Background: Despite anatomically correct models (ACMs) being recommended internationally for their ability to serve as real-life, age-appropriate, and practical models in comprehensive sexuality education (CSE) for learners with visual impairment, there is still limited research exploring South African teachers' views regarding their use.…

The prevalence of students with visual impairments varies across the United States, yet limited analysis exists on how many students receive special education services. The following study collected population data on students with visual impairments for the 2017-2018 school year and ran focus groups with state-level administrators to understand…

The purpose of this dissertation was to produce two manuscripts and a conference paper reporting on analyses of data from a survey that investigated the knowledge, beliefs, and self-perceptions of 236 teachers of students who are blind or visually impaired (TSBVIs) with regard to literacy instruction. The first manuscript investigated the…

BLV (blind low vision) students face difficulties when taking coding classes. Individual Development Environments (IDE) can be inaccessible which make it difficult if not impossible for BLV students to complete coursework. Alternative techniques are described which will allow a BLV student to successfully complete coursework. The author has found…

Introduction: Many tactile graphics designed for individuals with visual impairments consider single factors. According to the results of our previous study, there may be interactions among scale, representation, and complexity factors. We conducted this integrative study with these three factors. Additionally, for the representation factor, we…

Introduction: This study involved a systematic literature review to document the sources behind publications and citations that comprise knowledge about rates of braille usage/literacy among people with visual impairments in the United States. Methods: Predefined search criteria were used to extract publications that potentially mentioned claims…

Aim/Purpose: This paper proposes a new approach to developing a deep learning-based prototyping wearable model which can assist blind and visually disabled people to recognize their environments and navigate through them. As a result, visually impaired people will be able to manage day-to-day activities and navigate through the world around them…

The development of accessible elements in museum exhibitions is an important pursuit that needs a well-defined process. Educators at the Smithsonian National Air and Space Museum, working with accessibility professionals and blind or low-vision user/experts, discovered the value of co-designing tactile models with the people who would eventually…

Introduction: Proficient use of technology requires many intersecting skills including literacy, citizenship, advocacy, self-determination, and digital competence. In this study, the authors engaged experts in the field of visual impairment in focus groups with the purpose of defining digital competence, discussing issues related to visual…

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…

Background: Intellectual disabilities and autism are lifelong and often co-occur. Little is known on their extent of independent association with sensory impairments and physical disability. Methods: For Scotland's population, logistic regressions investigated age-gender-adjusted odds ratios (OR) of associations, independently, of intellectual…

A presumed setback in development between 16 and 27 months of age was studied by reviewing the literature on setback in development and longitudinal studies of children with blindness or visual impairment. The results showed that the period around the second year of life is a vulnerable period for these children, in which about 25-33% of the…

Childhood permanent, uncorrectable vision impairment (VI) is rare, yet it is a public health burden as the impairment lasts a lifetime. Vision impairment describes decreased vision that affects everyday activities. Acuity cut-points commonly used include 20/40, 20/60 or 20/70. Blindness often refers to legal blindness (best corrected visual acuity…

The experience of visiting a museum exhibition is inherently visual. Although blind and partially blind people are increasingly offered some access to collections through audio and tactile content and inventive and accessible programming, these initiatives are infrequent and often assume that the goal is to replace or compensate for the visitor's…

Programming education is strongly emerging in elementary and high school. Diversity and inclusion are important topics, however, insights on suited programming materials for younger learners with visual impairments are lacking. A wide range of programming materials for children exists, diverse in both what is being programmed (output) and how this…
