Fractions are considered to be a complex concept as they are associated with part-whole, quotient, operator, ratio and magnitude interpretations, and have a range of representations. Evidence indicates that drawing attention to magnitude interpretations enriches learning opportunities, but the part-whole perspective dominates in England. One lesson on fractions from a larger video study in England is analysed here, where the teacher’s focus was the role of multiple representations. Whilst the students described fractions using language associated with a range of interpretations, the part-whole perspective remained central to the teacher’s management of classroom discourse; the implications for learning are considered.

会议纪要

分数被认为是一个复杂的概念,因为它们与部分整体、商、运算符、比率和幅度解释相关联,并且具有一系列表示。有证据表明,关注量级解释可以丰富学习机会,但部分整体的观点在英格兰占主导地位。此处分析了英格兰大型视频研究中关于分数的一节课,其中教师的重点是多重表征的作用。虽然学生使用与一系列解释相关的语言来描述分数,但部分整体的观点仍然是教师管理课堂话语的核心;考虑了对学习的影响。
