The Number Sense

Based on the research of children's computational estimation, the paper draw a conclusion: Number sense depends on computational estimation to some extent.

基于对六年级儿童的估算能力进行的调查分析，本研究得到这样的初步结论：数感只是在一定程度上依赖于估算。

Unlike those studies, this one shows that the link between number sense and maths ability is already present before the beginning of formal maths instruction.

与先前的研究不同，此次结果表明，在儿童接受正式的数学教育之前，他们的数字感和数学才能已经建立了联系。

This research feels two angles of view from the Estimation and the Number Sense, Take elementary school lower grade students as object of study.

本研究从估算和数感两个视角，以小学低年级学生为研究对象。

The cultivation of students number sense is basically the foundation of improving their capability of mathematics and the spirits of rationalism.

培养数感是提高学生数学能力和理性精神的基础。

The children have obvious difference in the sensibility of number sense;

儿童在数感情感上存在明显的差异；

It's called the Approximate Number Sense, or ANS.

它被叫做近似数字感，或者ANS。

Education Function of the Number Sense in the Mathematics Course

数学课程中数感的教育功能

Good number sense in adolescents was thought to be linked to good instruction, but turns out from this study that the link between good number sense and good math skills exists before any instruction.

人们曾以为青少年的数字意识离不开后天良好的教导，不过这项研究显示数字意识和数学水平的关系其实早就存在了。

Concerning our preference for numbers, a more recent study seems to show that even as adults, we may retain some instinct for the logarithmic number sense we had as babies.

就我们对数字的偏好而言，最近的一项研究似乎证明，即使我们已经成年，可能仍保留着一些婴儿时期拥有的对数意识本能。

Using sign express quantity relationship is the weak among the five components of number sense. So the component should enhance in practical mathematical teaching.

在符号意识的五个组成成分中，用符号表示数量关系表现最弱，这有待于在数学教学中进一步加强。

However, the difficulty of this study is how to prepare the number sense test.

其中，数感测试卷的编制是本研究的难点所在。

The number sense deletion type is the most important but serious one, if students do not abandon their wrong conception, the development of their number sense will be influenced, even their other mathematics ability.

数感缺失型是三种错误类型中最重要，也是最严重的一类，若不能改正其错误概念，则会影响其数感的发展，甚至影响其他数学能力的发展。

The size and the number of the sense buds increased as young fish grew.

味蕾的大小随仔鱼日龄的增加而增大，其总数随鱼个体长大而增多。

With the expansion of the number of awareness, the number sense of students being significantly enhanced, for ability to computational estimation the development laid a good foundation. 3.

随着数认识的拓展，学生的数感水平明显增强，学生的估算技能良好，为估算能力发展打下良好基础3.学生的估算意识非常薄弱。

Teachers must emphasize six developments of students in enforcing the new course of math teaching. The sense of number is an essential math attainment;

教师在实施数学新课程教学中要注重学生的“六个发展”：一、数感是人的一种基本数学素养；

The resources of back number of journals and magazines are restricted to the sense, opening extent and service form, their real value has not been able to get fully development and utilize.

过刊资源由于受观念、开放层面、服务形式的限制，使其真正的价值未能得到充分发掘和利用；

It was important to, by realizing the importance of number sense in mathematics education, cultivate a number sense among the students in the teaching of number concept, in the teaching of number manipulations and in the guidance of student problem solving processes.

在数概念教学与数的运算教学中，在指导学生解决现实问题的过程中培养学生的数感。
