数学来源于实际生活,又为实际生活服务,两者是相互依存,缺一不可的。国内外数学改革的经验也证明:完整的教学过程应分为抽象、符号变换和应用。但在以往的数学教学中,我们的数学却以单纯处理中段为原则,这导致了数学严重脱离实际的倾向。因此,强调数学抽象和数学应用已成为改革数学教学刻不容缓的当务之争。一、在实际生活中培养数学抽象能力小学生的思维特点以形象思维为主,他们的年龄、经验决定他们获得的绝大部分数学知识是在对具体形象事物的感受、感知的基础上逐步抽象出来。因此在教学时要注意让学生在生活实际中进行数学抽象,在抽象过程中认识数学知识和 Mathematics comes from real life, but also for real life services, the two are interdependent and indispensable. The experience of mathematical reform at home and abroad also proves that the complete teaching process should be divided into abstraction, symbolic transformation and application. However, in mathematics teaching in the past, our math was based on the principle of simply dealing with the middle segment, which led to a serious tendency of mathematics to deviate from reality. Therefore, it is emphasized that mathematics abstraction and mathematics application have become the urgent task of reforming mathematics teaching. First, in practical life to cultivate mathematical abilities Abstract thinking characteristics of primary school students based on the image of thinking, their age and experience determine the vast majority of their access to mathematical knowledge is on the specific image of the feelings, perception gradually abstract . Therefore, in teaching, we should pay attention to letting students make mathematical abstraction in the real life, understand mathematics knowledge in abstract process and
