新教材给了学生更多观察动手的机会,让抽象的几何知识直观化,引进平移、翻折、旋转和中心对称等图形运动,这一系列的图形运动使枯燥的不动的图形变“活”了,有了生命力,产生了吸引力。新教材用先进的教学思想强调渗透式学习方法,更加突出探究,以提高主动性获取知识的能力。新教材中的几何,实际是以实验为主线的“实验几何”。作为教师就要挖掘出“实验几何”的功能,更好地为教学服务。
The new textbook gives students more chances to observe and visualize the abstract geometric knowledge and introduce graphical movements such as translation, flipping, rotation, and center symmetry. This series of graphic movements make the boring, Live “, with vitality, has attracted the attraction. The new teaching materials emphasize the penetrating learning method with advanced teaching ideas, and make the exploration more prominent so as to enhance the ability of initiative to acquire knowledge. The geometry of the new textbook is actually based on the experimental ”experimental geometry.“ As a teacher, we must dig out the ”experimental geometry" function, to better serve the teaching.
