用出最为适合的方法。一堂课由“图”入手,并以此结尾,充分发挥了学生主体地位,激发了学生的学习兴趣,实现了学生对所学知识的自主复习,并以此类推,延伸至各个学科。真正达到“事半功倍”的效果。



课后,课题组及时进行课堂反馈。马老师介绍了这堂课所要实现的教学目标,以及此类复习课所需注意的问题,同时对课题组提出相应的思考方向,倡导大家利用暑假时间,思考有关学生有效复习方面的措施,同时在下学期新授课方面也要所创新,从而来提升学生学习的有效性。随后,课题主持人吴春喜校长也做出详细的点评,号召课题组成员要以课题为抓手,落实课堂,研究学生,研究学情,不断提升自己的教学能力和科研水平。
