摘　　要：工科基础课程往往由于数学公式多,理论推导复杂而使学生望而生畏,如何使得学生掌握学习方法,产生强烈的学习兴趣,成为迫切需要解决的难题。本文提出一种＂自顶向下,逐步求精＂教学方法。首先采取诱导方式提出问题,使学生理解所学知识的重要性,明确学习目的;然后采取逐层推进的方法对知识点细化,了解知识点的前后联系,强调物理意义,淡化数学公式的推导,强化数学运算技巧;最后以傅里叶变换的教学为例,具体说明这种教学方法的实际运用。Undergraduates are often horrified at the complicated mathematical formulas and perplexing theoretical deductions,so it is a pressing task to make the college students to adopt scientific learning approaches and be interested in the study. In this paper, a teaching method based on Top-down,Stepwise Refinement idea is presented. Firstly,introductory questions are addressed for the students to make them realize the importance of the knowledge they are learning,catch on the study goal. Secondly,the course is divided into small parts step by step,the connection of main knowledge points is learned,the physical meaning of some contents is emphasized,the deduction of mathematical formulas is weakened and mathematical skills are strengthened. Thirdly and lastly,an example of the teaching of Fourier Transformation is put forward to demonstrate the practice of this teaching method.
