scientific and graphing calculators

Do you know where to locate scientific and graphing calculators that can be used by blind students?

Calculators can be widely utilized in all educational level. Calculators are able to perform statistics or scientific calculations as well as manipulating matrices and plot functions on graphs are particularly suitable for studying advanced mathematics. Even though the majority of scientific calculators and graphing tools aren't available to those who aren't blind or unable to see properly. There are a few options for students that are visually impaired to utilize these devices successfully.

There are a variety of talking electronic calculatorsare available but no single calculator can be used at all educational levels. Therefore, a careful assessment of the features needed from the student must make sure the appropriate calculator for them is chosen. Susan Osterhaus at the Texas School for the Blind has put together a list of the functions of several talked scientific calculators which might aid in the process of making a decision. Orion Ti-30XS Talking Scientific Calculator Orion TI-30XS MultiView Talking Scientific Calculator is a very well-known a talkative scientific calculator that may meet the requirements of a wide selection of students.

Another alternative is to get an electronic notetaker that is portable and has advanced math functions. Certain notetakers have speech synthesis and Braille that can be refreshed and can be used by students who are blind for trigonometric and logarithmic computations. Verify with the manufacturer for confirmation whether there is a scientific calculator function is present.

There are also programs available which allows for speech access to a scientific calculator application. Some of these emulate the traditional calculator interface, and some even provide an audio interface for graphs. This program, called the Audio Graphing Calculator (AGC) is an example of an accessible Windows-based application and features the ability to interact with graphing calculators capable of displaying graphs visually as well as through the use of a sonified graph.

For more information on accessibility and access scientific and graphing calculators see the Accessible Calculators developed by the GeorgiaTech Center for Assistive Technology and Environmental Access (CATEA).
