以问题为导向培养算法设计分析能力的教学探讨

Problem-oriented Teaching Discussion on Cultivating the Ability of Algorithm Design and Analysis

在学习了基本语言和数据结构的基础上,在学校里,学生继续学习算法设计与分析课程,可以参加多项比赛增强自己的能力,并在找工作时提升自身的竞争力。但算法本身存在难度,采用传统的讲授法会使得很多学生望而却步。因此可以采用以问题为导向,从实际生活中的例子,按照抽取问题,分析问题,探讨数据结构,实现算法,测试算法的准确性,一步步引导学生学习算法。在此基础上加深难度,引导学生尝试将所学的算法使用到竞赛中,帮助克服看到竞赛题如看到猛虎的心理。从而带领学生全面系统深入的学习算法,培养算法学习的兴趣,让他们加强专业学习的信心。

On the basis of learning the basic language and data structure,continue to learn the course of algorithm design and analysis in school,the students can participate in a number of competitions to enhance their ability and improve their competitiveness when looking for a job.However,the algorithm itself is difficult,and the traditional teaching method will deter many students.Therefore,we can adopt problem-oriented,from examples in real life,extract problems,analyze problems,explore data structures,implement algorithms,test the accuracy of algorithms,and guide students to learn algorithms step by step.On this basis, deepen the difficulty,guide students to try to use the learned algorithms in the competition,and help overcome the psychology of seeing competition questions such as tigers.So as to lead students to learn algorithms comprehensively,systematically and deeply,cultivate their interest in algorithm learning,and let them strengthen their confidence in professional learning.
