Code.org’s Hour of Code activities are one-hour tutorials designed to expose K-12 students to coding and other aspects of computer science. Although there are numerous Hour of Code projects, many are not accessible to students who are blind and visually impaired. However, there are two that utilize the Quorum programming language and are accessible.
Yes. For example, there is a community of individuals who are blind and use the Arduino platform to build hardware devices. Arduino allows users to build digital devices that can sense and control objects in the physical world.
Low vision is used to describe a loss of visual acuity while retaining some vision. It applies to individuals with sight who are unable to read a newspaper at a normal distance of viewing, even with the aid of glasses or contact lenses. People with low vision often need adaptations in lighting and/or enlarged print to read something. There are two specific types of low vision:
Tod Harris, a math and computer teacher at Maplewood Middle School in Edmonds, Washington, is committed to the universal design of classroom environments. His school serves students with visual impairments from throughout the district in general education classrooms. Some students were having difficulty accessing information projected on an overhead during class lectures and completing tasks in the math computer lab.
Mathematics and science are disciplines that have historically communicated ideas visually. This is especially true of formulas and equations, where relationships between parts are understood by their spacial relationship to one another. Communicating these same ideas to people who are unable to see poses significant challenges. However, a variety of solutions exist.
To accommodate students with low vision, use large print for text and handouts. While size will depend upon the needs of the individual, large print is usually defined as 16 to 18 point bold type depending on the typeface used. A standard Roman typeface, using upper and lower cases, is more readable than italicized, oblique, or condensed fonts. To enlarge print from standard 12 point original text to 16-18 point, use a 150-165% enlargement setting on a copier or printer.
Additional ways to accommodate students with low vision include:
Although each situation is different and the student is the best source of information regarding useful accommodations, the following are some accommodations that should help to make the laboratory safer for students with visual impairments and all of the students in your class:
For some people with visual impairments the standard size of letters on the screen or printed in documents are too small for them to read. Some people cannot distinguish one color from another. Fortunately, specialized hardware and software can make computer systems usable by individuals with visual impairments.
Most individuals who have visual impairments can use standard keyboards, but large-print keytop labels are sometimes useful, particularly when they are learning to type.
