The present study evaluated a systematic instructional package including the system of least prompts (SLP) to teach differentiation and selection of tangible symbols to continue activities for two children with complex support needs and deafblindness (DB). A multiple probe design across three symbols was used to evaluate the intervention package…

Teaching tact and intraverbal responses based on function-feature-class to children with language delays can result in the emergence of untrained relational responses. The purpose of this study was to compare the effects of compound stimuli in discriminated operants (i.e., different combinations of hear, see, touch, and taste) on the acquisition…

The geologic method of stratigraphy which studies the structure of the earth by making layers was employed with 3D laser cutting techniques to make more easily defined tactile regions in templates of cells, tissues and anatomic regions containing muscles and bones. Templates were made audio responsive by hand-drilling a small hole in a template…

Introduction: The emerging technology of three-dimensional (3D) printing has the potential to provide unique 3D modeling to support specific content in science, technology, engineering, and mathematics (STEM) education, particularly chemistry. Method: Seventeen (n=17) students with visual impairments were provided direct instruction on chemistry…

Recently, there has been a transition from traditional paper or computer-based learning environments to smartpad-based learning environments, which are based on touch and involve various cognitive strategies such as touch operation and note taking. Accordingly, the use of smartpads can provide an effective learning environment through…

The aim of the study was to conduct a systematic review in order to synthesize the evidence-based literature on mathematics education among students with visual impairment (VI). Studies were identified through searches of electronic databases (SCOPUS, PubMed, ERIC, and Web of Science). The authors included articles published between 1 January 2000…

The increasing use of visual diagrams in educational and work environments, and even our daily lives, has created obstacles for individuals who are blind or visually impaired to "independently" access the information they represent. Although physical tactile pictures can be created to convey the visual information, it is typically a slow,…

This study examined the usability of an assessment-for-learning (AfL) system that provides audio-tactile graphics for algebra content (geometric sequences) for individuals with visual impairments--two who are blind and two with low vision. It found that the system is generally usable as a mathematics AfL system. (Contains 4 tables.)

This qualitative multiple case study explored the conceptual frameworks of two congenitally blind male adolescents on the nature of matter. We examined participants' responses on four tactile investigations focused on concepts and processes associated with matter changes. The matter changes investigated were dissolution, chemical change,…

This article describes a lesson plan model that applies principles of universal design for learning (UDL) and multisensory learning centers to the framework of a traditional direct instruction spelling lesson for elementary students with learning, social, and attention problems. It reviews essential components of UDL and demonstrates how to…

The creative application of low-cost, readily available materials and techniques promotes inclusion and provides accessibility in the classroom and laboratory for students who are blind or have low vision. Difficulties encountered by these students include operation of laboratory equipment, execution of ordinary laboratory procedures, and use of…

This article describes the use of touch as a strategy to teach children with multiple handicaps. Touch cues help children to anticipate events and to interpret information from the environment. Caregivers should first observe the child's existing repertoire of movements, and then create touch cues that build upon the child's preferred…

This article offers a theoretical framework of a meaningful art education for blind people. Existing literature focuses on the interaction between the artwork and the blind person. This text describes this aesthetic encounter which is complex due to tactile sensations, individual differences of the non-sighted viewer and specific features of the…

A follow-up account of a mother's attempts to provide her blind daughter, now aged six, with knowledge of the physical world through the manipulation of three-dimensional objects and two-dimensional tactile representations. The case is made for the value of pictures to the development of children's understanding in general; and for the child who…
