Abstract

The goal of this article is to introduce the revised Conceptual Understanding Weighting System (CUWS) Greene & Shorter (2012, Trans. Dial.), a tool for categorizing and weighting a mathematical task in order to identify the level of conceptual understanding being assessed by the task. In addition, there is discussion of how this weighting system relates to other frameworks that are currently used to classify mathematical tasks and student reasoning. Examples are provided to demonstrate how the revised CUWS can be used to calculate a conceptual understanding score for a particular exam, to create mathematical tasks that assess understanding at different levels and to analyse student understanding within those different levels. This in turn allows instructors to identify concepts with which students are struggling and quickly adapt classroom activities to improve students’ understanding. The ability to use the CUWS to create mathematical tasks (not just categorize them) is one of the important goals of the CUWS and one that is not regularly emphasized when working with other frameworks to categorize mathematical tasks.

概念理解权重系统：一种有针对性的评估工具

本文的目标是介绍修订后的概念理解加权系统（CUWS）Greene&Shorter（2012，Trans.Dial。），这是一种用于对数学任务进行分类和加权的工具，以确定任务评估的概念理解水平。此外，还讨论了这种加权系统如何与目前用于分类数学任务和学生推理的其他框架相关联。提供了一些例子来演示如何使用修订后的CUWS来计算特定考试的概念理解分数，创建评估不同水平理解的数学任务，并分析学生在这些不同水平上的理解。这反过来又使教师能够识别学生正在挣扎的概念，并快速调整课堂活动以提高学生的理解力。使用CUWS创建数学任务（而不仅仅是对它们进行分类）的能力是CUWS的重要目标之一，在与其他框架合作对数学任务进行分类时，这一点并没有得到经常强调。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
