读了《数学教师》1993·6期廖小猛老师《浅谈初中数学中的未释概念》一文,给我很大启迪。原文指出:“所谓未释数学概念,指在教材中没有给出明确解释,但在教材中又出现或在教学中必须使用的概念”。并要求“教师在钻研教材时,应结合内容发掘出与之有关的未释概念”。 After reading the article titled “The Unreleased Concept in Junior High School Mathematics” by Teacher Liao Xiaomeng in the “Physician Teacher” period 1993·6, I was greatly enlightened. The original text states: “The so-called unreleased mathematical concept means that there is no explicit explanation in the teaching material, but it must be used in teaching materials or must be used in teaching.” And asked “teachers in the study of teaching materials should be combined with the contents of the relevant concept of unreleased.”
