近日,阅读了教坛新秀张齐华老师的著作《审视课堂:张齐华与小学数学文化》一书,一口气翻完了全书,数学文化一词映入眼帘。相信大多数读过上述著作,或是实际观摩过相关教学的数学教师都会对张齐华老师所执教的《圆的认识》典型教学案例产生深刻的印象,对其中“圆的文化”的诠释可谓淋漓尽致。一、让数学实现“华丽转身”片断:师:有人说,因为有了圆,我们的世界才变得如此美妙而神奇。其实在我们人类生活的每一个角落,圆都扮演着重要的角色,并成为美的使者和化身。让我们一起来欣赏——(伴随着优美的音乐,教者运用媒体手段展
Recently, reading the book of the teacher rookie Zhang Qihua, “Examining the Classroom: Zhang Qihua and Primary School Mathematical Culture,” a book, one after another, the word mathematically came to the fore. I believe most of the math teachers who have read the above books or actually observed the related teaching will have a profound impression on the typical “round understanding” teaching cases taught by Teacher Zhang Qihua, and the interpretation of “round culture” can be described as Most vividly First, let mathematics achieve “gorgeous turn ” piece: Teacher: Some people say that because of the circle, our world has become so wonderful and amazing. In fact, in every corner of our human life, the circle plays an important role and becomes the messenger and incarnation of the United States. Let us enjoy together - (along with the beautiful music, teachers use the media show
