谈起字、词、句的教学,人们都认为是语文教师的事.尽管数学中的定义、定理、法则等,必须借助于文字表述,数学教师却很少有讲解文字的兴趣,他们的注意力集中在图形、符号、字母、数式上.这不能不说是一种普遍的疏忽.数学知识既然用文字来表述,准确理解文字就应当是掌握知识的起点.我曾经移植语文教师的手段来讲数学课本里的阐述性文字,收到了良好的效果.将 Talking about the teaching of words, words, and sentences, people think that it is a matter of language teachers. Although the definitions, theorems, rules, etc. in mathematics must be expressed in words, mathematics teachers rarely talk about the interest in writing. Their attention. Focus on graphics, symbols, letters, and numbers. This can not be said to be a general neglect. Since mathematics knowledge is expressed in words, understanding words accurately should be the starting point for mastering knowledge. I used to transplant language teachers The explanatory text in mathematics textbooks received good results.
