在新一轮课程改革中,强调几何变换,这不仅是内容上的变化,也是设计几何课程指导思想上的变化,这将是几何课程发展的一个趋势.让图形动起来,在运动或变换中研究、揭示、学习图形的性质,这样,一方面加深了对图形性质的本质认识,另一方面对几何直观能力也是一种提升.因此,充分利用图形变换去认识、理解几何图形,是培养几何直观的好办法.本文探讨旋转变换问题的教学.一、深刻理解概念,熟练运用性质.
In the new round of curriculum reform, emphasizing the geometric transformation, which is not only the content of the changes, but also the guiding ideological changes in the design geometry course, which will be a trend in the development of geometry courses.Get graphics, in the movement or transformation Researching, revealing and learning the nature of the graphic, so that on the one hand, the nature of the graphic nature is deepened, and on the other hand, the geometric intuitive ability is also improved.Therefore, to make full use of the graphic transformation to understand and understand the geometric figure is to train the geometry Intuitive and good way.This paper explores the teaching of rotation transformation.First, a profound understanding of the concept, proficiency in the use of nature.
