Introduction: Across the world, mathematical expressions are represented very differently in braille. The aim of this study was (1) to gain an overall insight in mathematical braille notations and (2) to investigate how mathematical braille notations support braille readers in reading and comprehending mathematical expressions. Method: Twenty…

Background and Context: In order to fully include learners with visual impairments in early programming education, it is necessary to gain insight into specificities regarding their experience of and approach to abstract computational concepts. Objective: In this study, we use the model of the layers of abstraction to explore how learners with…

Introduction: Social skills are acquired primarily through imitation using the visual system. As a result, people with visual impairments may experience difficulties in this area at any age, which can have a major effect on their social participation and on their quality of life. The objective of this study was to systematically review the effects…

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…

Background: New technologies could broaden activities for people with profound intellectual and multiple disabilities (PIMD). This study compared watching television with a newly-developed interactive ball. Method: The ball responded with sounds, lights, and wiggling to the player's voice and movements. Five control sessions (watching television)…

A body of research indicates the importance of interventions for promoting the development and progress of children with visual impairments. However, the research available on suitable interventions for this population is relatively sparse. The purpose of this review is to identify, collate and appraise the available research evidence on…

Introduction: Braille readers encounter difficulties when reading mathematical expressions. In this exploratory study, we created a setting to investigate these difficulties. Method: Using a motion-capturing system, we analyzed the tactile strategies of three braille readers while they read mathematical expressions. To compare tactile with visual…

It is difficult to read mathematical expressions in braille, whether or not in coordination with text to speech (TTS) synthesis. The researchers in this study investigated the effect of an intervention on the braille readers' performance in reading and comprehending mathematical expressions as well as the braille readers' ability to make…

Background: People with profound intellectual disability experience a high prevalence of visual disability, making them more dependent on sound. However, research addressing the influence of the auditory environment is scarce. Method: Observations of the auditory environments (soundscapes) and moods of people with profound intellectual and visual…

Introduction: Despite the relatively high prevalence and challenges of visual impairments, limited funding is available for ophthalmologic research in the Netherlands. The research needs of people with visual impairments could aid the ophthalmological research community to optimally distribute research resources. The objective of the study…

The academic terms and the periods of the courses related to the language development and communication differs considerably in the programs of the countries which train teachers for the special education department. The aim of this study is to examine the contents and credits of the communication and the language development courses in Teacher…

When visually impaired students attend regular high school, additional materials are necessary to help them understand physics concepts. The time for teachers to develop teaching materials for such students is scarce. Visually impaired students in regular high school physics classes often use a braille version of the physics textbook. Previously,…
