数学学科是数学语言和几何图形有机结合的概括体。几何直观能力反映了学生数学思维能力发展实际。在小学数学阶段,教师培养学生主体的几何直观能力,将抽象问题具体化,将复杂问题简单化,推动小学生更为科学、更为深入地解决问题。平面图形内容是其重要的章节部分,更是培养和训练小学生空间思维能力的重要载体。本文作者在此从数学知识素养教学、操作实践活动以及数形结合策略运用等三个方面,对小学生数学几何直观能力的培养,结合教学感悟,谈了自己的粗浅看法和实施举措。
Mathematics is a generalization of the organic combination of mathematical language and geometry. Geometry intuitive ability reflects the development of students’ mathematical thinking ability. In the elementary mathematics stage, teachers cultivate the students’ geometric intuition, concrete the abstract problems, simplify the complex problems, and promote the more scientific and in-depth solution to the problems for the pupils. Plane graphic content is an important part of the chapter, but also to train and train pupils space thinking ability of an important carrier. The author of this article from three aspects of mathematical knowledge literacy teaching, operational practice and the combination of number and shape of the three aspects of primary school students mathematical geometry and intuitive ability training, combined with teaching insights, talked about their own superficial views and implementation measures.
