This article describes practical lessons and experiences acquired as part of a journey in teaching a blind student at The University of Arizona to master the written and graphical language of first-semester organic chemistry and its associated concepts. These practical lessons include details on how to adapt an organic chemistry model set (with…

Purpose: This paper aims to evaluate the accessibility of digital information systems as a key usability attribute in information retrieval by users with visual impairment (VI), to inform development of accessible information systems. Design/methodology/approach: This study used a cross-sectional survey design based on the quantitative research…

Students with blindness or visual impairment face learning barriers in the typical higher education classroom where a great deal of information is conveyed visually. Instructors can use a variety of strategies to accommodate such students and make visually presented information accessible. One common and inexpensive strategy is the use of tactile…

Courses at the postsecondary level continue to rely heavily on visual material that is accessible only to fully or partially sighted students. Tactile graphics work for many pedagogical purposes, but in some cases are insufficient; other information and concepts may be better conveyed through haptic exploration of 3D printed objects. However,…

This study investigated the cognitive factors that impact the completion of mathematics problems, specifically algebraic-reasoning, by individuals who use tactile materials (i.e., braille) compared to those who use print materials. The inquiry investigated working memory, task time, cognitive load, efficiency, and the predictive quality of…

The TeX/LaTeX typesetting system is the most wide-spread system for creating documents in Mathematics and Science. However, no reliable tool exists to this day for automatically transcribing documents from the above formats into Braille/Nemeth code. Thus, visually impaired students of related fields do not have access to the bulk of study material…

This study illustrates how mathematical communication and learning are inherently multimodal and embodied; hence, sight-disabled students are also able to conceptualize visuospatial information and mathematical concepts through tactile and auditory activities. Adapting a perceptuomotor integration approach, the study shows that the lack of access…

This dissertation bridges the fields of haptics, engineering, and education to realize some of the potential benefits haptic devices may have in Science, Technology, Engineering, and Math (STEM) education. Specifically, this dissertation demonstrates the development, implementation, and assessment of two haptic devices in engineering and math…

This project investigated the provision of a set of core tactile and large print diagrams and supporting materials for degree level psychology study, containing diagrams that are central to the majority of UK psychology courses, as an alternative to providing many different bespoke diagrams for individual students. Interviews with 12 blind and…
