在图形与几何教学中,“空间观念”培养作为数学学习的核心概念之一明确进入我国的数学课程。在培养学生良好的实践、创新能力中,良好的空间观念有着十分重要的作用和意义,在学生步入初中阶段几何知识的学习中也起着不可估量的作用。因此,在教学中,作为数学教师应该注重学生良好的空间观念的培养。那么如何培养学生的空间观念呢?一、利用已有经验,创设体验环境空间观念可以从学生的现实生活经验出发,在现实的几何体
In the teaching of graphics and geometry, the cultivation of “space concept” as one of the core concepts of mathematical learning clearly enters the mathematics curriculum of our country. In cultivating students ’good practice and innovative ability, the good concept of space has a very important role and significance. It also plays an inestimable role in students’ learning of the geometric knowledge when they enter junior middle school. Therefore, in teaching, as a teacher of mathematics, we should pay attention to the cultivation of students’ good concept of space. So how to cultivate students ’space concept? First, the use of existing experience, the creation of experience of space concept can be from the students’ real life experience, in the reality of the geometry
