小学生空间观念和几何直观能力的培养一直是小学数学教学中的难点。在近几年的数学教学中,我深刻体会到了这一点,尤其是新课程改革后新增了很多内容,使学生理解起来比较困难。经过这几年的教学,我也有了一些自己的看法:发展学生的空间观念和几何直观方法是多种多样的,只要我们了解学生的知识结构,依据学生的年龄特点,遵循知识的循序渐进,注重使学生通过观察、操作、推理等手段,逐步认识,是可以做
The cultivation of primary school students’ concept of space and geometric intuition has been a difficult point in elementary mathematics teaching. In recent years of mathematics teaching, I deeply understand this point, especially after the new curriculum reform has added a lot of content, so that students understand more difficult. After these years of teaching, I also have some of their own views: the development of students’ spatial concepts and geometric intuitive method is varied, as long as we understand the student’s knowledge structure, according to the characteristics of the students age, follow the gradual and progressive knowledge, focus Make students through observation, operation, reasoning and other means, and gradually recognize that it is possible to do
