Technology
for Visually Impaired Students
Technology used to educate the visually impaired has not
always been around. However, with the
rapid advancement in our technology world, the available technology for the
blind or nearly blind students has been increasing. The available technology for the visually
impaired is different from what it was 10 years ago, and has been changed to be
more efficient for the students. It has become a key factor to advancing
teaching and learning for students who have no, or low, vision. The specialized technologies to assist
visually impaired or blind students vary according to different needs. It ranges from devices such as telescopes and
binoculars that allow them to see what the teacher is writing on the board to
more highly adapted devices that help them function as a normal student (Ring).
There is wide variety of available tools for visually
impaired students. Among them, there is
the Speech Assisted Learning System (SAL2) which uses audio to teach blind
students Braille. The SAL2 runs on
TouchGraphic’s Talking Tactile Table (TTT) that presents a way for students to
experience programs that teach reading, writing and arithmetic, while recording
their performance. The program is
important because it allows blind students to learn with little or no help from
an instructor, which is often needed when dealing with visually impaired
students (Assistive
Educational Technology).
Another more technological advanced device is Braille Lite. Braille Lite offers blind students a way to
take notes in their class. The students
can check what they have written by a Braille display on the front or choose an
extra function where it reads their notes aloud. Whenever the students are done, they can hook
up the Braille Lite into a PC, and choose to print out their notes in large
font or in Braille (Ring).
Due to the convenience of students, tools that are used
at home versus in school differ in functions. Students attending Brooklyn’s
Edward R. Murrow High School, a school for visually impaired and blind
students, use closed-circuit televisions (CCTVs) called an Aladdin Apex. It magnifies items under a camera, and is
available in different sizes that fit the need and circumstances of the
students. In the school, students are to
use two software programs, Magic Screen Magnification and JAWS screen reader,
to help them write papers. It provides
speech options that read texts at different speeds (Ring).
Another tool used by visually impaired students is
accessible e-learning. Helen Armstrong
and Iain Murray composed an experiment where lectures in class were recorded
and put into files for a virtual classroom website that could be accessed by
students any time they wanted (506). It
was designed to advance skills in information technology for adult students who
were legally blind and preparing for employment. In the conclusion of their research, it
suggested that, “given accessible e-learning materials, adult students who are
visually impaired can achieve results similar to sighted students” (509). Their results also showed that in two out of
the three group summaries comparing
average grades for visually impaired and sighted students, the visually
impaired had a higher percentage than the sighted group (508).
Although
their research proved that given the technology needed, visually impaired
students were able to learn the same as a normal student, according to small
scale research done, the percentage of visually impaired students in primary
and secondary public schools not being taught to use assistive technology are
higher than what professionals had assumed. The research conducted showed a
percentage as high as 40 percent, of elementary and middle school students that
were visually impaired and blind, not using assistive technology in their
school (Kelly).
This
may be due to the expense of the assistive technology. An example of an expensive device used is The
Speech Assisted Learning system discussed earlier. The SAL2 needs an approximately $699 TTT, a
$219 Power Chord Braille Keyboard, and activities that range from $49.95 to
$349 per program (Assistive Educational Technology). Research done by Armstrong and Murray also
found that their solution to their report was expensive and ineffective (507).
However, cost is not always the case Miriam Bazeley, a coordinator of the
vision unit for Murrow’s Blind and visually impaired students states that his
“kids don’t want to stand out in class” (Ring). He talks about how they have devices that
could be used by the visually impaired students so they could see the black
board, but he doesn’t have them in his class, because the students will not use
them in fear they will look too “geeky” (Ring).
For
many students who are visually impaired, finding the right technology that fits
their needs and convenience has been a rocky ride. Adam Linn, a junior attending Harvard
University, lost his sight when he was a 4th grader. When he was in 7th grade, he used
a six-key brailler to take notes and write his assignments in the classroom
however, it became a problem to the other students because it was very
loud. Adam then turned to an expensive
1986 microbrailler, hoping he would have a more efficient piece of
technology. It turned out that the
machine would malfunction and never did live up to Adam’s expectation. He now uses a laptop with speech feedback,
and has found ways to access information he needs to write by using Braille and
recordings. Adam believes that “Human
support is infinitely more important than technological support” (Corley).
In conclusion, technology has advanced learning for students
who are visually impaired. Scientists
that continue to advance the accessible technology for the visually impaired
and who help technology become more efficient have helped visually impaired
students in their daily life, as seen by Adam’s story. They help blind or
nearly blind students live as normal people do, continue with their life, and
find employment with help from e-learning and assistive technology. Even if it’s just simple as binoculars,
technology helps a great deal for students who are unable to see. Unfortunately, the new technology today may
not be available for all students because of the cost. However, if the visually impaired or blind
students were given the right tools and devices, they would be able to learn
just like students with sight.
