摘 要: 离散数学内容丰富、概念多、定理多、抽象性强,加上很多留学生的数学基础比较薄弱、理解能力差,因此部分留学生学习兴趣低、学习困难。为此,提出对留学生离散数学的教学进行改革。改革的主要内容包括添加应用性教学内容、引入实践环节、建设题库和改革考核方式等。教学实践表明,这些举措有效地提高了留学生学习离散数学的兴趣、减轻了学习难度,培养了学生应用所学理论解决实际工程问题的能力。

Abstract: There are many concepts and theorems in discrete mathematics, and it is rather abstract. The mathematical foundation and understanding ability of many international students are not good enough, so some of them have low interest in learning discrete math. In order to solve this problem, the teaching reform of discrete mathematics for foreign students is proposed. The main contents of the reform include adding practical teaching contents, introducing practical links, building question bank and introducing new assessment methods, etc. Teaching practice shows that the proposed method can improve the interest of foreign students in learning discrete mathematics and reduce their difficulty of learning effectively. At the same time, the students' ability to solve practical engineering problems using theories is cultivated.
Key words: discrete mathematics; practical teaching; international student; learning interest

離散数学是现代数学的重要分支,在计算机理论研究及软、硬件开发的各个领域都有着广泛的应用。作为一门重要的专业基础课,离散数学所提供的训练有益于学生抽象概括能力、逻辑思维能力、归纳构造能力和创新能力的提高以及学生严谨、完整、规范的科学态度的培养。因此对于计算机大类的学生来说,学习离散数学具有极其重要的意义。
目前,我校招收的留学生数学基础普遍比较薄弱、理解能力差,而离散数学课程内容丰富,很多留学生反映这门课程定理多、概念多,而且抽象性极强。因此出现了部分学生学习困难、丧失学习兴趣的问题。针对这种情况,笔者进行了留学生离散数学实践教学改革,目标是从学生毕业要求出发,提高留学生学习离散数学的兴趣、加深学生对所学知识的理解、提高学生使用离散数学知识解决实际工程问题的能力。……
