高考结束,本打算对一年的高考复习做些回顾,恰在这时,收到了《中学数学教学参考》第6期,并拜读了文卫星老师的《在双基模块的基础上构建双基平台一一高三复习课“抽象函数”教学实录》一文(以下简称《抽》文),由此激起了我对“抽象函数”教学的再思考.抽象函数问题是高中数学函数部分的难点,也是高中与大学函数部分的衔接点.由于抽象函数试题既能全面地考查学生对函数概念的理解及性质的代数推理和论证能力,又能综合考查学生对数学符号语言的理解和接受能力.以及对一般和特殊关系的认识.从而对考查学生的创新精神、实践能力和运用数学的能力,有着十分重要的作用,因此,这类试题在近年的高考中不断出现.然而,由于这类问题本身的抽象性及其性质的隐蔽性.大多数学生在解决这类问题时,感到束手无策.为了提高学生的应对能力,大部分高三数学教师在组织复习时都会通过专题形式复习这部分内容,但在复习时,如何把握抽象函 The end of the college entrance examination, the college entrance examination review intended to do some review, just at this time, received a “high school mathematics teaching reference” No. 6, and read the text satellite teacher “on the basis of double-base module to build double Platform ”one by one high school review“ abstract function ”teaching record“ one article (hereinafter referred to as ”pumping“ text), which aroused my rethinking ”abstract function " teaching abstract function problem is high school mathematics function Part of the difficulties, but also the high school and university function part of the convergence point.Because the abstract function test can not only fully examine students ’understanding of function concepts and the nature of algebraic reasoning and argumentation ability, but also a comprehensive examination of students’ understanding of mathematical symbols and language Ability to accept, and knowledge of general and special relationships, and therefore plays a very important role in examining students’ innovative spirit, practical ability and ability to use mathematics, therefore, such exams continue to appear in recent years of college entrance examination. However, due to Most of the students feel helpless in solving such problems.In order to improve students’ coping ability, most of the senior students Teachers in the organization review will be through the thematic form of this part of the review, but in the review, how to grasp the abstract letter
