数学符号在数学课程中占据着重要的地位,《义务教育数学课程标准》要求学生掌握的运算符号、数学符号、推理符号每学期新增42个,45%的学生只懂得一个数学符号的一种含义,38%的学生在逐年次的学习过程中遗忘了所学过的数学符号。复杂的逻辑推理技巧都是通过在对符号的自我解读中锻炼出来的。对数学符号进行有效科学的阅读,在小学基础数学教育阶段显得尤为重要。学生只有充分读懂了题目的逻辑含义,才能有效地进行推理判断和纸上作答。
Mathematical symbols occupy an important position in mathematics curriculum. Compulsory education mathematics curriculum standard requires that the arithmetic symbols, math symbols and reasoning symbols mastered by students should be increased by 42 per semester, 45% of students only know one kind of math symbol Meaning, 38% of students forget the mathematical symbols they learned in year after year. Complex logical reasoning skills are tempered by the self-interpretation of symbols. Effective and scientific reading of mathematical symbols is particularly important in elementary mathematics education. Only when students fully understand the logical meaning of the subject can they reasonably judge and answer the questions effectively.
