数学是一门语言精辟、逻辑严谨的学科.数学语言是教师讲授知识、教育学生最直接的工具,具有准确性、逻辑性、专业性、简洁性.每个数学概念、符号、术语都有其精确的含义,没有含糊不清或易产生歧义的词汇.笔者作为数学教学一线的老师,在平时听课等活动中,经常听到一些教师的数学语言中出现错误,现列举几例.一、“若公元2012年记为+2012年,则公元前200年记为—200年.”在学习“正数与负数”时,常有数学老师说这样的话或出这样的题.虽说能帮学生理解“正数与负数可以表
Mathematics is a brilliant and rigorous discipline of mathematics.Mathematical language is the most direct tool for teachers to teach knowledge and educate students with accuracy, logic, professionalism and conciseness.Every mathematical concept, symbol and terminology has its own Accurate meaning, no ambiguity or easy to produce ambiguous vocabulary .As a front-line teacher of mathematics teaching, I usually hear some mistakes in the mathematical language of teachers in teaching activities such as listening to the usual, to name a few. ”If the year 2012 is marked as + 2012, the year 200 BC will be recorded as 200 years.“ When studying ”positive and negative“, there are often math teachers who say such words or questions. Can help students understand ”positive and negative can be table
