以往的数学教学中,对于知识的呈现一般都过于抽象、缺乏情境的铺垫,抑或脱离学生生活实际。在《数学课程标准(实验稿)》的“课程实施建议”中就提及“在具体生动的教学情境中学习数学”、“创设实际生活的情境,让学生体验和理解数学”。让小学数学知识的抽象和学生思维的具象能有机结合,深切地让我们感受为什么要学数学,学习数学的意义何在,同时增加课堂的趣味性,激发学生的学习兴趣。如何把数学知识的抽象性和小学生思维的具象性有机结合,解决
In the past mathematics teaching, the presentation of knowledge is generally too abstract, lacking the bedding of situation, or from the actual student life. In the Mathematics Curriculum Standard (Experimental Draft), the “Course Implementation Proposal” mentions that “learning mathematics in a concrete and vivid teaching situation”, “creating a real-life situation and allowing students to experience and understand mathematics ”. Let the abstract of primary school mathematics knowledge and the image of students ’thinking combine organically, deeply let us feel why we should learn mathematics, what is the significance of learning mathematics, meanwhile we should increase the interest in class and stimulate students’ interest in learning. How to combine the abstraction of mathematical knowledge with the concreteness of thinking of primary school students
