小学数学“符号意识”渗透教学现状研究
摘要 “符号意识”是数学符号化思想的高度提炼，小学数学教师在教学中渗透“符号意识”有助于学生数学符号语言的学习，发展他们的符号感、逻辑思维与推理能力。本研究通过问卷法、访谈法等研究方法发现分析出的问题有：小学生对数学符号的意义掌握不准确、数学符号书写不规范、易对符号形成思维定势、不习惯对数学符号问题进行推理；小学数学教师对教材把握不全面、对课标的基本思想解读不深刻、教学红楼之锦绣纨绔组织方式攀登单一等。分享是一种美德主要原因在于学生对符号没有直接兴趣，无法把握符号的特征，教师对数学符号语言的使用没有做好正确示范，教学策略没有针对性，没有改变传统的教学方式等。因此我认为教师要在编排教学活动要中渗透符号思想，创设情境建构学生的符号储备，采用数形结合的方式帮助学生建立符号感，合理使用逐步渗透法帮助学生养成运用符号意识的习惯。

Rearch on the Teaching Status of "Symbolic Consciousness" in Primary School Mathematics.
动态图片格式Abstract "Symbol awareness" is a highly refined idea of 漫威经典台词mathematical symbolization.The primary school mathematics teacher permeates "the symbol consciousness" in the teaching to assist the student mathematics symbol language study, develops their symbol n, the logical thinking or the reasoning ability. The rearch found that the problems analyzed through questionnaires and interviews are: primary school students have inaccurate grasp 查电脑ipof the meaning of mathematical symbols, irregular writing of mathematical symbols, easy formation of thinking patterns for symbols, and are not ud to reasoning about mathematical symbols ; Primary mathematics teachers do not have a comprehensive grasp of the teaching materials, do not have a profound interpretation of the basic ideas of the cour standards, and have a single teaching organization method. The main reason is that students have no direct interest in symbols and cannot grasp the characteristics of symbols, teachers have not done a good demonstration of the u of mathematical symbol language, teaching strategies are not targeted, and traditional teaching methods have not been changed. Therefore, I think teachers should infiltrate the idea of symbols in the arrangement of teaching activities, create situations to construct st
udents' symbol rerves, u the combination of numbers and shapes to help students build a n of symbols, and u the stepwi penetration method to help students develop the habit of using symbol awareness.
