数学集体教学活动中教师数学语言的运用:价值、现状与对策

The Application of Mathematical Languages in Collective Math Teaching Activity: Value, Current Situation and Countermeasures

数学语言在帮助幼儿理解数学概念、引导幼儿在程序性知识与概念性知识之间建立连接、促进幼儿数学思维发展等方面有着非常重要的作用。当下，数学集体教学活动中教师的数学语言存在忽视核心经验，语言内容贫乏，表征形式单一，交流形式不当等问题。基于数学语言的内涵及幼儿数学学习的特点，研究者认为，教师应当认真研习数学核心经验，运用精确、富有逻辑性并能体现数学之美的语言；选择易于幼儿理解的有一定开放程度的数学语言；运用内容丰富、形式多样的数学语言；创设宽松氛围，与幼儿进行深入的数学语言交流；努力做到数学语言学习与数学操作学习并重，为幼儿提供高效的支持与引导。

Mathematical languages play an important role in helping children understand mathematical concepts, guiding them to establish a connection between procedural knowledge and conceptual knowledge, and cultivating their mathematical think- ing. However, there are many problems in the use of mathematical languages such as ignoring the mathematical core experi- ence, lack of content, single forms of presentation, and inappropriate way of communication. Based on the connotation of the mathematical languages and features of children＇s mathematics learning, the researchers suggest that teachers should study the core experience, use precise and logical mathematical languages which are easier for children to understand. It is also important to create a stress free environment for children to communicate in mathematical languages. Both mathematical languages learn- ing and mathematical operation learning should be valued to support children＇s mathematics learning.
