Graphic Biology Laboratory Modules for the Blind.
Brooks, Austin E.
The goal of this project was to devise new methods of producing tactile facsimiles of microscopic images for the blind and visually impaired biology students at the secondary and college level. The numerous raised-line images that were produced were assembled along with brailled and large print student instructions, audio cassette tapes describing the lab materials and instructor suggestions into nine laboratory modules that include: microscopy, mitosis, leaf structure, algae, fungi, plant and animal cells, protozoans, stem structure, and root structure. The tactile facsimiles of microscopic views were made through the sequential combination of standard photomicrography, direct stencil photo silkscreening methods, and printing with heat polymerizable ink. Classroom testing under a variety of settings indicate that the durability, degree of relief and the detail of the raised-line facsimiles as well as the usefulness of the ancillary module materials was very good. Other important features of the tactile diagrams and photos produced using the new method include their low cost and portability. The potential of using the methods in other sciences (mathematics, physics, chemistry, geology, etc.) as well as non-science areas (geography, history, economics, psychology, etc.) is significant.
