数感是学习者对数量关系的一种感悟能力。新课标明确提出要培养学生的数感、符号感,提高学生的抽象思维能力。笔者认为,培养学生的数感要立足于重视学生学习的过程之上,需要教师采用有效的教学策略。一、与生活实际相结合,建立数感创设生活化的教学情境,让孩子们在发现问题、分析问题、解决问题的过程中探究知识。这样的数学探究活动,能有效培养学生对数的感悟能力,提高学生解决问题的能力。例如,在教学苏教版四年级数学上 Sense of number is a perception of the number of learners ability to sentiment. The new curriculum clearly proposed to develop a sense of the number of students, a sense of symbol, and improve students’ ability to abstract thinking. In my opinion, to cultivate the sense of number of students should be based on the emphasis on the process of student learning, teachers need to adopt effective teaching strategies. First, with the actual situation of life, the establishment of a sense of the number of teaching to create a living environment, so that children find problems, analyze problems, solve problems in the process of exploring knowledge. Such mathematical exploration activities, can effectively develop students ’perception of the number of logarithms, improve students’ ability to solve problems. For example, in the fourth grade of mathematics in teaching Sujiao
