Tactile graphics convert visual information into touchable patterns and braille, providing an essential solution for accessible graphics for individuals with visual impairments. Pioneering research advocates for the potential of audio-augmented tactile graphics, which convey complex information through auditory and tactile modalities rather than…

We taught three children with visual impairments to make tactile discriminations of the braille alphabet within a matching-to-sample format. That is, we presented participants with a braille character as a sample stimulus, and they selected the matching stimulus from a three-comparison array. In order to minimize participant errors, we initially…

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…

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,…

Analysis of completed surveys from 230 teachers of blind and visually impaired learners found that preservice training programs emphasizing the methodology of teaching Braille and the development of tactual perception tended to produce teachers who have positive attitudes toward Braille and feel competent in teaching Braille to children.

The author describes several teaching aids and techniques to help blind and partially sighted students understand electronics, specifically devices (with availability) he has found effective in preparing a blind student for a ham radio license: an audital multimeter, raised line drawings, Opticon, braille texts, and Speech Pulse Calculator.
