数学语言,是指对数学概念、定义、性质、法则、公式、图形、符号以及解题、证题的表述。就目前学生运用数学语言的错误来看,主要表现在如下几个方面:1.不能准确、完整地叙述概念。如有的学生叙述公式的基本性质“分式的分子和分母都乘以(或除以)同一个不等于零的代数式,分式的值不变”时,大多漏掉了“同”字。2.不善于用文字叙述数学内容。如有的学生在用方程解应用题时,不交代 x、y各表示什么,不写出答案,解题过程也无一字说明。
Mathematical language, refers to the mathematical concepts, definitions, nature, law, formulas, graphics, symbols and problem solving, the statement of the title. The current mistakes students use mathematical language, mainly in the following areas: 1. Can not accurately and completely described the concept. If some students describe the basic nature of the formula “fractional numerator and denominator are multiplied by (or divided by) the same algebraic not equal to zero, the value of fractional constant” most of the missing “same” word. 2. Not good at using text narrative math content. If some students use the equation to solve the problem, do not account for what x and y each said, do not write the answer, there is no explanation of the problem-solving process.
