北师大一年级下册《发新书》一课,是两位数加两位数进位加法的新授课。经过多次的反复推敲整改,我对数学课的教育理念有了很深的感悟,对教材的理解有了更深的认识,感受颇多,现与大家一起分享。一、初试算法多样化是北师大教材一个鲜明特点,初次上这节课时,我按部就班地加入了学生算法的展示。其实,我原来一直觉得无论什么方法都应该是为竖式服务的。口算,小棒,计数器,这些方法只是开拓学生思维,真正要教会学生,还得是竖式。因此,我在第一次试讲时,心里暗暗敲定,学生能说出什么方法,就展示什么,没有的就跳过去,或者组织学生看书。 Beijing Normal University, the first year under the book “issued a new book” a class, is a two-digit plus two-digit addition of the new lectures. After many repeated scrutiny rectification, I have a deep understanding of the concept of mathematics education, understanding of teaching materials have a deeper understanding, feel a lot, now we share with you. First, the diversification of the first test algorithm is a distinctive feature of Beijing Normal University teaching materials, the first time on this class, I step by step to join the student algorithm display. In fact, I had always felt that no matter what method should be vertical service. Mouth count, stick, counter, these methods are only to develop students thinking, really want to teach students, have to be vertical. Therefore, when I first tried my speech, I secretly finalized what the students could say, what they would show, and if they did not, they would skip or organize the students to read the book.
