摘  要：2001年，《全日制义务教育数学课程标准(实验稿)》发布，提出了“数感”，从此“数感"这个重要的概念明确进入我国数学课程，受到广大教育工作者的广泛关注。小学生数感的培养具有重要意义，培养数感不仅有助于提高学生的数学素养，培养学生的创新精神和实践能力，还能发展学生的心算和估算技能，提高学生的文化素养。

笔者运用问卷调查法和课堂观察法，辅以访谈法，发现小学生数感培养存在以下问题：教师对数感认识不足，教学方法简单，内容贫乏。造成这些问题的原因是：沉重的课时负担限制数感培养，落后的评价机制束缚数感的发展，小学生的认知特点制约数感培养，教师自身能力存在局限。笔者提出了以下对策以改善小学生数感培养现状：改革教师培养体制，提高教师整体素质；紧密联系生活，注重问题解决；强调算法多样化，加强估算教学；注重情境教学，让学生体验数感。

The current situation and improvement strategies of primary school students ‘Number Sense cultivating

Abstract：In 2001, the "full-time compulsory education mathematics curriculum standards (experimental draft)"clearly put forward the "number sense". At this point, the "number sense" explicitly as a new important content into the Chinese math curriculum for the first time, by the high degree attention of math educators. It is very significant to cultivate the number sense of primary school students. It is helpful to improve students 'mathematical literacy, cultivate students' innovative spirit and practical ability, develop students' mental arithmetic and estimation skills, and improve students' cultural accomplishment.

The author uses questionnaire survey and classroom observation, interviews, found that elementary school students' number sense cultivation exist the following problems: teachers' sense of logarithmic understanding is not enough, the teaching method is simple, the teaching content. The causes of these problems are: heavy class load limit number sense cultivation, lag behind the development of the evaluation mechanism of bondage number sense, restricted number sense to cultivate elementary student's cognitive characteristics, teachers' own capacity limitations. Aiming at the cultivation of primary school students, the author puts forward the following countermeasures: reforming the teacher culture system and improving the overall quality of the teachers. Close contact with life and focus on problem solving; Emphasizing the persity of the algorithm and strengthening the estimation teaching; Pay attention to the situation teaching, let the student experience.
