小学生思维的形象性、语言表述的随意或无意性在其认知过程中占很重要的地位。数学语言所特有的抽象性、概括性、简洁性、逻辑性,使小学生不能理解数学语言所表达的数学思想、数学思维方法,无法用数学语言清楚地表达自己的思考过程与结果,造成学习数学时遇到很多困难。“使学生真正理解和掌握基本的数学知识与技能、数学思想和方法,得到必要的数学思维训练,获得广泛的数学活动经验”(摘自《标准》),就必须提高学生数学语言表达能力。 The image of pupils’ thinking and the randomness or inadvertence of language expression play a very important role in their cognitive process. Mathematical language unique to the abstract, general, concise, logical, so that pupils can not understand the mathematical language expressed in mathematical thinking, mathematical thinking, can not be clearly expressed in mathematical language, their thinking process and results, resulting in learning mathematics I encountered many difficulties. “To enable students to truly understand and master the basic mathematical knowledge and skills, mathematical ideas and methods, get the necessary mathematical thinking training, access to a wide range of mathematical activities ” (excerpt from the “standard”), we must improve students’ mathematical language skills .
