【摘要】：正纵观北师大版小学数学教材关于图形的认识的教学,学生的操作活动贯彻始终。小学生乐于动手,借助动手操作能使学习过程有趣而生动。同时小学生的思维是由形象思维向抽象思维逐步过渡的,学生在教师的引导下,经历各种操作活动,才有可能积累大量的感性材料,从而形成表象,并进一步加工提升,进而形成对图形的理性认识,对相关概念的深刻把握。但反观我们的课堂,有的教师在引导学生操作时,或流于形式,或浅尝辄止,没有让操作活动变得实用有效。笔者觉得在教学中应该注意以下几点。一、操作材料要精选操作材料必须要服从于我们的教学内容和要达成
[Abstract]:Looking at the Beijing normal University version of primary school mathematics textbooks on the understanding of graphics teaching, students throughout the operation activities. Pupils are willing to do it. With the help of hands-on operation, the learning process can be interesting and vivid. At the same time, the thinking of primary school students is gradually transition from image thinking to abstract thinking. Under the guidance of teachers, students experience a variety of operational activities. It is possible to accumulate a large number of perceptual materials, thus forming the appearance, and further processing and upgrading, and then form a rational understanding of graphics, and a profound grasp of related concepts. But look back at our classroom. Some teachers in guiding students to operate, or just to form, or a little, not to make the operational activities become practical and effective. I think we should pay attention to the following points in the teaching. 1. To select the operating materials, we must follow our teaching contents and achieve
