An Audio-Tactile Curriculum to Support Visually Impaired Statistics Students.

数学(12)。理解和操作图形数据的能力对于掌握STEM学科至关重要。在统计学中，图形表示以图形和概率分布的形式说明数据模式；学生需要了解这些表示方式表示统计概念和数字表达式在掌握统计的重要。对于有视觉障碍的学生来说，将这些线索整合到一个认知整体中是一个很大的障碍。向盲人学生教授这些材料的教师常常发现自己不知如何继续下去。该项目对一套概念丰富的应用统计学入门课程模块进行调整、测试和传播，从而创建一个完全互动的、可访问的工作手册，供视力障碍学生和教授他们的教师使用。这种方法要求修改现有的文本，通过会说话的触觉平板电脑传递，这是一种新的低成本计算机外围设备，可以呈现触觉和大字体图形，并与音频描述相协调。媒体是互动的，学生可以随机访问文本、图形和详细的索引。制定指导方针是为了帮助其他机构的教师使用平板电脑格式开发自己的无障碍材料。该统计课件在项目完成后可在商业上使用。

Mathematics (12). The ability to comprehend and manipulate graphical data is crucial for mastery in STEM disciplines. In statistics, pictorial representations illustrate data patterns in the form of graphs and probability distributions; students need to understand the ways these representations denote statistical concepts and numerical expressions important in the mastery of statistics. For students who are visually impaired, bringing these strands into a cognitive whole presents a significant barrier. Faculty who teach this material to blind students often find themselves at a loss as to how to proceed.This project adapts, tests and disseminates a conceptually rich set of curricular modules for introductory applied statistics, thereby creating a fully interactive accessible workbook useable by students with visual impairments and the faculty who teach them.The approach calls for adapting an existing text for delivery via the Talking Tactile Tablet, a new low-cost computer peripheral that presents tactile and large-print graphics coordinated with audio description. The medium is interactive, and students have random access to text, graphics, and a detailed index. Guidelines are developed to assist faculty at other institutions who want to develop their own accessible materials using the tablet format. The statistics courseware is made commercially available through the completion of the project.
