俗话说:“台上一分钟,台下十年功。”要想课堂高效,课前就必须做好充分的教学准备,其中撰写一个高质量的教学设计尤其重要,而教学设计质量的高低源于对数学课程标准和教材的把握、对学情的了解和教法学法的选择。下面仅以计算教学为例浅谈如何研读小学数学教材。一、研究教学内容的前后联系数学知识是在一些最基本的概念和原理的基础上逐步发展形成的,如果把最基本的概念和原理比作树根和树干的 As the saying goes: “One minute on the stage, the audience ten years of work.” "In order to be effective in class, must be fully prepared for teaching before class, of which writing a high quality teaching design is particularly important, and teaching design quality High and low stem from the grasp of mathematics curriculum standards and teaching materials, understanding of learning and choice of teaching method. The following only to calculate teaching as an example to talk about how to study primary school mathematics textbooks. First, the study of teaching content before and after the connection Mathematical knowledge is based on some of the most basic concepts and principles of the gradual development and formation, if the most basic concepts and principles as the root and trunk
