空间观念是人们指对物体的方位、距离、大小和形状的知觉。有了空间观念,人们就能根据需要,重现物体或图形的形象和特征,并将头脑中的表象进行加工和重新组合,进而促进空间想象能力的发展。学生的空间观念是在学习“空间与图形”的过程发展的,教学中,教师应以数学知识为载体,促进学生空间观念的发展。 The concept of space refers to people’s perception of the orientation, distance, size, and shape of an object. With the concept of space, people can recreate the image and features of objects or figures as needed, and then process and reassemble the representations in their minds so as to promote the development of spatial imagination. Students ’concept of space is in the process of learning “space and figure”. In teaching, teachers should promote the development of students’ space concept with mathematical knowledge as the carrier.
