心理学研究认为,人们在进行思想交流与信息传递的过程中无不反映思维的认知方式。众所周知,人的思维方式来自于感知的习惯。感知是人获取外界信息的基本途径。小学生在学习数学过程中,对数字与数学符号的感知称之为数感。数感存在于数学学习的各个环节中,尤其对学生思维方式的影响是巨大的。因此,在小学数学教学中要通过帮助学生建立数感来培育其思维的深刻性。一、联系生活教学,在生活体验

Psychological studies suggest that people in the process of exchange of ideas and information all reflect the cognitive way of thinking. As we all know, people’s way of thinking comes from the habit of perception. Perception is the basic way for people to get outside information. Pupils in the process of learning mathematics, the perception of numbers and mathematical symbols known as the number of flu. Sense of number exists in all aspects of mathematical learning, in particular, the impact of student thinking is enormous. Therefore, in the primary school mathematics teaching to help students build a sense of the number to cultivate the profound nature of their thinking. First, contact life teaching, experience in life
