Introduction: The purpose of this study was to evaluate the differences in silent and oral reading speed, reading comprehension, and reading errors in two formats, large print paper and the iPad2, for students with visual impairments (that is, those who are blind or have low vision). Methods: A single-subject alternating randomized treatment design was used with three participants. The intervention consisted of instruction on the use of an iPad. Data regarding reading speed, reading miscues, and comprehension were collected. Data were analyzed visually and descriptively. Results: All participants demonstrated a slightly higher reading speed, equal comprehension rates, and decreased error rates using the iPad2 compared to paper. Discussion: Results indicated that using an iPad for reading may have an effect on reading fluency and comprehension for students with low vision. Implications for practitioners: Students with low vision, particularly those with more severe vision loss, may benefit from the use of electronic tablets that allow one to adjust font size, style, color, and contrast. Users should be taught how to manipulate the visual display of text and be allowed time to adjust to an electronic medium.

Over the last decade, many innovations have significantly changed the classroom. As a result, the authors believe the roles of vision professionals, primarily teachers of students with visual impairments, orientation and mobility (O&M) specialists, and braille transcribers, have likewise changed drastically in that time period. Although the core mission of these professionals remains advancing the independence and capabilities of individuals who are visually impaired (that is, those who are blind or have low vision), the scope of practice in the field of visual impairment has undergone shifts that require the attention of fellow practitioners and professional training programs. This thought piece is a result of observations from the field and discussions with fellow colleagues and stakeholders who are visually impaired, including a focused discussion held with attendees of the Association for Education and Rehabilitation of the Blind and Visually Impaired (AER) conference in the summer of 2016. This paper is not intended to reflect a stance but rather to open a discussion on updating professionals' roles within the field of educational and rehabilitative vision services. More specifically, addresses changes to the tools used to accomplish the mission of the field of visual impairment, the way its professionals instruct students and train future personnel, and the professional linkages that must be forged for members of the field of visual impairment to be successful in their work. Some of the principal changes discussed in this paper include: (1) the effect of ubiquitous computing on daily living and learning experiences; (2) the increased prevalence of multimedia in the classroom and community; (3) advancements in delivery options for accessible educational materials; (4) changes in the built environment (both physical and digital); and (5) the need for more transdisciplinary collaborations, including partnerships in the design, technology, engineering, and architecture fields.

This article describes and evaluates a technological approach to support a preservice teacher of visually impaired students with extremely low vision to conduct essential assessments for a learner with multiple disabilities and visual impairment with limited distraction to the child and classroom. The selected technology discussed here was purchased with funds provided by a departmental grant, but it would be relatively affordable to an individual living on the average salary of a teacher working in the United States. In addition, as the demand for streaming sports cameras and tablets rises, basic economics indicate that the cost of such items should continue to reduce. Experimental research is needed to address whether the technology described in this paper can be used to decrease distractions and increase the quality of assessments completed by teachers of students with visual impairments who are visually impaired themselves. Concurrently, other uses of live-streaming video and bug-in-ear communication could prove beneficial for other pre-service or professional teachers with visual impairments who may need assistance in working with learners with or without visual impairments and with or without additional disabilities for assessment, classroom management, or academic instruction.

Assistive technology is defined by the Individuals With Disabilities Education Improvement Act (IDEIA) of 2004 as "any item, piece of equipment, or product system, whether acquired commercially off the shelf, modified, or customized, that is used to increase, maintain, or improve functional capabilities of a child with a disability" (IDEIA, 2004). This broad definition includes devices and software that are beneficial in supporting the instruction of students with disabilities in special education (Duhaney & Duhaney, 2000). This paper reports on a study that examined special school teachers and their experiences with the assistive technology-assessment process in Singapore. Semi-structured in-depth interviews were carried out at the Lighthouse School, the only school for visually impaired students in Singapore. Four teachers of elementary grade students with visual impairments volunteered and consented to participate. An open-ended interview guide was developed to inquire as to how teachers considered assistive technology in their practice: How do you assess the assistive technology needs of your students? What processes does the school adopt in assistive technology consideration? Can you describe the decision-making process in acquiring assistive technology for your students? To what extent do you collaborate with partners to support assistive technology needs? The findings are summarized in four themes: making a decision, accessing assistive technology, working together, and increasing capacity. Overall, findings point to gaps in assessment, collaboration, and knowledge among teachers about assistive technology.

Students with multiple disabilities, such as severe to profound mental retardation combined with motor and visual impairment, are usually unable to engage in constructive activity or play a positive role in their daily context. Microswitches are technical tools that may help them improve their status by allowing them to control environmental events with small and simple responses suitable to their condition. Recently, a pilot study was conducted to assess such a program with a boy who had multiple disabilities, including total blindness and minimal motor behavior. The results were encouraging, in that the boy became quite active and chose stimuli he was expected to prefer and bypassed those he was not, thus exhibiting purposeful choice behavior. The present study reported in this paper served as a replication and extension of the pilot study, with two new students who had multiple disabilities. These students relied on a vocalization response to activate the microswitch as opposed to the eyebrow movements used in the pilot study. A computer system was used to handle sets of expected preferred and nonpreferred stimuli: it presented brief samples of the stimuli and eventually turned them on for longer periods of time if students selected them. The results of this study found encouraging evidence for the possibility of using specifically developed microswitch programs to enable individuals with minimal residual vision, limited motor behavior, and circumscribed intellectual ability to choose among environmental stimuli. Further research may help determine the generalizability of these results and assess ways of integrating different microswitch programs into the daily educational schedule of such individuals.

In addition to their restricted peripheral fields, persons with retinitis pigmentosa (RP) report significant problems seeing in low levels of illumination, which causes difficulty with night travel. Several devices have been developed to support the visual needs of persons who have night blindness. These devices include wide-angle flashlights, adapted military light-intensifier devices, and systems that use high-sensitivity (or infrared-sensitive) video cameras. New devices are also in development, including the Minified Augmented-View device, which incorporates expansion of the visual field, along with the enhancement of night vision, to address both the field and night vision needs of persons with RP. The study described in this paper was conducted to provide information about any difficulties in assessing outdoor night mobility in a real-world environment. The results are reported to open an avenue for discussion among professionals in the field. (Includes 3 tables.)
