随着2001年新课程标准的实施,中学几何教学模式发生了相应的变化,在削弱几何证明技巧要求的同时,强调了发展思维能力与创新意识的培养,增强了学科之间的相互联系.新课标首次将几何变换、向量等知识引入中学课堂,增加了数学教学与学习的研究性.著名数学家华罗庚教授说过:“数形本是两依依,数缺形时少直观,形少数时难入微,数形相助双翼飞.”利用数形结合的思想可以帮助学生更直观的理解和解决与几何有关的
With the implementation of the new curriculum standard in 2001, the pattern of geometry teaching in middle schools has undergone corresponding changes. While weakening the requirements of geometric proofing skills, it emphasizes the cultivation of developing thinking ability and innovative awareness and enhances the inter-disciplinary relationship. For the first time, the curriculum standard introduces geometric transformations, vectors and other knowledge into the middle school classroom, which adds to the research of mathematics teaching and learning. Professor Hua Luogeng, a well-known mathematician, said: “Numbers are the two forms of dependence, When difficult to shape, digital help wings. ”The use of combination of ideas can help students more intuitive understanding and solution and geometric
