Abstract

This study explores how hard of hearing students decided whether the shape was a polygon and which semiotic sources were used when the students engaged in explaining geometrical concepts. It was defined how the students interacted with geometric shapes using semiotic sources and examined how such multimodal interactions with geometric figures displayed their reasoning. The study was a case study and carried out three hard of hearing students. The data was collected through interviews and analyzed with content analysis. It was detected that the students paid attention to edge, angle, and vertex of the shapes in the process of identifying polygon. It was seen that the students used gesture, speech, sign language, inscriptions which are semiotic sources and personal or mathematical definitions to express polygon concept. However, it has been determined that students have some misconceptions in the process of explaining concepts. It is suggested that the words used in the concept definition should be selected carefully by the teachers to teach the concepts correctly and the teachers use hand signs for concepts in their lesson.

如何根据听力困难的学生多边形?符号学方法的研究

本研究探讨重听学生在解释几何概念时，如何判断形状是否为多边形，以及使用哪些符号学来源。它定义了学生如何使用符号学资源与几何图形互动，并检查了这种与几何图形的多模态互动如何显示他们的推理。该研究是一个案例研究，并进行了三个重听学生。通过访谈收集数据，并进行内容分析。发现学生在识别多边形的过程中，注意形状的边、角、顶点。我们可以看到，学生们使用手势、言语、手语、碑文等符号来源以及个人或数学定义来表达多边形概念。然而，已经确定学生在解释概念的过程中存在一些误解。建议教师在概念定义中仔细选择词汇，正确教授概念，教师在课堂上使用手势表达概念。

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.
