新课标把空间概念作为小学数学教学的核心内容,而图形与几何知识是培养学生空间概念的重要内容。由于图形与几何概念具有抽象性和复杂性,对于小学生来说,不易深刻理解。计算机技术、多媒体技术、网络技术等现代信息技术能够把抽象复杂的几何图形转变为直观形象的内容,促进小学生图形与几何知识的学习,从而提高教学的有效性。一、运用信息技术创设教学情境,激发学习兴趣图形与几何概念教学更加注重抽象思维过程
The new curriculum standard regards the concept of space as the core content of primary school mathematics teaching, while the graphic and geometric knowledge are the important contents of cultivating the concept of student space. Due to the abstraction and complexity of graphics and geometric concepts, it is not easy for students to understand deeply. Modern information technologies, such as computer technology, multimedia technology and network technology, can turn abstract and complex geometrical figures into visual images and promote pupils’ learning of graphics and geometric knowledge so as to improve the effectiveness of teaching. First, the use of information technology to create teaching situations, stimulate interest in learning graphics and geometry concepts pay more attention to abstract thinking process
