根据课改新理念要强化学生辩证思维能力的研究,许多教师发表了有关这方面的文章.特别是写有关微积分是提升学生数学思维与方法的能力的最理想内容的文章很多.众说纷纭,归纳起来不外乎是:由于微积分不但研究常数,而且还涉及到变量与常量的相互转化;由于微积分中引进了“以直代曲”的思维等等.各有其理,但要么只谈了局部的理由,要么只作了浅层面的说明.鉴于此,笔者 According to the new concept of curriculum reform to strengthen students ’ability to study dialectical thinking, many teachers published articles in this area, especially writing about calculus is the ideal content to enhance students’ ability of mathematical thinking and a lot of articles. It is nothing more than that: since calculus not only investigates constants, but also relates to the mutual transformation of variables and constants; since the introduction of calculus in the “straight song” and so on. Each has its own reasons, but either Only talked about the local reasons, or only made a shallow description. In view of this, the author
