A study was conducted to determine if 61 visually handicapped students in grades 2-4 could discriminate the textures appearing on a cell model, could locate and identify the cross-sectional cell layers, and could manipulate the pull-apart features of the cell model. (SB)

An experimental lesson plan on sewing machine tension was developed for blind and sighted students in an attempt to teach this concept more effectively. Tactile/verbal aids were used in the experimental lesson to increase the potential for student comprehension. The experimental lesson produced better results for both groups of students even…

A study was conducted to evaluate the effectiveness of three-dimensional plastic models in teaching 71 visually handicapped students (in grades 1-3) to discriminate major body parts of insects, spiders, and earthworms. (SBH)

Describes a quantitative chemistry experiment, conductometric titration, which was adapted for a blind student. Indicates other areas which can be adapted for similar experiments. (TS)

Eleven basic types of visually displayed information that can be, and should be, rendered accessible to the visually impaired user are discussed. Speech, braille, and tactile technology are addressed as well as the innovative technique of "haptic-tactic" display combining a raised dynamic image of the screen's page with speech. (Author/DB)

Eighty-eight children (either totally blind or with residual vision) estimated directions between landmarks in a large scale layout of objects. Children experienced the layout either directly by walking around it or indirectly by examining a tactile map. Use of tactile maps considerably facilitated the performance of the blind children.

The ability of dyads with restricted access to the visual channel of communication to establish a reliable pre-linguistic communicative signalling system has traditionally been viewed as problematic. Such a conclusion is due in part to the emphasis that has been placed on vision as central to communication by traditional theory. The data presented…

The National Museum of Natural History of the Smithsonian Institution undertook a research project to determine what could be done to enable visually handicapped persons to benefit from the museum's resources. (Author)

One of a series of three resource guides concerned with communication, control, and computer access for the disabled or the elderly, the book focuses on hardware and software. The guide's 13 chapters each cover products with the same primary function. Cross reference indexes allow access to listings of products by function, input/output…

The paper reviews the effects of absence of vision on perceptual functioning and considers ways in which a modified Optacon (which translates images into tactile presentations) can help visually impaired persons acquire critical cognitive and perceptual knowledge. Background research with the Tactile Vision Substitution System, a system for…

This directory, in its revised and updated form, documents the existence of 46 braille music collections in 27 countries. The purpose of the directory is not to list specific braille music editions but to establish preliminary data that will facilitate the future compilation of an international catalog. Entries in the directory are arranged…

The guide provides accreditation standards for programs which transcribe printed matter into alternate media for blind and visually handicapped persons. Presented in a self study format, the booklet touches upon six aspects of the production of reading materials (sample subtopics in parentheses): planning and organization (administration,…

The article reviews the literature and presents principles for teaching foreign language in schools for the blind. Among principles are that blindness need not obstruct the process of learning a foreign language, that the best learning environment is a monolingual one, and that tactile and recorded materials can be integrated.
