《数学课程标准》提出:“要让学生在参与特定的数学活动,在具体情境中初步认识对象的特征,获得一些体验。”学生亲历的经验,有助于通过多种活动探究和获取数学知识,更重要的是学生在体验中,能够逐步掌握数学学习的一般规律和方法。教师要以新课标精神为指导,用活用好教材,创造性地教,让学生经历学习过程,感受成功的喜悦,增强信心,从而达到学会学习的目的。 The Mathematics Curriculum Standard states: “Students should be given some experience in participating in specific mathematical activities and understanding the characteristics of their subjects in specific contexts.” "The experiences experienced by students help to explore and acquire through various activities Mathematic knowledge, more importantly, students in the experience, to gradually grasp the general rules and methods of mathematical learning. Teachers should be guided by the spirit of the new curriculum standard, make good use of teaching materials and creatively teach them to experience the process of learning, feel the joy of success and enhance their confidence so as to achieve the goal of learning to learn.
