在数学问题情境中注意数字所指的整个单位,灵活地协调不同单位是数学理解的基础。本研究旨在探讨教师在分数和分数乘法情境中对所指单位的注意和灵活性。使用收集的数据从美国各地的246名数学教师在3-7年级的分数教,我们发现,教师的注意力和灵活性与参考单位是相互关联的,以及教师的整体知识的分数。
Attending to the whole unit that a number refers to in a mathematical problem situation and showing flexibility in coordinating different units are foundational for mathematical understanding. In this study, we explored teachers’ attention to and flexibility with referent units in situations involving fractions and fraction multiplication. Using data collected across the USA from 246 mathematics teachers in Grades 3–7 where fractions are taught, we found that teachers’ attention to and flexibility with referent units were related to each other as well as to teachers’ overall knowledge of fractions.
