摘　　要：数制及转换是大学生学习计算机及相关知识必须掌握的重要内容。为了帮助学生更好的学习掌握这方面的知识,提出将"比较教学法"和"权值法"应用到教学中,讲解数制概念时,应用"比较教学法"深入浅出的把十进制和二进制等其他进制进行比较讲授,让学生从中发现规律,掌握规律、利用规律以便更好的理解数制;在数制转换中,应用"权值法"使数制转换变得简单、准确、高效,进而攻克数制转换中的难点问题,使学生能快速准确地解题。The number system and its conversion is the important knowledge content for college students in computer course. In order to help students better master the knowledge, the paper proposed two methods of ＂comparitive ap- proach＂ and ＂weight method＂, and applied them to the teaching process. When explaining the concept of the num- ber system, we applied ＂comparative approach＂ to analyze the character of decimal, and compared it with binary ＆octonary etc, so that students can discover and master the laws, and better understand the usage of the number sys- tem. In the number system conversion, the application of ＂weight method＂ make the conversion easy, accurate and efficient, and thus overcome the difficulties of number system conversion issues, so that students can solve problems quickly and accurately.
