摘要

发展数学能力需要对数学词汇的理解。虽然以前的研究已经开发了几种不同年级数学词汇的测量方法，但没有一项研究只关注分数词汇。我们为四年级学生开发并测试了一套分数词汇量表，以确定该量表的内部一致性和难度水平。分析表明，测量结果具有较高的内部一致性。平均而言，学生正确回答的分数词汇不到三分之一。我们还检测了有数学困难和没有数学困难的学生、双语学习者和他们的同龄人之间的表现差异。

Development of a Fraction Vocabulary Measure

Developing mathematics proficiency requires an understanding of mathematics vocabulary. Although previous research has developed several measures of mathematics vocabulary at different grade levels, no study focused solely on fraction vocabularies. We developed and tested a measure of fraction vocabulary for students in Grade 4 to determine the internal consistency and difficulty level of such a measure. Analysis indicated the measure demonstrated high internal consistency. Students, on average, answered less than one-third of fraction vocabularies correctly. We also detected performance differences between students with and without mathematics difficulty and dual-language learners and their peers.

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.
