“数制及数据表示”以史为据教学法

Teaching "The Number System and Data Representation" Base on the Historical Development

本文提出理论知识的教学可分为"以理为据"和"以史为据"两大类;展示了按照类似历史的发展方式来讲授数制及数据表示的教学方法。通过虚拟的历史发展来讲解权重,不需要使用复杂的数学推理,就能启发学生直观地理解数制转换方法。

This essay considers has two way of teaching： ＂according to the rationale＂ or ＂base on the historical＂. And demonstrate an example of teaching ＂The number system and data representation＂ base on the historical development. Through a virtual history of the development on weighting, do not needs to use complicated mathematical reasoning; students will be able to inspire a very intuitive understanding of the rules of the number system conversion.
