一、动态呈现,拓展思维空间现行人教版小学数学教材为我们提供了丰富的习题教学资源,从基础性练习、综合性练习、拓展性练习到后续的铺垫性练习,充分体现了知识内在的层次性。但因为是文本形式,是以平面、静态的方式呈现,往往将学生的思维框在了一个很小的范围内,学生的思考空间变得狭隘,从而导致学生的思维不能得到充分的发展。因此,教师应根据教学实际、学生的认知规律及生活经验,适当调整习题呈现方式,把静止的资源活动化,牢牢地抓住学生的眼球,使习题呈现更贴近生活、富于情趣,从而创造出习题、情境、活动三位一体的立体教材,拓展学生的思维空间。
First, the dynamic presentation, to expand the space of thinking Current PEP mathematics textbooks provide us with a wealth of exercises teaching resources, from basic exercises, comprehensive exercises, extended exercises to follow the practice of bedding, fully embodies the inherent knowledge Hierarchical. However, because it is a textual form, it is presented in a flat and static way. It tends to put the thinking of students in a very small area, and students ’thinking space becomes narrow. As a result, students’ thinking can not be fully developed. Therefore, teachers should be based on teaching practice, students’ cognitive rules and life experience, appropriate adjustments to exercise presentation, the stationary resources of the activity, firmly grasp the eyes of students, the exercises appear closer to life, full of fun, Thus creating exercises, situations, activities trinity of three-dimensional textbooks, to expand students’ thinking space.
