在初中学生们学习了平面几何,为高中的立体几何教学奠定了一定的基础,但是立体几何对于很多学生来说还是数学学习过程中的一大障碍。学生进入高中初步接触立体几何,既感兴趣又感到头疼,很多同学在解答几何证明题时困难多多。学生有关立体几何的学习困难主要是平面几何的基础不扎实,缺乏自信心,空问想象力差,逻辑思维能力不强等等。本文针对这些原因提出一些有利于提高数学立体几何教学效果的方法。
Students in the junior high school studied plane geometry, which laid a solid foundation for high school geometry teaching. However, for many students, solid geometry is still a major obstacle to the process of mathematics learning. Students entering the high school initial exposure to three-dimensional geometry, both interested and felt a headache, a lot of students in the geometry proof questions to answer a lot of difficulties. Students on the three-dimensional geometry of the learning difficulties are mainly flat geometric foundation is not solid, lack of self-confidence, poor spatial imagination, logical thinking ability is not strong and so on. In view of these reasons, this article puts forward some methods which are helpful to improve the effect of mathematical three-dimensional geometry teaching.
