小学空间与图形的课程核心目标在于,促进学生积累丰富的几何活动经验,培养学生的空间观念、形象思维和初步的推理意识。然而,在实际教学中老师往往重视学生掌握有关空间与图形的知识、技能,而忽视发展学生的空间观念、形象思维和推理意识,背离了空间与图形教学的核心价值。 The core goal of the curriculum of primary school space and graphics is to promote students to accumulate rich experience in geometric activities and to cultivate students’ space concepts, image thinking and preliminary reasoning. However, in practical teaching, teachers often attach importance to students ’mastery of the knowledge and skills of space and graphics, while neglecting the development of students’ concept of space, image thinking and reasoning, deviate from the core values ​​of space and graphic teaching.
