The new mathematics curriculum yells mathematics teachers change traditional teachers" roles to nowadays teachers" roles. By analyzing the abuse of the traditional teachers roles and the requests about mathematics teachers which the new mathematics curriculum puts forward, we discover that from the lay of curriculum , mathematics teachers should actualize three facets changes as follows:from the single initiators of mathematics knowledge to the promoters of mathematics diathesis;(2)from the loyal executors of mathematics textbook to the devisers of mathematics instruction;(3)from the indoctrinators of mathematics knowledge to the organizers, guiders and participators of mathematics activity .

数学新课程呼唤数学教师由传统的教师角色向现代教师角色转变，通过分析传统数学教师角色的弊端及新课程对数学教师提出的要求，发现从课堂层面讲，数学教师角色主要要实现以下3方面的转变：(1)由单一的数学知识传授者向数学素质的促进者转变；(2)由教科书的忠实执行者向数学教学的设计者转变；(3)由数学知识的灌输者向数学活动的组织者、引导者和合作者转变。

The study shows that generally the mathematics view of normal university students majoring in mathematics is right, they depict mathematics learning as a dynamical process. Besides some special traits belong to mathematics, estimation, measurement and decision making themselves are also in the math field; however there are still some people warp the mathematics view, believe that mathematics is an apodeictic collection. Haven't realized the power that mathematics can improve people's taste ability and perfect people's personality, they believe that math learning is a passive process during which students receive acknowledge. What is more, there are different believes existing in the understanding of mathematics essence, mathematics value and mathematics learning. These believes vary with different university students from different grades and genders.

The new curriculum emphasizes mathematics and the real life relation, but also proposed specially mathematics teaching is mathematics activity teaching, is also lets the student career mathematization process the activity, lets the student embark from own mathematics reality, catches mathematics question with mathematics judgment in the life, utilizes mathematics knowledge analysis life phenomenon on own initiative, thus solves the actual problem which independently in the life meets.

新课程强调数学与现实生活的联系，还特别提出了数学教学是数学活动的教学，也就是让学生经历数学化过程的活动，让学生从自己的数学现实出发，用数学的眼光在生活中捕捉数学问题，主动地运用数学知识分析生活现象，从而自主地解决生活中所遇到的实际问题。

Moreover the thesis analyse specificness of the new system in details:The process of Mathematics learning strategies.The colony of Mathematics learning strategies.The activities of Mathematics learning strategies.The individuality of Mathematics learning strategies.The modernnization of Mathematics learning strategies.The new system of mathematics learning cant apart from the firm theory foundation.

本文在对《标准》的总体目标及学习目标进行分析的基础上，构建了《标准》指导下的新的数学学习策略的体系，并分析了新的数学学习策略所呈现出的新的特点：——数学学习策略的过程性；——数学学习策略的群体性；——数学学习策略的活动性；——数学学习策略的个体性；——数学学习策略的现代化；构建新的数学学习策略体系离不开坚实的理论基础。

This thesis is based on understanding and analysis of educational theory of Freudenthal's thought of mathematics education. It does analytical and Practical research on mathematics teaching in kindergarten in an effort to provide the thought and approach for reference. The intention is to Promote the kids to study mathematics efficiently,to master it comprehensively and to use it properly. At the same time,it also offers some constructive suggestions to the present mathematics teaching reformation.
