华罗庚先生始终强调把厚书读薄,把薄书读厚。简短的几个字,其实是学习方法的深刻概括。一本厚书,经过认真阅读、反复理解、分析归纳、抓住本质、融会贯通,就是由厚到薄的过程;一本小册子,经过充分阅读,挖掘内涵,寻找对应的实例,让内容不断充实、丰富起来,就是由薄到厚的过程。初中数学的教与学也是在厚与薄之间不断往返、不断上升的过程,教师如此,学生也如此。几何练习千千万,根本做不完,也没必要全做完。但是,几何学习是不少学生始终畏惧的内容。那怎么让学生的几何学习效果好、效率高呢?在多年的教学中,我越来越深刻地认为,基本图的教学是不可忽略的,怎么将题海
Mr. Hua Luogeng always emphasized reading thick books and reading thick books. A few words in short, in fact, a profound summary of learning methods. A thick book, after careful reading, repeated understanding, analysis and induction, grasp the essence, mastery, is the process from thick to thin; a booklet, after full reading, mining content, find the corresponding examples, so that the content is constantly enriched , Rich, is from thin to thick process. Teaching and learning in junior middle school mathematics is also a process of constant reciprocation between the thick and the thin, teachers, and so on. Geometrical dozens of millions, simply endless, there is no need to finish all. However, geometry learning is the content that many students always fear. How to make students learn the geometric effect of good, high efficiency? In many years of teaching, I am more and more deeply believe that the teaching of the basic diagram can not be ignored, how the problem will be the sea
