摘要

我们讨论了即将重新定义的国际单位制可能会如何影响学生理解单位与新系统之间联系的能力。重新定义将不再定义一组基本单位，而是定义一组自然常数，如基本电荷e。我们指出，无论是在课堂上还是在教科书中，这一常数列表都不一定是向学生介绍这一主题的唯一方式。我们建议了一种替代方法，通过建议一些单元的实验列表，向高中生和本科生介绍重新定义的SI；这个列表将与重新定义的SI完全兼容，并具有所有相同的科学和技术优势。我们通过问卷调查结果表明，这种选择对学生更具吸引力。我们希望在老师之间就高中和本科物理课程的这一重要话题展开讨论。

"What is The SI?" A Proposal for an Educational Adjunct to the Redefinition of the International System of Units.

We discuss how the impending redefinition of the SI system of units might affect the ability of students to understand the link between the units and the new system. The redefinition will no longer define a set of base units, but rather a set of constants of nature, such as the elementary charge, e. We point out that this list of constants need not be the only way to introduce students to the subject, either in class or in textbooks. We suggest an alternative way to introduce high school and undergraduate students to the redefined SI, by suggesting a list of experiments for some units; this list would be completely compatible with the redefined SI, and would have all of the same scientific and technological advantages. We demonstrate by questionnaire results that this alternative is more appealing to students. We hope to spur a discussion amongst teachers regarding this important topic for high school and undergraduate physics courses.

期刊介绍： The Journal of Research of the National Institute of Standards and Technology is the flagship publication of the National Institute of Standards and Technology. It has been published under various titles and forms since 1904, with its roots as Scientific Papers issued as the Bulletin of the Bureau of Standards. In 1928, the Scientific Papers were combined with Technologic Papers, which reported results of investigations of material and methods of testing. This new publication was titled the Bureau of Standards Journal of Research. The Journal of Research of NIST reports NIST research and development in metrology and related fields of physical science, engineering, applied mathematics, statistics, biotechnology, information technology.
