Abstract

Abstract -- In this paper, we report on creating an original gear-type radix converter for the purpose of understanding the fundamentals of radix conversion, in addition to understanding binary notation, which is the basic form of expression of computers. We also propose three ways to use the radix converter in a general information education class for freshman of universities. In addition to understanding radix conversions of the simplest positive integers, we propose its use for the purpose of gaining an understanding of the complement, and its use in comparison with the gear calculator in computer history. According to its trial use in FY2018 and questionnaire results of learners, learners generally have a good impression of the radix converter. In addition, it was found that the converter was useful to understand radix conversion.
