一、巧用视频展台,化静态教学为动态教学《数学课程标准》指出:“动手实践、自主探索与合作交流是学习数学的重要方式”。根据少年儿童的年龄特点和认知规律,注意通过实际操作,让每个学生在学习过程中都有动手操作的机会,通过多种感受参与学习过程,激发学生学习。动手操作,可以使学生获取大量的感性知识,使抽象的数学知识形象化,深化对知识的理解和掌握。在学习“空间图形”几何的知识时,一部分操作无法在黑板上演示,全凭 First, the clever use of video booth, static teaching for dynamic teaching “Mathematical Curriculum Standards” pointed out: “Hands-on practice, independent exploration and cooperation and exchange is an important way to learn mathematics.” According to the age characteristics of children and adolescents and cognitive rules, pay attention to through practical operation, so that each student has hands-on opportunities in the learning process, through a variety of feelings involved in the learning process to stimulate student learning. Hands-on operation allows students to acquire a large amount of perceptual knowledge, visualize abstract mathematical knowledge and deepen their understanding and mastery of knowledge. Part of the operation can not be demonstrated on the blackboard when learning the knowledge of “Spatial Graphics” geometry
