一、教材设计的螺旋性——让习题成为学生数学学习前后贯通的连接点小学数学教材采用螺旋式编排,针对学生的接受能力,一般把同一知识结构系列中的内容划分为几个阶段,每一个阶段的内容螺旋上升,逐级提高。我们教者很重要的任务就是通读全套教材,掌握某一知识结构中的内容分布在哪些年级、各年级内容之间的内容联系,把知识的连续性与教学的阶段性统一起来,有效避免教学中的盲目处理和点状随意。在研读教材的过程,你不难发现,很多习题起到了前后贯通的作用,如果教者用好教材中的某些习题,会让学生头 First, the material design of the helicity - Let the exercise become a connection before and after the students math learning point The primary school mathematics textbooks using spiral arrangement, for students’ acceptance, the general knowledge of the structure of the series is divided into several stages, each The content of a spiral rises and rises step by step. A very important task for our teachers is to read through the whole set of teaching materials to grasp the contents of the contents in any grade and grade structure in a certain knowledge structure and to unify the continuity of knowledge with the stage of teaching to effectively prevent teaching In the blind treatment and arbitrary point. In the process of studying materials, you can easily find that many exercises played a role in tandem, if the teacher to make good use of some of the exercises in the textbook, make the students head
